10=a/2 + 7
First subtract 7 from both sides
3=a/2
Next multiple 2 on both sides, so that a is by itself
3(2)=a
A=6
Answer:
-1/8
Step-by-step explanation:
Perpendicular slopes are negative reciprocals
The slope of y=8x+5 is 8, because it is in slope intercept form: y=mx+b form, where m is the slope.
Negative:
8/1--> -8/1
Reciprocal:
Flip the numerator and denominator
-8/1--> -1/8
So, the perpendicular slope of 8 is -1/8
Well, if y = x - 5, then we calculate:
when x = -1 then y = -1 -5 = -6
when x = 0 then y = -5
when x = 1 then y = 1 - 5 = -4
when x = 2 then y = 2 - 5 = -3
Hope this helps!
