$5*4 = $20
Answer:
x = 12
Step-by-step explanation:
9x + 7 and 115 are alternate exterior angles and are congruent, then
9x + 7 = 115 ( subtract 7 from both sides )
9x = 108 ( divide both sides by 9 )
x = 12
Answer:
20 minutes
Step-by-step explanation:
40% = 8 minutes
40% x 2.5 = 100%
8 minutes x 2.5 = 20 minutes
The center of the circle is (7,8) and the equation of the given circle is (x- 7)^2 + (y - 8)^2 = 16
<h3>How to determine the equation of the circle?</h3>
The given parameters are:
Center (a,b) = (7,8)
Point (x,y) = (11,8)
Calculate the radius (r) using:
So, we have:
Evaluate the expression
The circle equation is then calculated using:
So, we have:
Evaluate the exponent
Hence, the equation of the given circle is (x- 7)^2 + (y - 8)^2 = 16

Select two points and use the Slope Formula to find slope, or m.
4 - 6 / -1 + 2 = -2/1 = -2
We now have this.
y = -2x + b
Select one of the coordinate points and input it into the equation to find b.
2 = -2(0) + b
2 = b
y = -2x + 2
