Determining the input using an equation f (x) = -1/3x + 7

daser333 [38]

Answer:

Step-by-step explanation:

f(x)=2/3

2/3=-1/3x+7

Subtract 7 from both sides

2/3-7=-1/3x

-6 1/3 = -1/3x

Multiply both sides by -3

-3(-6 1/3)=-1/3x(-3)

19 = x

PLZ ans have mocks plz

Answer:

The table will be:

x |-2 | -1 | 0 | 1 | 2

y | 1 | 4 | 5 | 4 | 2

Step-by-step explanation:

The function is:

$y=5-x^{2}$

a) The x values of the table is:

x |-2 | -1 | 0 | 1 | 2

So, when x = -2, y will be:

$y(-2)=5-(-2)^{2}=5-4=1$

Doing the same with the other x values we have:

$y(-1)=5-(-1)^{2}=5-1=4$

$y(0)=5-(0)^{2}=5$

$y(1)=5-(1)^{2}=5-1=4$

$y(2)=5-(2)^{2}=5-4=1$

The table will be:

x |-2 | -1 | 0 | 1 | 2

y | 1 | 4 | 5 | 4 | 1

I hope it helps you!
