-6 ( 10x-4) Use the distributive law:-

= -60x + 24

(-y+5.3)+ (7.2y -9) First remove parentheses:-

= -y + 5.3 + 7.2y - 9 Now add like terms:-

= 7.2y - y -9 + 5.3

= 6.2y - 3.7

5-8(4-1v +3v)

= 5 - 32+ 8v - 24v

= -27 - 16v

-10 ( 3+ 10v) -9v

= -30 - 100v - 9v

= -30 - 109v

30/45G + 20) - ( 8/9G + 7) Converting:- 8/9G = 40/45G :-

= 30/45G - 40/45G + 20 - 7

= -10/45G + 13

= -2/9G + 13

Under his cell phone plan, Ian pays a flat cost of $59.50 per month and $5 per gigabyte. He wants to keep his bill under $80 per

inessss [21]

You would start by saying his budget is $80 so you start with 80= he pays an initial fee of $59.50 every month plus $5 per gigabyte so you would set it up like
80=59.50+5x
X being how many gigabytes he uses then you solve 80-59.50 is 20.5 divided by 5 gives you 4.1 but you round down cause you don’t want to pass the limit so therefor the most gigabytes he can use is 4

8xy= 2(2x + y) solve for y

STatiana [176]

Answer: $\displaystyle y= \frac{2\text{x}}{4\text{x} - 1}$

============================================

Work Shown:

$8\text{x}y= 2(2\text{x} + y)\\\\8\text{x}y= 4\text{x} + 2y\\\\8\text{x}y - 2y= 4\text{x}\\\\y(8\text{x} - 2)= 4\text{x}\\\\y= \frac{4\text{x}}{8\text{x} - 2}\\\\y= \frac{2*2\text{x}}{2(4\text{x} - 1)}\\\\y= \frac{2\text{x}}{4\text{x} - 1}\\\\$

---------------

Explanation:

The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.

Then factor out y and divide both sides by (8x-2)

Afterward there's the optional steps of simplifying (as shown in the final two steps).

Carlos drew a plan for his garden on a coordinate plane. Rose bushes are located at A(–5, 4), B(3, 4), and C(3, –5)

BartSMP [9]

Given:

A(-5,4)

B(3,4)

C(3,-5)

So point D is:

so point D is (-5,-5)

For AB is

Distance between two point is:

$\begin{gathered} (x_1,y_1)and(x_2,y_2) \\ D=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \end{gathered}$

so distance between A(-5,4) and B(3,4) is:

$\begin{gathered} D=\sqrt[]{(3-(-5))^2+(4-4)^2} \\ =\sqrt[]{(8)^2+0^2} \\ =8 \end{gathered}$

So AB is 8 unit apart.

For B(3,4) and C(3,-5).

$\begin{gathered} D=\sqrt[]{(3-3)^2+(-5-4)^2} \\ =\sqrt[]{0^2+(-9)^2} \\ =9 \end{gathered}$

So BC is 9 unit apart.

For fourth bush point is (-5,-5) it left of point C(3,-5) is:

$\begin{gathered} D=\sqrt[]{(3-(-5))^2+(-5-(-5))^2} \\ =\sqrt[]{(8)^2+0^2} \\ =8 \end{gathered}$

so fourth bush is 8 unit left of C.

For fourth bush(-5,-5) below to point A(-5,4)

$\begin{gathered} D=\sqrt[]{(-5-(-5))^2+(4-(-5))^2} \\ =\sqrt[]{0^2+9^2} \\ =9 \end{gathered}$

so fourth bush 9 units below of A.

Solve (x - 5)2 = 3.O A. x = -51 1/3O B. x = 3 15O C. x = 5+:13O D. x = 8 and x = -2

Virty [35]

In order to solve the given expression follow these steps:

1. Take the square roots on both sides in order to get rid of the power on the left side:

√(x-5)² = ±√3

x - 5 = ±√3

2. add 5 on both sides:

x-5 + 5 = 5 ±√3

x = 5 ±√3

Then, the solution is x = 5 ±√3

WILL GIVE BRAINLIEST!! FINALS!

GenaCL600 [577]

Factor completely x³ + 6x² - 3x – 18
$- 6 + 6( - 6)^{2} - 3( - 6) - 18 \\ - 6 +6 \times 6 ^{2} + 18 - 18 \\ - 6 + 6 ^{3} + 18 - 18 \\ - 6 + 216 \\ 210$
with a root of x = -6

the answer is 210
