ANSWER:
a. y=3x+2
b. y=-1/2x-1
find the y intercepts that fit with the coordinates and for a parallel line the slope stays the same, while for a perpendicular line the slope flips and turns into the opposite symbol.
A) 62 -2t < 40 . . . . . t is time in hours
c) 6+3n ≤ 96 . . . . . . n represents the number
e) 4 +2W < 62 . . . . . . W represents the width of the rectangle
f) 3.50 +0.15p ≤ 5.00 . . . . . p is the number of pencils Miranda buys
A. 12.2%
Steps:
1) 1380-1571= -191
2) -191/1571= -0.12
3) -0.12(100) = 12.15 = 12.2%
Answer
t = 2
Step-by-step explanation
Simplify 5-(t+3).
-t+2=-1+2t-3
Subtract 3 from -1
-t+2=2t-4
Move all terms containing to the left side of the equation.
-3t+2=-4
Move all terms not containing t to the right side of the equation.
-3t=-6
Divide each term by -3 and simply.
t = 2
Answer: The number is 7
Step-by-step explanation:
Let x be the [number]
<u />
<u>Rephrase the expression</u>
2 times a number is increased by 4, it is the same as 25 decreased by the number
2x+4=25-x
<u>Calculate</u>
Given
2x+4=25-x
Add x on both sides
2x+4+x=25-x+x
3x+4=25
Subtract 4 on both sides
3x+4-4=25-4
3x=21
Divide 3 on both sides
3x/3=21/3
x=7
