Answer:
y = 9x - 40
Step-by-step explanation:
Using the point-slope equation of a straight line is the fastest approach here, since we already have the slope and a point:
y - k = m(x - h) becomes y - 5 = -9(x + 5)
Solving for y, this becomes y = 9x + 5 - 45, or y = 9x - 40
1) -10x2+20x-1
2) -2(5x2+2x-1)
Answer:
4+7b
Step-by-step explanation:
4+ (b*12)+(b*-3)-2b
4+12b-3b-2b
4+12b-5b
7+7b
Since you didn't answer i think JL is x+26
JK=x+26-x-22=4
KM=19
JM=4+19=23
