Answer:

A) -28r + 21

Step-by-step explanation:

-7(4r -3)

Distribute the -7

-7*4r -7*(-3)

-28r +21

For this case we must simplify the following expression:

$-7 (4r-3)$

We apply distributive property to the terms within the parenthesis taking into account that $- * + = -$ and $- * - = +$ .

The distributive property states that:

$a (b + c) = ab + ac$

So:

$-28r + 21$

Answer:

$-28r + 21$

Option A

The value of sports team decreases at a steady rate of 20% each year. What is the total percentage loss (to the nearest integer)

Shtirlitz [24]

It would be 80% since it decreases 20% each year so 20*4 is 80 so it’s 80%

Triangles and algebra

Hello from MrBillDoesMath!

Answer:

x = 10

Discussion:

A plane triangle contains 180 degrees. Adding the angles in the triangle shown in #8 gives

(4x + 7) + (3x + 13) + 90 = 180

Note the "right angle" shown in the triangle has been replaced by its 90 degree equivalent in the above equation.

Combining like terms gives

( 4x + 3x) + (7 + 13) + 90 = 180

7x + 20 + 90 = 180 => (subtract 90 from each side)

7x + 20 + 90 - 90 = 180 - 90 = 90 =>

7x +20 = 90 => (subtract 20 from each side)

7x + 20 -20 = 90 -20 =>

7x = 70 =>

x 70/7 =10.

Thank you,

MrB

Help please and thank you

Answer:

Step-by-step explanation:

We assume the rotation R is <em>counterclockwise</em> 60°.

The exponent on R is the number of times it is applied. That is, R² = R(R(figure)). So, the composition is equivalent to R^(2-4) = R^-2.

When the exponent of R is negative, it is essentially the inverse function. That is, applying the function R to the result will give the figure you started with. Equivalently, it is rotation in the other direction.

$(\mathcal{R}^2\circ\mathcal{R}^{-4})(\text{figure})=\mathcal{R}^{-2}(\text{figure})=\text{figure rotated $120^{\circ}$ CW}$

The point 120° clockwise from B is D.

The desired image point is D.
