(7 - b) + (3b + 2)

Open the parentheses (this is a simple addition question so there's no need to do anything)

7 - b + 3b + 2

Rearrange (not necessary but makes it easier)
3b - b + 7 + 2
2b + 9

-T.B.

Find the slope of the line that passed though the two points <br> (0,5) and (-9, -4)
OverLord2011 [107]

To find the slope, use the slope(m) formula:

m=\frac{y_2-y_1}{x_2-x_1}        and plug in the two points

(0, 5) = (x₁, y₁)

(-9, -4) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-4-5}{-9-0}

m=\frac{-9}{-9}    [two negatives cancel each other out and become positive]

m = 1      The slope is 1

Somebody help this is algebra
jeyben [28]

Answer:

2 is your answer

Step-by-step explanation:

If h(x)= 5 then 5= 2x +1

so 5 = 2x + 1

   -1            -1 on both sides

then 2x = 4

        2      2 divide by 2

which x = 2

Hope my answer has helped you!

Simplify\:\sqrt[3]{27x^{15}}y^{24}
Free_Kalibri [48]

Answer:

3x^{5}y^{24}

Step-by-step explanation:

\sqrt[3]{27x^{15}}y^{24} =

= \sqrt[3]{3^3x^{15}}y^{24}

= (3^3x^{15})^{\frac{1}{3}}y^{24}

= (3^3)^{\frac{1}{3}}(x^{15})^{\frac{1}{3}}y^{24}

= 3^{3 \times \frac{1}{3}}x^{15 \times \frac{1}{3}}y^{24}

= 3^1x^{5}y^{24}

= 3x^{5}y^{24}
