Kindly check explanation
Step-by-step explanation:
Given that :
Objective is to compete in a 5km road race ;
Reduction in race tone per month = 15 seconds
Rqce comes up in 3 months
Total change in race time he hopes to achieve :
1. What integer represents the change in race time Riley wants to achieve each month ; 15 seconds
2. What integer represents the number of months she will train?
She will train for 3 months ; 3 months
Write a multiplication expression that can be used to find the total change in time.
Change in race time * number of month she will train
15 seconds * 3 months = 45 seconds
Let initial race time = (t)
t - 15(month in which race comes up).
t - (15-3) = t - 45
Answer:
x=8/3f
Step-by-step explanation:
Answer:
y=5/3x-3
Step-by-step explanation:
first, let's put 3x+5y=15 into y=mx+b form
move 3x to the other side
5y=-3x+15
divide by 5
y=-3/5x+3
now, perendicular lines have slopes that are negative and reciprocal.
With our new equation we can automatically find the slope, which would be 5/3.
now, we need to find b
plug the points (3,2) into y=5/3x+b
2=5/3(3)+b
2=5+b
-3=b
so that means that our equation will now be
y=5/3x-3.
Hope this helps!
