D=a+b+c solve for b<br> I need some help

Hoochie [10]

Hi Walker

d=a+b+c

Flip

a+b+c=d

Add -a to both sides

a+b+c-a=d-a

b+c=-a+d

Now add -c to both sides

b+c-c=-a+d-c

b= -a-c+d

Find the radius of the circle whose equation is 3x² + 3y² = 75.

Flauer [41]

Answer:

Step-by-step explanation:

The equation of a circle:

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

(h, k) - center

r - radius

We have the equation:

$3x^2+3y^2=75$ <em>divide both sides by 3</em>

$x^2+y^2=25\to r^2=25\to r=\sqrt{25}\to r=5$

If f(x) = x^2 + 3x – 2. find f(-2) .<br>f(-2) = -4<br>f(-2) = 4<br>f(-2) = -2<br>f(-2) = 2

Reptile [31]

Answer:

f(-2) = - 4

Step-by-step explanation:

f(x) = x² + 3x - 2

f(-2) = ( -2)² + 3 *(-2) - 2

= 4 - 6 - 2

= 4- 8

= - 4

Hope it will help :)
