Answer:
Step-by-step explanation:
<u>The slope of the line that passes through points (0, 0) and (-7, -3) is:</u>
- m = (y₂ - y₁)/(x₂ - x₁)
- m = (-3 - 0)/(-7 - 0) = 3/7
<u>Perpendicular lines have opposite-reciprocal slopes:</u>
Correct choice is C
Answer:
Step-by-step explanation:
t/4+t/3=1
(3t+4t)/12=1
7t/12=1
7t=12
t=12/7
x=(12/7)hours
<h3>

</h3>
Simplify both sides of the inequality.

Subtract 3x from both sides.

t= time taken
s= initial sales
r = rate
Answer:
The swimming pool is 5 times bigger.
Step-by-step explanation:
