Answer:

x=-2, y=-10

Step-by-step explanation:

Since both equations are equal to y, we can set them equal to each other and solve

x-8=5x

Subtract x from both sides

-8=4x

Divide both sides by 4

x=-2

Next, we need to find a y

Substitute -2 in for x in one of the equations and solve

y=5x

y=5*-2

y=-10

x=-2, y=-10

f(n) = n² + 20

f(1) = 1² + 20 = 21

f(2) = 2² + 20 = 24

f(3) = 3² + 20 = 29

f(4) = 4² + 20 = 36

f(5) = 5² + 20 = 45

f(6) = 6² + 20 = 56

a) first three terms

Answer: 21, 24, 29

b) how many < 50

f(5)=45, f(6)=56 so

Answer: 5

Answer:

v = 80 mph

Step-by-step explanation:

Given that,

The distance from Wakefield to London is 180 miles.

The train travels this distance in 2 hours 15 minutes.

We need to find the average speed of the train. The average speed of the train is equal to the total distance covered divided by the time taken.

$v=\dfrac{d}{t}\\\\v=\dfrac{180\ miles}{(2+\dfrac{15}{60})\ h}\\\\v=80\ mph$
