Answer:
It's incorrect because the equation is solve incorrectly the anwer is r= -4
Step-by-step explanation:
Add 4r4r to both sides.
-3r+9+4r=5
−3r+9+4r=5
2 Simplify -3r+9+4r−3r+9+4r to r+9r+9.
r+9=5
r+9=5
3 Subtract 99 from both sides.
r=5-9
r=5−9
4 Simplify 5-95−9 to -4−4.
r=-4
r=−4

Classify each pair of angles as complementary, supplementary, or neither.
Drag and drop the choices into the boxes to correctly complete the table. Each pair of angles may belong to more than one category.
complementary supplementary neither
Answers
Answer:
neither; neither; supplementary
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
First picture: 32° + 48° = 80°
80° < 90° and 80° < 180°
Therefore they are neither
Second picture: 101° + 77° = 178°
178° > 90° and 178° < 180°
Therefore they are neither
Third picture: 107° + 73° = 180°
180° < 90° but 180° = 180°
Therefore they are supplementary
neither neither and supplementery cus i smrt

Answers
Answer:
y=-2x-4
Step-by-step explanation:
The slope has a Y-intercept at the -4, which narrows the choices down to 2. Since the slope is leaning left, it's a negative, which will make the answer to this y=-2x-4

Joe ordered an 18 inch pizza with pineapple and ham on it from Mr. T's Famous Chicago Style Pizzeria. The pizza was cut into 6 slices. Joe ate only two slices and decided he didn't like the famous pizza and discarded the rest. How many square inches of pizza did he throw away? Use 3.14 for pi. Round to the nearest tenth of a square inch.
Answers
Answer:
[tex]A_4 = 170\ in^2[/tex]
Step-by-step explanation:
Given
[tex]Diameter = 18\ in[/tex]
[tex]Slices = 6[/tex]
[tex]Eaten = 2[/tex]
Required
Determine the area of the discarded part
First, calculate the area of the pizza.
[tex]Area = \frac{\pi D^2}{4}[/tex]
Substitute 18 for D and 3.14 for [tex]\pi[/tex]
[tex]Area = \frac{3.14 *18^2}{4}[/tex]
[tex]Area = \frac{1017.36}{4}[/tex]
[tex]Area = 254.34[/tex]
If he eats 2 out of the 6 slices, then it means he discarded 4 out of the 6.
So, the area of the 4 is:
[tex]A_4 =\frac{4}{6} * Area[/tex]
[tex]A_4 =\frac{4}{6} * 254.34[/tex]
[tex]A_4 =\frac{4* 254.34}{6}[/tex]
[tex]A_4 =\frac{1017.36}{6}[/tex]
[tex]A_4 =169.56in^2[/tex]
[tex]A_4 = 170\ in^2[/tex] -- approximated
The area of the discarded is 170 square inches

Ann receives a 4% commission on her sales. Her last paycheck included $196 in commissions. Solve the formula C = 0.04s for s, where C is the amount of commission and s is the amount of sales. Then substitute to find her sales.
A.
$195.96
B.
$196.04
C.
$7.84
D.
$4,900
Answers
Answer:
D-$4,900
Step-by-step explanation:
Answer:
The answer is D. $4,900
Step-by-step explanation:
$196 in commissions => a = 196
s = a / 0.04 = 196 / 0.04 = $4900 = Ann's sales
so the answer for Ann's sales is $4,900

What type of solutions to quadratic equations can be solved by factoring and using the zero product property?
Answers
Answer:
The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.
