Word problem: 1. In a test (+5) marks are given for every correct answer and (-2) marks are given (4)
for every incorrect answer.
a) Jay gets eight correct and seven incorrect answers. What is his score?
b) Tom answered all the questions and scored 20 marks though he got 10 correct answers.
How many incorrect answers has he attempted?

10

Step-by-step explanation:

Marks given for one correct answer = 5

So, marks given for 10 correct answers

= 5 X 10 = 50

Radhika's score = 30

Marks obtained for incorrect answer

= 30- 50 = -20

Marks given for one incorrect answer

= (-2)

Therefore, number of incorrect answers

= (−20)÷(−2)=10

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
