Use the expression below to answer the question. 20 + 8y – 9y – 21 Which expression is equivalent? A. 2(10 + 4y – 7y – 19) B. 2(
Amanda [17]

Option D: 4(5+2y)-3(3y+7) is the correct answer.

Explanation:

The expression is $20+8 y-9 y-21$

Solving the expression, we have,

-y-1

Now, we need to find an expression equivalent to $20+8 y-9 y-21$

Option A: 2(10+4y-7y-19)

Solving the expression, we have,

$\begin{aligned} 2(10+4 y-7 y-19) &=2(-9-3 y) \\ &=-18 y-6 y \end{aligned}$

From the result, the expression 2(10+4y-7y-19) is not equivalent to $20+8 y-9 y-21$

Option A is not the correct answer.

Option B: $2(10+4 y)-3(3 y-7)$

Solving the expression, we have,

$\begin{aligned} 2(10+4 y)-3(3 y-7) &=20+8 y-9 y+21 \\ &=-y+41 \end{aligned}$

From the result, the expression $2(10+4 y)-3(3 y-7)$ is not equivalent to $20+8 y-9 y-21$

Option B is not the correct answer.

Option C: 4(5+2y-5y-17)

Solving the expression, we have,

$\begin{aligned} 4(5+2 y-5 y-17) &=20+8 y-20 y-68 \\ &=-12 y-48 \end{aligned}$

From the result, the expression 4(5+2y-5y-17) is not equivalent to $20+8 y-9 y-21$

Option C is not the correct answer.

Option D: $4(5+2 y)-3(3 y+7)$

Solving the expression, we have,

$\begin{aligned} 4(5+2 y)-3(3 y+7) &=20+8 y-9 y-21 \\ &=-y-1 \end{aligned}$

From the result, the expression $4(5+2 y)-3(3 y+7)$ is equivalent to $20+8 y-9 y-21$

Option D is not the correct answer.

Write an equation of the line that passes through (2, -3) and is perpendicular to the line y=-2x-3
Natalija [7]

Answer:

y=\frac{1}{2} (x-2)-3 or y=\frac{1}{2} x-4

Step-by-step explanation:

The perpendicular slope is the opposite-reciprocal of the original slope:

Perpendicular slope of -2 is \frac{1}{2}

Write the equation in point-slope form (y=a(x-h)+k):

y=\frac{1}{2} (x-2)-3

Convert to slope-intercept form if needed:

y=\frac{1}{2} x-1-3

y=\frac{1}{2} x-4
