Answer: y=-3x-16
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is slope and b is y-intercept.
y-2=-3(x+6) [distribute]
y-2=-3x-18 [add both sides by 2]
y=-3x-16
Now, we see that the equation above matches the slope-intercept form equation. You can see that m=-3 and b=-16.

(a) (sin A + sin B) (sin A-sin B)
Answer:
Sin^2A-sin^2B
Step-by-step explanation:
(sin A + sin B) (sin A-sin B)
=SinA(sinA-sinB)+SinB(sinA-sinB)
=Sin^2A-sinAsinB+sinBSinA-sin^2B
=Sin^2A-sin^2B
Vertical Motion A football is released into the air at an initial height of 6 feet and an initial velocity of 30 feet per second. The football is caught at a height of 7 feet. Use the vertical motion model h=-16t^2+vt+s where h is the height, t is the time in motion, s is the initial height, and v is the initial velocity, to find how long the football is in motion.
Answer:
16^6t^2+30^6+15

Ali is cutting a pizza into serving sized sections he uses a long knife to be sure that the cuts he makes in the pizza are straight which statements are true select all that apply
Answer:
1. Ali makes three straight long cuts along the diameter of the pizza.
2. Ali makes two straight long cuts along the diameter of the pizza.
Step-by-step explanation:
Each serving size in a pizza contains consistent weight but the fraction of the pie can change depending upon the size of the pizza., size of crust, toppings, etc.
The pizza can be cut into different pie section depending upon the size of the pizza. One-sixth or one-fifth is the most common pie sections.
Ali uses a long knife to cut the pizza in a straight line. He must cut the pizza in to 8 pieces or 4 pieces so that he can be sure that the pizzas are cut in a straight line.
For 8 pieces of pizza, Ali has to make three straight long cuts across three diameters of the pizza and for 4 pieces, Ali has to make two straight long cut along the diameters.

An adult female gorilla is 1.4 meters tall when standing upright. Her daughter is 3 tenths as tall. How much more will the young female gorilla need to grow before she is as tall as her mother?
Answer:
0.98 meters
Step-by-step explanation:
Since she is three-tenths as tall as her mother, she is 0.42 meters tall (1.4 × 0.3 = 0.42). That means she has to grow 0.98 meters to be 1.4 meters tall.
A data set has a median of 12, an upper quartile of 15, a lower quartile of 10, a minimum of 4, and a maximum of 20. Which statement is true of the box plot of this data set? The box will go from 10 to 12. A line dividing the box will be at 12. The left whisker will go from 4 to 15. The right whisker will go from 12 to 20.
Given:
A data set has a median of 12, an upper quartile of 15, a lower quartile of 10, a minimum of 4, and a maximum of 20.
To find:
The correct statement for the box plot.
Solution:
Lower quartile is 10 and upper quartile is 15, so the box will go from 10 to 15.
Median of the data set is 12, so a line dividing the box will be at 12.
Minimum value is 4 and lower quartile is 10, so the left whisker will go from 4 to 10.
Upper quartile is 15 and maximum value is 20, so the right whisker will go from 15 to 20.
Therefore, the correct option is B.
Answer:
its b

Convert 122lbs to Kilograms and plz show how you got the answer!!!!!!
Answer:
55.83
Step-by-step explanation:
Divide the number of pounds by 2.2046 to use the standard equation.
Answer:
55.34 kg
Step-by-step explanation:
1 kg = 2.204 lbs
then
[tex]122 lbs\times \frac{1 \: kg}{2.204 \: lbs} [/tex]
because lbs from the numerator will goes with lbs in the denominator the only unit remains is kg
so
122 ÷ 2.204 kg = 55.34 kg
which set of points below lie on a line that is parallel to AB?
a=(-4,5) and (6,-2)
b=(-5,4) and (5,-2)
c=(1,0) and (5,2)
d=(-3,-4) and (0,1)
Answer:
The answer is (1,0) and (5,2)
Step-by-step explanation:
Since they are asking for parallel lines that means the slopes of the lines has to be the same line AB slope is 1/2 if you find the slope of (1,0) and (5,2) it will be the same as 1/2

2/3x−1/5x=x−1
Answer:
x=15/8
Step-by-step explanation:
Given: 2/3x-1/5x=x-1
Determine LCD: 10/15x-3/15x=x-1
Combine like terms: 7/15x=x-1
Get x on one side only: -8/15x=-1
Divide the coefficient on both sides: x=15/8

Answer:
8. 95°
9. 85°
10. 49°
11. 53°
Step-by-step explanation:
8) m + 28° + 57° = 180°
m = 180°–28°–57°
m = 95°
9) m∆4 + m∆5 = 180°
95° + m∆5=180°
m∆5 = 180°–95°
m∆5 = 85°
10) 180°–36°–95°=49°
11) 180°–42°–85°=53°
Vincent purchased a scooter for $124 before tax. The store adds a 7.8% sales tax to every purchase. How much did Vincent pay for the scooter, to the nearest penny?
Step-by-step explanation:
Original price of the scooter = $124
Sales Tax = 7.8%
Price of the scooter after tax = 124 + 7.8%(124)
= 124 + 7.8/100 x 124
= 124 + 3.9/50 x 124
= 124 + 1.95/25 x 124
= 124 + 0.39/5 x 124
= 124 + 0.39 x 24.8
= 124 + 9.672
= 133.672
Therefore, after tax the scooter will cost $133.672.
There are several bowls containing various amounts of grapes on a table. When 12 of the bowls each had 8 more grapes added to them, the mean (average) number of grapes per bowl increased by 6. How many bowls of grapes are on the table?
Answer:
There are 16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
OR
12 x 8 = 96
96/6=16
Answer:
16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
