What is the equation in standard form for the circle with center (0, 0) that goes through the point (-5, 12)?
Mumz [18]

Start with the standard equation of a circle with center at (h,k) and radius r:

(x-h)^2 + (y-k)^2 = r^2. Substitute -5 for h and 12 for k:

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

Next, we substitute -5 for x and 12 for y, with the objective of determining the value of r^2:

(-5-0)^2 + (12-0)^2 = r^2. Then 25 + 144 = 169 = r^2, and r = 13.

Thus, the answer choice "x2 + y2 = 169" is the correct one.

Important: Please use " ^ " to denote exponentiation: x^2 + y^2 = 169.

What is the intersection of lines for the two equations y+3x=1 and y-6=2x?
netineya [11]

Answer:

Step-by-step explanation:

Let's reformat both equations so that y is by itself on each side:

y = -3x + 1

y = 2x + 6

Since we y isolated to one side in both equations, we know the right-hand sides must be equal:

-3x + 1 = 2x + 6

Solving for x will give us the x-coordinate of the point of intersection:

-5x = 5

x = -1

Plugging in this x-coordinate to either of the above equations will give us the y-coordinate of the point of intersection:

y = -3(-1) + 1

y = 4

Therefore, the point of intersection is (-1, 4)

Elena harvested 75 kg of apples last autumn. This autumn, her harvest increased by 24%. How many kilograms of apples did she har
sergejj [24]
She harvested 93 kg of apples.

First you need to set it up like this:
X/75=24/100

Then you cross multiply and get:
1800=100x

The you isolate the variable (divide both sides) and get 18

75+18=93
