Answer:
Ivory is not correct.
Step-by-step explanation:
Ivory is not correct because of the way the first equation is treated. Ivory thinks 2x+2 can be double of what x+1 is. However, x can be anything, even 0. If we replace x with 0 in 2x+2, that would leave 2x = 0, and adding 2 would equal 2. If we look at x+1, we can add 1 to x and would equal 2. So Ivory is not correct, there is many equations other than this one that can equal.
Answer:
(f - g)(x) = -x + 8
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 1
g(x) = 3x - 7
(f - g)(x) = f(x) - g(x)
<u>Step 2: Simplify</u>
- Set up: (f - g)(x) = (2x + 1) - (3x - 7)
- Distribute -1: (f - g)(x) = 2x + 1 - 3x + 7
- Combine like terms: (f - g)(x) = -x + 8
Question: 2{4x - 3(x + 5) + 10} + 3(x - 2)
Steps
1. Expand 4x - 3(x + 5) + 10 = x - 5
= 2(x - 5) + 3(x - 2)
2. Expand 2(x - 5) = 2x - 10
= 2x - 10 + 3(x - 2)
3. Expand 3(x - 2) = 3x - 6
= 2x - 10 + 3x - 6
4. Then, simplify:
Add 2x + 3x = 5x
Add -10 - 6 = -16
5. Plug it in:
5x - 16 <-------------- Answer
Hope this helped!!!!
Answer:
B
Step-by-step explanation:
107 and y form a straight angle and are supplementary, thus
107 + y = 180 ( subtract 107 from both sides )
y = 73
The sum of the interior angles of a quadrilateral = 360°
Sum the given angles and equate to 360
117 + 79 + 73 + x = 360, that is
269 + x = 360 ( subtract 269 from both sides )
x = 91
Thus x = 91, y = 73 → B
