The bottom left graph, the lines cross at (-1,-1) and the right side of the graph is shaded
3x - 4y = 28
4x + 10y = 20
First we rewrite the system of equations:
Equation 1:
3x - 4y = 28
3x - 28 = 4y
(3/4) x - 7 = y
Equation 2:
4x + 10y = 20
10y = 20 - 4x
y = 2 - (2/5) x
We have then:
y = (3/4) x - 7
y = - (2/5) x + 2
One line has a positive slope and the other line has a negative slope.
Thus, both lines are connected.
Answer:
D) y = 3/4 x - 7; y = -2/5 x + 2; intersecting lines
all ways are simple if you are able to understand
Answer:
<h2>$326.25</h2>
Step-by-step explanation:
The question is incomplete as we were not given to numbers of adults and children, neveherless we can assume some figures and plug it into the expression
say number of adult is 15
and number of chidren is 30
In this problem we are going to the values of adults and children tickets into the expression for the total cost and return the answer, which is the total cost of tickets sold
given the expression
8.75 x+ 6.50y
substituting for x and y we have
8.75(15)+ 6.50(30)=
131.25+195=$326.25
The total cost for 15 adults and 30 children is $326.25
