On a piece of paper graph the system of equations. Then determine which answer choice matches the graph you drew and identify th e solution to the system.
y=2x+1
y+-x+4
2 answers:
Answer:
I think you meant for the plus sign in the second problem to be an = sign so the equation looks like this y=-x+4
If so your answer is A the first graph
I graphed it on desmos calculator
Answer:
Option A
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
The solution of the system of equations is the intersection point both graphs
using a graphing tool
The intersection point is
therefore
The solution of the system of equations is the point

Answer:
$29.50
Step-by-step explanation:
Not sure how your teacher wants you to round up.
$29.4975
Rounded -> $29.50
I'm assuming 2 decimal places; would be $29.50.
Create a a system of 2 equations: 2x + y = 27 and 2y + x = 9, with x being the first number and y being the second. solve for the two variables and you'll get the first number is 15 and the second is -3.
