Answer:

A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>

Step-by-step explanation:

Let convert this into slope intercept form

10y - 200x = 500

10y = 200x + 500

y = 20x + 50

So now let answer these questions,

A is TRUE the slope is the number in front of the x value. It is 20 so a is true.

B is False, Using (0, 500) The equation is wrong

500 = 20(0) + 50 ??

C is false, we have a positive slope so it shifts upward from left to right.

D is false

the slope isn't 200.

E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get

y = 20(0) + 50

It equal 50.

1) Expand and simplify the following:<br>a)3(x squared plus 3x cubed - 2)​
Musya8 [376]

Answer:

3x³ + x² - 2

Step-by-step explanation:

a) 3(x squared plus 3x cubed - 2)​

x squared = x²

3x cubed = 3x³

3(x squared plus 3x cubed - 2)​

= 3(x² + 3x³ - 2)

= 3x² + 9x³ - 6

Rearrange according to power

= 9x³ + 3x² - 6

When the expression is divided by 3, it is equivalent to

3x³ + x² - 2

Lemur [1.5K]
The answer is 52

x - the number of students in a bus

4 + 9x = 472
9x = 472 - 4
9x = 468
x = 468 / 9
x = 52
