Answer:
(Unusual)
Step-by-step explanation:
1/5 for one drawing
1/5 chance to win once, if there is only one game.
Then multiply them together to get 1/25.
If you need in decimal form 1/25 = 0.04 (unusual)
Hello from MrBillDoesMath!
Answer:
x = -3, y = 0
Discussion:
5x + 5y = -15 =>
x + y = -3 => (divide both sides by 5)
x + y - y = -3 -y => (subtract y from both sides)
x = -3 - y
Substitute x = -3 - y into the top equation:
-3x - 5y = -9 =>
-3(-3-y) - 5y = 9 => ( substitute -3 -y for x)
(-3)(-3) + (-3)(-y) - 5y = 9 =>
9 + 3y - 5y = 9 => ( -*- is a + number)
9 -2y = 9 =>
9 - 9 -2y = 9 - 9 => (subtract 9 from both sides)
-2y = 0 =>
y = 0
Since x = -3 -y, x = -3 - 0 = =3

Answer:
The correct answer is: Option 3.
Step-by-step explanation:
To begin the problem asks to find 
· 
which can be defined as ](https://tex.z-dn.net/?f=%5Bf%2Ag%5D%28x%29)
. Now we are given that:
So now we need to 'multiply' our two algebraic expressions as follow:
Eqn.(1)
The domain of Eqn. (1) is all real numbers of 
.
Which according to the given options , Option 3 is correct.
Step-by-step explanation:
- The area of the blue square will always equal the sum of the area of the orange and red rectangles
The pythagorian theorem:
a²+b² = c²
now let a be the side of the red triangle and b the side of the orange one
so a² is the area of the red triangle and b² is the area of the orange one
Let c be the side of the blue rectangle
so c² is the area of it
then what we concluded is right
- the hypotenuse is the blue side since it is the larger one
Hey there!
When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.
Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).
That can be simplified to 4x + 335.
So, (f + g)(x) = 4x + 335.
Let's plug 2 in for x and solve.
(f + g)(2) = 4(2) + 335
Multiply.
(f + g)(2) = 8 + 335
Add.
(f + g)(2) = 343
The x value is consistent for the values of both equations, in both x is defined as the number of hours spent exercising.
So, (f + g)(2), which is 343, is the amount of calories burned and the calorie deficit on a diet when 2 hours are spent exercising.
Hope this helps!
