Answer:
y = 6x
Step-by-step explanation:
To write an equation, find the unit rate or constant of proportionality (k).
Using a point on the line, (3, 18):
Constant of proportionality, k = y/x = 18/3
k = 6
To write an equation, substitute k = 6 into y = kx.
Thus:
y = 6x
Answer:
Step-by-step explanation:
complementary angles add up to 90
so if one angle is 67.89, then the other angle is : (90 - 67.89) = 22.11 <==
Answer:
Pyramid A is 20.40 times smaller than pyramid B.
Step-by-step explanation:
It is given surface area of pyramid A is
Surface area of pyramid B is
We have to find that how many times pyramid A is smaller than pyramid B
For this we have to divide surface area of pyramid B by surface area of pyramid A
Therefore ,
So pyramid A is 20.40 times smaller than pyramid B.
Answer:
m= 2/3
Step-by-step explanation:
m= rise/ run
Because you have a visual, the easiest way would be to count units up over units to the right.
Starting from (-2, 0) and going to (1, 2) that is 2 units up and 3 units to the right. It also cannot be simplified further.
Answer:
$40
Step-by-step explanation:
If you were to purchase 7 picture frames, you would replace x in the equation with 7, this is shown below.
<u>f(x)=9x-23 ---> f(x)=9(7)-23</u>
Now we can solve for f(x). First start with 9(7).
<u>f(x)=9(7)-23 ---> f(x)=63-23</u>
Now finish the last part by subtracting 23 from 63.
<u>f(x)=63-23 ---> f(x)=40</u>
This means that you would have to pay $40 dollars to purchase the 7 picture frames.
