Something divide by something 65?
The question "Something divided by something equals 65" can be represented as a mathematical equation: x / y = 65. To solve for x or y, we need more information or context. If x is known, we can find y by dividing x by 65. If y is known, we can find x by multiplying y by 65. Without specific values for x or y, the equation remains unsolvable.
How do you answer Ray bought 15 pencils for 7.75 Some cost 45 each the rest 65 each How many of each did Ray buy. Answer step by step please?
x= # of pencils that cost .45 y= # of pencils that cost .65 So now you need 2 equations for 2 variables: 15= x+y This equation is saying: 15 total pencils bought= pencils that cost .45 + pencils that cost .65 The second equation is: 7.75= .45x + .65y This equation is saying: total money spent (7.75)= price of pencils (.45) times # of pencils + price of pencils (.65) times # of pencils Then you combine these two equations, but first switch around the first equation to look like: y=15-x Then you replace the "y" in the second equation by putting in what y equals the first equation: 7.75= .45x + .65(15-x) Then distribute and solve for x: x = 10 Then enter 10 into the first equation for x to figure out y: y= 15- 10 y= 5 So your answer is-- Ray bought 10 pencils that cost .45 and 5 pencils that cost .65

What is the y-intercept for y equals 45x plus 65?
Given the equation y = 45x + 65, the y-intercept is 65. We know this because the equation is already in the form y = mx + b, where m is the slope, and b is the y-intercept.

What is the tangent equation line of the circle x2 plus 10x plus y2 -2y -39 equals 0 at the point of contact 3 2 on the Cartesian plane?
Equation of circle: x^2 +10x +y^2 -2y -39 = 0 Completing the squares: (x+5)^2 +(y-1)^2 = 65 Center of circle: (-5, 1) Slope of radius: 1/8 Slope of tangent line: -8 Point of contact: (3, 2) Equation of tangent line: y-2 = -8(x-3) => y = -8x+26 Note that the tangent line meets the radius of the circle at right angles.

What is the equation of the tangent line that touches the circle x squared plus 10x plus y squared -2y -39 equals 0 at the point of 3 2 on the Cartesian plane showing work?
First find the slope of the circle's radius as follows:- Equation of circle: x^2 +10x +y^2 -2y -39 = 0 Completing the squares: (x+5)^2 + (y-1)^2 -25 -1 -39 = 0 So: (x+5)^2 +(y-1)^2 = 65 Centre of circle: (-5, 1) and point of contact (3, 2) Slope of radius: (1-2)/(-5-3) = 1/8 which is perpendicular to the tangent line Slope of tangent line: -8 Tangent equation: y-2 = -8(x-3) => y = -8x+26 Tangent equation in its general form: 8x+y-26 = 0

What is the tangent equation that touches the circle x squared plus 10x plus y squared -2y -39 equals 0 at the point of 3 2 on the Cartesian plane?
A line with slope m and a point (x0, y0) on it has equation: y - y0 = m(x - x0) The slope of the tangent is perpendicular to the slope of the radius to the point (3, 2) The product of the slope of a line and a line perpendicular to it is -1. A circle with centre (X, Y) and radius r has equation: (x - X)² + (y - Y)² = r² For x² + 10x + y² - 2y - 39 = 0 and the point (3, 2): x² + 10x + y² - 2y - 39 = 0 → x² + 10x + (10/2)² - (10/2)² + y² - 2y + (2/2)² - (2/2)² - 39 = 0 → (x + 5)² - 25 + (y - 1)² - 1 - 39 = 0 → (x - -5)² + (y - 1)² = 65 → the circle has centre (-5, 1) and radius √65. The slope m' of the radius to (3, 2) from the centre of (-5, 1) is given by: slope = change_in_y / change_in_x → m' = (2 - 1) / (3 - -5) = 1/8 → slope m of the tangent is: mm' = -1 → m = -1/m → m = -1/(1/8) = -8 Thus the tangent has equation: y - 2 = -8(x - 3) → y - 2 = -8x + 24 → y + 8x = 26
