Answer:
The answer is 6.
Step-by-step explanation:
Since there is a 5 to the right of the decimal, you will round the number immediately to the left of the decimal up. So the nearest whole number would be 71.
Answer:
y = 3
Step-by-step explanation:
Calculate the slope between the 2 points using the slope formula, then equate to - 3
m = 
with (x₁, y₁ ) = (12, - 12 ) and (x₂, y₂ ) = (7, y )
m =
=
= - 3 ( multiply both sides by - 5 )
y + 12 = 15 ( subtract 12 from both sides )
y = 3
Answer:
1st option.
0 to 100 miles per hour
Step-by-step explanation:
as we can see the question states that a particular car' s gas mileage DEPENDS upon its speed.
Since, the independent variable is the domain of the function the speed of the car will act as the domain of the given function.
out of all the option option 1 gives us values of speed( cause its unit is miles/ hour - unit of speed).
so the domain is
0 to 100 miles per hour.
We have that
y=-2x+3
y=(1/3)x-4
using a graph tool
see the attached figure
the solution of the system is the point (3,-3)
