So all you have to do to solve these problems is substitute the y coordinate and the x coordinate into the equation.
So question 1 would be true because when you substitute the numbers in it equals the y value.
Question 2 is (4, -7)
Question 3 is False
Question 4 is true
Question 5 is true
See if you can do the rest!
Answer:
There are 80 paperbacks on the shelf
Step-by-step explanation:
Multiply 2/3 by 120
So that would be:
2/3 x 120/1
(2 x 120)/(3x1)=240/3=80
Answer:
<em>x = -10</em>
Step-by-step explanation:
(9/2)(8 - x) + 36 = 102 - (5/2)(3x + 24)
Multiply both sides by 2.
9(8 - x) + 2 * 36 = 2 * 102 - 5(3x + 24)
Distribute on both sides.
72 - 9x + 72 = 204 - 15x - 120
Combine like terms on each side.
144 - 9x = 84 - 15x
Subtract 144 from both sides. Add 15x to both sides.
6x = -60
Divide both sides by 6.
x = -10
Answer:
C. 31
Step-by-step explanation:
3000 there are 3-4 errors
If we first divide 24,000 by 3,000, will get 8
then since there a error for each 3,000 books, we do 8 x 4 = 32 and 8 x 3 = 24
32 (8 x 4) the max amount of printing errors
24 (8 x 3) the minimum amount of printing errors
So we should expect 24-32 printing errors
Only answer between the numbers is c. 31
Step-by-step explanation:
by using linear pair
62+x=180
x=180-62=118
