Answer:
Additive
-2 = 2
18 = -18
-30 = 30
2/5 = -2/5
Multiplicative
8/9 = 9/8
12/15 = 15/12
-6 = -1/6
10 = 1/10
Step-by-step explanation:
an<em> additive inverse</em> is a number you must add to another number to get 0
(think of it as the negative version of the number)
<em>{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}</em>
-2 + 2 = 0
18 - 18 = 0
-30 + 30 = 0
2/5 - 2/5 = 0
a <em>multiplicative inverse</em> is a number that you multiply by another number to get 1.
We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction
(reciprocal of 2 = 1/2 {remember, 2 is the same thing as 2/1 } ; reciprocal of 1 / 8 = 8)
<em>note: reciprocal is being used interchangeably with multiplicative inverse here</em>
<em />
8/9 · 9/8 = 1
12/15 · 15/12 = 1
-6 · -1/6 = 1 {-6 = -6/1}
10 · 1/10 = 1 {10 = 10/1}
hope this helps!! have a lovely day :)

Answer:
x = 5
Step-by-step explanation:
Given: f(x) = -3x + 19
1. Substitute f(x) = 4 into f(x) = -3x + 19:
⟹ 4 = -3x + 19
2. Add 3x to both sides:
4 + 3x = -3x + 3x + 19
⟹ 3x + 4 = 19
3. Subtract 4 from both sides:
3x + 4 - 4 = 19 - 4
⟹ 3x = 15
4. Divide both sides by 3:
3x ÷ 3 = 15 ÷ 3
⟹ x = 5
5. Check your work:
4 = -3x + 19
4 = -3(5) + 19
4 = -15 + 19
⟹ 4 = 4 ✔
