What will the graph look like for a system of equations that has no solution?(1 point) Responses You will see the lines intersect at two different points. You will see the lines intersect at two different points. You will see perpendicular lines. You will see perpendicular lines. You will see lines on top of each other so that they form the same exact line. You will see lines on top of each other so that they form the same exact line. You will see parallel lines. You will see parallel lines. You will see the lines intersect at only one point.
The correct answer is: You will see parallel lines.
Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold. (7 points) Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.
The equation that represents this situation to find the cost of all adult and student tickets sold is:
4a + 2.50s = 2820
4a + 2.50s = 2820
900 tickets are sold for the spring fling. Write an equation to represent this situation. a + Response area =
a + s = 900
Use the above system of equations to determine how many adult and student tickets were sold. Response area adult tickets and Response area student tickets were sold.
To determine how many adult and student tickets were sold, we can solve the system of equations:
4a + 2.50s = 2820
a + s = 900
There are multiple methods to solve this system of equations. One method is substitution.
We can solve the second equation for a in terms of s:
a = 900 - s
Substitute this value of a into the first equation:
4(900 - s) + 2.50s = 2820
Simplify:
3600 - 4s + 2.50s = 2820
-1.50s = -780
s = 520
Substitute this value of s into the second equation to find a:
a + 520 = 900
a = 900 - 520
a = 380
Therefore, 380 adult tickets and 520 student tickets were sold.
4a + 2.50s = 2820
a + s = 900
There are multiple methods to solve this system of equations. One method is substitution.
We can solve the second equation for a in terms of s:
a = 900 - s
Substitute this value of a into the first equation:
4(900 - s) + 2.50s = 2820
Simplify:
3600 - 4s + 2.50s = 2820
-1.50s = -780
s = 520
Substitute this value of s into the second equation to find a:
a + 520 = 900
a = 900 - 520
a = 380
Therefore, 380 adult tickets and 520 student tickets were sold.
