Find the distance between the points (-7,-6) and (5,-6) .
PilotLPTM [1.2K]

<u>Answer:</u>

12 units

<u>Step-by-step explanation:</u>

We are given these two points, (-7,-6) and (5,-6), and we are to find the distance between them.

We know the formula for finding the distance between two points:

<em>Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}</em>

So putting in the values of the given coordinates in the above formula to get:

Distance = \sqrt{(5-(-7))^2+(-6-(-6))^2} = \sqrt{144 + 0}  =12

Therefore, the distance between the two given points is 12 units.

Explain why each table determine if y is proportional to x .
lesya692 [45]

Answer:

see explanation

Step-by-step explanation:

If y is proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k divide both sides by x

k = \frac{y}{x}

This value must be constant for all ordered pairs, thus

k = \frac{4}{6} = \frac{2}{3}

k = \frac{6}{9} = \frac{2}{3}

k = \frac{8}{12} = \frac{2}{3}

k = \frac{2}{3}

Since k is constant for all ordered pairs then y is proportional to x

Solve the following problem and show the work. (x - 6)^2 + (y + 1)^2 = 40
Taya2010 [7]

Answer:

see explanation

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 - 6)² + (y + 1)² = 40 ← is the equation of a circle in standard form

centre = (6, - 1) and r = \sqrt{40} = 2\sqrt{10}
