Which of the following points are on the line given by the equation y = 5x?
ivanzaharov [21]

Answer:

C and E

Step-by-step explanation:

To answer this question, we plug in the X values of the coordinates into the equation to see if they'll give us the corresponding Y value.

(X, Y)

Example:

Y = 5X

6 != 5 * 3

We do this for every coordinate point. If the problem doesn't make sense, it doesn't fall on the line. Let's test every one of these.

B. (0, 1)

1 != 5 * 0

C. (3, 15)

15 = 5 * 3

D. (4, 2)

2 != 5 * 4

E. (-1, -5)

-5 = 5 * -1

F. (-1, 5)

5 != 5 * -1

* For those who don't know, the !=  is how to say "not equal to" in computer science.

7. A scatter plot was created to show the relationship
Ksju [112]

Answer:

1020 students

Step-by-step explanation:

Given the trend line equation :

y = 0.1x + 18,

where y is the total number of staff members and x is the total number of students.

Using the equation, the predicted number of students in a school with 120 staffs ;

y = 120

y = 0.1x + 18

120 = 0.1x + 18

120 - 18 = 0.1x

102 = 0.1x

x = 102 / 0.1

= 1020 students

What is the simplest form of this expression? -x^3(5x+1)+4x^4
Fantom [35]

Answer:

-x^3*(x + 1)

Step-by-step explanation:

Perform the indicated multiplication and then write out all the terms in descending order by powers of x:

-x^3(5x+1)+4x^4  =  -5x^4 - x^3 + 4x^4

                            =  -x^4 - x^3, or = -x^3*(x + 1)
