Answer:
D. 21 ft
Step-by-step explanation:
We need to use Power of Points, which basically says that for intersecting chords in a circle (see attachment), a * b = c * d.
Here, we can say that a = x, b = 6, c = 7, and d = 18. Then, we have the equation:
ab = cd
x * 6 = 7 * 18
6x = 126
x = 21
Thus, x is 21 ft.
Hope this helps!
Answer:
No this is not a function.
Step-by-step explanation:
This is not a function because some of the x-values repeat, which is not how a function works. For this to be a function, each x-value would have to be different. In this case, the 4 and 5 repeat in the x-values.

Answer:
They changed 5m into a positive when it should've stayed as a negative until you isolate the variable m at the end, making m actually equal -7.
Step-by-step explanation:
-5m - 16 = 19
-5m = 19 + 16
-5m = 35
m = 35/-5
m = -7

<u>7 gallons were used for city driving and 17 gallons were used for highway driving</u>
Correct statement and question:
camison's minnan gets 14 miles per gallon for city driving and 19 miles per gallon for highway driving. At the beginning of the week, the 24-gallon tank was full. The family traveled 421 miles before running out of gas. How many gallons were used for city driving and how many were used for highway driving?

Previous question found at brainly
Step-by-step explanation:
x = Gallons for city driving
24 - x = Gallons for highway driving
Miles drove before running out of gas = 421
Now let's solve for x, writing the following equation:
14x + 19 (24 - x) = 421
14x + 456 - 19x = 421
-5x = 421 - 456
-5x = - 35
x = -35/-5
x = 7 ⇒ 24 -x = 17
<u>7 gallons were used for city driving and 17 gallons were used for highway driving</u>
