Answer:

center=(-7,5)

Step-by-step explanation:

The center form of the circle equation is in the format (x – h)^2 + (y – k)^2 = r^2, with the center being at the point (h, k).

you can find center by making equal to zero each term, then:

x+7 = 0

x=-7

y-5 = 0

y=5

then the center is (-7,5).

What are the x-intercepts of 4x^ + 8x - 5

mojhsa [17]

Assuming the exponent is supposed to be "^2" your equation will read:

4x² + 8x - 5

It must set equal to y to be a valid function and the y must be set equal to zero to find x-intercepts.

4x² + 8x - 5 = 0
4x² - 2x + 10x - 5 = 0
2x(2x - 1) + 5(2x - 1) = 0

(2x + 5)(2x - 1) = 0

Set each binomial equal to zero.

2x + 5 = 0
2x = 0 - 5
2x = - 5
Divide both sides by 2
x = - 5/2

2x - 1 = 0
2x = 0 + 1
2x = 1
x = 1/2

Your x-intercepts are x = - 5/2, 1/2 or (- 5/2, 0) and (1/2, 0)

Answer: hello your question is incomplete attached below is the missing part

answer : There is no slope

Step-by-step explanation:

To interpret the slope we plot a graph of Winter severity index vs Fawn count

slope = Δy / Δx = 0

attached below is the graph

There no slope because the graph is a curve and not a straight line graph

Lesechka [4]

$c=\frac{5y}{4\\} + \frac{7}{4\\}$

$x=-\frac{y}{2} + \frac{7}{2}$

Step-by-step explanation:

if 'c' is meant to be another 'x' the answer is

(3, 1)

x = 3,y = 1

Solve 6 - 2x = 3<br><br> How do I do this?

RoseWind [281]

Answer:

x = 3/2 or 1.5

Step-by-step explanation:

6 - 2x = 3

(You have to subtract 6 on both sides so it can cancel out)

6 - 6 - 2x = 3 - 6

-2x = -3

(Now, you divide -2 on both sides to isolate the x)

-2/(-2)x = -3/(-2)

x = 3/2
