+-(1,7)/+-(1,3,9) are the combinations of f(x)
Use ratios to solve
15 m/8 km = x m/50 km Cross multiply
15(50) = 8x
750 = 8x divide by 8 on both sides
93.75 = x
93.75 miles = 50km
Answer: D: x = {-3, -1, 1}
<u>Step-by-step explanation:</u>
Domain refers to the x-values of the coordinates.
Coordinates are in the form (x, y) so we are looking for the values on the left side of the parenthesis.
(-3, -2) --> x = -3
(-3, 0) --> x = -3 <em>already listed above so no need to list it again</em>
(-1, 2) --> x = -1
(1, 2) --> x = 1
the x-values are: -3, -1, & 1
so the domain is: x = {-3, -1, 1}
Answer: 52. 12000mililiters
53.
You move the decimal point 6 spaces to the right
54. 3,000,000meters
The pattern would be 5,7,12,20,31,45
