Help if you can if not that’s fine

c.

Step-by-step explanation:

in table one they are adding two to the value of x

in table two they are multiplying x by 4

Both table shows additive relationship.

Step-by-step explanation:

look at the y relationship on each graph to determine which relationship

table 1: you add 1 to the y values

3 + 1 = 4

4 + 1 = 5

5 + 1 = 6

table 2: you add 4 on the y values

4 + 4 = 8

8 + 4 = 12

12 + 4 = 16

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
