Answer:
f(-2) = -1
Step-by-step explanation:
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
Answer:
hour
Step-by-step explanation:
Let x represent time taken by dog to run the 1 and three tenths -mile state fair race.
We have been given that a dog won a race at the local fair by running 3 and one fourth miles in exactly 2 hours.
We will use proportions to solve our given problem as:
We will equate both speeds as:
Cross multiply:
Therefore, it will take hour to complete mile state fair race.

Answer:
Step-by-step explanation:
The given circle is centered at the origin;
The radius of the circle is
units.
You could also count the boxes from the center to any of the given points to get the radius.
The equation of a circle centered at the origin is given by;
We substitute the radius to obtain;
The required equation is
You need to combine -5x and 5x together and that would give you zero so you need to combine 2y and -8y which would give you -6y so the answer is C. -6y
