Answer:
Step-by-step explanation:
From the given table,
A. The unit rate for each car is,
Car A = 
= 32 miles per gallon
Car B = 
= 34 miles per gallon
Car C = 
= 35 miles per gallon
Car D = 
= 31 miles per gallon
B. From the derived values in A, the car that uses the least amount of gas is Car C.
C. Total distance covered = 496 miles x 4
= 1984 miles
The gallons of gas the Car A would need for the journey can be determined by;
Car A requires 1 gallon for 32 miles
So that for 1984 miles = 
= 62 gallons
Car A would need 62 gallons of gas to make the trip.
D. Amount spent on gas for Car A = $2.12 x 62
= $131.44
E. speed = 
⇒ time = 
Given the for Car A, speed = 68 miles per hour.
time = 
= 29.1765
time = 29 hours
It would take approximately 29 hours for Car A to cover the total distance of 1984 miles.
Answer:
-0.25 or -1/4
Step-by-step explanation:
Remember slope is : change in y's over change in X's
Easy
the equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
find slope
slope between (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
given
(9,0) and (-7,-4)
slope=(-4-0)/(-7-9)=-4/-16=1/4
slope os 1/4
a point is (9,0)
x1=9
y1=0
y-0=1/4(x-9)
we can put it into slope intercept and standard form
slope intercept
y=(1/4)x-(9/4)
standard
minus 1/4x
-1/4x+y=-9/4
times -4
x-4y=9
I believe the correct answer is false. Quadratic equations that can be solved using the quadratic formula cannot always be solved by factoring. <span>Not </span>all quadratic equations can<span> be </span>solved by factoring<span>. Another method that can be used is completing the square. Hope this answers the question.</span>
Equation of line is y=mx+b where m is the slope and b is the y-intercept.
slope=6/5
y-intercept=1
equation: y=6/5x+1
