Answer:
- 5x² + 6x + 6
Step-by-step explanation:
f(x) - g(x) - h(x)
= 3x + 5 - (4x² - 2) - (x² - 3x + 1) ← distribute parenthesis
= 3x + 5 - 4x² + 2 - x² + 3x - 1 ← collect like terms
= - 5x² + 6x + 6 ← in standard form
Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: 
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.
Answer:
the answer is D because it makes the most sense
Answer: 24m+28
Step-by-step explanation:
you would distribute the -4 threw eveything
so it would be 24m+28
Answer:
7x² + x + 3
Step-by-step explanation:
Step 1: Write expression
(3x² - 2x + 1) + (4x² + 3x + 2)
Step 2: Combine like terms
7x² + x + 3
