Answer:
(x, y) = (-12, 10)
Step-by-step explanation:
9x + 11y = 2 -------(1)
3x + 4y = 4 ----- (2)
Multiply equation (1) by 4 and equation (2) by 11, then subtract equation (2) from (1),
4(9x + 11y) - 11(3x + 4y) = 8 - 44
36x + 44y - 33x - 44y = -36
3x = -36
x = -12
From equation (2),
-3(12) + 4y = 4
-36 + 4y = 4
4y = 4 + 36
4y = 40
y = 10
Angle QSP and 110 are congruent because corresponding angles are congruent
Then subtract 180 to angle QSP to get angle QSR because a straight line is 180
180 - 110
= 70
Then add all the given angles to the triangle subtract it to 180 because the sum of angles of a triangle is 180
70 + 40 + x = 180
x = 180 - 110
x = 70

So we want to see which number line shows the sum 1.5 + 2.5. We will see that the correct option is <u>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</u>
So the number line usually starts at 0 and goes to the first number, 1.5 in this case.
Then, it moves accordingly to the second number, 2.5 (so it will move 2.5 units to the right)
So the number line should start at 0 and move to the right until it meets 1.5 + 2.5 = 4.
From the options, the only that is correct is:
<u><em>"An arrow goes from 0 to 1. 5 and from 1. 5 to 4"</em></u>
