Step-by-step explanation:
y = 4x-1
2x+y = 5
2x+(4x-1) = 5
6x - 1 = 5
6x = 6
x = 1
Answer:
A solution of a linear system is an assignment of values to the variables x1, x2, ..., xn such that each of the equations is satisfied. The set of all possible solutions is called the solution set.

Answer:
yeah that's correct
Step-by-step explanation:
now let's recall that a full circle has 360°, so then 1140 = 360 + 360 + 360 + 60.
namely, 1140 is 3 full-go-around the circle and then it lands on the I Quadrant at 60°. Thus cos(1140°) = cos(60°).
what's that cosine of 60°? Check the picture below.
7 qt = 105 gallons per hour
