Answer:

Slope - intercept form:

B) y= x -4

Step-by-step explanation:

(3,-1) and (-1,-5)

Slope = (-5 + 1)/(-1 - 3)

Slope = -4 / -4

Slope = 1

Point slope form:

y + 1 = 1 (x - 3)

y +1 = x - 3

y = x - 4 <------------------slope - intercept form

1 = -3(-2) + b

1 = 6 + b

-5 = b

Answer:

-2

<em>BRAINLIEST, PLEASE!</em>

Step-by-step explanation:

5 - 3(2a + 1) = -4a + 10

5 - 6a - 3 = -4a + 10

2 - 6a = -4a + 10

-2a = 8

a = -4

Answer:

3.98 meters

Step-by-step explanation:

First we need to know the formula for finding the height of a cylinder

$h=\frac{V}{\pi r^2}$

Now That we know our formula, we just need to put in our numbers and simplify

$h=\frac{5000}{\pi 20^2}$

$h=\frac{5000}{1256.637}$

$h=3.97887$

2x^{2} +4x+1=0 <br> Solve for x.

Viefleur [7K]

2x^2 + 4x + 1 = 0

2x^2 + 4x + 1 - 1 = 0 - 1

2x^2 + 4x = -1

X(2x + 4) = -1

X = -1.

2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.

I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.
