Item 14
POSSIBLE POINTS: 6.67
Spiral Review What is the equation of the line through the points (4, 6), (8, 12), and (10, 15)?

Hint(s): Find the slope and y-intercept of the line that passes through the given points.
Use two points to find the slope. Then use the point-slope formula to write the equation. Finally, solve for y.

y=

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

answer: 5

step-by-step explanation:

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
