Brody is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. What would be Brody's test score (out of 20) if he
got 9 questions wrong? What would be his score if he got x questions wrong?

Brody's test score is 11/20 and 20 - x/20

Step-by-step explanation:

If Brody gets x questions wrong, this could only possible answer is 20 - x.

Using this formula, we could now answer the first question.

20 - x

20 - 9 = 11

We could then conclude that Brody got 11 correct answers out of 20 answers.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
