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

Solve the equation 7b-27=8(6+4b)
Snowcat [4.5K]

Answer:

b = -3

Step-by-step explanation:

7b-27=8(6+4b)

Distribute

7b -27 = 48 + 32b

Subtract 7b from each side

7b-7b-27=48+32b-7b

-27 = 48+25b

Subtract 48 from each side

-27-48 = 48+25b -47

-75 = 25b

Divide each side by 25

-75/-25 =25b/25

-3 =b
