Answer:
Step-by-step explanation:
3x+4y=29 .......(1)
6x+5y=43 .......(2)
Multiply equation (1) by 2
6x + 8y = 58......(3)
Substracting (2) from (3)
8y - 5y = 58 - 43
3y = 15
Dividing by 3
3y/3 = 15/3
y = 5
Substituting y = 5 into (2)
6x+5y=43
6x + 5(5) = 43
6x + 25 = 43
6x = 43 - 25
6x = 18
Dividing by 6
6x/6 = 18/6
x = 3
i think it is because...
the slope of line b is slightly steeper than the slope of line a.
hope this helps!
Answer:
so the answer would be A. 7/5x +2
if you try graphing all the other equations it would be either over the picture or just not in the right place.
Answer:
y-2= 1/8(x+8)
Step-by-step explanation:
First, you must find the slope of the line. If it is perpendicular to a line with a slope of -8, the slope must be 1/8. A perpendicular slope means the opposite inverse slope, meaning you switch the numerator and denominator and you switch it from negative to positive.
Second, you plug in the points into the point-slope formula. The formula is
y-y1=m (x-x1). You end up with the answer y-2 =1/8(x+8)
I hope this helps let me know if you have any questions!
