Answer:
Step-by-step explanation:
The constant of proportionality is usually presented as the variable k. It is usually written as:
f(x) = kx
where f(x) means a function of x. It can also be another variable, for example, y,
We test each pair to find k,
24 = 6k
k = 24/6 = 4
72 = 18k
k = 72/18 = 4
216 = 54k
k = 4
648 = 162k
k = 4
Thus, the answer is A. yes and k=4.
So the way you would find it is a ratio.
1.
![\frac{6}{2.5} \frac{x}{17}](https://tex.z-dn.net/?f=%20%5Cfrac%7B6%7D%7B2.5%7D%20%20%20%20%20%5Cfrac%7Bx%7D%7B17%7D%20)
2. =(6)(17)/(2.5)
3. =102/2.5
4. =40.8
So the building would be 40.8 feet tall.
Answer:
True
Step-by-step explanation:
we know that
The opposite sides of a parallelogram are parallel and the length of their sides is equal.
step 1
<em>Find the slope of each side</em>
we know that
If two lines are parallel then their slopes are the same
The formula to calculate the slope between two points is equal to
we have
<em>one side</em>
Substitute the values
<em>opposite side</em>
Substitute the values
compare
m1=m2
therefore
both lines are parallel
step 2
Find the distance
the formula to calculate the distance between two points is equal to
we have
<em>one side</em>
Substitute the values
<em>opposite side</em>
Substitute the values
Compare
d1=d2
Both sides have the same length
so
1) Both lines are parallel
2) Both sides have the same length
therefore
The statement is True
Answer:
5a -12
Step-by-step explanation:
-7a - 8 + 12a - 4
Add the terms that have the variable "n"
5a - 8 -4
add numbers
5a-12
