Answer:
51.8
Step-by-step explanation:
Multiply 15 by z and -51 which would equal (15z-765).
Add 765 to 12 and that equals 777
Divide 777 by 15 which would equal 51.8

Answer:

13 glue sticks cost $25.22.
Step-by-step explanation:
4 blue sticks cost $7.76, this means that one glue stick costs
$7.76/4 = $1.94.
Let
be the cost of the glue sticks, and
be the number of glue sticks; then

We can use this equation to find the cost of 13 glue sticks; we just put
into our equation and it gives:

So 13 glue sticks cost $25.22.
When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.
Then when you look at the second one, it goes right one and up four.
As rise over run, it would be 4 / 1 or simply 4.
The slope is 4 and the y-intercept is -2
Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.
y = 4x -2
Answer:
10x+y
