Answer:

A) 2

Step-by-step explanation:

We already know that [tex]i[/tex] equals -1, so we can substitute that into the expression.

[tex](\sqrt{3} +(-1))(\sqrt{3} -(-1))\\(\sqrt{3} -1)(\sqrt{3}+1)[/tex]

Now we can use the distributive property to solve the rest

[tex](\sqrt{3} -1)(\sqrt{3}+1)\\\sqrt{3} *\sqrt{3} +\sqrt{3} -\sqrt{3}-1\\ 3+0-1\\=2[/tex]

Answer:

x=7

Step-by-step explanation:

2x+3(x-5)=20

2x+3x-15=20

5x-15=20

5x=35

x=7

Answer:

x = 5

Step-by-step explanation:

2x + 3(x - 5) = 20

simplify

5x - 5 = 20

get the variable and the number on different sides

5x - 5 + 5 = 5x

20 + 5 = 25

5x = 25

now divide each side by 5

5x / 5 = x

25 / 5 = 5

x = 5

Sale Tax: 5.00% or $0.70

Answer:

14.12

Step-by-step explanation:

0.05 is also known as 5%

14.07+0.05=14.12

The amount that Susan actually have to pay should be considered as the $1,332.

Since the purchase price of the computer is $1,200

And, the sales tax rate is 11%

So here the total amount be like

= $1,200 + 11% of $1,200

= $1,200 + $132

= $1,332

hence, The amount that Susan actually have to pay should be considered as the $1,332.

9-18-141

Step-by-step explanation:

9-18= -9

-9-141= (-150)

Answer:

Quest 5. No, 2^4 = 16, 2.4 =2 x 4 = 8.

Quest 6. let No. of cells = Nc, let No. of Hours = Nh.

then Nc = (6hrs x 2cells)/1hr = 12 cells.

if 1,024 cells, then

Nh = (1hrs x 1,024cells)/2hrs = 512 hrs.

Quest 7. No, cos 10^7 is only 10,000,000, so 39 & 10 million are not any way equal.

Quest 8. 1 = 1^3, 8 = 2^3, 27 = 3^3, 1 = 1^3, 64 = 4^3, 125 = 5^3,

Quest 9. 2^8 = 2 x 2 x 2 x 2 x 16 = 256, this cos 256 is a product of 8, 2s & there are 4, 2s in 16.

so altogether its all 8, 2s.

Answer:

x = 46 via Angle Addition postulate (2x+4 = 60 + x-10 )

Step-by-step explanation:

Answer:

a. f(1) = -4

b. One value of x for which f(x) = -1 : 2 (or -2)

Step-by-step explanation:

a. To find f(1), we would have to find what the value of the function would be when x = 1. By using the given graph, we can find the f(1) by finding what the y-value is when x = 1. Looking at the graph, we can see that when x = 1, y = -4. Thus, f(1) = - 4.

b. Now we are also asked to find one value of x for which f(x) = -1. In other words, what values of x would make the value of the function equal to -1? We can find values of x for which f(x) = -1 by using the graph and seeing for which x-values would the y-value be -1. We can see that y = -1 at x = -2 and x = 2. So the values of x at which f(x) = -1 are -2 and 2. You can choose either one of these values.

Answer:

$10 - $2x = A

Step-by-step explanation:

The equation for A, in terms of x, represents the amount of money remaining on the card after buying x cups of coffee is $10 - $2x = A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Isaiah was given a gift card for a coffee shop. Each morning, Isaiah uses the card to buy one cup of coffee. The original amount of money on the gift card was $10 and each cup of coffee costs $2.

The equation will be written as below,

$10 - $2x = A.

A is the amount of money remaining on the card

x is cups of coffee.

Therefore, the equation for A, in terms of x, represents the amount of money remaining on the card after buying x cups of coffee is $10 - $2x = A.

Answer:

They need more than 2.5 inches.

Step-by-step explanation:

average = 5.3

June: 6.3

July: 7.1

August: x

The average of the amounts for June, July, and August is

(6.3 + 7.1 + x)/3

To exceed the average, the average must be greater than 5.3.

(6.3 + 7.1 + x)/3 > 5.3

Multiply both sides by 3.

6.3 + 7.1 + x > 15.9

x + 13.4 > 15.9

Subtract 13.4 from both sides.

x > 2.5

Answer: They need more than 2.5 inches.
