Answer:
Step-by-step explanation:
-x + 2y = 6
y = 1/2x + 3
sub 1/2x + 3 in for y, back into the first equation
-x + 2(1/2x + 3) = 6 ....distribute thru the parenthesis
-x + x + 6 = 6
6 = 6
The solution to this equation is infinite solutions
X + y = 47
x - y = 3
--------------add
2x = 50
x = 50/2
x = 25
x + y = 47
25 + y = 47
y = 47 - 25
y = 22
ur numbers are 22 and 25
1) It's probably best to use a credit card instead of using cash for most things. It's safest.
2) I can exchange dollars for British Pounds here in the US, at the airport (In Manchester) or at a British bank? It doesn't really matter when I exchange it since there will be a fee? Is there one better way than another?
Answer: x=3, x=1
Step-by-step explanation:
To find the zeros, you would set the equation to 0. Then, you would factor.
y=x²-4x+3
0=x²-4x+3
0=(x-3)(x-1)
Now that we have factored our equation, we will find the zeros by setting each factor equal to 0.
x-3=0 x-1=0
x=3 x=1
