Answer:
50 i believe
Step-by-step explanation:
Y = 1/3x ? 6....slope here is 1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3 (see how I flipped 1/3 and changed the sign)
y = mx + b
slope(m) = -3
(-9,12)...x = -9 and y = 12
now we sub and find b, the y int
12 = -3(-9) + b
12 = 27 + b
12 - 27 = b
-15 = b
so ur perpendicular equation is : y = -3x - 15
-1+3m=2m+4
put the like terms together
3m-2m=4+1
m=5
Check the picture below
surely you know how much that is.
Answer:
-18x+73
Step-by-step explanation:
-9 times 2x is -18x
-9 times -7 is 63
63+10=73
so, -18x+73 is your answer
