Which graph represents this system? y = 2 x + 1. y = negative 4 x + 7.

The graph in the attached figure

Step-by-step explanation:

we have

----> equation A

The equation represent a linear equation (line) in slope intercept form

The slope is positive and is equal to

The y-intercept is the point (0,1)

The x-intercept is the point (-1/2,0)

----> equation B

The equation represent a linear equation (line) in slope intercept form

The slope is negative and is equal to

The y-intercept is the point (0,7)

The x-intercept is the point (7/4,0)

Remember that the solution of the system of equations is the intersection point both lines

To find out the intersection point, plot the intercepts, connect them to graph the line and identify the solution

using a graphing tool

The solution is the point (1,3)

The graph in the attached figure

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
