C because the x's repeat with the 3 and 3. If the x's repeat it is not a function.
Hope that helps.
Answer:
f(x) = 4x − 12
Step-by-step explanation:
It's not quadratic. It's linear. Each time x increases by 1, f(x) increases by 4. So the slope is 4. The y-intercept (when x=0) is -12. The equation of the line is therefore:
f(x) = 4x − 12
Do 50 multiplied by x = 8. Solve for x.
It would give you .16 which is 16%.
Answer:
92.31 km
Step-by-step explanation:
Combined speed = 50+80
= 130 km/hour
Time = 100/130 = 10/13 hours to collide
Speed × time = distance
distance = 10/13 × 120
= 92.30769231 km
The answer is c because 2+7=9 and 10-2=8 and 9 is greater than 8 so 2+7>10-2
