What is an equation of the line that passes through the points (-6, -4)(−6,−4) and (3, 8)(3,8)?
Answer:
y = 4/3x + 4
Step-by-step explanation:
-4 - 8 / -6 - 3
-12 / -9
4/3 is slope
y = 4/3 x + b so we need to find b
Put one of the points in for y and x.
-4 = 4/3 (-6) + b
-4 = -8 + b
4 = b
y = 4/3x + 4

Answer:
False
Step-by-step explanation:
Angle S is 6.75
Angle R is 6.8
Angle Q is 10.54
As a result, the answer is False since Angle Q is the greatest among the three angles and Angle S is least.
Suppose that g(x) = f(x) + 5. Which statement best compares the graph of
g(x) with the graph of f(x)?
Answer:
See below
Step-by-step explanation:
Adding 5 to the function means there's a vertical shift of 5. For example, if f(x)=x^2, then g(x)=f(x)+5 makes g(x) 5 units above f(x)

Jeremiah and Cassie went to dinner. Jeremiah’s meal was $25 and Cassie’s was $23. They each got a Pepsi for an additional $3.25. If they planned to leave a 15% tip for their waiter, how much should they leave?
Answer:
8.175$
Step-by-step explanation:
If we do 23+25+(3.25)×2
The sum of all the bought
It will equal to 54.5
So if we do as the waiter planned
We must to 54.5×15%=8.175$
1. The price of one share of a stock fell 4 dollars each day for 8 days. How
much value did one share of the stock lose after 8 days?
2. A credit card company charges a late fee of 25 dollars each time a customer
fails to pay on time. A customer missed the payment 4 times last year. At
the customer's request and out of courtesy, the credit card company
decides to cancel all late fees for that year. Write a numerical expression to
show how much money was return.
Step-by-step explanation:
1.
$4 for 8 days. that means $4 on each and every day, 8 times.
so, in total that is 4 × 8 = $32
that is how multiplications work.
m×n means that m is added n times (or vice versa and n is added m times).
2.
similar here.
$25 each time the customer missed a payment. and he missed 4 times that year.
the bank returned the fees for all 4 occasions. so,
returned money = 25 × 4 = $100

Bret buys a dining table that costs $150 before tax. The sales tax is 8%. How much sales tax did he pay?
Answer:
$12
Step-by-step explanation:
to find sales tax you multiply the cost by the percentage
you do 150 * 8%
thats also 150 * 0.08
150 * 0.08 is 12
so you pay $12 in tax
Bret paid $12 as sales tax.
What is a expression? What is a mathematical equation? What is Equation Modelling? What is denominator?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. In a fraction say (x/y), [y] is called denominator.
We have Bret buys a dining table that costs $150 before tax. The sales tax is 8%.
Assume that he paid $[x] as sales tax. Then, we can write -
[x] = 8% of 150
[x] = (8/100) x 150
[x] = 12
Therefore, Bret paid $12 as sales tax.

Given that T is the centroid of △DEF and FT=12
The centroid of a triangle divides the median of the triangle into 1 : 2
The measure of FQ is 18, while the measure of TQ is 6
Because point T is the centroid, then we have the following ratio
[tex]\mathbf{TQ : FT =1 : 2}[/tex]
Where FT = 12.
Substitute 12 for FT in the above ratio
[tex]\mathbf{TQ : 12 =1 : 2}[/tex]
Express as fraction
[tex]\mathbf{\frac{TQ }{ 12} =\frac{1 }{ 2}}[/tex]
Multiply both sides by 12
[tex]\mathbf{TQ =\frac{1 }{ 2} \times 12}[/tex]
This gives
[tex]\mathbf{TQ =\frac{1 2}{ 2}}[/tex]
Divide 12 by 2
[tex]\mathbf{TQ =6}[/tex]
The measure of FQ is calculated using:
[tex]\mathbf{FQ = FT + TQ}[/tex]
Substitute 12 for FT, and 6 for TQ
[tex]\mathbf{FQ = 12 + 6}[/tex]
Add 12 and 6
[tex]\mathbf{FQ = 18}[/tex]
Hence, the measure of FQ is 18, while the measure of TQ is 6

Find the area of the polygon.
Answer
the area is 26 cm
Step-by-step explanation:
for the first part well call it box C box c is 2 cm by 1 cm the area of that box is 2 because 2 x 1 =2
for box B which is 2 cm by 6 cm because you add the 3 on the bottom to the 3 on the top so box B = 12
for box A it is 3 by 4 so that would be 12
you add the results together 12+12+2=26cm
18x-3y=9 Y=6x-3 what is the answer
Answer:
NP (Not possible)
Step-by-step explanation:
When you find 'X', by inserting '6x-3' into the 'Y', you get:
18x - 3(6x-3) = 9
distribute:
18x -18x + 9 = 9
Subtract 9 from 9 = 0
Add like numbers (the x's), and it equals 0
0=0
You can't find x, rendering the equation 'NP'

Answer:
A. Angle E = 30° and angle D = 60°
Step-by-step explanation:
tan(E) = Opposite/Adjacent
tan(E) = 5/8.66
E = tan^-1(5/8.66)
E = 30°
There's 180° in a triangle, and this is a right triangle.
30 + 90 + x = 180
120 + x = 180
x = 180 - 120
x = 60
D = 60°
Translate to an inequality. Use the variable x.
A number is less than 15.
Answer:
that's the correct answers
Step-by-step explanation:
thanks for your
To translate the statement "A number is less than 15" into an inequality using the variable x, we write:
x < 15
This inequality indicates that the value of x is any number that is smaller than 15. In other words, x can be any real number in the open interval (-∞, 15). It represents a wide range of values from negative infinity up to, but not including, 15.
This statement is not restrictive and allows for infinite possibilities for x, as long as it is smaller than 15. The inequality x < 15 leaves ample room for a wide variety of numerical solutions.
Therefore, to translate the statement "A number is less than 15" into an inequality using the variable x, we write:
x < 15

Kianna's and Jo's houses are reflections of each other across both axes.
1. What are the coordinates of Jo's house? Explain how you know in the space below.
2. Kianna walks from her house to Jo's house. She first walks west and then walks south. How many blocks west does Kianna walk? How many blocks south?

What are the coordinates of Elena's house? Explain in the space below.
4. Kianna says that Elena's house is actually a reflection of her house across the y-axis.
Is Kianna right? Explain
Answer:1. The coordinates of Jo’s house are (-4,-2).
Step-by-step explanation:
1. Since Jo’s house is reflected across both axes, we must reflect the coordinates two times. So we can reflect the coordinates of Kianna’s house across the x-axis first, which would give you the coordinates (4,-2). Then we reflect (4,-2) across the y axis, giving us the coordinates (-4,-2). So Jo’s house has the coordinates (-4,-2).

Helena asked five drama club members in her homeroom how many tickets they had sold. The mean number of tickets sold was 16. Then she took ten random samples from the entire drama club of 75 students. The mean number of tickets sold was 22. 5. Compare the means. Is one sample a better representation? Explain why or why not.
The total sum of the population in the first sample is greater than the second, hence the first sample is a better representation.
The formula for calculating the mean of numbers is expressed according to to the formula;
[tex]\overline x=\frac{\sum x}{n} \\[/tex]
n is the total sample space
[tex]\overline x[/tex] is the mean of the samples
[tex]\sum x[/tex] is the sum of the variables
If the mean number of tickets sold by five drama club members was 16, then;
[tex]16=\frac{\sum x}5}\\\sum x = 16 \times 5\\\sum x_1 = 80[/tex]
If she took ten random samples from the entire drama club of 75 students with a mean number of 22.5, hence;
[tex]\sum x_2 = 75[/tex]
Since the total sum of the population in the first sample is greater than the second, hence the first sample is a better representation.
