Answer:

if x = 4, which of the following expressions does not equal 9

Multiple Choice:

A. x-(-5)

B. x+5

C. 2x + 1

D. x-13

<em>Correct answer: D</em>

Step-by-step explanation:

First we have to substitute 4 into X for all the multiple choices ( A to D)

A. x-(-5): first substitute 4 for X we will get:

<u>4 - (-5)</u><u> </u>remember order of operation. this means that we have to work with the parentheses first:  negative times negative equal to positive. so, negative times negative 5 equal to positive five: - (-5) = +5 now we go back to solve the rest of the equaltion

<u>4+5 = 9 </u>which means that answer A is incorrect since the question is asking which expression does NOT equal to 9

B.  x+5

4+5 = 9 the answer B is also incorrect because it's equal to 9

C. 2x+1

2(4) +1: 2 times 4 equal 8 plus 1 equal 9.

D. x-13

4 -13 = <u>-9</u>

Which of the following represents the graph of f(x) = 3x2 - 12 ?
xxMikexx [17]
F(x) = 3x² - 12

Finding where the graph crosses the axes will help us to determine the correct graph

When x = 0,
f(0) = 3(0)² - 12
f(0) = -12

So we have one point (0, -12)

When y = 0
0 = 3x² - 12
12 = 3x²
4 = x²
√4 = x
x = ⁺/₋ 2 

So the graph crosses the x-axis at -2 and 2 and the y-axis at -12

The correct graph is option A
