The domain are the x values: 0,1,2
The range are the y values: 4,5,6,7,8
Answer:
x = 19
Step-by-step explanation:
1. add 31 on both sides (you wanna get the "x" by itself)
ex: 2x - 31 = 7
+31 +31
2. the 31s cancel each other out so now you add 31 + 7
2x = 7
+31
___________
38
3. divide 2 on both sides so the 2s cancel each other out and only the x is left
ex: 2x / 2 = x 38 ( the 38 stands alone)
4. now divide 38/2 and you have your answer
X= 19
Answer:
not me
Step-by-step explanation:
The y intercept of that rule is 0
(2,8) and (-2,10)
<u>y₂</u><u> </u><u>- y₁</u> used to find the slope<u>
</u>x₂ - x₁
<u>
</u>plug in the coordinates
<u>10-8</u> = <u>2</u> all equals -1/2
-2-2 = -4 m=-1/2
<u>
</u>plug one of the coordinates and the slope into y=mx+b, and solve
<u />8=-1/2(2)+b
8=-1+b
9=b
Final Answer: y = -1/2x + 9
