<u>Answer</u>


Option C ,D and E



<u>Explanation</u>



Any time we divide an inequality by a negative number, we reverse the sign



The first error is that,


She did not change the sign > to <



Another mistake is that, she divided one side by -5 and multiplied the second by -5



Also whenever an inequality involve < or > we use an open circle on the number line.



So another mistake is that,



She used a closed circle instead of an open circle on the number line




The correct thing should have been



-5x-3.5\:>\:6.5




-5x\:>\:10





x\:




The number line is shown in the attachment.

PLEASEEE HELP ASAP ITS IMPORTANT !!!!
Orlov [11]

Answer:

The rate of change in the table is 78 students per year

Step-by-step explanation:

Here, we want to get the rate of change of the function

Mathematically, we can get this by using the formula;

m = (y2-y1)/(x2-x1)

(x1,y1) and (x2,y2) are points we are to select from the table

Let us select the point (4,704) and (17,1718) from the table

The slope is thus;

m = (1718-704)/(17-4) = 78 students per year

Elina [12.6K]

Answer: The points of the images are  (9,10), (15,6), (6,4)  and the image is not a rigid motion because the shape changes in side.

Step-by-step explanation:

Since it gives you the scale factor then find they coordinates by multiplying the coordinates by the scare factor.

A(3,5) → (3*3,5*2) → (9,10)

B( 5,3) → (5*3, 3*2) → (15,6)

C ( 2,3)→ (2*3, 2*2)→ ( 6,4)
