The table below would represent a proportional relationship except for one y-value. Identify which y-value prevents the table fr
om representing a proportional relationship. Then, select the value that would make the table proportional.
X 1.5, 2, 4, 4.5, 7
Y 6, 8, 16, 16.5, 28
Alternative values 17, 18, 18.5, 19.5, 20
1 answer:
9514 1404 393
Answer:
non-proportional y-value: 16.5
corresponding proportional y-value: 18
Step-by-step explanation:
Each y-value is 4 times the corresponding x-value except for (x, y) = (4.5, 16.5).
The correct proportional values would be (4.5, 18).

Just count the number of zeros:
Step-by-step explanation:
There are 4 zeros, so the answer is 5 x 10^4.
Answer:
x=12.5
Step-by-step explanation:
x=2 1/2 times 5
x=12.5
2/80 is equivalent
you can also just multiply the numerator and denominator to find out what else is equivalent.
F(x) = -3x + 7
y = -3x + 7
x = -3y + 7
-3y + 7 = x
-3y = x - 7
y = -1/3x + 7/3
f^-1(x) = -1/3x + 7/3
Answer:
The answer is x=5 and x=−5
x² - 25 = 0
(x-5)(x+5)=0
x²-5x+5x-25=0
x-5=0 x+5=0
x=5 or x=-5
