Answer:
y = 10
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, hence
x + 10 = 110 - 4x ( add 4x to both sides )
5x + 10 = 110 ( subtract 10 from both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Using the other pair of congruent sides, then
3y - 10 = 2x - 20 = (2 × 20) - 20 = 40 - 20 = 20, thus
3y - 10 = 20 ( add 10 to both sides )
3y = 30 ( divide both sides by 3 )
y = 10
Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)
___________________
3x+5y=57
5x+5y=75
minus the equations top to bottom=
-2x= -18
x= -18/(-2)
x=9
He bought a total of 9 children tickets

We have been given a graph that involves Real axis and Imaginary axis.
From that graph we have to choose correct line segment which joins complex numbers 2+2i and -1+3i.
We know that if complex number is (a+bi) then real part "a" is always plotted along x-axis and the imaginary part "b" is always plotted along y-axis just like point (a,b) on x-y graph.
So 2+2i means point (2,2) on x-y graph which is at point B.
similarly -1+3i means point (-1,3) which will be at point A.
So the line segment joining them will be AB
Hence final answer is the line segment AB.
