Answer:
The domain is all real numbers less than or equal to two-third
Step-by-step explanation:
<u><em>The question in English is</em></u>
Determine the domain of the function f :D→R, 
we know that
The radicand of the function must be greater than or equal to zero
so

Solve the inequality for x
subtract 2 both sides

Multiply by -1 both sides

Divide by 3 both sides

The solution is the interval ----> (-∞,2/3]
therefore
The domain is all real numbers less than or equal to two-third
Answer:
$290
Step-by-step explanation:
We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.
Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.
Thus;
P(x) for expensive sofa = 1/5
P(x) for sofa in sale advertisement = 4/5
Thus, expected value is;
E(X) = (1/5)450 + (4/5)250
E(x) = 90 + 200
E(x) = $290
Answer:
M = -2
Step-by-step explanation:
-17 + 62 = -5 (3M - 3) Distribute -5 into the parentheses and combine like terms
45 = -15M + 15 Subtract 15 from both sides
30 = -15M Divide 15 from both sides
M = -2
Answer:
1084.83932813 which you would round to 1085
Answer
y = 2(x - 8)(x + 2)
Step-by-step explanation:
A(x - 8)(x + 2)
A × -8 × 2 = -32
-16A = -32
A = 2
y = 2(x - 8)(x + 2)
