Answer:

x^2 + y^2 +16x - 24y +159 = 0

Rearrange:

x^2 +16x + y^2 - 24y = -159

(16x/2)^2 = 64

(-24y/2)^2 = 144

x^2 + 16x + 64 + y^2 - 24y + 144 = -159 + 144 + 64

x^2 + 16x + 64 + y^2 - 24y + 144 = 49

Reduce the trinomials to binomials:

(x + 8)^2 + (y - 12)^2 = 49

Thus the center point is (-8, 12) and the radius is 7

The part (aka "is") = 8 and the percent is 42, what is the whole (aka
marysya [2.9K]

Answer:

33

Step-by-step explanation:

If you simplify what the question is saying, it's basically..

8 is 24% of <u>what number?</u>

To find out, you can simply set up an equation.

((24% = 0.24 as a decimal (move the decimal point two times to the left))

8 = 0.24 x N (N is just the 'whole')

To solve, you just need to divide 8 ÷ 0.24. So, N = 33.333 repeating.

The question says to round to the nearest whole number, so the answer would just be 33.

A line passes through the points (7, 3) and (8, 3). What is its equation in slope-intercept form?
Sati [7]

Answer:

y=3

Step-by-step explanation:

The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.

Therefore, the slope-intercept equation is

y=3
