Answer:

(x)^2 + (y)^2 = 4^2

Step-by-step explanation:

The standard form of an equation  for a circle is

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

Since the center is 0,0  and the radius is 4

(x)^2 + (y)^2 = 4^2

Answer:

x^2+y^2=16

Step-by-step explanation:

x^2+y^2=r^2 is the mother function of the equation of a circle centered at r with radius r

since r is defined to be 4 and 4^2 is 16 therefore, the equation would then be

x^2+y^2=16

Answer:

(4,2)

Step-by-step explanation:

Just by looking at the graph, you can see that they intersect at (4,2). But just to check:

x - 2 = -0.5x + 4

1.5x = 6

x = 4

y = 4 - 2 = 2

(4,2)

Is -5/11 equivalent to -5/-11 ? Why or why not?
faltersainse [42]
No, -(5/11) is equivalent to -5 all over 11 so -5/11. You cannot change the denominator

Hello can anyone give me the step by step answer?
NISA [10]

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, - 42 ) and (x₂, y₂ ) = (- 3, - 17 ) ← 2 ordered pairs from the table

m = \frac{-17-(-42)}{-3-(-8)} = \frac{-17+42}{-3+8} = \frac{25}{5} = 5

The line crosses the y- intercept at (0, - 2 ) , then

y = 5x - 2 → C
