Answer:
I think the answer is c but I didn’t simplify bc I don’t know what you mean
Step-by-step explanation:
1) it's a function 2) for each number 3) set a input and set b output
to be a function, no ordered pairs should have same first coordinate, hence this is a function
Answer:
16 = 2x
Step-by-step explanation:
The pattern for a direct variation equation is y = kx
y is the "output" or result
k is the "constant" a number that doesn't change in the equation.
x is the "unknown" variable that makes the output of the equation true when found.
Here x=8
16 = 2(8)
Answer:
A) She must have used 20% from the $40 instead of the unknown price.
B) No, because: see below explanation.
Step-by-step explanation:
X is the original price.
If $40 is 80% of x, to find 1% of the price, divide $40 by 80.
You will get $0.50 for 1%.
To find the full amount, just multiply that by 100.
0.50*100= 50.
Total: $50.
Hope this helped!
