Answer:
11
Step-by-step explanation:
1) lets get rid of the parentheses, we dont really need them:
−22 −4 + 8+ 52 + 2 − 25
Following order of operations we need to work from left to right
so
-22-4=-26
-26+8=-18
-18+52=34
34+2=36
36-25=11
the answer is 11
hope this helps
25-18=7
50+7=57
86-57=29
She started with 29 dollars
Check your work:
29+25=54
54-18=36
36+50=86
(3,5) is point B, hope this helped :))
Answer:
f(x) + g(x) = -9x³ - 14x² + 2x + 7
Step-by-step explanation:
This notation (f + g)(x) just wants you to add the two functions; it's the same thing as writing f(x) + g(x).
f(x) = -6x² + 9x + 7
g(x) = -9x³ - 8x² - 7x
All you have to do now is combine like terms and simplify.
f(x) + g(x) = (-6x² + 9x + 7) + (-9x³ - 8x² - 7x)
f(x) + g(x) = -6x² + 9x + 7 + -9x³ - 8x² - 7x
f(x) + g(x) = -9x³ - 8x² - 6x² + 9x - 7x + 7
f(x) + g(x) = -9x³ - 14x² + 2x + 7
