Question 3(Multiple Choice Worth 4 points)
boyakko [2]

Answer:

The correct option is (1).

Step-by-step explanation:

The given system of equation is,

y=-x+4       ..... (1)

y=3x+3      .... (2)

The solution of the system of equation is the point where both line intersect each other.

Solve the equation by method of elimination.

Multiply equation 1 by 3.

3y=-3x+12    ... (3)

Add equation (2) and (3).

y+3y=3x+3+(-3x+12)

4y=3x+3-3x+12

4y=15

y=3.75

Put this value in equation 1.

3.75=-x+4

x=-3.75+4

x=0.25

Therefore, the lines intersect each other at (0.25,3.75). So, the first option is correct.

The table shows the results of a survey. Of those surveyed, 275 students said they prefer pop music
KiRa [710]

Answer:

440 students.

Step-by-step explanation:

Given is a table showing the results of a survey.

No of people surveyed = n (say)

No of people who prefer pop music = (5/8) n

(Since given in the table proportion for pop music = 5/8)

But actual studdents who prefer pop music =275

In other words

5n/8 = 275

Cross multiply to solve

5n=2200

divide by 5

n= 440

Thus total people surveyed= 440

Verify:

No of students who prefer Pop music = 440(5/8) = 55(5) = 275

Thus verified
