Frankie graphs the system of equation to determine its solution.
Y = 3x
Y = -x + 4
What is the correct solution?
Please explain step by step to get marked as brainliest
Answer:
To solve this system of equations, we need to find the values of x and y that make both equations true at the same time.
One way to solve this system is to use the substitution method. We can start by setting the two expressions for y equal to each other:
3x = -x + 4
Then we can solve for x by adding x to both sides and simplifying:
4x = 4
x = 1
Now that we know the value of x, we can substitute it back into either of the original equations to solve for y:
Y = 3x
Y = 3(1)
Y = 3
Therefore, the solution to the system of equations is (x, y) = (1, 3).
Solve: (x - 10)² + 10 = 100

A linear function contains the following points x 0 2 y -4 5
What are the slop and y intercepts of this function
The features of the linear function in this problem are given as follows:
Slope: 4.5.y-intercept: y = -4.How to obtain the slope and the intercept for the linear function?The slope of a linear function represents the rate of change of the output variable y relative to the input variable x.
Hence, if we are given two points in a linear function, the slope is calculated as the division of the change in y by the change in x.
The two points for the function in this problem are given as follows:
(0, -4) and (2,5).
Hence the slope of the function is calculated as follows:
m = (5 - (-4))/(2 - 0) = 9/2 = 4.5.
The intercept of a linear function is given by the value of y when the graph of the function crosses or touches the y-axis, that is, the value of y when x = 0. One point for this problem is (0,-4), hence the intercept is given by y = -4.

Jane is having difficulty deciding whether to put her savings in the Mystic Bank or in the Four Rivers Bank. Mystic offers a 12% rate compounded quarterly, and Four Rivers offers 14% compounded semiannually. Jane has $40,000 to invest and expects to withdraw the money at the end of five years. The better deal is:
Multiple Choice
Four Rivers because she will earn about $6,442 more.
Four Rivers because she will earn about $6,523 more.
Four Rivers because she will earn about $4,000 more.
Four Rivers because she will earn about $20,000 more.
Answer:
The answer is option (C). Four Rivers Bank
Explanation:
a). The total amount Jane will receive after 5 years after investing $40,000 in the Mystic Bank can be expressed as follows;
A = P (1 + r/n) (nt)
where;
A = the future value of the initial investment
P = initial investment amount/principal amount
r = the annual interest rate
n = the number of times that interest is compounded per unit t
t = the time the money is invested for
In our case;
P=$40,000
r=12/100=0.12
n=interest is compounded quarterly which is four times a year=4
t=5 years
Replacing values in the formula;
A=40,000(1+0.12/4)^(4×5)
A=40,000(1+0.03)^20
A=40,000×1.806
A=72,244.45
The total amount Jane will receive after 5 years if she chooses to invest with the Mystic Bank is $72,244.45
b). The total amount Jane will receive after 5 years after investing $40,000 in the Four Rivers Bank can be expressed as follows;
A = P (1 + r/n) (nt)
where;
P=$40,000
r=14/100=0.14
n=interest is compounded semiannually which is two times a year=2
t=5 years
Replacing values in the formula;
A=40,000(1+0.14/2)^(2×5)
A=40,000(1+0.07)^10
A=40,000×1.967
A=78,686.05
The total amount Jane will receive after 5 years if she chooses to invest with the Four Rivers Bank is $78,686.05
c). The best deal would be to invest with Four Rivers Bank for 5 years since the total amount Jane will receive after 5 years will be $78,686.05 which is greater than $72,244.45, which is the total amount she will receive if she chooses to invest with Mystic Bank

Assume that a normal distribution of data has a mean of 19 and a standard deviation of 5. Use the 68-95-99. 7 rule to find the percentage of values that lie about 29.What percentage of values lie above 29?___% (Type an integer or a decimal.)
2.5% of values will lie above 29.
What is normal distribution?
A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.
The 68-95-99.7 rule is an illustration of how those many percentage of values lie in between mean +/- 1, 2, and 3 standard deviations respectively.
For values to lie above 29, their z value comes out to be
(29-19) / 5 = 10/5 = 2
(Note: z value means how many standard deviations above the mean)
Thus for a z value = 2 (which 29 is in this problem) the percentage of values that lie between mean +/- 2*(standard deviation) is 95 (as stated by the 68-95-99.7 rule).
Thus only 5% values wont lie between mean +/-2 standard deviations.
So 5% values wont lie between 29 (z value=2) and 9 (z value=-2).
Since normal curve is symmetric, half of the values of the 5% will lie above 29 and the rest half will lie below 9.
So 50% of 5 % which is 2.5% of values will lie above 29.
Hence, 2.5% of values will lie above 29.

Jackie Revez purchased a new home in Riverside Park. The purchase price was $210,000, and she put down 30%. Her mortgage is 10 1/2% for 30 years. What is the outstanding balance of her loan after the first month? (Round your answer to the nearest cent.)
The formula for simple interest.
SI = P( x R x T) / 100
The outstanding balance of her loan after the first month is $608355
What is simple interest?It is the interest calculated on the principal at a given rate for a time period.
The formula for simple interest.
SI = P( x R x T) / 100
We have,
The purchase price of the home = $210,000
The down payment.
= 30% of 210,000
= 3/10 x 210,000
= 3 x 21,000
= $63,000
Now,
The remaining amount.
= 210,000 - 63,000
= $147,000
Now,
Simple interest for 30 years.
= (147,000 x (21/2) x 30) / 100
= (147,000 x 21 x 30) / 200
= 1470 x 21 x 15
= $463,050
Thus,
The total amount to pay for 30 years.
= 147,000 + 463,050
= $610050
The monthly payment for 30 years.
= 610050 / (30 x 12)
= $1694.58
Now,
The outstanding balance of her loan after the first month.
= 610050 - 1694.58

Write the equation of each line with the given information
Through: (5,3), parallel to y = 1/5x +1
Step-by-step explanation:
you marked the important pieces of information correctly.
a parallel line must have the same slope. otherwise it is tilted differently, and it is therefore not parallel.
the slope in a y = ... equation is always the factor of x.
in our case therefore 1/5.
so, the parallel line starts with
y = (1/5)x + b
and to get b we use the x and y coordinates of the given point :
3 = (1/5)×5 + b = 5/5 + b = 1 + b
b = 2

the standard iq test is designed so that the mean is and the standard deviation is for the population of all adults. we wish to find the sample size necessary to estimate the mean iq score of statistics students. suppose we want to be % confident that our sample mean is within iq points of the true mean. the mean for this population is clearly greater than . the standard deviation for this population is probably less than because it is a group with less variation than a group randomly selected from the general population; therefore, if we use we are being conservative by using a value that will make the sample size at least as large as necessary. assume then that and determine the required sample size.
If we assume that σ = 15 then the required sample size is 216 .
In the question ,
it is given that ,
the standard deviation is (σ) = 15
we want to be 95% confident . So , α [tex]=[/tex] 1 - 0.95 = 0.05
So , [tex]Z_{\frac{\alpha }{2} }[/tex] is = [tex]Z_{\frac{0.05 }{2} }[/tex] = Z₀.₀₂₅
from z table ,
Z₀.₀₂₅ = 1.96 .
e is given to be = 2 IQ points
the sample size (n) is calculated using the formula .
n = (σ × [tex]Z_{\frac{\alpha }{2} }[/tex]/e)²
Substituting the values ,
we get ,
n = (15 * 1.96/2)²
n = (29.4/2)²
n = (14.7)²
n = 216.09
n ≈ 216
Therefore , the sample size necessary to estimate the mean IQ score of statistics students is 216 .

An electronics retailer used regression to find a simple model to predict sales growth in the first quarter of the new year (January through March). The model is good for 90 days, where x is the day. The model can be written as follows:
ŷ = 103.38 + 2.45x
where ŷ is in thousands of dollars.
What would you predict the sales to be on day 60?
Using the regression model you predict the sales to be $ 250.38 on day 60.
What is a regression model?A regression model is an equation used to ascertain the relationship between two variables.
How to find what you would predict the sales to be on day 60?Given that an electronics retailer used regression to find a simple model to predict sales growth in the first quarter of the new year (January through March). The model is good for 90 days, where x is the day.
The model can be written as follows:
ŷ = 103.38 + 2.45x
where ŷ is in thousands of dollars.
Since we require the sales gtowth after 0 days, substituting x = 60 into the equation for the regression model, we have that
ŷ = 103.38 + 2.45x
ŷ = 103.38 + 2.45(60)
ŷ = 103.38 + 2.45(60)
ŷ = 103.38 + 147
ŷ = 250.38
So, you predict the sales to be $ 250.38 on day 60.
