Please answer correctly !!!!! Will mark brainliest answer !!!!!!!!!!
AnnZ [28]

Answer:

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

x_{vertex}= -b/2a

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

f(-13/4)= -9/8

Then your expression for this quadratic should be:

f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one

5(x+7)+2 = 4(x - 1) + 1
Nadya [2.5K]

Answer:

x = -40

Step-by-step explanation:

First we distribute

5x + 35 + 2 = 4x - 4 + 1

Collect like terms

5x + 37 = 4x - 3

Subtract 37 from both sides

5x = 4x - 40

Subtract 4x from both sides

1x = -40 OR x = -40

Which equations have infinitely many solutions?
igomit [66]

Answer:

4(x - 1) = 4x - 4

3x + 6 = 3(x + 2)

Step-by-step explanation:

The first equation is

5x - 1 = 5x + 1

We simplify to get;

- 1 = 1

This is not true, therefore this equation has no solution.

The second equation is

3x - 1 = 1 - 3x

Combine like terms:

3x + 3x = 1 + 1

6x = 2

x =  \frac{1}{3}

This has a unique solution.

The 3rd equation is

7x - 2 = 2x - 7

Group similar terms:

7x - 2x =  7 + 2 \\ 5x = 9 \\ x  =  \frac{9}{5}

The 4th equation is :

4(x - 1) = 4x - 4

4x - 4= 4x - 4 \\ x = x

This is always true. The equation has infinite solution.

The 5th equation is:

3x + 6 = 3(x + 2) \\ 3x + 6 = 3x + 6 \\ x = x

This also has infinite solution

The 6th equation is

3(x - 4) = 4(x - 3) \\ 3x - 12 = 4x - 12 \\ 3x - 4x =  - 12 + 12 \\ x = 0

It has a unique solution.
