After 4 minutes of reading, Aaron was on page 14 of his book. After 8 minutes he was on page 20. Which equation models the page number, y in terms of minutes x? A. y=-8x+1.5
B. y=1.5x+8
C. y=8x+1.5
D. y=-1.5x+8

  B.  y = 1.5x +8

Step-by-step explanation:

You can try x=4 in the various equations to see which gives the right value (14).

__

A: y = -8(4) +1.5 = -30.5

B: y = 1.5(4) +8 = 14 . . . . . . . . .  this equation works

C: y = 8(4) +1.5 = 33.5

D: y = -1.5(4) +8 = 2

__

Alternatively, you can use the 2-point form of the equation of a line to write the equation:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (20 -14)/(8 -4)(x -4) +14 . . . . fill in (x1, y1) = (4, 14); (x2, y2) = (8, 20)

  y = 1.5(x -4) +14 . . . . . simplify somewhat

  y = 1.5x +8 . . . . . . . . write in slope-intercept form

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
