Answer:

C=6

Step-by-step explanation:

The strategy that I use is inverse operations.

Add 6 to 12, as the equation has "-6". 6+12=18

Now, to find C, we simply divide 18 by 3, as the remaining equation was "3c", which is multiplication.

18/3=6

Therefore, c=6.

To ensure that the answer is correct, plug in the 6 to see if its true.

3(6)-6

18-6=12

What is the slope of the linear function thats passes through the points (9,-2) and(-4,-6)

stiv31 [10]

Answer:

slope = $\frac{4}{13}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (9, - 2) and (x₂, y₂ ) = (- 4, - 6)

m = $\frac{-6+2}{-4-9}$ = $\frac{-4}{-13}$ = $\frac{4}{13}$

50 Points What is the value of r? 6.4r−5.9r=−3.25 Question 1 options: A -6.5 B 6.5 C -3

Oliga [24]

Answer:

Option A. -6.5

Step-by-step explanation:

we have

$6.4r-5.9r=-3.25$

Solve for r

That means ---> isolate the variable r

Combine like terns left side of the equation

$0.5r=-3.25$

Divide by 0.5 both sides

$0.5r/0.5=-3.25/0.5$

$r=-6.5$

Alyssa is painting her bedroom blue. Each of four walls has dimensions 12.9 ft by 9.9 ft. How much area will she paint?

elixir [45]

Answer:

510.84 ft²

Step-by-step explanation:

Given that,

dimensions of wall = 12.9ft by 9.9ft

height of wall = 12.9ft

width of wall = 9.9ft

there are total 4 walls in a bedroom to be painted blue.

Formula to calculate area of one wall

<h3>Height x Width</h3>

Formula to calculate area of four walls

<h3>4 (Height x Width)</h3>

= 4( 12.9ft x 9.9ft)

= 4 (127.71 ft²)

= 510.84 ft²

So area Alyssa will paint = 510.84 ft²

<em>(assuming she will paint only wall s of her room not the ceiling)</em>

The gravitational attraction betweentwo bodies varies inversely as thesquare of the distance between them.If the force of attrac

Sliva [168]

The force for the case 1 is 64 pounds and the distance is 9 feet, it is:

$\begin{gathered} \frac{k}{9^2}=64 \\ k=5184 \end{gathered}$

Now, if the force is 36 pounds, let solve for the distance:

$\begin{gathered} \frac{k}{r^2}=36 \\ \frac{5184}{r^2}=36 \\ r^2=144 \\ r=12 \end{gathered}$

Hence the answer is 12 feet.
