Answer: E, A, D, C, B
Step-by-step explanation:
First, we need to get y alone. So we will add 7 to the side of the equation that has the 4y in it.
So the first one will be.
<em><u>Add 7 to both sides of the equation.</u></em>
Now the second one is
<em><u>4y = 25 + 7 </u></em>Because what you do to one side of the equation, you do to the other. So we add 7 to 25.
Then the 3rd one will be <u><em>4y = 32 </em></u>because 25+7 is equal to 32. But we still have that 4y on the other side of the equation. So the next equation is 4y = 32.
The second to last step is <em><u>Divide both sides by 4 </u></em>because thats
how you isolate y. So once you divide both sides by 4. You will get 8. Leading you into the next and final step.
<em><u>Y = 8</u></em>
And thats how you do it!
Answer:
$1,407.10
Step-by-step explanation:
1000(1.05)^7 = 1.05^7 ≈ 1.40710 * 1000 = $1,407.10
The function
... y = 1/x
has derivative
... y' = -1/x²
which has no zeros. It is undefined at x=0, the only critical point. The derivative is negative for all values of x, so the function is decreasing everywhere in its domain.
Your function
... y = (x+1)/(x-3)
can be written as
... y = 1 +4/(x-3)
which is a version of y = 1/x that has been vertically scaled by a factor of 4, then shifted 1 unit up and 3 units to the right. Shifting the function to the right means x=3 is excluded from the domain (and the interval on which the function is decreasing).
The critical point is x=3.
The function is decreasing on (-∞, 3) ∪ (3, ∞), increasing nowhere.
Answer:
C
Step-by-step explanation:
Because 3 * 3/6 or 3* 1/2 equals 1.5 or 1 and 1/2 and that is what is shown on the graph!
Hope this Helps!
