Answer:
Step-by-step explanation:
You are given values for x. Plug them in to the given equations. Graph the two lines. Find the intersection. You can tell from the chart when you get the same y value for both equations
Answer:
A = 49 pi
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi (7)^2
A = 49 pi
The area of the composite figure can be solved by separating the figure into 3 portions, which are 2 identical rectangles with one rectangle.
The image of the composite figure will be shown below
Let us sketch out the image of the two identical rectangles
The formula for the area(A) of a rectangle is,
where,
Therefore, the area(A1) of the two identical rectangles are
Let me sketch the second rectangle
Therefore, the area(A2) will be
Hence, the area(A) of the composite figure is
Therefore, the area is
Ax+by=c
y=x+3
subtract x from both sides
Y-x=x-x+3
Y-x=3
-1•(y-x)=-1•3
-y+x=-3
Reorder:
X-y=-3
I’m not sure if it’s 100% correct but that’s all I can do
