Avery needs a total of $12.75 in quarters at the local laundromat. She has already saved
$3.25. Which equation and solution process
can be used to determine q, the number of
additional quarters Avery needs to wash her
laundry?
A) 12.75 = 5 + 3.25
Sub
tract 3.25 from both sides and multiply
the difference by 25.
B)3.25 -0.259 = 12.75
Subtract 3.25 from both sides and divide
the difference by -0.25.
I
C)12.75 = 0.259 + 3.25
Subtract 3.25 from both sides and divide
the difference by 0.25.
D) 259 + 3.25 = 12.75.
Subtract 3.25 from both sides and divide
the difference by 25.

In a two-digit number the units' digit is 7 more than the tens' digit. the number with digits reversed is three times as large as the sum of the original number and the two digits. find the number.

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
