I did 54/8 because you are multiplying D×8 and the product of 54/8= 6.75 so yeah the answer is 6.75
Answer:
These equations are in slope-intercept form. I can use the y-intercept and slope to graph both lines. I plot the y-intercept and use rise over run to locate another point on the line. Then, I can draw a line through the two points.
Step-by-step explanation:
Answer:
No, the points are in a linear pattern.
Step-by-step explanation:
Residual plot is a graph that shows the residuals on the vertices. The y-axis has residual values and x-axis has independent variables. The horizontal axis shows the independent variables to determine the best fit for a set. The graph given is in a linear pattern. The random pattern shows that linear model is good fit.
x+y=12
x-y=4
Then you solve:
x+y=12
-y -y
x=12-y
x-y=4
+y +y
x=4+y
4+y=12-y
+y +y
4+2y=12
-4 -4
2y=8
divide both sides by 2 to isolate y
y=4
Plug it into one of the equations
x+4=12
-4 -4
x=8
