Please help me with the question below

Answer:

[tex]x_{1} =-\frac{9}{2} \\x_{2} = \frac{9}{2}[/tex]

Step-by-step explanation:

[tex]4x^2 = 76 + 5\\4x^2 = 81\\x^2 = \frac{81}{4}\\ x = |\frac{9}{2}|[/tex]

Answer:

X = 9/2

Step-by-step explanation:

4x² - 5 = 76

4x² = 76 + 5

4x² = 81

4x² = 9²

(2x)² = 9²

2x = 9

X = 9/2

Answer:

(0,0) (2,4) (-2,-4)

Step-by-step explanation:

The expression for the statement given can be written as 2 + 6n. The correct option is (B).  

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

Suppose the required number be n.

Then, the expression for the statement can be written as follows,

Add 2 to the product of n and 6 to obtain,

2 + 6n

Hence, the required expression is given as 2 + 6n.

Answer:

$.03 per second

Step-by-step explanation:

Take the debt and divide by  the number of years

4 , 253 , 335 /5

850667 per day

The divide by how many days in a year

850667/365

2330.594521 per day

Then divide by 24 hours in a day

2330.594521 /24

97.10810502 per hour

Then divide by 60 minutes in an hour

97.10810502/60

1.618468417 per minute

The divide by 60 seconds  in an hour

1.618468417/60

.026974474 per second

$.03 per second

Answer: Option D.

Step-by-step explanation:

Out of the 15 simulations, the number with a 1 in them is 7. (are the sets of 5 shots that have at least one 3-pointer)

So out of 15 sets, 7 of them have at least one 3-point in them.

the experimental probability is p = 7/15.

So the correct option is D.

Answer:

There are 320 mL in 2 cans

Step-by-step explanation:

Since one can holds 160 mL of orange juice, all we need to do is add them together since it is to cans to get 320 mL.

Answer:

There are 320 mL in 2 cans

Step-by-step explanation:

Since one can holds 160 mL of orange juice, all we need to do is add them together since it is to cans to get 320 mL.

i originally said 320ml but my answer was deleted.

Answer:

D) 4

Step-by-step explanation:

To start with we can see that on all the line there are little arrows on the end which means that the line continues forever.

C and B are acute angle because we can eyeball that they are less then 90 degrees.

A is most likely to be a right angle because their are two perpendicular straight lines.

D is the correct answer because as I said the lines continue forever. So in that case both lines are not perpendicular or less than 90º.

Answer:

98 centimeters

Step-by-step explanation:

perimeter of rectangle=2(l+b)

width=breadth=77centimetrs

perimeter=340 centimeters

340=2(l+77)

340=2l+144

340-144=2l

196=2l

l=98 centimetrs

Answer:

1.) Chances of picking a black marble: 28/81 or 34.6%

2). 0/81 chances of picking a purple marble or 0%

3.) Chances of picking a red or white marble: 35/81 or 43.2%

4.) Chances of picking a marble whose color has 5 letter in it: 40/81 or 49.4%

Answer:

A. x-axis

Step-by-step explanation:

The answer is the x-axis because the trangle is an exact reflection flipped across the x-axis. We also know this was flipped across the x-axis because the x values do not change, but the y values are the exact opposite. For example, point M has coordinates (1,-1) while point M' has coordinates (1,1). This is the same for points K, K', J, and J'.

Answer:

180

Step-by-step explanation:

for 40 to be equal to 80 in percentages, the number has to be duplicated

Answer:

180

Step-by-step explanation:

90×80/100=72

40/100×x=72

transpose 100

40x=72×100

x=7200/40=180

Answer:

r = 2 (answer C)

Step-by-step explanation:

Given:  (p - q)/2 = 3, so (p - q) = 6

Next, rp - rq = 12 can be rewritten as r(p - q) = 12, or r(6) = 12

Then r must be 2: r = 2 (answer C)

Answer:

(5,6)

Step-by-step explanation:

I think you are asking whats the biggest sum you can get out of the ordered pairs. If you are I'm pretty sure (5,6) is correct. If you are not asking that, I am sorry.

The closest lower value would be 10.

10^2 = 100

So the two consecutive numbers would be 10 and 11

Answer:

(4, - 4 )

Step-by-step explanation:

Since the dilatation is centred at the origin, multiply the original coordinates by the scale factor, that is

(1, - 1 ) → (4(1), 4(- 1)) → (4, - 4 )

The value of X is -3.

Good luck on your assignment

Answer:

[tex]x = - 3[/tex]

Step-by-step explanation:

[tex] - 8(x + 6) - 1 = 5(x - 2) \\ - 8x - 48 - 1 = 5x - 10 \\ - 8x - 5x = 48 + 1 - 10 \\ - 13x = 39 \\ \frac{ - 13x}{ - 13} = \frac{39}{ - 13} \\ x = - 3[/tex]

Answer:

Look at the attachment

Step-by-step explanation:

Actually, it isn't that hard. Remember the difference of squares? (a + b)(a - b) = a² - b² and in this case 9 is a and 4x is b so our answer is 81 - 16x².

Answer:

9 - 16x²

Step-by-step explanation:

(3+4x)(3-4x)= 3²- (4x)²= 9 - 16x²

Answer:

A)You will earn $20311.62 as interest  if you deposit $23750 into an investment account for 8 years.

B) The annual interest rate to you charge Vinny in order to make the same amount of interest on his loan as your investment account is 10.69%

Step-by-step explanation:

We are given that Your cousin Vinny wants to borrow $23750. He’s willing to pay you back over 8 years with simple interest.

Your alternative is to invest in the $23750 into an account paying 7.75% compounded monthly.

a)How much interest would you earn in your investment if you deposit $23750 into an investment account for 8 years?

Principal = 23750

Rate of interest = 7.75%

No. of compounds per year = 12

Time = 8 years

Formula : [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where A is the amount

P is the principal

r = rate of interest

n = No. of compounds

t = time

Substitute the value sin the formula :

[tex]A=23750(1+\frac{7.75}{1200})^{12 \times 8}[/tex]

A=44061.6163406

Interest = Amount - Principal

Interest = 44061.6163406-23750

Interest =20311.62

You will earn $20311.62 as interest  if you deposit $23750 into an investment account for 8 years.

B)What annual interest rate to you charge Vinny in order to make the same amount of interest on his loan as your investment account

Principal = 23750

Simple interest =[tex]\frac{P \times T \times R}{100}[/tex]

[tex]20311.62=\frac{23750 \times 8 \times R}{100}\\\frac{20311.62 \times 100}{23750 \times 8}=R\\10.69\%=R[/tex]

Hence The annual interest rate to you charge Vinny in order to make the same amount of interest on his loan as your investment account is 10.69%

Answer:

51 = A

Step-by-step explanation:

Using the law of sines

sin 95        sin A

------------- = -----------

9                  7

Using cross products

7 sin 95 = 9 sin A

Divide each side by 9

7/9 sin 95 = sin A

Take the inverse sin of each side

sin ^-1 ( 7/9 sin 95) = A

50.78854367= A

To the nearest degree

51 = A
