Answer:
y = 2.1x +5, 21 miles
Step-by-step explanation:
We will denote miles as "x"
Since she tipped the driver $5, that is a flat rate and that will be our y-intercept. Since it costs $2.10 per mile, we need to multiply that number by the number of miles
So our equation will be y = 2.1x +5
In order to figure out how many miles Ann lives from the airport, we need to substitute y for her grand total that she was charged
This gives us 49.10 = 2.10x + 5
First we need to subtract 5 from each side to get 44.10 = 2.10x
We then need to divide both sides by 2.10 to get 21 = x
Ann drove 21 miles
Answer:
5-2√10
Step-by-step explanation:
5-2√10
break them down
√25=5
so 5-√40
then simplify
5-2√10
Answer: 333.33m²
Step-by-step explanation:
Since we are informed that 15 litres of paint covers an area of 250 m2, the the area that 1 liter of paint will cover will be:
= 250m²/15
= 16.666667m²
Therefore, the area that 20 litres of paint will cover will be:
= 16.666667m² × 20
= 333.33m²
Answer:
lines are not perpendicular or parallel
The formula for exponential form is:
e^x = y
Where, y in this case is 1800, e is exponential, and we
are to find e^x.
e^x = 1800
To find for x, we have to multiply both sides with the
natural log, ln.
ln (e^x) = ln (1800)
x ln e = ln (1800)
<span>ln e = 1 and by using
the calculator,</span>
x = 7.496 = 7.5
<span>Therefore the exponential form of 1800 is e^7.5</span>
<span>ANSWER: </span>
