Average speed = total distance travelled / time taken
in this case total distance = 2x miles
time taken for first half of the journey = x/10 hours and for second part its x / 8 hours
average speed = 2x / ( x/10 + x/8) = 2 x / ( 4x + 5x / 40)
= 2x * 40 / 9x = 80 / 9 mph 8.89 mph
Answer:
y=2x-2
y=3x+1
Step-by-step explanation:
To solve this I will be using the point slope formula
It is as follows
y-y₁=m(x-x₁)
We can choose any m value so I will be choosing m=2
(x₁,y₁) will be (-3,-8) respectively because all we want is for the line to pass through that point
so we have
y-(-8)=2(x-(-3)
We can simplify this to
y+8=2(x+3)
y+8=2x+6
y=2x-2
We then repeat this process but choose a new m (the m value doesn't really matter as long as it's not 0)
I will choose 3
so we have
y-(-8)=3(x-(-3))
Which gives u
y+8=3(x+3)
y+8=3x+9
y=3x+1
