Answer:
3
Step-by-step explanation:
f(1)=−3
f(n)=2⋅f(n−1)+1
f(2)= 2×1(2-1)+1
= 2×1+1
= 2+1
= 3
Distribute
x-12x+30=-x-4
Combine like terms
-11x+30=-x-4
Add x to both sides
-10x+30= -4
Subtract 30 from both sides
-10x=-34
Divide both sides by -10
x=3.4
Final answer: x=3.4
A is 9 for the proportion part but I can’t see the rest of b so I can’t answer that for you
Hey there! :)
Answer:
2nd choice.
Step-by-step explanation:
Given:
630 = 42f.
Divide both sides by 42 to solve for f:
630/42 = 42f/42
f = $15.
This equation is not an inequality, so a line would not be graphed on the number-line. The proper way to show a single solution would be with a point. Therefore:
The second choice is correct. The number line has a single point at f = 15.
