Evaluate the expression for the given value of x
-2/3x + 12 for x = -3

14

Step-by-step explanation:

For this equation you want to replace all the x with -3 which will make the equation:

-2/3(-3) + 12 =

6/3 + 12 =

2 + 12 = 14

14

Step-by-step explanation:

Substitute -3 for x in (-2/3x) + 12:

                                  (-2/3)(-3) + 12, or

                                        2       + 12 = 14

Note that we must multiply (-2/3) and (-3) together BEFORE adding 12.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
