Estimate the solution.

y=x+4
y=3x−1

9514 1404 393

  (x, y) = (2.5, 6.5)

Step-by-step explanation:

I find it easier just to solve the system of equations:

  x + 4 = 3x - 1

  5 = 2x

  x = 5/2 = 2.5

  y = x+4 = 6.5

  (x, y) = (2.5, 6.5)

Additional comments

The first equation has a positive y-intercept and a positive slope, so makes a triangle with the axes in the 2nd quadrant.

The second equation has a negative y-intercept and a (more) positive slope, so makes a triangle with the axes in the 4th quadrant. The slope is greater for this line, so the lines will intersect in the 1st quadrant. Without more effort, the best estimate at this point is that x and y are both positive and y > 4.

ik how do do this just give me a few minutes and i will give it to

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
