Which of the following equations represents a linear function?
liubo4ka [24]

A linear equation has maximum power of a variable(variables) 1.

In order to find the linear equations we need to check the equations with variable with power one.

Also the variable should be in numerator only.

Let us check option one by one:

a-y=√x + 1 we have a radical on x.

Therefore, it's not a linear equation.

b-y=1/x

We have x in the denominator of 1.

Therefore, it's not a linear equation.

c-y=x^2 +4

We have power 2 of x. Therefore, it's not a linear equation.

d-y = -2/3x + 4/3.

We have x and y powers only 1.

Therefore, it's the only linear equation.

<h3>Therefore, correct option is D option. d-y = -2/3x + 4/3</h3>

the amusement park also has water rides 30% of the 80 rides are water-related how many water-related rides does the park have
sergejj [24]

Answer:

24.

Step-by-step explanation:

So you need to fine 30% of 80.

I did the following method:

-Break it down, and do, 80 -/- 10 which is 8, now you have 10%, and you need to find 30, times your 10% by 3, so 24.

-Therefore, 24 out of 80 rides at the amusement park are water-related.


Hope this helps!

The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. A wind speed of 37 miles per ho
vfiekz [6]

Answer:the output for a wind speed of 40 miles per hour is 810.8 kilowatts.

Step-by-step explanation:

The power P produced by a wind turbine is directly proportional to the cube of the wind speed S. This means that

P is directly proportional to S

Introducing a constant of proportionality, k, it becomes

P = kS

A wind speed of 37 miles per hour produces a power output of 750 kilowatts. This means that

750 = k × 37

k = 750/37 = 20.27

The expression becomes

P = 20.27S

Therefore, the output for a wind speed of 40 miles per hour would be

P = 20.27 × 40

P = 810.8
