Find the value’s of x given that f(x) = x^2 - 2x - 3 and f(x) = 5

Answers

Answer 1

Answer:

4 and - 2

Step-by-step explanation:

f ( x ) = x^2 - 2x - 3

f ( x ) = 5

x^2 - 2x - 3 = 5

x^2 - 2x - 3 - 5 = 0

x^2 - 2x - 8 = 0

x^2 + 2x - 4x - 8 = 0

x ( x + 2 ) - 4 ( x + 2 ) = 0

( x - 4 ) ( x + 2 ) = 0

x - 4 = 0

x = 4

x + 2 = 0

x = - 2

x has 2 values,

x = 4, - 2

If the $3.80 large popcorn was on sale for 25% off, what is the discounted price?

Answers

Answer:

2.85

Step-by-step explanation:

You will pay $2.85 for a item with original price of $3.80 when discounted 25%. In this example, if you buy an item at $3.80 with 25% discount, you will pay 3.80 - 0.95 = 2.85 dollars.

Answer:

2.85

Step-by-step explanation:

25%= 100÷25=4

3.80÷4 =0.95

25% of 3.80 = 0.95

discounted price:

3.80-0.95

=2.85

How is the product related to the factor? 3/5 x 6/7 The product is less than 3/5 The product is greater than 6/7 The product is greater than 3/5 The product is equal to 3/5

Answers

Answer: The product is less than 3/5

Step-by-step explanation:

To know the solution, we have to multiply 3/5 by 6/7. This will be:

= 3/5 × 6/7

= 18/35

Note:

18/35 to decimal = 0.5143

3/5 to decimal = 0.60

6/7 to decimal = 0.8571

Therefore, we can see that the product is less than 3/5.

Step-by-step explanation: Hope this help :D

Answer:

[tex]{k = - \frac{363}{8} \: \: \: or \: \: - 45 \frac{3}{8} } \\ [/tex]

Step-by-step explanation:

-8(k + 46) = -5

Expand the terms on the right

-8k - 368 = - 5

Add 368 to both sides of the equation

- 8k - 368 + 368 = - 5 + 368

- 8k = 363

Divide both sides by - 8

[tex] \frac{ - 8k}{ - 8} = - \frac{363}{8} \\[/tex]

We have the final answer as

[tex]k = - \frac{363}{8} \: \: \: or \: \: - 45 \frac{3}{8} \\ [/tex]

Answer:

The orginial angle is a right angle (however, the pair of angles would be classified as complementary angles); the value of x is 28.

Step-by-step explanation:

It's important to note that a right angle is always 90°.

90 - 56 = 34

Set up an equation to solve for x:

34 - 6 = x

34 - 6 = 28

28 = x

Now, check if the answer is correct.

Add up both angles' measurements:

56 + (28 + 6) = 90
