I would say my friend is correct. I think this because when doing function tables, i would often say x2, x5, etc. This would mean that it would be X x 2, and X x 5. If you replace the "x" and turn it into 8, than I would think it would mean the same thing. So, yes. My friend is correct.
I'm not sure if this was what you were looking for, but I hope this helps somehow!
Answer:
6/25
Step-by-step explanation:
What I did to solve this is finding the equation of the line using slope intercept form y is the cost of the ride which increases as you increase mileage or move along the X axis. My points are (2, 5.25) and (5,10.5)
<span>y=mx+b </span>
<span>m=y2-y1/x2-x1 </span>
<span>m=(10.5-5.25)/(5-2) </span>
<span>m=5.25/3=1.75 or 7/4 </span>
<span>y=7/4x+b enter one point for the values of x and y to find b </span>
<span>10.5=(1.75X5) + b </span>
<span>10.5=8.75 + b </span>
<span>b=1.75 </span>
<span>The equation of the line is y=7/4x+1.75 (I also double checked using the second point) </span>
<span>Then all you have to do is enter the mileage 3.8 for the value of X and solve for y </span>
<span>y=(7/4 X 3.8) + 1.75 </span>
<span>y=6.65+1.75 </span>
<span>y=8.4 The cab ride for the 3.8mile trip is $8.4
I hope this helps</span>
Answer:
- 1/2
Step-by-step explanation:
(-4/5) × (- 5/8)
- 4/5 × - 5/8
First we mulitply across
The top and the bottom.
- 20 / 40
because -4 × -5 = +20
and -5 × -8 = +40
Now we simplify the fraction
- 20 / 40
= - 2 /4
= - 1/2
Because we have to simplify it and so I divided it by 10 first.
-20 ÷ 10 = -2 and -40 ÷ 10 = -4
Then I simplified it again by dividing it by 2.
-2 ÷ 2 = -1 and -4 ÷ 2 = -2
So finally we have:
-1/2
And we cannot simplify that anymore so that is the answer.
Hope that helped!
