(2x/-5x)+x^2
(x(2)/(x(-5))+x^2
(-2/5)+x^2, the x values cancel in numerator and denominator and simplify to -2/5
Answer:
B
Step-by-step explanation:
Because the equation can be written in the form (x-p)^2+(y-q)^2. So it represents a <u>circle</u> with the radius r=3 and the center of (5,0).
Answer:
30.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
11 pi = 2 * pi *r
divide each side by 2 pi
11/2 = 2 ( pi) * r/ ( 2pi)
11/2 = r
We can find the area by
A = pi * r^2
= pi ( 11/2) ^2
= pi ( 121/4)
= pi ( 121/4)
= 30.25 pi
If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.
An example of the equation would be
y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept
Answer/Step-by-step explanation:
A. 
Using b = 2
Using b = 4
Using b = 6
Using b = 8
Using b = 10
Using b = 2
B. 
Using x = 3
Using x = 5
Using x = 7
Using x = 9
Using x = 11
Using x = 13
C. 
Using a = 2
Using a = 3
Using a = 4
Using a = 5
Using a = 6
Using a = 7
D. 
Using y = 2
Using y = 3
Using y = 5
Using y = 10
Using y = 8
Using y = 6
