Answer:
y = 5x-5
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( 10-5)/(3-2)
= 5/1
=5
Using slope intercept form
y = mx+b
y = 5x+b
Substituting a point into the equation
5 = 5*2+b
5 = 10+b
Solving for b
5-10 = b
-5 =b
y = 5x-5
Answer:
D. 9p + $11.50 = $94.75; p = $9.25
Step-by-step explanation:
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter D.

Let
p---------> the price of each scrub
s----------> the price of the potting soil
T--------> total bill
we know that
in this problem
substitute the values in the formula above
solve for p
therefore
the answer is the option D

Answer:
Step-by-step explanation:
2(5)(-5)-(5)^2
=−75
Subtract 8/15 from both sides so you get x= -0.36
