Answer:
1/2
Step-by-step explanation:
2x+y =4
Lets solve for y so the equation is in slope intercept form
Subtract 2x from each side
2x-2x+y = -2x+4
y = -2x+4
The slope is-2
When we want a perpendicular line, the slope is the negative reciprocal
-(1/-2)
+ 1/2
The slope of the new line is 1/2
Answer:
6 pounds.
Step-by-step explanation:
70-25.36= 44.64 (the amount of money she spent)
44.64/7.44 (per pound cost)= 6
<em>Answer: y=2/3x-2</em>

<em>Step-by-step explanation:</em>
<em>Slope intercept form is: y=mx+b</em>
<em>m=slope</em>
<em>b= y-intercept</em>
<em>slope is </em><em>2/3</em>
Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
= 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
= 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
= 80 + 20
= 100cm
3rd piece = 80 cm - (25% x 80)
= 80 cm - 20
= 60cm
Hope this helps :))
