Answer: The graph does not show two quantities that vary directly, because the line does not pass through the origin.
Step-by-step explanation:
By definition, you know that Direct variation equations have the following form:
Where "k" is the constant of proportionality.
The equation means that when "x" increases, "y" increases" and the ratio does not change.
Now, it is very important to remember the following:
- The graph of a Direct variation equations is a line whose slope is "k".
- The line must passes throug the origin (
)
Observe the graph provided.
As you can notice, the line does not pass through the origin; therefore, that graph does not show two quantities that vary directly.
2c+3c that would be 5c
add 6 to both sides and you'll get 20
divide 20 by 5
and c=4
Answer:
5 + x + 5 + x + x
Step-by-step explanation:
We are given 4 expressions and we have to determine which expressions shows a sum of five terms.
We use the process of elimination:
5(x + 5)
=5x+25 (distributing 5)
This contains sum of only two terms, <u>eliminate</u>.
5x
It contains only 1 term, <u>eliminate</u>.
5 + x + 5 + x + x
It contains 5 terms 5,x,5,x and x, <u>KEEP</u>!
5.
Only contains 1 term, <u>eliminate</u>.
With this said, were left with:
5 + x + 5 + x + x
Which is the correct answer! :)
Answer:
152 in^2
Step-by-step explanation:
If you take the left side and consider it a whole rectangle, you can calculate the area of that triangle to be 80. Using the same method, you can find the area of the rectangle of the right to be 72. Then add them together.
80 + 72 = 152 in^2
