Answer:
No, it isn't linear because the graph is not a straight line.
Step-by-step explanation:
(see picture of graph)
Linear means a straight line, and these points do not form a line, so it is not linear. You can also calculate this by finding the slope between each point and the previous.
Answer:
B, C and F
Step-by-step explanation:
<u>A constant is where a variable or number is on its own</u>
B - 2x-4 (4 is the constant)
C - 8x+y (y is the constant)
F - 7+4x (7 is the constant)
X int can be found by subbing in 0 for y and solving for x
9x - 7y = 21
9x - 7(0) = 21
9x = 21
x = 21/9 which reduces to 7/3...so the x int is 7/3 or (7/3,0) <==
to find the y int, sub in 0 for x and solve for y
9x - 7y = 21
9(0) - 7y = 21
-7y = 21
y = -21/7
y = -3....so the y int is -3 or (0,-3) <==
Area of a circle is π·r²
The center of the circle is at the origin (0,0) and there is a point at (3,0)
This means that the radius (r) of the circle is 3.
Therefore the area of the circle is 9π or 28.27
