MARKNING BRAINLEST ! :) * The table shows a linear function, find the values of A , B , & C. Show your work.
lawyer [7]

Answer:

A = 11, B = 25/3, C = -1

Step-by-step explanation:

A linear function has the form:

f(x) = ax + b

(1)

f(3) = 8a + b = 8

f(5) = 5a + b = 9

Using the last 2 equations we can solve for 'a' and 'b'.

8a + b = 8 | 5a + b = 9

We multiply the second one by -1:

8a + b = 8 | -5a -b = -9

And then we add them together:

3a = -1

a = \frac{-1}{3}

We then solve for 'b':

5a + b = 9

5(-1/3) + b = 9

b = 9 + 5/3

b = 32/3 = 11\frac{1}{3}.

We then use this to find A, B, C.

f(x) = (-1/3)x + 32/3

(2)

f(A) = -A/3 + 32/3 = 7

\frac{-A}{3} + \frac{32}{3} = 7\\A - 32 = -21\\A = 11

(3)

f(7) = -7/3 + 32/3 = B

25/3 = B

(4)

f(C) = -C/3 + 32/3 = 11

\frac{-C}{3} + \frac{32}{3} = 11\\C - 32 = -33\\C = -1

Solve the inequality for x.
LiRa [457]

The solution to the inequality x-13<=7+4x is x >= -20/3

<h3>How to solve the inequality?</h3>

The inequality expression is given as:

x-13<=7+4x

Add 13 to both sides of the inequality

x <= 20 + 4x

Subtract 4x from both sides of the inequality

-3x <= 20

Divide both sides of the inequality by -3

x >= -20/3

Hence, the solution to the inequality x-13<=7+4x is x >= -20/3
