Answer:

Your y intercept is 1.

Step-by-step explanation:

slope is y2-y1 over x2-x1, or 2.

slope intercept formula is y=mx+b, and if you plug values into formula you get 3=2(1)+b

and if you solve that, 2x1=2, 3-2=1.

then you get 1 as your y intercept.

-16x + 44

Solution:

4(3×2 - 4x + 5)

= 4( 6 - 4x + 5)

=4( -4x + 11)

= -16x + 44

A piece of pipe is 303/4 inches long. If five pieces, each 41/3 inches long, are cut from the pipe, how many inches of pipe rema

galina1969 [7]

So, what is the total lenght of the pieces that wer cut off?

we multiply the lenght by the number:

4 $\frac{1}{3}$ *5=20+ $\frac{5}{3}$ =21 $\frac{2}{3}$

and we subtract this from the original pipe, that is

30 $\frac{3}{4}$ -21 $\frac{2}{3}$

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):

30 $\frac{9}{12}$ -21 $\frac{8}{12}$ =9 $\frac{1}{12}$

so the correct answer is D!

Sole m-2/12=1/6 a.4 b.1 c.0 d.2

riadik2000 [5.3K]

The answer would be A. 4
Here’s what I would do.
Multiply both sides by 12 so u can get m- 2 by itself.
m-2= 2
How’d I get the two? It comes from when I multiplied 12 on both sides. 12/6= 2
Now ur equation should be
m-2=2
Do the opposite and add two to both sides to get the variable by itself.
m=4

Hope this helps :)))

Parabolas y=−2x^2 and y=2x^2 +k intersect at points A and B that are in the third and the fourth quadrants respectively. Find k

OverLord2011 [107]

Answer:

-25

Step-by-step explanation:

(1) y = -2x²

(2) y = 2x² + k Subtract (1) from (2)

0 = 4x² + k Subtract 4x² from each side

k = -4x²

The parabolas are symmetrical about the y-axis.

Segment AB = 5, so x = +2.5 and x = +2.5.

k = -4(±2.5)² = -4 × 6.25 = -25
