The answer would be B.

To properly solve the answer you would have to leave \frac{2}{3} alone and change the division sign into multiplication. Then, do reciprocal of \frac{4}{5}.

In this case the person did not do the reciprocal of \frac{4}{5}.

So, the answer is B

In the division a/b, a is the dividend, and b is the divisor.

In this problem, 2/3 is the dividend, and 4/5 is the divisor.

She needed to multiply the dividend, 2/3, by the reciprocal of the divisor, 5/4.

Instead, she multiplied the dividend by the divisor without using the reciprocal.

Answer: second choice

Determine the next step for solving the quadratic equation by completing the square.
Lady_Fox [76]

Answer:

-7/2 = -2(x-1/2)^2

Step-by-step explanation:

0 = –2x^2 + 2x + 3

Subtract 3 from each side

-3 = –2x^2 + 2x

Factor out the -2

-3 =- 2(x^2 -x)

Take the coefficient of x and divide by 2 and square it

-1 /2 = -1/2 ^2 = 1/4

Add it to each side  Remember the -2 on the outside so we need to multiply it by -2  

-2 *1/4 =  -1/2

-3 -1/2= -2(x^2 -x +1/4)

-7/2 = -2(x^2 -x +1/4)

-7/2 = -2(x-1/2)^2

motikmotik

Answer:

32

Step-by-step explanation:

f(x)= 3(x-2)² + 5

Let x = -1

f(-1)= 3(-1-2)² + 5

Parentheses first

f(-1) = 3(-3)^2 +5

Exponents

f(-1)= 3*9 + 5

Multiply

f(-1) = 27+5

Add

f(-1) = 32
