Answer:
Step-by-step explanation:
total sides = 6
p (rolling a 1) =
p (rolling a 2) =
Note:
or - add
and - multiply
∴
∴
hence, p (rolling a 1 or 2) =
Answer:
x = 10
y = 4
Step-by-step explanation:
5x-4y=24 ------>( 1 )
-2x+7y=12 ------>( 2 )
( 1 ) × 2
(2) × 5
10x - 8y - 10x + 35y = 48 + 60
<u>27y</u><u> </u>= <u>108</u><u> </u>
27 27
y= 4
5x - 4× 4 = 24
5x - 16 = 24
x = 10
If we substitute 13 to f(x) and get a value for x, then the two equations will intersect. So,
f(x) = x^2 + 6x +10
13 = x^2 + 6x+ 10
x^2 + 6x - 3 = 0
Solving the quadratic equations:
The roots of the equation is
x = 0.4641 and
x = -6.4541
Therefore, the line will intersect with the quadratic function.
