If it can drive 25 miles on 4 gallons, divide 25/4 to get 6.25mi/gal
then divide 125/6.25 to get 20 gallons

The truck gets 6.25 miles per gallon of gas
6.25 x 20 = 125 miles
the answer is C. 20 gallons

PLZ HELP ASAP ON 3 A B AND C

viktelen [127]

A: From the graph, car B was traveling faster.

Because the line of car B is more steep than the line of car A.

B:
The lines cross at (2,80), this means that the two cars were traveling at the same distance (80 miles) at the same time (2 hours).

C:
Since the line passes through the points (0,0) and (2,80)

So the unit rate or slope is 40 mph.

The distance which car A traveled in the first four hours = 4x40= 160 mph

Answer:

3.6 mph

Step-by-step explanation:

The total distance was 6 mi. and the total time was 5/3 hr.

6 ÷ 5/3 = 6(3/5) = 18/5 = 3.6 mph

The slope-intercept form given (6,-5) & perpendicular to -5x - 7y = -17.

tatuchka [14]

Answer:

$y=\dfrac{7}{5}x-\dfrac{67}{5}$

Step-by-step explanation:

Slope-intercept form of a linear equation:

$y=mx+b$

where:

m is the slope.
b is the y-intercept.

Rearrange the given equation so that it is in slope-intercept form:

$\implies -5x-7y=-17$

$\implies -7y=5x-17$

$\implies y=-\dfrac{5}{7}x+\dfrac{17}{7}$

Therefore, the slope of the given equation is -⁵/₇.

If two lines are perpendicular to each other (at right angles), the product of their slopes will be -1. Therefore, their slopes will be negative reciprocals of each other.

Therefore, the slope of the line perpendicular to the given equation is:

$\sf m=\dfrac{7}{5}$
