Answer:
Step-by-step explanation:
8x+9/x^2-13x+42
Write 8
x as a fraction with denominator 1
8x+9/x^2-13x+42
then we multipuly 8x/1 by x^2/x^2
Answer: 5 feet and 7 inches
Step-by-step explanation:
"Give yourself 100 pounds for the first 5 feet plus 5 pounds for every inch over 5 feet tall"
100 pounds for 5 feet + 5 pounds/inch [over 5 feet]
We can separate 135 pounds into two parts: the first 100 pounds and the other 35 pounds: 135 = 100 + 35
100 = 5 feet
35 pounds/5 pounds/inch = 7 inches
So, the height is 5 feet and 7 inches

Answer:
(x - 3)^2 + (y + 1) = 25
Step-by-step explanation:
First find the midpoint of the diameter, because that represents the center of the circle.
-1 + 7
The x-coordinate of the midpoint is xm = ---------- = 3
2
2 - 4
and the y-coordinate is ym = ---------- = -1
2
And so the center of this circle is at (3, -1).
Use the Pythagorean Theorem to determine the square of the radius:
square of radius = 4^2 + (-3)^2 = 16 + 9 = 25
And so the equation of this circle is (x - 3)^2 + (y + 1) = 25
