All you have to do is add the number to the variable you need to. It works the same for subtraction instead you will put y-14 or any variable and number that is needed to subtract from it and remember when they say a number more than a variable it is + that number if they say a number less than a variable it is - that number .

Find the slope of the line passing through the points (-9,4) (8,4)

Answers

Answer:

slope = 0

Step-by-step explanation:

1) Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex], to solve for the slope. Use the x and y values of the given points, substitute them into the formula, and solve like so:

[tex]m = \frac{(4)-(4)}{(8)-(-9)} \\m = \frac{4-4}{8+9} \\m = \frac{0}{17} \\m = 0[/tex]

Thus, the slope is 0.

Tyrese wants to buy baseball cards. They cost $5.00 per pack. There is a 25% discount before tax if 10 or more packs are purchased. Sales tax is 7%. If Tyrese buys 15 packs of cards, how much does he pay?

Answers

Answer:

72.225 $

Step-by-step explanation:

The price per pack: 5.00 $

When the amount of packs is > 10 :

90 % * 5 $ = 4.50 $ before tax.

The price of 15 packs:

4.50 $ * 15 = 45 + 22.5 = 67.5 $ before tax.

After tax:

107 % * 67.5 $ = 72.225 $ after tax.

A warehouse has shelves that can hold 8, 12, or 16 skateboards. each shelf has sections holding the same number of skateboards. what is the greatest number of skateboards that can be put in a section

Answers

Answer:

Step-by-step explanation:

To solve this you need the find the GCF or the greatest common factor.

To do this just look through the numbers to find the highest factor for all three.

For 8, 12, and 16 it would be 4.

4 goes into all of them and no number higher can do this

So your answer would be 4.

Mia is factoring the polynomial x2 + 4x – 12. She uses the steps shown.

A 2-column table with 4 rows. The first column has no label with entries Step 1, Step 2, Step 3, Step 4. The second column is labeled x squared + 4 x minus 12 with entries x squared + 6 x minus 2 x minus 12, (x squared + 6 x ) minus (2 x + 12), x(x + 6) minus 2(x + 6), (x + 6)(x + 2).

In which step did Mia make an error?
Step 1
Step 2
Step 3
Step 4

Answers

Mia's error is in step 4

What is factorization?

Factorization involves splitting a function into several factors

The steps in factorizing the expressions are:

Step 1: x^2 + 6x - 2x -12

Step 2: (x^2 + 6x) - (2x + 12)

Step 3: x(x + 6) - 2(x + 6)

Step 4: (x + 6)(x + 2)

From the step 3 to step 4, the resulting expression should be

(x + 6)(x - 2)

However, the step 4 of the expression is (x + 6)(x + 2)

The expected expression and the actual expression in step 4 are different.

Hence, Mia's error is in step 4

y = x² +1,x>0
find the inverse

Answers

Answer:

The inverse of x² +1 is:

[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Step-by-step explanation:

Given

y = x² + 1, x>0

We know that A function g is the inverse of a function f if for y = f(x), x = g(y)

y = x² +1

Replace x with y

x = y² + 1

solve for y

y² = x - 1

Taking square root

[tex]y=\:\sqrt{x-1},-\sqrt{x-1}[/tex]

Thus, the inverse of x² +1 is:

[tex]\sqrt{x-1},\:-\sqrt{x-1}[/tex]

Answers

Answer: The answer is 37.

Step-by-step explanation: i took test

The length of the hypotenuse, x is 37.

The correct option is B.

What is Pythagoras theorem?

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A Pythagorean triple (12, 35, x).

Applying the Pythagoras theorem,

The length of the hypotenuse, x,

x = √(35)² + (12)²

x = √1369

x = 37

Therefore, the value of x is 37.
