BRAINLIEST!!PLEASE HELP ME!!
pishuonlain [190]

Answer:


Step-by-step explanation:

The truck's fuel consumption is:

660 miles

---------------- = 7.33 miles per gallon.

90 gallons

Draw a set of coordinate axes, with # of gallons on the horiz. axis and distance traveled on the vertical axis.  Place a black dot at (0,0).  Starting at (0,0), draw in scale divisions that can accommodate 0-100 gallons.  Mark scale divisions on the vertical axis such that the maximum distance traveled is 800 miles.  Now draw a vertical line through 90 gallons and a horizontal line through 660 miles.  Draw a black dot where these two lines intersect.  Now draw a straight line through (0,0) and (90,660).  These two points are your intercepts, horiz. first and vert. second.

The domain is the set of numbers on the horiz. axis for which you have a graph (meaning that your function is defined).  Here your domain is

[0,90] gallons.  No function is defined for less than 0 gallons or more than 90 gallons.

The origin represents no fuel yet consumed and no distance yet traveled.

Y = 7/8u + 9, solve for u
vivado [14]

Answer:

u=\frac{8y-72}{7}

Step-by-step explanation:

Flip the equation.

\frac{7}{8}u+9=y

Add -9 to both sides

\frac{7}{8}u+9(-9)=y(-9)

\frac{7}{8}u=y-9

Divide both sides by 7/8

u=\frac{8y-72}{7}

The 1,840 rock concert tickets sold were twice the amount of jazz concert tickets sold
Yuki888 [10]
So there where two times the amount of rock tickets sold than the jazz concert. If that is it then you divide the 1840 by 2 getting 920, dividing 1÷2 you get zero remainder 1, 18÷2= 9, 4÷2= 2, and 0÷2= 0. 920. Hope i helped :)
