find f'(x)of f(x)=x^2-6x​

Answer:

1. y=20x+100(this is the equation)

2. 260(this is how much he has after 8 weeks)

Step-by-step explanation:

Saving is the remaining money after all the expenditure. Thus, Johnny's total savings after 8 weeks will be $[tex]260[/tex].

Johnny is saving money to buy a Nintendo Switch.

He already saved the amount of $100.

He plans to save from his allowance each week is $20

The equation that represents the total savings is mentioned below.

[tex]y=20x+100[/tex]

Therefore, Substitute the values and solve them further.

[tex]y= (20\times 8) + 100[/tex]

[tex]y= 260[/tex]

Hence, Johnny's total savings after 8 weeks will be $[tex]260[/tex]

Answer:

C, first I'm not sure if it's correct, but hear me out.

Step-by-step explanation:

If we already know that B=34 we need to find out the rest.

B=50 (Estimated)

D=45 (Estimated)

34+50+45

34+50=84+45=129, 129 estimated=130, and since their is no answer choice but C it should be C, I could be very wrong though.

Answer:

5 , |-5|

Step-by-step explanation:

2 of the above are the absolute value of 5

The two numbers whose absolute value is 5 are 5 and -5.

Numbers whose absolute value is 5 can be both positive and negative.

The absolute value of a number is its distance from zero on the number line, so any number that is 5 units away from zero in either the positive or negative direction will have an absolute value of 5.

Here are the numbers whose absolute value is 5:

5 (positive 5, because it's 5 units to the right of zero)

-5 (negative 5, because it's 5 units to the left of zero)

Hence, 5 and -5  are the two numbers whose absolute value is 5.

Answer:

5ab^2-6a^2b+a^3-2b+2a

Step-by-step explanation:

The simplified expression of  expression  (a – b)(a² – 5ab + 2) is a³ – 6a²b + 5ab² + 2a – 2b

An expression is combination of variables, numbers and operators.

To simplify the expression (a – b)(a² – 5ab + 2), we need to apply the distributive property, which states that:

(a + b)(c + d) = ac + ad + bc + bd

Using this property, we can multiply the two binomials as follows:

(a – b)(a² – 5ab + 2) = a(a² – 5ab + 2) – b(a² – 5ab + 2)

Now we can distribute the terms of each binomial:

= a³ – 5a²b + 2a – a²b + 5ab² – 2b

Simplifying the terms, we can combine like terms:

= a³ – 6a²b + 5ab² + 2a – 2b

Therefore, the simplified expression is a³ – 6a²b + 5ab² + 2a – 2b

Step-by-step explanation:

Start with the small triangle on the right:

   35 + 96 + x = 180

   x = 49

Ah, you already have that.  Nice!

Now move to the biggest triangle:

   x + 77 + (35+y) = 180

but x = 49, so

   49 + 77 + 35+y = 180

   y = 19

Step-by-step explanation:

Adding the matrices, it is found that the values are: [tex]a = -5, b = 8, c = 11, d = -3[/tex]

The values of a, b, c and d is determined by the addition of matrices P and Q, that is:

[tex]P + Q = \left[\begin{array}{cc}a&c\\b&d\end{array}\right][/tex]

We have that the matrices are:

[tex]P = \left[\begin{array}{cc}-3&6\\10&-4\end{array}\right][/tex]

[tex]Q = \left[\begin{array}{cc}-2&5\\7&1\end{array}\right][/tex]

Then:

[tex]P + Q = \left[\begin{array}{cc}-3&6\\10&-4\end{array}\right] + \left[\begin{array}{cc}-2&5\\7&1\end{array}\right] = \left[\begin{array}{cc}-3-2&6+5\\1+7&-4+1\end{array}\right] = \left[\begin{array}{cc}-5&11\\8&-3\end{array}\right][/tex]

Finally:

[tex]\left[\begin{array}{cc}-5&11\\8&-3\end{array}\right] = \left[\begin{array}{cc}a&c\\b&d\end{array}\right][/tex]

Thus, the values are:

[tex]a = -5, b = 8, c = 11, d = -3[/tex]

If the price of the shirt was reduced from $15 to $9, the percentage reduction in price is 40%

The price of the shirt was reduced from 15 dollars to 9 dollars. Therefore, the percentage reduction can be found as follows:

15 - 9 = 6 dollars

Therefore,

percentage reduction = 6 / 15 ×100

percentage reduction= 600 / 15

percentage reduction = 40%

Therefore, the percentage reduction in price is 40%.
