Answer:

$\frac{2}{3} (x+6)$

Step-by-step explanation:

$\frac{2}{3} x+4=$ $\frac{2}{3}$ ( $x$ +4÷ $\frac{2}{3}$ )

$\frac{2}{3}x+4$ = $\frac{2}{3}$ ( $x$ +4× $\frac{3}{2}$ )

$\frac{2}{3}x+4$ = $\frac{2}{3}$ ( $x$ + $\frac{12}{2}$ )

$\frac{2}{3}x+4$ = $\frac{2}{3}$ $(x+6)$

Answer:

I think the answer would be -21%!

Step-by-step explanation:

-4/5 = -0.8 would be behind -.05

- 0.7 would be behind -.05

-21% = -0.21 correct answer

- square root of 1 = -1 too far from 0

Good Luck. Hope this helped.

Peter hired a cleaning company to clean his house. The cleaning company charges a fixed fee of $15 plus $17 per hour to clean a

almond37 [142]

Answer:

5 (for c only)

Step-by-step explanation:

for c:

1st cleaning company: $y=17x+15$

2nd cleaning company: $y=20x$

set up as a system of equations. for them to cancle out make the y of one equation negative. I'll be making the second one negative ( it doesn't matter though)

it will look like:

$y=17x+15$

$-y=-20x$

make the two equations on top of eachother and line the terms up. Then combine them. The variable "y" will cancle out and you'll be left with

$0=-3x+15$

then you will add 3x to both sides to get $3x=15$ then divide both sides by 3 to get $x=5$

if you plug in 5 for x into both of the original equations you will see that they will both make $100 in five hours. So you answer is 5

In ΔEFG, the measure of ∠G=90°, the measure of ∠E=40°, and EF = 75 feet. Find the length of GE to the nearest tenth of a foot

juin [17]

Answer:

19.4 feet

Step-by-step explanation:

Since the triangle has a right angle( as one of the angles in it is equal to 90°), we may find the length of the unknown side using the trigonometric notations SOH CAH TOA where

SOA stands for

Sin Ф = opposite side/hypotenuses side

Cosine Ф = adjacent side/hypotenuses side

Tangent Ф = opposite side/adjacent side

Given that the measure of ∠G=90° and ∠E=40°

EF is the hypotenuse side

FG is the opposite side and

GE is the adjacent side. As such if EF = 75 feet

Cos 75 = GE/75

GE = 75 Cos 75°

= 19.41 feet

≈ 19.4 feet in the nearest tenth of a foot

What is an equation of the line that passes through the point (-2, -3) and is

mrs_skeptik [129]

Answer: 2y + 5x + 16 = 0

Step-by-step explanation:

To solve this you need to understand the principle/ conditions for parallelism and perpendicularity.

for two lines to be parallel to each other, their gradients or slopes (m) must be equal, that is m₁ = m₂

Now from the given equation,

5x + 2y = 14 , we need to rearrange it to conform to the equation of a straight line so that the gradient could be established. ie

y = mx + c where m is the gradient

2y = -5x + 14

y = -5x/2 + 14/2

y = ⁻⁵ˣ/₂ + 7 , therefore , m₁ = ⁻⁵/₂ and m₂ = ⁻⁵/₂ ( parallelism Rule )

The next step is to find the value of C using the coordinate ( -2, -3 )

-3 = ⁻⁵/₂ ˣ ⁻² + C,

-3 = ¹⁰/₂ + C

-3 = 5 + C

C = -8.

Now to find the equation of the line that passed through the coordinate

y = mx + c

y = ⁻⁵ˣ/₂ - 8

2y = -5x - 16

2y + 5x + 16 = 0.
