Answer:
x = 4
Step-by-step explanation:
First we will subtract 7 from 11 to get
-x = 4 - 2x, next we will add 2x to -x to get
x = 4.
(It's just a matter of combining like terms.)

work out the m and c for the line 3y+2x=-1
Answer:
m = -2/3 and b = -1/3
Step-by-step explanation:
Write the equation of this line in slope-intercept form. Then m = slope and b = y-intercept and the basic equation is y = mx + b.
Solving 3y+2x=-1 for y, we get 3y = -2x - 1, or y = (-2/3)x - 1/3
Here we can easily see that m = -2/3 and b = -1/3.

Solve the following quadratic function by utilizing the square root method. y = x2 - 64
Answer:
[tex]x=\pm\sqrt{y+64}[/tex]
Step-by-step explanation:
All you need to do is isolate the x.
First, add 64 to both sides:
[tex]y=x^2-64\\x^2-64+64=y+64\\x^2=y+64[/tex]
Then, take the square root of both sides:
[tex]\sqrt{x^2}=\sqrt{y+64}\\x=\sqrt{y+64[/tex]
Actually, that is:
[tex]x=\pm\sqrt{y+64}[/tex]
Here's the reason for that. An example would be:
[tex]x^2=4[/tex]
Here, you'd take the square root of both sides to solve for x.
[tex]\sqrt{x^2}=\sqrt{4}\\x=2[/tex]
Right? But X could also be a -2, because a negative times a negative is a positive.
[tex](-2)^2=4\\-2\times-2=4\\4=4[/tex]
Therefore, [tex]x=2, -2[/tex] or [tex]x=\pm2[/tex]
[tex]x^2=2\times2=4\\x^2=-2\times-2=4[/tex]
The ratio of students in Class X to Class Y is 2 : 5. There are 24 more students in Class Y than Class X. How many students must transfer from Class Y to Class X so that both classes have equal number of students?
Answer: 12 students
Step-by-step explanation:
Let X and Y stand for the number of students in each respective class.
We know:
X/Y = 2/5, and
Y = X+24
We want to find the number of students, x, that when transferred from Y to X, will make the classes equal in size. We can express this as:
(Y-x)/(X+x) = 1
---
We can rearrange X/Y = 2/5 to:
X = 2Y/5
The use this value of X in the second equation:
Y = X+24
Y =2Y/5+24
5Y = 2Y + 120
3Y = 120
Y = 40
Since Y = X+24
40 = X + 24
X = 16
--
Now we want x, the number of students transferring from Class Y to Class X, to be a value such that X = Y:
(Y-x)=(X+x)
(40-x)=(16+x)
24 = 2x
x = 12
12 students must transfer to the more difficult, very early morning, class.

Jayden’s rectangular garden is 5 3/4 feet long and 4 1/2 feet wide. What is the area, in square feet, of the garden
Answer:
The area is 25.875 square feet. Or it can be written as [tex]25\frac{7}{8}[/tex]
Step-by-step explanation:
You would simply multiply them by each other. 5 3/4 is aso 5.75. And 4 1/2 is also 4.5. So simply multiply 5.75 by 4.5
5.75*4.5 to get 25.875
The interval (-1, 1) is best described as
Answer: There's an increasing interval between -1 and 1
While x goes from -1 to 1, the value of y increases (from -2 to 2).
which is bigger 11/18 or 5/14
Among the fractions given in this question 11/18 and 5/14, the largest fraction is: 3/5.
Step-by-step explanation:To find out which fraction is the largest, just divide the numerator by the denominator of the ratio and make the comparisons between them, thus defining which is the largest by decimal places or the largest number.
Resolution:[tex]\large \sf \dfrac{11}{18} \rightarrow 11\div18\rightarrow 0{,}61111111111[/tex]
[tex]\large \sf \dfrac{5}{14} \rightarrow 5\div14\rightarrow 0{,}35714285714[/tex]
Conclusion:We can conclude that the largest fraction, being between 11/18 and 5/14, is 11/18.
A retirement account was opened with a $900 deposit. If the account earns 4.25% interest compounded continuously and has no other deposits or withdrawals, how long will it take the value to double?
It will take 16.66years long for the money to double
The formula for calculating the compound amount is expressed as:
A = P(1+r)^t
A is the amount after t years = 2(900) = $1800P is the amount invested = $900r is the rate in decimal = 4.25% = 0.0425Substitute into the formula to have:
1800 = 900(1+0.0425)^t
2 =(1+0.0425)^t
2 = 1.0425^t
ln2 = tln1.0425
t = ln2/ln1.0425
t = 0.6931/0.0416
t = 16.66years
This shows that it will take 16.66years long for the money to double

There are only red sweets and yellow sweets in a bag.

He says that the probability that the sweet will be red is
10
7
10
(a) Show why the probability cannot be
Using the probability concept, it is found that since the number of red sweets would be a decimal number, the probability cannot be [tex]\frac{7}{10}[/tex]
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem:
In total, there are 8 + n sweets in the bag.Of those, n are red.The probability of red is:
[tex]p = \frac{n}{n + 8}[/tex]
Supposing [tex]p = \frac{7}{10}[/tex], we solve for n:
[tex]\frac{n}{n + 8} = \frac{7}{10}[/tex]
[tex]10n = 7n + 56[/tex]
[tex]3n = 56[/tex]
[tex]n = \frac{56}{3}[/tex]
[tex]n = 18.67[/tex]
Since the number of red sweets would be a decimal number, the probability cannot be [tex]\frac{7}{10}[/tex]
