Boa drove from the Dead Sea up to Jerusalem and her altitude increased at a constant rate of 740 meters per hour. When she arriv

Alborosie

Answer:

$y=740x-400$

Step-by-step explanation:

The story tells us that Boa drove from the Dead Sea up to Jerusalem. With the data provided, we can assume a linear relationship between altitude and the number of hours. We are given two key data: one point and the rate of change (or slope).

We can easily find the equation of a line with slope m passing through a point (a,b) by using the formula

$y-b=m(x-a)$

In this case, y is the altitude above sea level, and x is the number of hours of driving

The value of m is 740 meters/hour and the known point is x=1.5 hours, y=710 meters. Using these values

$y-710=740(x-1.5)$

$y-710=740x-1110$

$y=740x-400$

Factor completely x³ + 6x² - 3x – 18
$- 6 + 6( - 6)^{2} - 3( - 6) - 18 \\ - 6 +6 \times 6 ^{2} + 18 - 18 \\ - 6 + 6 ^{3} + 18 - 18 \\ - 6 + 216 \\ 210$
with a root of x = -6

the answer is 210
