His work should have looked like this.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10 When he added in both sides, he subtracted 10 from 10,
5x = 20 instead of adding 10 from 10 to make 20.
x = 4
2(4) + y = 5
8 + y = 5
y = -3
The correct answer for this question is this one: "<span>y = -x + 2"</span>
<span> y - intercept = (0,2) slope = -1
y = mx + b
2 = -1 (0) + b
b = 2
so the equation of the line is
<u>y = -x + 2</u></span>
Hope this helps answer your question and have a nice day ahead.
Answer:
area=6
perimeter=36
Step-by-step explanation:
Since it takes 48 minutes to walk 6 laps, you can divide 48 by 6 to get how long it takes for him to walk one lap. Mickey will take 8 minutes to walk 1 lap.
48÷6=8
