Answer:

Adult= $24

child= $21

Step-by-step explanation:

first let's create an equation for each one.

Day 1: 7x+8y=168

day 2: 14x+13y=294

By doing so we can either graph and get the points for x,y or we can substitute each (x=0) (y=0) and solve manually.

x-int.= (24,0)

y-int.=(0,21)

Hi there!

I believe your answer is:

"Line y = −2x + 3 intersects line y = x − 5."

»»————-　★　————-««

Here’s why:

When the system of equations are graphed, they would intersect at a point.
This means that there is a solution to the system. The solution is $(\frac{8}{3} ,-\frac{7}{3} )$ .
While the statement that the lines intersect the x-axis is true, the question asks the statement that describes the <em>solution</em>.
The solution is the point of intersection between the two lines.
