Remark
The way this is written I would assume that it means 4*f(x) = x. That may not be entirely the correct assumption to be made.
Step One
Replace f(x) by 4f(x)
4*f(x) = x
Step two
Divide both steps by 4
f(x) = x/4 or (1/4)x
The slope is now 1/4
Discussion
A is incorrect.
The slope has been changed.
B is incorrect
The slope has been changed to 1/4 and the y intercept is still 0
C looks to be the right answer.
D The y intercept is still zero.
Comment
The question is a little hard to interpret. I've read it literally. That means that I have taken the question to mean that only f(x) was altered. If however, the right side was multiplied by 4 as well (as should be done), then the answer is A same slope same intercept. That's because the 4s on the left and right cancel, and the original equation results. I'm going to pick C but don't be surprised if it is A
C <<<<<answer
When you see questions with dirrerent scales, find the scale factor first.
Scale factor
= A ÷ A’ = 12 ÷ 4 = 3
Larger flag perimeter = 3 × 16 = 48 units
The unit rate in the equation is 20.
Option C) is the correct answer.
<u>Step-by-step explanation</u>:
Step 1 :
In the given equation y = 20x
where,
x ⇒ total number of hours for tutoring
20 ⇒ the cost per hour of tutoring
y ⇒ the total cost for total hours of tutoring
Step 2 :
Unit rate refers to the value per hour.
Here, the cost for 1 hour of tutoring is $20.
∴ The unit rate is $20 per hour of tutoring.
Answer:
It will take 554 years
Step-by-step explanation:
Here, we want to estimate the time when t will be $50
We can rewrite the exponential equation as;
y = 200(1-0.0025)^t
In this case, y = $50 and we want to calculate t
so, we simply proceed to substitute the value 50 for y
we have this as ;
50 = 200(1-0.0025)^t
50/200 = (1-0.0025)^t
1/4 = 0.9975^t
0.25 = 0.9975^t
Take the natural logarithm of both sides
ln 0.25 = ln 0.9975^t
ln 0.25 = t ln 0.9975
t = ln 0.25 / ln 0.9975
t = 553.8 = 554 years
The bike will be $50 in 554 years
Answer:
1 x 1 = 1.
6 x 1 = 6cm^2
multiply by 6 cause 6 faces
