3x-2x^2+7-3x^2
=3x-2x^2-3x^2+7
=3x-5x^2+7
=-5x^2+3x+7 that’s how it’s solved and that’s the answer as well. Come back for help
Answer:
y = 5x-7
Step-by-step explanation:
y-y/x-x = slope
-12-3/-1-2 = -15/-3 = 5
next plug in slope and coordinates
y=mx+b
3=5(2)+b
solve for b
3=10+b
-7=b
Answer:
you cannot answer this because there is not enough information to determine what to solve
Step-by-step explanation:
Answer:
16m/s
Step-by-step explanation:
distance travelled from L to M = 6 x 10 = 60m
distance travelled from M to N = 160 - 60 = 100m
time taken to travel from M to N = 100/25 = 4 seconds
average speed = total distance / total time = 160m / (6 + 4) seconds = 16m/s
hope that helps!
this is a question on speed, distance and time. I have a formula for it up in my insta page (learntionary) if you need it :)
-3/10 + -17/10 = -20/10 = -2
Hope that helped!
