Answer:
x = 8, y = 6
Step-by-step explanation:
2x + 5y = 46______(1)
3x - 2y = 12_______(2)
(1) x 3 --> 6x + 15y = 138
(2) x 2 --> 6x -4y = 24
(1) - (2) --> 19y = 114
y = 6 sub into (2)
3x - (2 x 6) = 12
3x = 24
x = 8

Step-by-step explanation:
Four friends all give each other presents. The total cost of the presents is £80.52. We need to find the mean cost of a present in pounds. So, the mean cost of a present is equal to 20.13 .
Answer:
well, we do not have the options here, but we can find the equation of the graph, so the equations that are different from that are the answer to this question:
in the graph, we can see that it goes through the points:
(0,1) and (2,0)
Remember that the slope of a line that goes through the points (x1, y1) and (x2, y2) is:
s = (y2 - y1)/(x2- x1)
then the slope for our line is:
s = (0 - 1)/(2 -0) = -1/2
Then our line is:
y = -(1/2)*x + b.
b is the y-intercept, and we know that when x = 0 y = 1, then:
1 = -(1/2)*0 + b
1 = b
then the equation is:
y = -(1/2)*x + 1
Answer:
Line equation: y=4x−22
