Radius and a center located at (0, - 6) Which equation represents this circle?

Mathematics
1 answer:
MArishka [77]3 years ago
7 0

Answer:

A.

Step-by-step explanation:

The center  is at (0, -6) so the equation is:

(x - 0)^2 + ( y + 6)^2 = r^2

x^2 + (y + 6)^2 = r^2

r^2 = 11

Answer is x^2 + (y + 6)^2 = 11.

Write the standard form of the line that contains a y-intercept of -3 and passes through the point (3, 0). Include your work in
mina [271]
We have two points, (3,0) and (0,-3).  So we can find the slope of the line:

m=(y2-y1)/(x2-x1)

m=(-3-0)/(0-3)

m=-3/-3

m=1  so far for the line y=mx+b we have:

y=x+b, b is the y intercept which we were told is -3 so

y=x-3

The above is called the slope-intercept form of a line, y=mx+b, the standard form of a line is ax+by=c, so we need to get both variables on one side of the equation..

y=x-3  subtract x from both sides

-x+y=-3

While the above may be acceptable to some, technically the coefficient of x should be expressed as a positive value, so we should divide the above "solution" by -1 to get:

x-y=3

3xsquare-9x-30=0<br> What’s the answer
BartSMP [9]

Answer:

x = - 2 or x = 5

Step-by-step explanation:

Given

3x² - 9x - 30 = 0 ← in standard form

Divide all terms by 3

x² - 3x - 10 = 0

To factor the quadratic

Consider the factors of the constant term (- 10) which sum to give the coefficient of the x- term (- 3)

The factors are - 5 and + 2, since

- 5 × 2 = - 10 and - 5 + 2 = - 3, thus

x² - 3x - 10 = 0

(x - 5)(x + 2) = 0

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 2 = 0 ⇒ x = - 2
