A circle is centered at (5, 4) and has radius 6. Write its equation in standard form.

1 answer:

8 0

A circle equation is (x – h)^2 + (y – k)^2 = r^2 where (h,k) is the center and r is the radius. Now all we have to do is plug in the variables.

Since (h,k)=(5,4) and r= 6

The answer would be C.

Your welcome ;)

The gas tank if your car is 40%, there are 8 gallons of gas in the tank, what is the capacity of the gas tank?

matrenka [14]

The car holds 20 gallons of gas.
40%=8
20%=1/2 of 40%
4=1/2 of 8
so 40+40+20=100
8+8+4=20
100%=20 gallons

4 less than half a number is equal to 2 more than the number

xxMikexx [17]

Answer:

$-12$

Step-by-step explanation:

Let that number be $x$ . We can build an equation, and solve for $x$ .

$4$ less than half of $x$ is $x/2-4$ .

$2$ more than $x$ is $x+2$ .

We are given that the two quantities are equal, so we have that $x/2-4=x+2$ .

Adding $4$ to both sides gives $x/2=x+6$ .

Multiplying both sides by $2$ gives $x=2(x+6)=2x+12$ .

Subtracting $2x$ from both sides gives $-x=12$ .

Multiplying both sides by $-1$ gives $x=-12$ .

So, the number is $\boxed{-12}$ and we're done!

The check is left as an exercise to the reader.
