Answer: Yes we have a direct proportional relationship</h3><h3>constant of proportionality = 8</h3>
equation is y = 8x
=============================================
Explanation:
Divide each x and y pair like so: y/x
If we get the same result each time, then we have a direct proportion.
y/x = 32/4 = 8
y/x = 56/7 = 8
y/x = 96/12 = 8
Each time we get the same result 8, which is the constant of proportionality. The table does show a direct proportional relationship. The equation is y = 8x which is in the form y = kx. The k value is the constant of proportionality. So k = y/x.
Answer:
f (x) = 2.3x grows the value of x at faster rate
she saved $3, and we know the discount is 15%, so her savings is that 15%, thus we know 15% of that purchase is 3.
let's say the full price is x, and therefore the 100%, if we know 3 is the 15%, what is x?
Answer:
x= -7
Step by Step Explanation:
We can write them both like functions like this
A= 5x- 4
B= 3x+ 8
The output of A will be three times the output of B
A=3b
We replace with the functions
5x-4= 3
We solve for x
5x= -4= 9x + 24
5x- 9x= 24 + 4
-4x= 28
x= 28 - 4
x= -7
The output that makes the out put of A 3 times the output of B is -7
