Answer:

6(2a-a+1)=24 =(3)

4+3(a+2)=16 =(2)

3a-2a-4=0 =(4)

2a+3(a+1)=8 =(1)

Step-by-step explanation:

6(2a-a+1) =24

6(2a-a+1) =2412a-6a+6 =24

6(2a-a+1) =2412a-6a+6 =246a =24-6

6(2a-a+1) =2412a-6a+6 =246a =24-66a= 18

6a/6= 18/6

a = 3

4+3(a+2)=16

4+3a+6=16

3a+10=16

3a=16-10

3a=6

3a/3=6/3

a=2

3a-2a-4=0

a-4=0

a=0+4

a=4

2a+3(a+1)=8

2a+3a+3=8

5a+3=8

5a=8-3

5a=5

5a/5=5/5

a=1

Select the ordered pair that represents a solution to each function below. f(x) = -x^2 +5

sweet [91]

Answer:

Factored: - ( x - 5 )( x + 1 ) X - Intercepts: (5, 0) and (-1, 0)

Step-by-step explanation:

f(x) = -x^2 +5

Factor:

-x^2 + 5

- ( x - 5 )( x + 1 ) = 0

-x + 5 = 0 -x - 1 = 0

-x = -5 -x = 1

-x/-1 = -5/-1 -x/-1 = 1/-1

x = 5 x = -1

X - Intercepts = (5, 0) and (-1, 0)

Y - Intercepts = (0, 5)

Christopher made 3 1/4 dozen cupcakes. He added vanilla icing to 1/3 of the cupcakes and added chocolate icing to the rest. How

Arada [10]

1 dozen = 12

First you would multiply.

3.25 x 12 = 39 cupcakes total
1/3 x 12 = 4 cupcakes with vanilla icing

Then you subtract.

39 - 4 = 35 cupcakes with chocolate icing

Then to get the answer back in to terms of dozens, divide by 12.

35/12 = 2 11/12

Hope this helped
