Elodia [21]

Answer:

the value in the five years is  £2,621.44

Step-by-step explanation:

The computation of the value in the five years is given below:

= The value of the second car × (1 - losses percentage)^number of years

= £8,000 × (1 - 0.20)^5

= £8,000 × 0.80^5

= £8,000 ×  0.32768

=  £2,621.44

7. The points (3,5) and (2, y) are on a line with a slope of 3. Find y.​
PtichkaEL [24]

Answer:

We get value of y: y = 2

Step-by-step explanation:

The points (3,5) and (2, y) are on a line with a slope of 3. Find y.​

We can find y using formula of finding slope of a line.

The formula is: Slope=\frac{y_2-y_1}{x_2-x_1}

We have x_1=3, y_1=5, x_2=2, y_2=y and Slope = 3

Putting values and finding y

Slope=\frac{y_2-y_1}{x_2-x_1}\\3=\frac{y-5}{2-3}\\3=\frac{y-5}{-1}\\-1(3)=y-5\\-3=y-5\\y=-3+5\\y=2

So, we get value of y: y = 2
