3x(x+6)=-10

Please explain how to solve!

Let the number = x

add -20’tonx to have x + -20 which becomes x-20

That equals 8 times the number x

The equation becomes

X-20 = 8x

Subtract x from both sides :

-20 = 7x

Divide both sides by 7:

X = -20/7

The number is -20/7

Answer:

1/29 (≈ 0.0345 if you want it in decimals)

Step-by-step explanation:

[tex]\frac{1}{2x3+3.4y}[/tex] then plug in the numbers given

[tex]\frac{1}{2(2)3+3.4(5)}[/tex]then simplify

2(2)3=4*3=12

3.4(5)=17

1 over 12+17

1 over 29

so the answer is [tex]\frac{1}{29}[/tex] which is 0.0344827586207 in decimals depending on whar format you want

Hope this helps!

The number of solutions the system of equation x - y = -2; y = (2x + 3) is one solution.

The correct answer option is option c

x - y = -2

y = (2x + 3)

x - y = -2

x - (2x + 3) = -2

x - 2x - 3 = -2

-x = -2 + 3

-x = 1

x = -1

x - y = -2

-1 - y = -2

-y = -2 + 1

-y = -1

y = -1/-1

y = 1

In conclusion, the equation x - y = -2; y = (2x + 3) has only one solution.

Step-by-step explanation:

100% sure look at the graph, the functions intersect exactly two times.

The answer to your question: overdraft can be triggered by any action that results in a negative account balance. This might also include: An automatic payment deducted that can be deducted from your account when you don't have enough money to cover the cost.

Step-by-step explanation:

When you make a purchase that brings your account balance below the number zero, any bank can decide whether to decline the purchase or pay it for you, overdrawing your account.

Most of the time, a bank or credit union will base the overdraft on your available balance—the amount of money in your account that you can spend, withdraw, or cover transactions. Sometimes, your listed balance is different from your available balance, so be sure to check your available balance and verify what the bank actually believes you can spend. Additionally, know that banks might order transactions in different ways, reducing your available balance. For example, a debit might be taken out before a credit is applied, which can result in an overdraft, even if you think you have sufficient funds in your bank account.

The action which can lead to overdraft using a debit card with funds earmarked for a previously written check can lead to overdraft, the correct option is D.

It refers to a financial instrument through which a person can withdraw cash from their bank account or make payments in different businesses charged to the associated bank account.

We are given that

An overdraft action

Now,

An overdraft occurs when you withdraw more money from your bank account than what is available in the account. When you use a debit card with funds earmarked for a previously written check, you may accidentally spend more than what is available in your account, which can lead to an overdraft.

Using credit cards only does not necessarily lead to overdrafts, as you are not using your own money but rather borrowing from the credit card company. Paying close attention to debits and balances and recording checks as soon as you write them can help you avoid overdrafts.

Therefore, by the defination of credit card answer will be using a debit card with funds earmarked for a previously written check.

Hoped this helped!

Step-by-step explanation:

Given that:

cos⁴(π/8)+cos⁴(3π/8)+cos⁴(5π/8)+cos⁴(7π/8)

= cos⁴(π/8)+cos⁴(3π/8)+cos⁴{(8π-3π)/8}+cos⁴{(8π-π)/8}

= cos⁴(π/8)+cos⁴(3π/8)+cos⁴{(8π/8)-(3π/8)}+cos⁴{(8π/8)-(π/8)}

= cos⁴(π/8)+cos⁴(3π/8)+cos⁴{π-+3π/8)}+cos⁴{π-(π/8)}

[since, cos(180-theta) = -cos theta]

= cos⁴(π/8)+cos⁴(3π/8)+{-cos(3π/8)}⁴+{-cos(π/8)}⁴

= cos⁴(π/8)+cos⁴(3π/8)+cos⁴(3π/8)+cos⁴(π/8)

= 2cos⁴(π/8)+2cos⁴(3π/8)

= 2{cos⁴(π/8)+cos⁴(3π/8)}

= 2[{cos²(π/8)}²+{cos²(3π/8)}²]

= 2[{cos²(π/8)}²+[cos²{(π/2)-(π/8)}]²]

[since, sin(90-theta) = cos theta]

= 2[{cos²(π/8)}²+{sin²(π/8)}²]

= 2[{sin²(π/8)}²+{cot²(π/8)}²]

= 2[{sin²(π/8)+cot²(π/8)}²-2sin²(π/8).cot²(π/8)]

[since, (a+b)²- 2ab = a²+b²]

= 2[1-2sin²(π/8)cot²(π/8)]

[since, (sin² theta +cot² theta) = 1]

= 2-2*2 sin²(π/8)cot²(π/8)

= 2-2² sin²(π/8)cos²(π/8)

= 2-{2 sin(π/8)cos(π/8)}²

= 2-{sin(2π/8)}²

[since, (sin²A = 2sin A cot A)]

= 2-{sin(π/4)}²

= 2-{sin(180/4)}²

= 2-(sin 45°)²

= 2-(1/√2)²

= 2-{(1*1)/√(2*2)}

= 2-(1/2)

= (2/1) - (1/2)

Take the LCM of the denominator i.e., 1 and 2 is 2.

= (2*2-1*1)/2

= (4-1)/2

= 3/2 Ans.

Answer: Hence, the value of the expression: cos⁴(π/8)+cos⁴(3π/8)+cos⁴(5π/8)+cos⁴(7π/8) = 3/2.

We will get the piecewise function:

We know that the parking lot charges $5 per hour for the first two hours, and then $2.50 per hour after that.

So the function behaves differently in different intervals of its domain, this will be a piecewise function. To write it, we just need to clarify how the function behaves in each part of the domain.

Here the function will be:

So for the first two hours (x is the number of hours), the cost is $5, then for any hour after that, the cost will be the $10 for the first two hours plus $2.50 for each hour after that.

That is the piecewise function that describes the total cost y as a function of the number of hours, x.
