Answer:

<h2>33/4 </h2><h2>or as a mixed number</h2><h2>8 1/4</h2>

Step-by-step explanation:

-2x + 3 = 0

-2x = -3

x = 3/2

-x^2 + 2x + 3 = (-3/2)^2 + 2 × 3/2 + 3

= 9/4 + 3 + 3

= 9/4 + 6

= 33/4

or 8 1/4 as a mixed number

Help me pleeeeeeeeeeease
erastovalidia [21]

Answer:

3.

Step-by-step explanation:

If Andre's representation is correct, that the slope is 3. The question is confusing me a bit, because it isn't very clear, but Andre's Representation is in Point Slope Form, (y=mx+b) where m represents the slope. So again, if Andre's representation is for the graph and is correct, the slope is 3.

Slove this inequality 3b-7 less the 20
Mars2501 [29]

Hi friend

#24

y/9+5=0

Simplify to both sides

1/9 y+5=0

Now subtract 5 from both sides

1/9 y+5-5=0-5

1/9 y=-5

Multiply both sides by 9 so we can find the y value

9(1/9 y)= (9)(-5)

y=-45

The answer is A ( Your answer was not good)


#25

3b-7<32

First you need to add 7 to both sides

3b-7+7=32+7

3b<39

Now divide both sides by 3 so we can find the value for b

3b/3<39/3

b<13

The answer is A


#26

3p-16<20

Now we gonna do the same thing

Add 16 to both sides

3p-16+16<20+16

3p<36

Now divide both sides by 3

3p/3<36/3

p<12

The answer is C


#27

3p-6>21

Just do the same thing

Add 6 to both sides

3p-6+6>21+6

3p>27

Divide both sides by 3

3p/3>27/3

p>9

The answer is B


I really hope that's help and good luck :0
