Answer:
y=7
Step-by-step explanation:
To calculate the standard equation of a line given two points, you need to calculate the slope and the y intercept.
The slope is the change in y variables over the change in x variables between two points.
(7-7)/(4-0)
that gives you a slope of 0, ie the line is horizontal. That means that the y value is going to be constant while the x value changes, so you can write the equation as y= y value in any point, so y=7.
Step-by-step explanation:
distance formula d=
√(X2 - X1)² + (Y2 - Y1)²
= √(-9-15)² + (8-3)²
=√(-24)² + (5)²
=√576 + 25
=√601

Answer:
3
Step-by-step explanation:
Multiply both sides by x to get rid or the denominator: 
Get rid of the square root by squaring both sides:
= 4x + 15 = 9x
Just solve for x.

Answer:
im pretty sure its 69 cause if u look its halfway between 33 and 33x2 is 66 and 69 is ther closest to that
Step-by-step explanation:
Let a and c be the number of adult and children tickets sold respectively.
a=2c
6.2c+9.8a=593.4, using a from above in this equation gives you:
6.2c+9.8(2c)=593.4 perform indicated multiplication on left side
6.2c+19.6c=593.4 combine like terms on left side
25.8c=593.4 divide both sides by 25.8
c=23
So 23 child tickers were sold that day.
