Answer:
C
Step-by-step explanation:
f(x) = ∛(x-1) has a positive slope everywhere. Graphs A, C, D all have f(x) properly shown.
g(x) = f(-x), so is a reflection of f(x) across the y-axis. Only graph C shows this properly.
First one is arithmetic sequence in disguise
an=a1+d(n-1)
a1=first term
d=common differce
n=which term
so
first erm is 4
common difference is 9-4=5
an=4+5(n-1)
when n=10
4+5(10-1)
4+5(9)
4+45
49
B
3.5, to 6.5, 9.5
aritmetic, increase by 3, first term is 3.5
an=3.5+3(n-1)
10th term
3.5+3(10-1)
3.5+3(9)
3.5+27
30.5
A is49
B is 30.5
A is answer
an=a1+d(n-1)
115+(-8)(14-1)
115-8(13)
115-104
11
answer is B
an=a1+d(n-1)
45+(-3)(10-1)
45-3(9)
45-27
18
C
Answer:
Well the answer to a) is (x - 3)(x + 1) and the answer to b) is (x + 4)(x - 2)
I don't really know how to describe it because I can do factorials in my head like it is nothing.

Answer:
r=-10 Hope this helps! If I could have brainliest I'm trying to level to level up.
Step-by-step explanation:
Let's solve your equation step-by-step.
3+5r=−47
Step 1: Simplify both sides of the equation.
5r+3=−47
Step 2: Subtract 3 from both sides.
5r+3−3=−47−3
5r=−50
Step 3: Divide both sides by 5.
5r/5=-50/5
r=−10
Answer:
r=−10
