The line through that point and the origin has a slope of -1. It is perpendicular to the line you want, so the line you want has slope +1. Its equation can be written as
.. y = (x -4) -4
or, in standard form
.. x - y = 8
Answer:
Step-by-step explanation:
4x+2=5x-6
4x-5x=-6-2
-x=-8
therefore, x=8
Answer:
D
Step-by-step explanation:
Neither the table and the graph is correct.
1/4=0.25 miles
5/0.25=20 laps
José has to run 20 laps to run 5 miles.
2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
