Divide 0.50 / 250 PLS HELP I GIVE 20 POINTS

Answer:

3 + 5i

Step-by-step explanation:

Given

- 2i + (9 - 3i) - (6 - 10i) ← distribute parenthesis

= - 2i + 9 - 3i - 6 + 10i ← collect like terms

= 3 + 5i

Options:

[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]

[tex]B.\ (-1, 1)[/tex]

[tex]C.\ (4, 16)[/tex]

[tex]D.\ (\frac{1}{2}, \frac{1}{4})[/tex]

Answer:

[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]

Step-by-step explanation:

Given

[tex]y = x^2[/tex]

Required

Determine which of the given points is not true

[tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex]

Here

[tex]x = \frac{3}{2}[/tex] and [tex]y = \frac{9}{2}[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]\frac{9}{2} = (\frac{3}{2})^2[/tex]

[tex]\frac{9}{2} = \frac{3}{2}*\frac{3}{2}[/tex]

[tex]\frac{9}{2} \ne \frac{9}{4}[/tex]

Both sides of the equation are not equal. Hence, this point do not line on the curve

[tex]B.\ (-1, 1)[/tex]

Here

[tex]x = -1[/tex]  and [tex]y = 1[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]1 = (-1)^2[/tex]

[tex]1=1[/tex]

Both sides of the equation are equal. Hence, this point line on the curve

[tex]C.\ (4, 16)[/tex]

Here

[tex]x = 4[/tex]  and [tex]y = 16[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]16 = 4^2[/tex]

[tex]16 = 16[/tex]

Both sides of the equation are equal. Hence, this point line on the curve

[tex]D.\ (\frac{1}{2}, \frac{1}{4})[/tex]

Here

[tex]x = \frac{1}{2}[/tex]  and [tex]y = \frac{1}{4}[/tex]

Substitute these values in [tex]y = x^2[/tex]

[tex]\frac{1}{4} = (\frac{1}{2})^2[/tex]

[tex]\frac{1}{4} = \frac{1}{2}*\frac{1}{2}[/tex]

[tex]\frac{1}{4} = \frac{1}{4}[/tex]

Both sides of the equation are equal. Hence, this point line on the curve

From the calculations above; only [tex]A.\ (\frac{3}{2}, \frac{9}{2})[/tex] do no lie on the curve

Answer:

The better deal is 8 for $7.50

4 of pack one=$25

2 of pack two=$15

Spent altogether= $40

Answer:

Which is the better deal? Pack of 8 is a better deal.

Buy 4 of Pack One: $24.40

Buy 2 of Pack Two: $11.90

How much did you spend altogether? $36.30

Step-by-step explanation:

Let's start with the Swag Bags. To figure out if something is a good price, divide the items inside of it by the price so you can get the $ per item and compare.

[tex]\frac{6.25}{6}[/tex] = $1.04 per item for Pack of 6

[tex]\frac{7.50}{8}[/tex] = $.94 per item for Pack of 8

Generally, saying "which item is the better deal" refers to which price per item is cheaper. In this case, Pack of 8 is a better deal.

Now, goodie bags.

Pack one costs $6.10 while Pack two costs $5.95.

"Buy 4 of Pack One: $" is asking for the price of 4 Pack Ones. To do this, you simply multiply the pack one price by 4, since you are buying 4 of them.

4 * 6.10 = $24.40

Same idea for Pack Two, just different price and different amount.

2 * 5.95 = $11.90

How much did you spend altogether? Add the total values for both goodie bag packs.

$24.40 + $11.90 = $36.30

Answer:

12 days

Step-by-step explanation:

4x3=12

Answer:

5 yes

7 yes

9 no

Step-by-step explanation:

(4*7)^x is 28 which is greater than 0 and not equal to one.

Same with 7

9 has a negitive 5 being multiplied to 9 which leads it to being -45^x which is less than zero

Answer:

x=31, x=31, x=21.

Step-by-step explanation:

So for number 33, we see that 2x+28=90 degrees so you just simplify the equation to 2x=62, x=31.

For number 34, we see that 4x+56=180 (flat line), so we simplify the equation again and get 4x=124, x=31 degrees.

For number 35, according to the vertical angle theorem, 43=2x+1, so we simplify that too and we get 42=2x, 21=x, x=21.

Answer:

m∠1 = 148°  and m∠2 = 32°

Step-by-step explanation:

m∠1 + m∠2 = 180°  (supplementary angles)

4x° + (x - 5)° = 180  (substitution)

4x + x - 5 = 180

5x - 5 = 180

5x = 185

x = 37

m∠1 = 4(37)° =148°  and m∠2 = (37 - 5)° = 32°

The price of the set of dishes is $190.

You are getting 90% off.

$190 x 90% = $171

$190 - $171 = $19

Bryant will pay $19 for the set of dishes.

48=y+5y

pretend that there is a 1 in front for the y

48=1y+5y

add the like terms first

1y+5y=6y

48=6y

divide both sides by 6 to get y by itself

48/6=6y/6

8=y

answer:

y=8

Answer:

y = 8

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

48 = y + 5y

Step 2: Solve for y

Step 3: Check

Plug in y into the original equation to verify it is a solution.

Here we see that 48 does indeed equal 48.

∴ y = 8 is a solution of the equation.

Should be 10 because each time you multiply 10 in the graph, you can see how it goes up by 10

Answer: 2x+y+11=0

Step-by-step explanation:

The equation of given line is x-2y-2=0

Slope of given line is (m1)= - coefficient of x÷coefficient of y

m1= -1÷-2 =1÷2

Let slope of required line be m2.

Since the two lines are perpendicular,

So,

m1×m2= -1

or, 1÷2×m2 = -1

m2 = -2

The required line is passing through (4,-3)

Using two points slope form,

y-y1 = m(x-x1)

or, y-(-3)= -2(x+4)

or, y+3= -2x -8

or, 2x+y+3+8 = 0

2x+y+11 = 0 which is required equation of line.

Answer:

2/12 :) or even 1/6 if you simplify

Step-by-step explanation:

Answer:

2/12

Step-by-step explanation:

1 dice = 1/6 × 2 because we have to die but this is different from normal multiplication you do the probability of finding 2 in both which is 1+1 over the total number which is 6+6. Therefore your answer would be 2/12

Answer:

Exponential growth

4%

12

Step-by-step explanation:

Given the function :

​f(n) = 12(1.04)^n​

Part A: Is this a growth or decay exponential function?

The equation above is usually generally represented as :

F(n) = A(1 ± r)^n

Where F(n) = final amount after n years ; r = rate ; n = number of years

The function Given above is thus :

F(n) = 12(1 +0.04)^n

This is an exponential growth function because of the negative rate (+ 0.04)

Part B: What is the growth or decay percentage for this function

From the equation :

F(n) = A(1 + r)^n ; r = rate

Comparing F(n) = 12(1 +0.04)^n ; r = 0.04 = 0.04*100% = 4%

Part C: What does the y-intercept of the graph of the function f(n) represent?

The y intercept :

Value of F(n) when n = 0

F(n) = 12(1 +0.04)^n

F(n) = 12(1 +0.04)^0

Fn = 12(1)

Hence, intercept = 12

Answer:

1. 7/41

2. 7/15

Step-by-step explanation:

1. Probability that it is a multiple of 6 given that it is a 2 digit number: There are 7 numbers that are a multiple of 6 and are 2 digits: 12, 18, 24, 30, 36, 42, and 48. There are 41 numbers that are 2 digits. So, it is 7/41

2. Probability that it is at least 20 given that it is prime. Out of the prime numbers from 1-50, 7 of them are at least 20 and there are 15 primes in that range in total. So, it is 7/15

Answer:

The answer Is C

Answer:

The measure of <TRU is 72 deg.

Step-by-step explanation:

<QRU is a right angle, so it measures 90 deg.

Since m<QRT = 18 deg, then m<TRU must be 72 deg since 72 + 18 = 90.

Answer: The measure of <TRU is 72 deg.
