Connor wants to solve the equation 4x=26. How could he use graphs to solve this equation?
astraxan [27]

Answer:

  • <u>He should graph the functions f(x) = 4x and g(x) = 26 in the same coordinate plane. The x-coordinate of the intersection point of the two graphs is the solution of the equation.</u>

Explanation:

<em>To solve the equation 4x = 26</em> using graphs, he should graph two functions in the same coordinate plane. The intersection of the two graphs is the solution of the equation.

The functions to graph are f(x) = 4x, and g(x) = 26.

The graph of f(x) = 4x is a line that goes through the origin (0,0) and has slope 4.

Some of the points to graph that line are:

<u>x            f(x) = 4x             </u>

0        4(0) = 0 →    (0,0)

2        4(2) = 8 →    (2,8)

4        4(4) = 16 →   (4,16)

6        4(6) = 24 →  (4, 24)

With those points you can do an excellent graph of f(x) = 4x

The graph of g(x) = 26 is horizontal line (parallel to the y-axis) that passes through the point (0, 26), which is the y -intercept.

You have to extend both graphs until they intersect each other. The x-coordinate of the intersection point is the solution of the function.

While exercising, Carly burns 450 calories per hour biking and 620 calories per hour playing racquetball. Sarah burns 560 calori
Katyanochek1 [597]

Answer:

A

Step-by-step explanation:

30 minutes = half an hour

Carly:

450/2 = 225

620/2= 310

225 + 310 = 535

Carly burned 535 calories total

Sarah:

560/2 = 280

510/2 = 225

280 + 225 = 505

Sarah burned 505 calories total

Carly burned more calories than Sarah
