Answer:

Step-by-step explanation:

your basically multiplying everything in the first parenthesis by everything in the second parenthesis

(x + 4y + z)(x - 7y) =

x(x - 7y) + 4y(x - 7y) + z(x - 7y) =....keep in mind, 4yx is the same as 4xy

x^2 - 7xy + 4xy - 28y^2 + zx - 7zy....combine like terms

x^2 - 3xy - 28y^2 + zx - 7zy <---- your answer

this is the distributive property

<span><span><u>Answer</u>
</span><span>1/55

</span><span><u>Explanation</u>
</span><span>The probability of an event is a chance of it happening. It is calculated as;
Probability =(fouvarable outcome)/(total outcome)
Since we are finding the probability of no girl will be chosen, it is like finding the probability of choosing 3 boys.
The probability of choosing the first boy =4/12
The probability of choosing the second boy =3/11
The probability of choosing the third boy =2/10
The probability of choosing the 3 boys will be,
=4/12×3/11×2/10
=24/1320
=1/55

If 2 - 4(y + 1) = 2y + 16, what is the value of y?<br> Show all work, please.
VladimirAG [237]

Answer:

y = -3

Step-by-step explanation:

2 - 4(y + 1) = 2y + 16

2 - 4y - 4 = 2y + 16

2 - 4 = 6y + 16

- 2 = 6y + 16

- 18 = 6y

-3 = y

You have $6,500 to deposit. If you deposit the money in a savings account at your local bank, you will earn 1.45% annual interes
FinnZ [79.3K]
The amount earned from the local account must be greater than that of the online account.
Amount from local account = 6,500(1.0145)ⁿ
Amount from online account = 6,500(1.0225)ⁿ - 4x
Where n is the number of years and x is the number of ATM withdrawals.

6,500(1.0145)ⁿ > 6,500(1.0225)ⁿ - 4x
4x > 6,500[(1.0225)ⁿ - (1.0145)ⁿ]; n = 1
x > 13
The number of withdrawals must exceed 13.

The answer is C.

Plz help me!!!! I really need help!!!! <br><br> Solve for x
Delvig [45]

Answer:

try 35

Step-by-step explanation:

wow rly? delete my answer?

basically the angle 35 is on a parallel line which means that the angle opposite must be 35 as well since they are vertically opposite angles which makes them the same

then you use the alternate angles to work out the angle below 72 which will be 35

then lastly x should be 35 since vertically opposite angles are the same
