Answer:
The answer is below
Step-by-step explanation:
a) g(10) = -3(10) + 1 = -30 + 1 = -29
b) f(3) = (3)² + 7 = 16
c) h(-2) = 12 / (-2) = -6
d) j(7) = 2(7) + 9 = 14 + 9 = 23
e) h(a) = 12 / (a) = 12 / a
f) g(b + c) = -3(b + c) + 1 = 1 - 3b - 3c
h) g(x) = 16
-3x + 1 = 16
3x = 1 - 16
3x = -15
x = -5
i) h(x) = -2
12 / x = -2
x = 12 / -2 = -6
j) f(x) = 23
23 = x² + 7
x² = 16
x = √16
x = 4
Answer:
1.1 : C - x^2 + x - 2
1.2 : A - 4a^2 - 6b^2 + 12
Step-by-step explanation:
When we have the expression p(x) - q(x), we can substitute those functions in:
(x^2 + 2x - 5) - (x - 3)
We can distribute:
x^2 + 2x - 5 - x + 3
and then combine like terms(2x & -x, -5 & 3)
x^2 + x - 2
This is the same as C.
We can start by distributing:
a^2 - 2b^2 + 3 - 4b^2 + 5 + 3a^2 + 4
Now, we can combine all the a^2 terms(a^2 & 3a^2):
4a^2 - 2b^2 + 3 - 4b^2 + 5 + 4
Then, we can combine the b^2 terms(-2b^2 & -4b^2):
4a^2 - 6b^2 + 3 + 4 + 5
and lastly, all the constants:
4a^2 - 6b^2 + 12
This aligns with option A
Answer:
C.
Step-by-step explanation:
because it is x-8, it will shift to the right because it is always the opposite of the symbol. +3 refers to the points going up

Step-by-step explanation:
FIRST FOR ORANGES SHE BOUGHT 10 SO 10 TIMES 3 IS 30 AND THEN 11 TIMES 2.40 IS 26.40. 30 PLUS 26.40 IS 56.40 THATS YOUR AWNSER
