30 * 25 = 750
750/60 = 12.5
x = 12 hours and 30 minutes
Answer:
1:13
Step-by-step explanation:
Answer:
A. y = -5/4x + 3
Step-by-step explanation:
Step 1: Find coordinates
(0, 3)
(4, -2)
Step 2: Find slope
m = (-2 - 3)/(4 - 0)
m = -5/4
y = -5/4x + b
Step 3: Rewrite equation (we already found y-int)
y = -5/4x + 3
Answer: y = (-2/5)x - 7
This is the same as writing 
======================================================
Explanation:
Any linear equation is of the form y = mx+b, known as slope-intercept form
m = slope
b = y intercept
We'll replace m with -2/5 and replace b with -7 to get y = (-2/5)x + (-7) which simplifies to y = (-2/5)x - 7
