Write -2x as a difference
x^2 + 5x -7x - 35

Factor out x from the expression
x(x+5) -7x - 35

Factor out (x+5) from the expression
(x+5) (x-7)

A line goes through the point (–4,–2) and has an x-intercept of –1. Which point also lies on the line? 
Yuki888 [10]
Im not getting exact answers but the closest was D. What i did was i graphed the points and i found the slope and then i found the y intercept. so the equation was y = 2/3x + .67. and i plugged in the points. so i would say the answer is D. because since i rounded the .67 it wasn't exact but it was close

Point E is the midpoint of AB and point F is the midpoint
GREYUIT [131]

The options are;

1) AB is bisected by CD

2) CD is bisected by AB

3) AE = 1/2 AB

4) EF = 1/2 ED

5) FD= EB

6) CE + EF = FD

Answer:

Options 1, 3 & 6 are correct

Step-by-step explanation:

We are told that Point E is the midpoint of AB. Thus, any line that passes through point E will bisect AB into two equal parts.

The only line passing through point E is line CD.

Thus, we can say that line AB is bisected by pine CD. - - - (1)

Also, since E is midpoint of Line AB, it means that;

AE = EB

Thus, AE = EB = ½AB - - - (2)

Also, we are told that F is the mid-point of CD.

Thus;

CF = FD

Point E lies between C and F.

Thus;

CE + EF = CF

Since CF =FD

Thus;

CE + EF = FD - - - (3)

Find the missing side of this right
navik [9.2K]

Answer:

x = 13

Step-by-step explanation:

First start with the blank equation

a^{2} + b^{2} = c^{2}

Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.

5^{2} + 12^{2} = c^{2}

Then solve

25 + 144 = c^{2}

169 =c^{2}

\sqrt{169} = \sqrt{c^{2} }

c = 13

I bet you 10 points you will not answer this<br><br> I think its B i need assurance
Flauer [41]

Answer:

(a) seems to be the closest to being correct of these five statements.

Step-by-step explanation:

Let's go through the list of possible descriptors:

a) There are no outliers.  This seems to be the response most likely to be correct.

b) The distribution is not skewed left.  It's skewed right.

c) The center is not 44.  From what I see, the center is 48.

d) This distribution is not bimodal; it does not have two peaks.

d) The spread is not 38 to 67; it's 29 to 67.
