Answer:
after 1.25 hours
Step-by-step explanation:
1. make 130 your y value
130 = 220 - 72x
2. subtract 220 from both sides
-90 = -72x
3. divide by -72 on both sides
1.25 = x
Answer:
x = 7
Step-by-step explanation:
The point-slope equation of the line is ...
y -(-13) = -3(x -3)
Substituting -25 for y, we can solve for x:
-25 +13 = -3x +9
-21 = -3x . . . . add -9
7 = x . . . . . . . divide by -3
Answer:
y = -3
Step-by-step explanation:
This is because horizontal lines have a slope of 0. And for horizontal lines, the equation of the line is y = b. So, b is the y-intercept and the y intercept is -3 so that is the equation of the line.
Answer:
The other number is 60.
Step-by-step explanation:
2400 divided by 40=60
60 times 40=2400
