D = E + 6
D + E = 20
Plug in the first one in the second one.
E + 6 + E = 20
2E + 6 = 20
2E = 14
E = 7
D = 13

The linear equation of the initial (red ) incline would be y = __x +__
RideAnS [48]

Answer:

y=\underline {1.5}x+\underline 0

Step-by-step explanation:

From the graph,

The initial red incline is a straight line passing through the origin.

So, a straight line passing through the origin is of the form:

y=mx+0

Where, 'm' is the slope.

Now, the slope of a given as the change in y value to change in x value.

Consider the two end points of the red line (0, 0) and (4, 6).

The slope with two points (x_1,y_1)\ and\ (x_2,y_2) on the line is given as:

m=\frac{(y_2-y_1)}{(x_2-x_1)}

Plug in x_1=0,y_1=0,x_2=4,y_2=6. Therefore, slope is:

m=\frac{6-0}{4-0}\\m=\frac{6}{4}=1.5

Hence, the equation of the initial red incline is:

y=\underline {1.5}x+\underline 0

Y=-6x + 5<br> x - y = 5
rodikova [14]

Answer:

y = \frac{-25}{7} or -3.571

x = \frac{10}{7} or 1.429

Step-by-step explanation:

x - y = 5

x = 5 + y

Solve for y:

y =  -6x + 5

y =  -6(5 + y) + 5  Substitute x with 5 + y

y = -6(5) - 6y + 5

y = -30 - 6y + 5

y + 6y = -30 + 5

7y = -25

y = \frac{-25}{7} or -3.571

Solve for x:

x = 5 + y

x = 5 + -25/7

x = \frac{10}{7} or 1.429
