How can I write a story about the doubles plus 2 fact 5+7=12.??
2x + 2y = 4
what is the solution of the system of equations?
Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
Answer:
{3,-1}

B.
Domain: {3, 5, 9, 2, –4}; Range: {1, –1, 7}
C.
Domain: {1, –1, 7}; Range: {3, 5, 9, 2, –4}
D.
Domain: {1, 7}; Range: {3, 5, 9, 2 }
Answer:
Step-by-step explanation:
Let's call the our odd numbers , , and , in ascending order. It can be said then that (It is the next odd number after ) and (It is the second consecutive number after ).
Additionally, we can say:
Now, how about we substiute in the value for we found in the first paragraph for in the preceeding equation? This gives us:
We have found that the smallest number is 7. Substituting this into the equations we found in the first paragraph, we find:
The numbers are 7, 9, and 11.
Answer:
The three correct numbers are 7, 9, and 11.
