Answer:

radius = \sqrt{73}

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x - 1)² + (y + 3)² = 73 ← is in standard form

with r² = 73 ( take the square root of both sides )

r = \sqrt{73}

0.50x-6=4 this is algebra 1 can you please help me
horsena [70]

0.50x-6=4

move -6 to the other side

sign changes from -6 to 6

0.50x-6+6= 4+6

0.50x= 10

divide by 0.50 for both sides

0.50/0.50x= 10/0.50

x= 20

Answer: x= 20

Answer:

(x-1)^2+(y+4)^2=9

Step-by-step explanation:

The equation of a circle is given by:

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

Where (h, k) is the center and r is the radius.

The center of the circle is (1, -4).

And the radius is 3.

Substitute:

(x-(1))^2+(y-(-4))^2=(3)^2

Simplify. Thus, our equation is:

(x-1)^2+(y+4)^2=9

A line contains the points (-5, 3) and (0, -7). What is the equation of this line in slope-intercept form?
pychu [463]

Answer:

D. y = –2x – 7

Step-by-step explanation:

First, find the <em>rate</em><em> </em><em>of change</em><em> </em>[<em>slope</em>]:

-y₁ + y₂\-x₁ + x₂ = m

- \frac{3 - 7}{5 + 0} = -\frac{10}{5} = -2

In this case, the y-intercept of [0, -7] is ALREADY given to you, so we would not have to go further in this case.

I am joyous to assist you anytime.
