Answer:
The center is at ( (-1, -2) and the radius is 5.
Step-by-step explanation:
X^2 + 2X + Y^2 + 4Y = 20
Complete the square on the x and y terms.
(x + 1)^2 -1 + (y + 2)^2 - 4 = 20
(x + 1)^2 + ( y + 2)^2 = 25 Comparing this with the standard form:
(x - h)^2 + (y - k)^2 = r^2
- the center is at ( (-1, -2) and thr radius is 5.
6 tps baking powder. For every 3, there is two. 3 multiplied by 2 is 6.
Answer:
x(x+5)^2
Step-by-step explanation:
x^3+ 10x^2+25x
factor out an x
x(x^2+10x+25)
what numbers multiply to 25 and add to 10
x(x+5) (x+5)
x(x+5)^2
Answer:
822 hours
Step-by-step explanation:
Let's say that you work for h hours. Then since each hour, you charge $10.25, then your total earnings after h hours will be:
10.25 + 10.25 + 10.25 + ... + 10.25, where you add 10.25 to itself h times.
Adding a number n to itself x times is the same as multiplying that number n by x: nx. It's the same thing here: we multiply 10.25 by h because we added 10.25 to itself h times:
10.25 * h
Now, we do know that the actual total amount of money you earn is $8425, so we can just set this value equal to our above expression:
10.25 * h = 8425
Divide both sides by 10.25 to solve for h:
h = 8425/10.25 ≈ 821.95 ≈ 822 hours
Hope this helps!
