C. x^21*y^-21
Step-by-step explanation:
When it's set up like this, you have to multiply the exponents. -3*-7=21, and 3*-7=-21. Thus, the only option for this equation is going to be C.

Trish is ordering t-shirts from a website that charges a certain amount per t-shirt plus a flat rate for shipping. The cost for a given number of t-shirts is shown in the table.
20a. Write an equation to represent the situation. (Write your answer with no spaces, all lowercase letters, and write the slope as a decimal)
20b. What does the slope mean in the context of the situation?
20c. What does the y-intercept mean in the context of the situation?
Answers
Answer:
Hope this helps
Step-by-step explanation:
T means amount of t shirts they are buying
5.99 is amount of shipping cost
first do 32.24-5.99=26.25
then do 26.25/3=8.75
so 8.75= cost of shirt
20a. (8.75*T)+5.99
20b.(I might get this part wrong just let me know)
M=Y2-Y1/X2-X1
so 32.24-5.99/3-0= 26.25/3 Or 8.75
20c=Y=Mx+B
3=8.75(32.24)+b=-279.1

One part is that it says that she makes more than, not more than or equal too 150. Which cuts the options down to two.
A. and C.
The second thing that the text says is that she makes 9 dollars and hour, not 75 an hour. Which means that A. can't be the answer.

you subtract 80 from 180 to get the sum of y and 60, which is 100. because y doesn’t include the 60 degrees, you subtract 60 from 100.
then, you get 40 for y. because x is a vertical angle of y, you get 40 for x as well since they’re congruent to each other.
Answer:
40°
Step-by-step explanation:
So a straight line is 180°...
(Supplementary angle) You have 80+60=140
180-140=40°
Y= 40°
Y is equal to x since it is the alternative angle

Answers
Answer:
57.74 yd²
Step-by-step explanation:
First, find the area of the "rectangle" as if there weren't different figure cut out of it:
(5+6+5)8
16(8)
128 yd²
Next, we are going to find the area of the four figures that are cut out from the rectangle. The circle at the bottom, the rectangle at the top, and the triangles on each side.
The first shape we can tackle will be the circle. The formula for finding the area of a circle is πr² or in this case 3.14r². The diameter of the circle is 6 yards, and half of the diameter is equal to the radius which gives us 3 yards as the length. Now simplify the expression:
3.14(3)²
3.14(9)
28.26 yd² is the area of the circle.
Next, we're going to find the area of the rectangle at the top. It's dimensions are 6 yards by 3 yards, which gives us an easy 18 yards² as the area (lxw).
Now we're going to solve for the area of the triangles. By the looks of the general dimensions of this shape, I am assuming these triangles are congruent to each other, which means we will only have to solve for its area once. To find the area of a triangle we have to use the expression: (lxw)/2. However, we don't know one of those dimensions. We know that the length is 8 yards as shown in the diagram, and by using the widths 2 yards and 5 yards, and their relation to the triangle, we can deduce the width is 3 yards. Now we have values necessary to simplify the expression:
(8x3)/2
24/2
12 yards² is the area of one triangle.
Because I stated previously that the triangles are congruent, they both have an area of 12 yards. Now we add the areas of each of the four figures, and subtract them from the area of our large rectangle:
128-(12+12+28.26+18)
128-70.26
57.74 yd² is the area of the shaded region

The sum of the three interior angles of a triangle is 180 degrees.
A- 3 a = 180°
B- a + 55° + 36° = 180°
C- x + y + z = 180°
D- x3 = 180°
E- x · y · z = 180°
Answers
Answer:
A) 3a = 180°
B) a+ 55° + 36° = 180°
C) x + y + z = 180°
Step-by-step explanation:
The answer is the A option since all the side of the triangle could be the same, making it an equilateral triangle. ( 60° + 60° + 60° = 180° )
The sum means that all the angles are added, not necessarily being similar terms, which equals to 180°.
The terms don't have to be similar, for instance the B option,
a+ 55° + 36° = 180°
since you could find the value of a.
The same thing goes for C.
(Extra)
It is not D since x is multiplied with 3, not giving the sum.
It is not E since all the 3 terms are multiplied, not giving the sum.
Your investment of $18,100 at 13.6% compounded annually for 7.5 years will be worth how much?
Answers
Explanation
The amount will be worth $47099.47 after investment of $18,100 at 13.6% compounded annually for 7.5 years.
What is compound interest?Interest accrued on both the principal sum of money and the interest already earned.
The formula for compound interest is
A= p(1+r/100)ⁿ
Where p is principal, r is rate and n is time.
Given that,
The principal amount of investment = $18,100,
Rate of interest = 13.6% compounded annually,
Time = 7.5 years.
The amount after 7.5 years
= [tex]18,100(1 + 13.6/100 )^{15/2}[/tex]
= 47099.47
The amount after 7.5 years will be worth $47099.47.

M = (3, 9)
N = (6, 0)
O = (3, 6)
P = (-3, 0)
All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.
M = (3, 9) = (3*1/3, 9*1/3) = (1, 3)
N = (6, 0) = (6*1/3, 0*1/3) = (2, 0)
O = (3, 6) = (3*1/3, 6*1/3) = (1, 2)
P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)
(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.
