Y=mx+b the m is your slope. Here the slope would be -3/4. The b is your y-intercept which is -7.
You can use a factor tree, and if you dont know how to use one, look it up on youtube, theres tons
Answer:
x=1
Step-by-step explanation:
-8x+2(4+2)=4
-8x+2×6=4
-8x+12=4
-8x=4-12
-8x= -8
we multiply both sides with (-1) to get a positive number in the x side
-8x= -8 / ×(-1)
8x=8
x=8/8
x=1
Answer:
40 miles per hour
Step-by-step explanation:
Given that:
Distance = 400 miles
Without tailwind :
Time taken = 2.5 hours
Speed = distance / time
Speed = 400 miles / 2. 5
Speed = 160 miles per hour
With tail wind :
Time taken = 2 hours
Net speed = 160 + x
X. = speed of tail wind
Distance = speed * time
400 = (160 + x) * 2
400 = 320 + 2x
400 - 320 = 2x
80 = 2x
x = 40
Speed of tailwind = 40 miles per hour.
