Answer:

First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

47 divided 985 show how to work it out
Furkat [3]
1. how many times 47 fits on 985? 20×47=940
try higher: 47×21=987. So use 20. subtract 985-940=45. how many times does 47 fit on 45? 0 so the answer should be 20 remainder 45

find the value of x and y if the distance of the point (x,y) from (-2,0) and (2,0) are both 14 units.​
Aleks04 [339]

Answer:

(0, 8\sqrt{3})  and  (0, -8\sqrt{3}) are both 14 units from points (-2, 0) and (2, 0).

Step-by-step explanation:

distance formula

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We want the distance, d, from points (-2, 0) and (2, 0) to be 14.

Point (-2, 0):

14 = \sqrt{(x - (-2))^2 + (y - 0)^2}

\sqrt{(x + 2)^2 + y^2} = 14

Point (2, 0):

14 = \sqrt{(x - 2)^2 + (y - 0)^2}

\sqrt{(x - 2)^2 + y^2} = 14

We have a system of equations:

\sqrt{(x + 2)^2 + y^2} = 14

\sqrt{(x - 2)^2 + y^2} = 14

Since the right sides of both equations are equal, we set the left sides equal.

\sqrt{(x + 2)^2 + y^2} = \sqrt{(x - 2)^2 + y^2}

Square both sides:

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

Square the binomials and combine like terms.

x^2 + 4x + 4 + y^2 = x^2 - 4x + 4 + y^2

4x = -4x

8x = 0

x = 0

Now we substitute x = 0 in the first equation of the system of equations:

\sqrt{(x + 2)^2 + y^2} = 14

\sqrt{(0 + 2)^2 + y^2} = 14

\sqrt{4 + y^2} = 14

Square both sides.

y^2 + 4 = 196

y^2 = 192

y = \pm \sqrt{192}

y = \pm \sqrt{64 \times 3}

y = \pm 8\sqrt{3}

The points are:

(0, 8\sqrt{3})  and  (0, -8\sqrt{3})
