At the city museum, child admission is $5.50 and adult admission is $9.20. On Tuesday, 169 tickets were sold for a total sales of $1195.90. How many child tickets were sold that day

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
