In an equation or inequality, you want to get the variable.

1 answer:

7 0

What you want to do is get the variable x on the left side by itself (just like you would if this were an equation). Be sure to perform the same operations on both sides of the inequality until x is all by itself on the left side.

Solve the following equation 10.5=5z. A. z=-0.5 B. z=15.5 C. z= 2.1 D. z= 5

iVinArrow [24]

10.5=5z
re-order
5z = 10.5
divided both sides by 5
5z/5 = 10.5/5
Simplify
z = 2.1

Answer is C. z= 2.1

Write the equation of a circle with center (-2, 0) and area = 64 pi

kozerog [31]

Answer:

The required equation in standard form is $(x+2)^2+y^2=64$

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

$(x-h)^2+(y-k)^2=r^2$

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is $64\pi$

$\pi r^2=64\pi$

$\implies r^2=64$

We substitute these values into the formula to obtain;

$(x--2)^2+(y-0)^2=64$

We simplify to get;

$(x+2)^2+y^2=64$
