Answer and Step-by-step explanation:

$\huge\boxed{r=-7}$

Step 1: Subtract 6r from both sides:

$5r-2-6r=6r+5-6r$

$-r-2=5$

Step 2: Add 2 to both the sides:

$-r-2+2=5+2$

$-r=7$

Step 3: Divide both sides by -1:

$\frac{-r}{-1} =\frac{7}{-1}$

$r=-7$

What are the coordinates of the point? A coordinate grid with a dot placed in the second quadrant. The dot is to the left of pos

GenaCL600 [577]

We know that the point is in Q II. Thus, the x-coordinate of this point will be negative and the y-coordinate will be positive.

The y-coordinate is essentially given, and is y=4.
Imagine drawing a vertical line thru x=-2. This line will intersect y=4 at (-2,4).

The coordinates of the point are (-2, -4).

If the spray paint costs approximately $1.50 per foot of coverage, how much should the coach budget for the spray paint?

torisob [31]

Since the cost of the spray paint is approx $1.50,

The range for the cost of the spray paint is'

$\pm0.05\text{ dollars}$

Therefore, the coach budget should be between,

$\begin{gathered} \text{for }+0.05\text{ dollars,} \\ =1.5+0.05=1.55\text{ dollars and,} \\ \text{for -0.05 dollars,} \\ =1.5-0.05=1.45\text{ dollars} \end{gathered}$

Hence, the budget of the coach should be between $1.45 and $1.55.

The sum of two consecutive even integers is 106. what are the integers

jolli1 [7]

Let the consecutive even integers be x and (x+2).

x + (x + 2) = 106

2x + 2 = 106

2x = 104

x = 52

Thus the two integers are 52 and 54.

I need answer and specific explanation plz...

Answer:

The smallest model - bottom right - in the question diagram represents $\sqrt[3]{64}=4$ .

Step-by-step explanation:

Considering the radical expression

$\sqrt[3]{64}$

Lets simply this radical expression first

$\sqrt[3]{64}$

$\mathrm{Factor\:the\:number:\:}\:64=4^3$

$=\sqrt[3]{4^3}$

$\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a^n}=a,\:\quad \:a\ge 0$

$\sqrt[3]{4^3}=4$

$=4$

Therefore, $\sqrt[3]{64}=4$

Now, as we can determine that $\sqrt[3]{64}=4$ . So, the smallest model in the question diagram represents $\sqrt[3]{64}=4$ as each face of the cube of the smallest model in the diagram - bottom right - has 4 squares.

Therefore, the smallest model - bottom right - in the question diagram represents $\sqrt[3]{64}=4$ .

14 + 10y ≥ 3(y + 14) <br> A. y ≥ –4<br>B. y ≥ 4 <br>C. y ≥ 8<br>D. y ≥ 6

arsen [322]

Answer:

Step-by-step explanation:

Given

14 + 10y ≥ 3( y + 14) ← distribute

14 + 10y ≥ 3y + 42 ( subtract 3y from both sides )

14 + 7y ≥ 42 ( subtract 14 from both sides )

7y ≥ 28 ( divide both sides by 7 )

y ≥ 4 → B
