Find the equation of the line that is perpendicular to y = 2x + 8 A) y =
1
2
x – 4
B) y = –
1
2
x – 4
C) y = 2x + 12
D) y = –2x + 12

Step-by-step explanation:

We are given the line y=2x+8. It is in slope-intercept form or y= mx+b, where m is the slope and b is the y-intercept.

The slope of the line is 2.

We want to find the equation that is perpendicular. Perpendicular lines have negative reciprocal slopes.

1. Negate

2. Reciprocal

The perpendicular slope is -1/2, so the correct equation must be B.

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
