For #3, you just have to plug in the numbers for x.
It tells you what to substitute for x in the question. (x = 0, 1, 2, 3, 4, 5, and 6)

For example, let's substitute 0 for x.
6x - x² (the 2 means square the number, or multiply it by itself)
6(0) - (0)²
0 - 0
= 0.

You'll do that to all the numbers (1-6) and fill out the table.

For #4, you have to solve using the distributive property to find out if the equations on both sides are equal.

I'll do the first one for you.

6a - 8 = 2 (3a - 5)
6a - 8 = 6a - 10
They're not equal.

F f(x) = - 4x + 3 and g(x) = 3x2 + 2x - 4, find (f+ g)(x).

Alla [95]

Answer:

A.

${ \bf{(f + g)x = {(3x}^{2} + 2x - 1) + ( - 4x + 3) }} \\ = ( {3x}^{2} - 2x + 2)$

For which inequality would x = 8 not be a solution?4x + 3 > 09x - 5 < 100x + 4 ≤ 1072 ÷ x ≥ 4

galina1969 [7]

Given:

Given the inequalities:4

$\begin{gathered} 4x+3>0 \\ 9x-5$

Required: Identify the inequality in which x = 8 is a solution.

Explanation:

Substitute 8 for x in each inequality and check whether it satisfies the inequality.

Consider 4x + 3 > 0.

$4\cdot8+3=35>0$

So, x = 8 satisfies the inequality 4x + 3 > 0.

Consider 9x - 5 < 100.

$9\cdot8-5=67$

So, x = 8 satisfies the inequality 9x - 5 < 100.

Consider x + 4 ≤ 10.

$8+4=12>10$

So, x = 8 not satisfies the inequality.

Consider 72 ÷ x ≥ 4.

$72\div8=9\ge4$

So, x = 8 satisfies the inequality.

Final Answer: The inequality in which x = 8 is not a solution is x + 4 ≤ 10.
