30 because the angles of the triangle should be 180. Since we know one is 90 the other is 60 so 180-(90+60)=30

What is the solution to the system of equations below? Y=-4/5x-6 & y=-30
Ainat [17]
So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:

-30=-4/5x-6

And then solve for x:

Add 6 on both sides. 

-24=-4/5x

Then multiply by the reciprocal of -4/5.

-5/4*-24=-5/4*-4/5x

x=30 

But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.

Rectangle ABCD is reflected over the y-axis. What rule shows the input and output of the reflection, and what is the new coordin
Vitek1552 [10]

Solution:

As given Rectangle ABCD is reflected over the y- axis.

When a shape or geometrical figure is reflected through a line it's distance that is distance of image from line and distance of Pre-image from that line is always same.Also perpendicular distance of vertices of any polygon that is considered for reflection has same distance from that line after reflection and before reflection.

Suppose the coordinate of A be (x,y) and considering Rectangle A B CD lie in first quadrant then when it is reflected through y - axis that is through the line x=0, it's new coordinate will become A' (-x,y).

If rectangle is in second quadrant having Vertices that is vertices of A (-x,y) then reflected over line that is x=0,→ y axis then Vertices of A' (x,y).

If rectangle is in third quadrant having Vertices that is vertices of A (-x,-y) then reflected over line that is x=0,→ y axis then Vertices of A' (x,-y).

If rectangle is in fourth quadrant having Vertices that is vertices of A (x,-y) then reflected over line that is x=0,→y axis then Vertices of A' (-x,-y).

a total of 582 tickets were sold for the school play. they were with adult tickets or student tickets. there were 68 fewer stude
topjm [15]

Answer:

257 adult tickets

Step-by-step explanation:

Let x be the total sold adult ticket.

Given:

Total 582 tickets were sold.

There were 68 fewer student tickets sold than adult tickets

Then there were x-68 students.

So, The total sold ticket equation is

x+(x-68)=582

2x-68=582

2x=582-68

x=\frac{514}{2}

x=257

Therefore, 257 adult tickets were sold
