X=10 and x=0
Steps:
5x=x^2/2
10x=x^2
x^2-(10x)=0
(x-10)(x+0)=0
Solve for factors
x-10=0
x=10
x+0=0
x=0
Answer:
y-11=1/23(x-2)
Step-by-step explanation:
Perpendicular slope is 1/23 you just plug in the points! :)
Solve the first for y
y=13x-90 and the second is y=x^2-x-42
When there is/are solutions y=y so we can say:
x^2-x-42=13x-90 subtract 13x from both sides
x^2-14x-42=-90 add 90 to both sides
x^2-14x+48=0 expand so that it is easy to factor...
x^2-6x-8x+48=0 now factor 1st and 2nd pair of terms
x(x-6)-8(x-6)=0
(x-8)(x-6)=0
So there are two solutions, when x=6 and 8.
Using either original equation we can find the corresponding values for y. I'll use y=13x-90 because it is easier...
y(6)=-12, y(8)=14 so the two solutions are the points:
(6,-12) and (8,14)
Answer:
79.38 miles per hour
Step-by-step explanation:
average speed = miles covered / hours
= 515.97 / 6.5
= 79.38
25/18 is already in its most simplified improper fraction form because there are no common factors between the numerator and denominator besides 1.
As a mixed number it would be 1 and 7/18.
