Answer:
I think it's -5x
Step-by-step explanation:
I'm assuming the zero pair is simply adding
11 • 18 = 198. Mrs. Gannon should need 198 pine cones
Answer:
B
Step-by-step explanation:
let y = 5x - 3
rearrange making x the subject
add 3 to both sides
5x = y + 3 ( divide both sides by 5 )
x = 
change y back into terms of x, hence
(x) =
→ B
Answer:
x=71
Step-by-step explanation:
38+x+x=180
x+x=142
2x=142
x=71
Answer:
(1/2, 0), (0, -2)
Step-by-step explanation:
We can determine the slope from ...
slope = (change in y)/(change in x) = (10 -2)/(3 -1) = 8/2 = 4
Then an equation for the line can be written for slope m and point (h, k) as ...
m(x -h) -(y -k) = 0
Using the slope we calculated and the first point, we have the equation ...
4(x -1) -(y -2) = 0
4x -4 -y +2 = 0 . . . . . eliminate parentheses
4x -y = 2 . . . . . . . . . . put in standard form
Now, we can divide by the constant on the right to put this into intercept form:
x/(x-intercept) + y/(y-intercept) = 1
x/(1/2) + y/(-2) = 1
The x-intercept is 1/2; the y-intercept is -2.
