The Unit 6 SBA has ten questions worth 26 points. The SBA consists of True/False questions worth 2 points each and selected response questions worth 3 points each. How many of each type of question are on the Unit 6 SBA?

Number of 2 points question = 4, Number of 3 points question= 6.

Step-by-step explanation:

Let x = Number of 2 points question, y= Number of 3 points question.

As per given,

x+y  = 10    ...(i)

2x+3y = 26  ...(ii)

Multiply 2 on both sides of (i), we get

2x+2y=20     (iii)

Eliminate (iii) from (ii), we get

y=6

Put value of y in (i), x+6=10

⇒ x=4

Hence, Number of 2 points question = 4, Number of 3 points question= 6.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

both equations and proportions are better.
