Part A) Y cannot be described as a function of x, because in order to be a function, there can only be one input, the x value, for every output, f(x) or the y value. Since the x value, 16, generates two y values, -2 and 2, this cannot be called a function.
Part B)
<span>f(x) = 25x + 16
f(20)= 25(20) + 16
f(20) = 500 + 16
f(20) = 516
This is the total cost, in dollars, of renting the truck for 20 hours. </span>
Answer:
The third option
Step-by-step explanation:
First, write the equation out as 700(0.25)=x and 700-x=y (y being your final answer). 700*0.25 is 175. Now, we subtract 175 from 700. 700-175 is 525. $525 is your final answer, which makes the third option correct. Hope this helps!
Answer:
x=6
Step-by-step explanation:
14-8 equals 6, thos leaves you with x=6
Given:
Roses: 22
Daisies: 12
Carnation: 16
22 + 12 + 16 = 50 flowers in one bouquet
The ratio of the roses to the total number of flowers in the bouquet is 22/50 or simplified to 11/25
Ratio of daisies to carnations is 12:16 or 3:4.
Number of carnations to add to make the ratio into 1:3
12:x = 1:3
12*3 = x
36 = x
36 - 16 = 20 additional carnations.
There must be an additional 20 carnations to make the ratio of daisies to carnation 1:3.
12:36 = 1:3
If you were to simplify your problem it would be 12
Hope i helped, Good Luck!!!!
