Answer:
x = 1
y = 4
Step-by-step explanation:
5x + 2y = 13
x + 2y = 9
Add both equations.
6x + 4y = 22
Solve for x.
6x = 22 - 4y
x = 22/6 - 4/6y
Put x as 22/6 - 4/6y in the second equation and solve for y.
22/6 - 4/6y + 2y = 9
-4/6y + 2y = 9 - 22/6
4/3y = 16/3
y = 16/3 × 3/4
y = 48/12
y = 4
Put y as 4 in the first equation and solve for x.
5x + 2(4) = 13
5x + 8 = 13
5x = 13 - 8
5x = 5
x = 5/5
x = 1
Total number of possible outcomes = 36
Total number with sum 7 =5
{1, 6} {2, 5} {3, 4}, {5, 2}, {6, 1}
P(sum 7) = 5/36
Answer: 5/36
Answer: 12 only
Step-by-step explanation:
The given graph is representing the function f(x).
To find the value of f(0), we need to check the position of curve at x=0.
It implies we need to check the position of curve on y-axis.
We can see there is only one point where function curve is intersection the y-axis such that at x=0 .i.e. y=12
Hence, from the given graph the value of 
only.
Answer:
b = (a - 6)/V
Step-by-step explanation:
a = Vb + 6
Subtract 6 from both sides:
a - 6 = Vb
b = (a - 6)/V
