Answer:
Alright well all you need to do is use the slope intercept which gives a answer
of Slope: - 4
Y- intercept: 1 Hope this helps :)
Step-by-step explanation:
Answer:
B. -4
Step-by-step explanation:
We want to find x such that f(x)=18.
We need to therefore solve 9x+54=18 forx.
9x+54=18
Divide both sides by 9:
(9x+54)/9=18/9
9x/9+54/9=18/9
Simplify:
x+6=2
Subtract 6 on both sides:
x=2-6
Simplify
x=-4.
So f(-4) should have value 18.
Let's check.
f(x)=9x+54
f(-4)=9(-4)+54
f(-4)=-36+54
f(-4)=18
So the answer is B.
Answer:
20.9 feet
Step-by-step explanation:
<em>The figure attached below can be formed through the information given.</em>
<u>Step 1: Find angle y</u>
<em>All angles of a triangle are equal to 180°</em>
<em>67 + 39 + y = 180</em>
<em>y = 74°</em>
<u>Step 2: Use sin formula to find H</u>
<em>a/sin a = b/sin b</em>
<em>32/sin 74 = b/sin 39</em>
b = 20.9 feet.
The height of the tower is 20.9 feet.

Answer:
3.5 years
Step-by-step explanation:
Each year, Louis earned
$1500×0.035 = $52.50
in interest.
The amount of interest that had been credited to his account at the time of withdrawal was ...
$1683.75 -1500.00 = $183.75
Then the length of time the money had been in the account was ...
$183.75/($52.50/yr) = 3.5 yr
_____
<em>Comment on the problem</em>
We have assumed the account earned simple interest. Given the neatness of the answer, we believe that to be a correct assumption.
