Slope-intercept form is y = mx + b, and m is the slope
Because the slope is -3, m = -3
y = -3x + b
Plug in the point and solve for b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b
a. y = -3x -16
Answer:
k = -19/6
This picture should help you out.
First you distribute -4 among everything in the parenthesis. You will get -4k - 16.
Next you subtract 3 from -16, to get -19.
After that you add 4k to 2k, to get rid of -4k, and you get 6k.
So 6k = -19, and finally you divide 6 on both sides of the equal sign to get k = -19/6.
Hope this helped :)
Answer:
-90
Step-by-step explanation:
Impossible.
The reason is because there is no way you will get a '7' on a die that is marked 1 - 6. There is no 7.
