6x + 4y = 24
2x - 4y = -8
We will use the addition method in solving this system of equation.
6x + 4y = 24
+ (2x - 4y = -8)
8x + 0 = 16
8x = 16
x = 16/8
x = 2
Let us substitute x by its value to get the value of y.
6x + 4y = 24
→ 6(2) + 4y = 24
12 + 4y = 24
4y = 24 - 12
4y = 12
y = 12/4
y = 3
2x - 4y = - 8
→ 2(2) - 4y = - 8
4 - 4y = - 8
-4y = - 8 - 4
-4y = -12
y = -12/-4
y = 3
So x = 2 and y = 3. → (2,3)
The true statement among the choices are:
A) The ordered pair that is the solution to the system lies in Quadrant I .
<span>B) The y-coordinate of the solution is 3.
</span><span>D) The x-coordinate of the solution is 2.</span>
Answer:
$75
Step-by-step explanation:
To find out how much George's mom paid for the 6 tickets, first find the unit rate, that is cost per ticket.
The unit rate/constant of proportionality between cost of tickets (y) and number of tickets (x) can be calculated using the coordinates of any points on the graph.
Using (4, 50), this means that 4 tickets cost $50.
Unit rate/constant of proportionality = y/x = 50/4 = 12.5
This means a ticket costs $12.5.
Therefore, 6 tickets would cost:
6 tickets × $12.5 = $75.
George's mom paid $75 for the tickets?
This is a backup question it would be great to state what question 3 was please
Answer:
0.26
Step-by-step explanation:
I am pretty sure the equation for this is 9x12+108 inches then divide 28.08 by 108 and you should get 0.26.
X is the center of the circle
