Answer:

Option A is correct.

1+ \frac{2}{5}x

Step-by-step explanation:

Simplify:   2 + \frac{3}{5}x - 1 - \frac{1}{5}x

Like terms are those terms which have same variables to the same power.

Combine like terms;

(2-1) + (\frac{3}{5}x -\frac{1}{5}x)

1+ (\frac{3-1}{5}x)

Simplify:

1+ \frac{2}{5}x

Therefore, the simplified expression of  2 + \frac{3}{5}x - 1 - \frac{1}{5}x is, 1+ \frac{2}{5}x

Option C:

f(x) = 5x + 7 is the function of the input-output table.

Solution:

Option A: f(x) = 6x + 9

Input x = 1 in the above equation.

f(1) = 6(1) + 9

    = 6 + 9

f(1) = 15

But the output is 12 in the table.

So, it is not the function of the table.

Option B: f(x) = 7x + 5

Input x = 1 in the above equation.

f(1) = 7(1) + 5

f(1) = 12

Input x = 5 in the above equation.

f(5) = 7(5) + 5

f(5) = 40

But the output is 32 in the table.

So, it is not the function of the table.

Option C: f(x) = 5x + 7

Input x = 1 in the above equation.

f(1) = 5(1) + 7

f(1) = 12

Input x = 5 in the above equation.

f(5) = 5(5) + 7

f(5) = 32

Input x = 10 in the above equation.

f(10) = 5(10) + 7

f(10) = 57

Input x = 5 in the above equation.

f(15) = 5(15) + 7

f(15) = 82

All outputs are correct for the given input.

Hence it is the function of the table.

Option D: f(x) = 12x + 1

Input x = 1 in the above equation.

f(1) = 12(1) + 1

f(1) = 12

Input x = 5 in the above equation.

f(5) = 12(5) + 1

f(5) = 61

But the output is 32 in the table.

So, it is not the function of the table.

Hence Option C is the correct answer.

f(x) = 5x + 7 is the function of the input-output table.

Please Help: Determine which ordered pair is NOT a solution of y = -5x - 4
777dan777 [17]
It's A.
All you need to do is plug in the X from the ordered pair, then solve.

y=-5x-4
y=-5(10)-4
y=-50-4
y=-54
Which is NOT -52, so the answer is indeed A
