Question

Use the table to work out the values of a , b , c , and d .​

Answer 1

Answer:

a = 10, b = 6, c = 2, d = 0

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate

x = - 3 : y = 4 - 2(- 3) = 4 + 6 = 10 → a

x = - 1 : y = 4 - 2(- 1) = 4 + 2 = 6 → b

x = 1 : y = 4 - 2(1) = 4 - 2 = 2 → c

x = 2 : y = 4 - 2(2) = 4 - 4 = 0 → d

Answer 2

Answer:

Just a cheerful teen willing to help,

stay salty...

Step-by-step explanation:

a=10

Substitute for x

y=4-2(-3)

y=4--6

y=4+6

y=10

b=6

Substitute for x

y=4-2(-1)

y=4--2

y=4+2

y=6

c=2

Substitute for x

y=4-2(1)

y=4-2

y=2

d=0

y=4-2(2)

y=4-4

y=0
