7y + 13 - 4z
We have y=5 and z =9.
Everything you need to do is replace y by it's value, and z by it's value, and calculate following the orders of operations.
7*5 + 13 - 4*9
First, you calculate the multiplications, then you subtract and add.
35 + 13 - 36 = -1 + 13 = 12

Hope this Helps! :)

What is the point-slope equation of a line with slope -5 that contains the point (6,3)
Luden [163]

Answer:

y-3=-5(x-6)

Step-by-step explanation:

we know that

The equation of the line into point-slope form is equal to

y-y1=m(x-x1)

we have

m=-5

(x1,y1)=(6,3)

substitute

y-3=-5(x-6) ----> equation of the line into point-slope form
