u + 2 =  - 8 \\  =  > u =  - 8 - 2 \\  =  > u =  - 10

<h3>The answer is -10.</h3>

<h2>Answer: u = -10</h2>

Step-by-step explanation:

We are given the equation <em>u + 2 = -8</em>, and we need to find the value of <em>u</em>. In order to do that, u needs to be by itself on one side of the equation, and numeral by itself on the other side.

The way to do this is by subtracting <em>2 </em>from each sided of the equation. This successfully isolates u and gives us the equation <em>u = -10</em>, which is our answer.

u + 2 = -8

u + 2 -2= -8 -2

u=-10

Hope this helps! Have a great day!

What is the slope of the line that passes through the points (8,-8) and (5,-1)?
dezoksy [38]

Hey there!

  • Answer :

\sf{ \purple{ \boxed{\bold{m =  -  \dfrac{7}{3} }}}}

\\

  • Explanation :

We are given the points \sf{P_1(\overbrace{ \blue{8}}^{\blue{x_1}} ,\underbrace{\orange{-8}}_{ \orange{y_1}}) \: and \: P_2(\overbrace{ \green{5}}^{\green{x_2}} ,\underbrace{\red{-1}}_{\red{y_2} })} . To find the slope \sf{\purple{m}} of such a line, we use the slope formula which is the following:

\sf{ \purple{m} }=  \dfrac{\Delta y}{\Delta x}  =  \dfrac{ \red{y_2} - \orange{y_1}}{ \green{x_2 }- \blue{x_1}}

\\

⇢Now, by plugging in our values, we get :

\sf{ \purple{m}} =  \dfrac{ \red{ - 1} -  \orange{( - 8)}}{ \green{5} \:   -  \:  \blue{8}}  =  \dfrac{ \:  \: 7 \: }{ -  3 \: }  \\  \\  \implies \sf{ \purple{ \boxed{m =  -  \dfrac{7}{3} }}}

Therefore, the slope of the line is \sf{ \purple{ \boxed{m =  -  \dfrac{7}{3} }}}

Using the equation y = two-thirds x minus 5, describe how to create a system of linear equations with an infinite number of solu
ICE Princess25 [194]

Answer:

To have an infinite number of solutions, the equations must graph the same line. That means the equations must be equivalent. To form an equivalent equation, use the properties of equality to rewrite the given equation in a different form. Add, subtract, multiply, or divide both sides of the equation by the same amount.

Step-by-step explanation:

it's the sample answer

The distance d (in miles) you travel in a car is given by the two equations shown, where t is the time (in hours) and g is the n
lana [24]

We have two equations  d=55t and d=20g

The left sides of this equations are the same than the right sides are equal too

a)    55t=20g

b)   g=(55/20)t

c)  t=6h => g=(55/20) *6 = 165/10=16.5 gallons

d= 55t= 55*6=330 miles or d=20g=20*16.5=330 miles

Good luck!!!

Please select the most simplified form of the equation. −12x + 26 = 1x
Damm [24]

Answer:

x=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−12x+26=x


Step 2: Subtract x from both sides.


−12x+26 − x = x − x


−13x+26=0


Step 3: Subtract 26 from both sides.


−13x+26−26=0−26


−13x=−26


Step 4: Divide both sides by -13.


−13x/−13  =  −26/−13


x=2
