Answer:

$\huge \boxed{\mathrm{-1}}$

Step-by-step explanation:

$(5xe^2 - 3x) - (5xe^2 - 3x+1)$

Distribute negative sign.

$5xe^2 - 3x- 5xe^2 +3x-1$

Combine like terms.

$0xe^2 +0x-1$

$0-1=-1$

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?

ale4655 [162]

Answer:

(x + 4)^2 + (y – 9)^2 = 25

Step-by-step explanation:

The standard form for a circle is

$(x - h)^{2} + (y - k)^{2} = r^{2}$ where (h, k) is the center and r is the radius

In your case, h = -4 and k = 9 and r = 5

So, (x + 4)^2 + (y – 9)^2 = 25

If G is the midpoint of FH, FG= 14x + 25 and GH = 73- 2x, find FH

Alenkinab [10]

Given that G is the midpoint of FH, then:
FG=GH
hence;
14x+25=73-2x
solving for x we get:
14x+2x=73-25
16x=48
x=48/16
x=3
therefore the length FG=14x+25 will be:
14*3+25
=67
hence FH will be:
FH=67*2=134

Here's a graph of a linear function. Write the

bazaltina [42]

Answer:

Step-by-step explanation:

The formula is y = mx + b

m being the slope, rise over run. And b being the y-intercept. Right off the bat we can visually see the y-intercept is -4.

To find slope, we need to take two sets of coords and apply the slope fomula. The slope fomula is change in y divided by the change in x. The function itself is straight, so that means the slope will be the exact same no matter which points you choose.

(4, -1) and (8, 2) are coords on the line. Do 2 - (-1) to get 3. then do 8 - 4 to get 4. Finally, we just gotta do 3/4 which is simply $\frac{3}{4}$ .

We have the slope of 3/4 and we have the y-intercept of -4. Just plug it in the standard formula of y = mx + b to get:

$y=\frac{3}{4} x-4$
