Answer: x=2
Step-by-step explanation:
first subtract 3x from both sides
then your equation will be 8x-7=9 then you will add 7 to both sides getting 8x=16 then divide both sides by 8 and x=2
Answer:12.8
Step-by-step explanation:
Answer:
simplify -1(3/5)÷(-2/3) = 9/10
=90/100
= .90 and there's your answer
<h2>
Answer:The graph of

is the graph of

compressed vertically.</h2>
Step-by-step explanation:
Given that
and 
is always positive because
is always positive.
is always positive because
is always positive.
So,both are always positive.
So,there is no flipping over x-axis.
In
,the height of a point at
is 
In
,the height of a point at
is 
So,height of any point has less height in
than 
So,the graph of
is the graph of
compressed vertically.
In this problem we need to find the value of a and b. So given that t<span>he function should be in the form f(n) = an + b and we know each value of n, then out goal is to find a and b.
For getting this purpose, we need to find a system of two equations (given that we have two unknown variables)
Therefore:
(1) f(0) = a(1) + b = 18
</span>∴ a + b = 18
<span>
(2) f(1) = a(2) + b = 24
</span>∴ 2a + b = 24<span>
Solving for a and b we have:
a = 6
b = 12
Finally:
f(n) = 6n + 12</span>
