Step-by-step explanation:
you write it like your adding it but from the 10s on you write the first number and add all 0s behind it
Answer:
(3, 5)
Step-by-step explanation:
y = 2x - 1
3x + 2y = 19
In the second equation, substitute 2x - 1 in for y, since y equals 2x - 1 in the first equation. Solve for x.
3x + 2(2x - 1) = 19
3x + 4x - 2 = 19
7x - 2 = 19
7x - 2 + 2 = 19 + 2
7x = 21
7x/7 = 21/7
x = 3
Pick the first equation to solve for y since it says y =. Substitute 3 in for x.
y = 2x - 1
y = 2(3) - 1
y = 6 - 1
y = 5
I believe that the answer is C
BISECTOR OF AN ANGLE
For y to not be a function of x, there needs to be an x-value that is paired with more than one y-value.
In terms of the sets, you need to find a set where the same x-value is used more than once in two (or more) different (x,y) pairs.
This occurs in the third set, where x=6 is used twice.
