Answer: 3/5
Step-by-step explanation:
Probabilty of blue tiles: 12/20 =3/5
Probability of letter b tiles: 10/20= 1/2
How to get the denominator?
4+6=10
2+8=10
10+10=20
Answer:
x = 5 and -2
Step-by-step explanation:
Given the function of x to be;
f(x) = (x-5)(x+2)/x+1
The value of x that will make the function zero can be calculated for by equating the given function to zero first to have;
If f(x) = 0, then;
(x-5)(x+2)/x+1 = 0
Cross multiplying;
(x-5)(x+2) = 0
(x-5) = 0 and x+2 = 0
x = 5 and x = -2
The value of x that will make the function zero is therefore 5 and -2
A
substitute x = 3h into f(x)
f(3h) = 2(3h)² + 3(3h) - 4 = (2 × 9h²) + 9h - 4 = 18h² + 9h - 4

<span>Simplifying
9x + -2y = 19
Solving
9x + -2y = 19
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
9x + -2y + 2y = 19 + 2y
Combine like terms: -2y + 2y = 0
9x + 0 = 19 + 2y
9x = 19 + 2y
Divide each side by '9'.
x = 2.111111111 + 0.2222222222y
Simplifying
x = 2.111111111 + 0.2222222222y</span>
