Ax+b=y
put the both values the left one is x and the right one is y
(1,3)=> a+b=3
(2,1)=> 2a+b=1
subtract both of the equations you will get -a=2
so a=-2 and put a in any of the equation you will get b is 5 so the equation is -2x+5=y
the slope is the x’s number so it’s -2
Answer:
A
Step-by-step explanation:
You don't know whether they're all 90 degrees because we don't know about AB and CD.
If you would like to solve the equation y/9 + 5 = 0, you can do this using the following steps:
y/9 + 5 = 0
y/9 = -5 /*9
y = -5 * 9
y = - 45
The correct result would be D. y = - 45.
If you would like to solve - 282 - (+ 1,017), you can do this using the following steps:
- 282 - (+ 1,017) = - 282 - 1,017 = - 1,299
The correct result would be C. - 1,299.
Answer: (I'm assuming the "?" is a typo?)
Step-by-step explanation:
Don't forget we can't add two different variables together (ex. we can't add together because they're different variables).
A. your equation would be 17 + 8.50X
number of additional large pizzas equation cost
1 17 + 8.50(1) $25.50
2 17 + 8.50(2) $34.00
3 17 + 8.50(3) $42.50
b. will get back to you
c. 17 + 8.50 (20) = 187 $187
d. $34 X 5 = $170 17 + 8.50 (14) = $136 170 - 136 = $34 saved
