Answer:
y = 1/2x - 7
Step-by-step explanation:
slope intercept form:
y = mx + b
y = -5
m(slope) = 1/2
x = 4
y = mx + b
<em>substitute </em>
-5 = 1/2*4 + b
-5 = 2 + b
-5 - 2 = b
-7 = b
y = 1/2x - 7

Just because the fish swam away doesn't mean they left the pond
Answer:
Step-by-step explanation:
<u>Given expression</u>
<u>Solving for x</u>
- 4px + 4 = 64
- 4px = 60
- px = 15
- x = 15/p
<u>Value of x when p= - 5</u>
Answer:
Let's suppose that one cubic foot of marble is x.
20x = 3400
But because the weight has a range of +-100, then 20x is between 3300 and 3500. Write it like this:
3300<20x<3500
Divide by 20:
165<x<175
The meaning of this is that one cubic foot of marble weight between 165 and 175 pounds
