A fan blade spins at a constant rate. This spinning is known as revolutions. The equation y=750x represents the number of revo

Aneli [31]

Answer:

(0,0)

(1, 750)

(2, 1500)

(3, 2250)

Step-by-step explanation:

To list the ordered pairs (x,y) we need to calculated the number of revolutions for minutes 0, 1, 2 and 3.

To calculated the number of revolutions for 0 minutes, we need to replace x by 0 in the initial equation and solve for y as:

y = 750*x

y = 750*0

y = 0

It means that our first ordered pair is (0,0), because when we replace x by 0 we get y equal to 0

At the same way, if we replace x by 1, we get:

y = 750*x

y = 750*(1)

y = 750

So, our second ordered pair is (1, 750)

Then, replacing x by 2, we get:

y = 750*x

y = 750*(2)

y = 1500

So, our third ordered pair is (2, 1500)

Finally, replacing x by 3, we get:

y = 750*x

y = 750*(3)

y = 2250

So, our last ordered pair is (3, 2250)

Which system of equations can be used to find the roots of the equation 12 x 3-5x=2 x 2+x+6

kirill [66]

Answer:

Option (a) is correct.

The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Step-by-step explanation:

Given : Equation $12x^3-5x=2x^2+x+6$

We have to construct a system of equations that can be used to find the roots of the equation $12x^3-5x=2x^2+x+6$

Consider the given equation $12x^3-5x=2x^2+x+6$

To construct a system of equation put both sides of the given equation equal to a same variable.

Let the variable be "y", Then the equation $12x^3-5x=2x^2+x+6$

becomes,

$12x^3-5x=y=2x^2+x+6$

Thus, The system of equation becomes

$y=12x^3-5x\\\\ y=2x^2+x+6$

Option (a) is correct.

Ben got 56 out of 79 in a math test what was his score give it to 1 decimal place i need to no asap

Leviafan [203]

Step-by-step answer:

56 out of 79 is a percentage less than a hundred, because 56 is less than 79.

Take out the calculator then divide fifty-six by seventy-nine, then multiply by a hundred to get seventy-one percent.

If calculators are not allowed, notice that seventy-nine is close to eighty. So divide fifty-six by eighty to get 70%. But since we divided by eighty instead of seventy nine, we need to add approximately one percent to get the right answer.
