5k - 9 = 5k + 2

move 5k to the left side

sign changes from+5k to -5k

5k-5k-9=5k-5k+2

0-9= 0+2

-9=2

Answer:

A. 51°

Step-by-step explanation:

By the theorem of intersecting secants.

$m\angle B=\frac{1}{2} (m\widehat{LW} - m\widehat{MU})$

$44.5\degree =\frac{1}{2} (140\degree - m\widehat{MU})$

$2\times 44.5\degree = 140\degree - m\widehat{MU}$

$89\degree = 140\degree - m\widehat{MU}$

$m\widehat{MU} = 140\degree -89\degree$

$m\widehat{MU} = 51\degree$

What is an equation that goes through the point (-7, 10) and is perpendicular to the line -2x-4y=9

algol13

Step-by-step explanation:

m1.m2= -1

(4y = -2x -9)= (y = -1x/2 -9/4)

-1/2.m2= -1

m2 = 2

formula = y - y1 = m2 ( x - x1)

y - 10 = 2 ( x - (-7))

y - 10 = 2x + 14

y = 2x + 24

Answer:

$x =320$

Step-by-step explanation:

Given

$x^2 + 200x = 166400$

Required

Find x

We have:

$x^2 + 200x = 166400$

Rewrite as:

$x^2 + 200x - 166400 = 0$

Expand

$x^2 + 520x - 320x - 166400 = 0$

Factorize

$x(x + 520) - 320(x + 520)= 0$

Factor out x + 520

$(x - 320) (x + 520)= 0$

Split

$x - 320 = 0\ or\ x + 520= 0$

Solve

$x = 320\ or\ x =- 520$

Side length must be positive;

So:

$x = 320$

The water is flowing into the pool at 1.5 gallons per minute and it would take 20 minutes to be filled.

<h3>What is an Equation</h3>

An equation is used to show the relationship between two or more numbers and variables.

The pool holds 30 gallons of water. After 5 minutes, the pool is about one fourth full. Hence:

Time to full the pool = 5 minutes * 4 = 20 minutes

Rate of water flow = 30 gallons/20 minutes = 1.5 gallons per minute

The water is flowing into the pool at 1.5 gallons per minute and it would take 20 minutes to be filled.
