f(x) = 8x-9
f(4)
let x=4 and substitute in
f(4) = 8*4 -9
f(4) = 32-9
f(4) = 23
<h3>By Associative property of multiplication,</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
We have to use the associative property of multiplication
<em><u>Associative property of multiplication</u></em>
When we are multiplying two or three numbers, it does not matter where we put the parenthesis, it results in same answer
Therefore,
Thus associative property of multiplication is used to find solution
<span>We define
day--------------------------X
hockey cards away ------------f(X)
</span><span>He gives 2 cards away ----------------on day 1----------f(X)=2 X=1
</span>He gives 4 cards away ----------------on day 2----------f(X)=4 X=2
He gives 8 cards away ----------------on day 3----------f(X)=8 X=3
the sequence of cards away 2,4,8,16,32,64,128,256,512,1024
f(x) = 2**(x)
The answers are
D <span>Each day corresponds to a unique amount of hockey cards in this sequence.</span>
And B <span>The graph of this sequence would pass the vertical line test.
Each element of the Domain (X = day), relates to a single value of f(x) = number of hockey cards
That is, every value of X must have only one corresponding value of f(x)
(One value of y, for each input X)
This can also be checked by using the vertical line test.
If we plot f(x) and we draw vertical lines in the curve, we can verify that at every input the line intersects only one point of f(x)</span>
Answer:
the answer is
Step-by-step explanation:
3/11
the formula is y2-y1 / x2-x1
Let's solve your equation step-by-step.2m−13=−8m+27
Step 1: Add 8m to both sides.2m−13+8m=−8m+27+8m10m−13=27
Step 2: Add 13 to both sides.10m−13+13=27+1310m=40
Step 3: Divide both sides by 10.10m10=4010m=4
Answer:<span>m=4</span>
