Y= mx +b
Y= 2x -5
You have to find what is x
After 10 minutes, he's 40 miles away. After 22 minute, he's 34 miles away. Therefore, in those 12 minutes between, he covered 6 miles. We can make a ratio out of this: 6/12 = 0.5, so he is walking at a rate of 0.5 mi/min (miles per minute). Finally, we can set x/90 equal to 0.5/1 because he is walking at the same rate the entire time. Cross multiply to solve for x. Finally, you get that he had to travel 45 miles in 90 minutes, so his home is 45 miles away from his grandmother's.
Answer:
y = 1/4x +7
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 1/4 x +b
Substitute the point into the equation
8 = 1/4(4) +b
8 = 1 +b
Subtract 1 from each side
8-1 =b
7 =b
y = 1/4x +7
Answer:
1. 50 is 20% of 250
Step-by-step explanation:
In order to find any of these, use the equation.
Number/Out of = %
Then plug in the values
50/x = .20
Then solve by cross multiplying
50 = .20x
250 = x
Step-by-step explanation:
Commission earned
= 1/32 * Total sales
= 1/32 * $24,000
= $750.
