Answer:
1 and 11/16 miles
Step-by-step explanation:
running around once is 3/8 miles, 4 1/2 is the same as 9/2
9/2 * 3/8 = (9*3)/(2*8) = 27/16, or 1 and 11/16
The slope for that is again, change in y over change in x.
(6-4)/(4-3) = 2/1
The slope would be 2
Answer:
The value of a is 3
Step-by-step explanation:
First you have to make an equation based on the point and slope that you were given. The formula for this is y-(y cordinate of point)=slope(x-x cordinate of slope)
y--2=-3(x-6), which simplifies to y+2=-3(x-6)
In (a,7), 7 is the y coordinate. We have to plug 7 in for the y in our equation.
7+2=-3(x-6),
Combine like terms on the left side to get to 9=-3(x-6)
Multiply out on the left to get 9=-3x+18
Subtract 18 from the left side to get -9=-3x
Divide both sides by negative 3 to get 3=x (remember x is a)
