The temperature begins to drop, the day light hours shorten, and plants start to go dormant; there is three.
Answer:
x = 1
Step-by-step explanation:
If y = -3...
y = 7x - 10
-3 = 7x - 10
10 + -3 = 7x - 10 +10
7 = 7x
(1/7) 7 = 7x (1/7)
1 = x
Answer:
5.50/40
Step-by-step explanation:
5.50 divided by $44
this 5.50/40 is ths same as this
5.50 divided by $44
So
5.50/40 is your answer
Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.
I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>
