Answer:
5 +40x
Step-by-step explanation:
Distributive property:a*(b +c) =(a*b) + (a*c)
-3 - 8( -5x - 1) = -3 + (-5x)*(-8) + (-1) * (-8)
= -3 + 40x + 8
= -3 + 8 + 40x {combine like terms}
= 5 + 40x
A new secretary has been given n computer passwords, only one of which will permit access to a computer file. Because the secretary has no idea which password is correct, he chooses one of the passwords at random and tries it. If the password is incorrect, he discards it and randomly selects another password from among those remaining, proceeding in this manner until he finds the correct password. What is the probability that he obtains the correct password on the second try? The third try?
Answer:
The answer is "[tex]\bold{\frac{1}{n}}[/tex]"
Step-by-step explanation:
Although n passwords were available and any time a wrong password is deactivated. Throughout the second try, if the secretary finds the right password, its input during the first attempt should be incorrect. Therefore, the likelihood is:
[tex]\to Pr= \frac{n-1}{n} \times \frac{1}{n-1} =\frac{1}{n}[/tex]
If n passwords were accessible and any time the wrong password is deactivated. Unless the delegate finds the right password on the three trials, the input should be incorrect during the first and second trials. Consequently, the likelihood is:
[tex]\to Pr= \frac{n-1}{n} \times \frac{n-2}{n-1} \times \frac{1}{n-2} =\frac{1}{n}[/tex]

Given m || n, find the value of x and y.
answer:
y = 35
x = 35
explanation:
y and 35 are vertical angles therefore are equal.
x and 35 are alternate interior angles therefore are equal.
if correct, please mark the brainliest :)
Answer:
Both values equal 35 degrees
Step-by-step explanation:
This is because y and the angle that shows 35 degrees are vertical angles, meaning they have the same measurements. x and y are corresponding angles, which means they also have the same measurements.
Hope this helps :)
1) Find all the critical numbers of the given function
f(x) = X 1 - 4
-
3
Answer:
(0,-4)
Step-by-step explanation:
Given
[tex]f(x) = x^\frac{1}{3} - 4[/tex]
Required
Determine the critical numbers
[tex]f(x) = x^\frac{1}{3} - 4[/tex]
Differentiate:
[tex]f'(x) = \frac{1}{3}x^{\frac{1}{3} - 1}[/tex]
[tex]f'(x) = \frac{1}{3}x^{-\frac{2}{3}}[/tex]
Equate to 0
[tex]f'(x) = \frac{1}{3}x^{-\frac{2}{3}} = 0[/tex]
[tex]\frac{1}{3}x^{-\frac{2}{3}} = 0[/tex]
Multiply through by 3
[tex]3 * \frac{1}{3}x^{-\frac{2}{3}} = 0*3[/tex]
[tex]x^{-\frac{2}{3}} = 0[/tex]
[tex]x = 0[/tex]
Substitute 0 for x in [tex]f(x) = x^\frac{1}{3} - 4[/tex]
[tex]f(0) = 0^\frac{1}{3} - 4[/tex]
[tex]f(0) = 0- 4[/tex]
[tex]f(0) = - 4[/tex]
Hence, the critical point is: (0,-4)

If 6(2x+1) is equal to -36-2x, what is the value of 3x
Answer:
The value of 3x is -9
Step-by-step explanation:
Given Equation
[tex]6(2x + 1) = - 36 - 2x[/tex]
Step 1
Distribute 6 in the expression.[tex]12x + 6 = - 36 - 2x[/tex]
Step 2
Combine like terms and solve the equation for x-term[tex]12x + 2x = - 36 - 6 \\ 14x= - 42 \\ x = \frac{ - 42}{14} \longrightarrow \frac{ - 3}{1} \\ x = - 3[/tex]
But we want to know what is the value of 3x.
Step 3
Substitute the value of -3 in 3x.[tex]3x = 3( - 3) \\ 3x = - 9[/tex]
Hence, the value of 3x is -9

Jonathan leans three playing cards against each other to form a triangle. He uses three more playing cards from the same deck to form a second triangle. Which statement is true?
1. In order to determine if the two triangles are congruent Jonathan must measure all three interior angles.
2. In order to determine the two triangles are congruent Jonathan must measure one interior angle .
3. The two triangles cannot be congruent because sides cannot be used to prove congruency.
4. The two triangles must be congruent because the corresponding sides in both triangles are congruent
Answer: Michelle it’s 4
Step-by-step explanation: they are from the same deck

Question 6 of 10
Assume ABC = ADEF. If IZA= 70° , m B = 47° , and m2 C = 63°, what is
the measure of ZF?
Answer:
63° is the answer according to me
The value of measure of angle F is,
⇒ ∠ F = 63°
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Triangle ABC and DEF are congruent.
Hence, Their corresponding angles are same.
So, We get;
⇒ ∠ A = ∠X
⇒ ∠B = ∠Y
⇒ ∠C = ∠Z
Here, ∠C = 63°
Hence, The value of measure of angle F is,
⇒ ∠ F = 63°
Thus, The value of measure of angle F is,
⇒ ∠ F = 63°

Tim has a friend, John, across the world he wants to transfer 1000$ to. However, his bank charges a 0.3% fee on the value of every transfer. Tim wants John to receive 1000$ after the fees, which means that Tim needs to send more than 1000$ for him to cover the fees the bank charges. How much should Tim send so that John receives 1000$ in his account after fees?
Answer:
1003
Step-by-step explanation:
as Tom has to sent amount of money =
1000 (amount of money that john needs) + 0.3%*1000 (fee) = 1000+ 3 = 1003

Step-by-step explanation:
Let's close the top part of the picture to make a parallelogram.
A parallelogram's four angles at each corner MUST be equal to 360 degrees.
Another property of a parallelogram is the opposite angles are congruent, meaning they're equal.
So, using these properties, we can now solve for a.
