Answer:

(x+3)^2 + (y-2) ^2 = 225

Step-by-step explanation:

We can write the equation of a circle in the form

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

where (h,k) is the center and r is the radius

(x- -3)^2 + (y-2) ^2 = 15^2

(x+3)^2 + (y-2) ^2 = 225

Hi there

Root=0.5 means x=0.5

Plug in 0.5 for x
(b-5)0.5^2-(b-2)0.5+b=0
(b-5)0.25-(b-2)035+b=0
Simplify
0.75b-2.25=0
b=3

Hope this helps

kompoz [17]

Answer:

x-y=4

Step-by-step explanation:

y=x−4

The standard form of a linear equation is

Ax+By=C.

Rewrite the equation with the sides flipped.

x−4=y

Move all terms containing variables to the left side of the equation.

Tap for more steps...

x−y−4=0 Add 4

to both sides of the equation.

x−y=4

Sadie finished her math test in sixteen minutes less than three times the amount of times it took her friend Laura to finish.if

amid [387]

Answer:

Sadie took 47 minutes to finish her test.

Step-by-step explanation:

Let Laura's time be x minutes.

Then we have:

x + 3x - 16 = 68

4x = 84

x = 21 minutes.

So Sadie took 3(21) - 16 = 63-16

= 47 minutes.
