- 2y + 3 = - 4y<br> The solution set is what???

lianna [129]

Answer:

Y=-3/2

Step-by-step explanation:

-2y+3=-4y

Move constant to the right by adding its opposite to both sides

-2y+3-3=-4y-3

Eliminate the opposites

-2y=-4y-3

collect the like terms

-2y+4y

collect the like terms

(-2+4)y

Calculate the sum

2y=-3

divide both sides of the equation by 2

2y÷2=-3÷2

Any expression divided by itself equal 1

y=-3÷2

y=-3/2

What is the equation for the translation of x2 + y2 = 16 seven units to the right and five units up?

asambeis [7]

Answer:

(x − 7)2 + (y − 5)2 = 16

Step-by-step explanation:

The given circle has equation

$\sf \: x^2+y^2=16x$

The equation of a circle with center (h,k) and radius r units is

$\sf(x-h)^2+(y-k)^2=r^2(x−h)$

$\sf(x-7)^2+(y-5)^2=4^2(x−7)$

$\sf(x-7)^2+(y-5)^2=16(x−7)$

<h2>❖ Tip❖ :- </h2>

This is the equation that has its center at the origin with radius 4 units.

When this circle is translated seven units to the right and five units up, then the center of the circle will now be at (7,5).

Vis inversely proportional to r, when r = 3, V= 10.

guapka [62]

Answer:

Constant of proportionality = 30

Example: r = 6, V = 5

Step-by-step explanation:

Inverse proportion: V*r = constant

Given r=3, V=10, constant = V*r = 30

Example:

r = 6, V = 30/6 = 5
