Answer:
y= 3 when x= 0
y=3
Step-by-step explanation:
in the problem, there's a patten in the difference of X and Y,
at first, Y is 3 more than X (2 and 5)
then y is 4 more, 5 more, and 6 more.
y goes up by 1 each time
so if Y is 5 when X is 2, then when X is 1 Y is 4
when X is 0 Y is 3
Answer:
The roots are the x-intercepts, where the parabola crosses the x-axis. If the parabola opens up and it's vertex is below the x-axis then it crosses the x-axis in two places and has two (real) roots.
Step-by-step explanation:
<span>Solution can be gained by using "Product of means = Product of extremes" concept. So the information we have is 23 miles on 1 gal and 135 mile on 'x' gal.
23 : 1 :: 135 : x
As per Product of means = Product of extremes,
23 multiplied x = 135 multiplied by 1.
And x will be 135 divided by 23 which is 5.86 gal
Now, we have to convert gal to liters, 1 gal = 3.78 liters,
so 5.86 gal = 5.86 multiplied by 3.78, which is 22.15 liters.
Hence, 22.15 liters of gasoline are needed for a 135 mile trip</span>
