Answer:

(2, 5 )

Step-by-step explanation:

3x + 2y = 16 → (1)

2x + y = 9 ( subtract 2x from both sides )

y = 9 - 2x → (2)

substitute y = 9 - 2x into (1)

3x + 2(9 - 2x) =16

3x + 18 - 4x = 16

- x + 18 = 16 ( subtract 18 from both sides )

- x = - 2 ( multiply both sides by - 1 )

x = 2

substitute x = 2 into (2)

y = 9 - 2(2) = 9 - 4 = 5

solution is (2, 5 )

The answer is 1400, good luck

Answer:

n = ±0.13363

Step-by-step explanation:

2/8 - (14*n*(n))=0                                              • Use this formula for proof

2/8 = 1/4                                                            A^2 - AB + BA - B^2 =

1/4 - 14n^2 = 0                                                   A^2 - AB + AB - B^2 =

14n^2 = 14n^2 ÷ 1 = 14n^2 • 4 ÷ 4                      A^2 - B^2

1 - (14n^2 • 4) ÷ 4 = 1 - 56n^2 ÷ 4

1 - 56n^2 ÷ 4 = 0

1-56n2 ÷ 4 • 4 = 0 • 4

1-56n^2  = 0

56n^2 = 1

n^2 = 1/56 = 0.018

n ≈ ±0.13363

Answer:

$1346.4

Step-by-step explanation:

First find the rectangle portions area with lxwxh, which is 8x6x8. That equalls 384.

Then find the triangles, which is bxh, which is 6x8. That equals 144.

Add those two to get 528.

Then multiply the total area by 2.55 which will get you 1346.4

Answer:

$48

Step-by-step explanation:

The number of dollars more is the price of 8 bottles of Brand B than the price of 8 bottles of Brand A oil is:

                       $   48

Step-by-step explanation:

Brand A--

Number of bottles (x)       Price (dollars) y

2                                                   22

3                                                   33

4                                                   44

5                                                   55

The function that represents the relation between the price of the bottles and the number of bottles is:

              y=11x

Brand B--

Also, the price of the bottles depending on the number of bottles is:

                Y=17x  

According to Brand A the price of 8 bottles is:   y=11×8=$ 88

and according to Brand B the price of 8 bottles is: y=17×8= $ 136

Also, the difference in the price of Brand B to that of Brand A for 8 bottles is:

      $ 136-$ 88

   = $ 48

In order to find the answer, we need to multiply 15 x 12 then find the exponent based on the object shape (2D/3D).

15 x 12 = 180.

If the object is 2D, the exponent is 2 (squared). If the object is 3D, the exponent is 3 (cubed). We can tell that the object is 2D, so the exponent is 2.

The answer is 180^2, or 180 squared.

I was hoping that you'd give me Brainiest as I'm trying to rank up. If you want to, please do!

Answer:

The answer is 180 squared.

Answer:

Ok so, pizza one is 17 inches in diameter, which in order to find area of a circle/circumferences, you first need to divide by 2, in this case 17/2=8.5, then square it, 8.5*8.5=72.25, then multiply by PI (3.14 in this case.) 72.25*3.14=226.865 which can round up to 227. Or 226.9

Step-by-step explanation:

Divide by 2

Square

Multiply by pi. (3.14)

Observe that

y = x² - 2kx = x (x - 2k)

has roots at x = 0 and x = 2k. Since the leading coefficient is 1 > 0, the parabola opens upward, and in particular this means the x-axis lies above the curve.

We can compute the area of R by integrating:

[tex]\displaystyle \int_0^{2k} |x^2-2kx| \, dx = - \int_0^{2k} (x^2-2kx) \, dx \\\\ = kx^2 -\frac{x^3}3 \bigg|_{0}^{2k} \\\\ = \frac{4k^3}3[/tex]

Solve for k :

[tex]\dfrac{4k^3}3 = 36 \implies k^3 = 27 \implies \boxed{k=3} ~~~~ (B)[/tex]

Use the distance formula:

[tex]\sf d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

where (x1, y1), (x2, y1) are points

[tex]\rightarrow \sf d =\sqrt{(5-(-2))^2 + (6-(-4))^2}[/tex]

[tex]\rightarrow \sf d =\sqrt{(7)^2 + (10)^2}[/tex]

[tex]\rightarrow \sf d =\sqrt{149}[/tex]

This is the length of diameter.

Then radius:

Answer:

C. g(x) = (x - 4)²

Explanation

g(x) is f(x) right 4 units

When shifted right, x - a, a is the distance

So g(x) = (x - 4)² is the answer

Answer:

Step-by-step explanation:

friend ,for you to calculate this question you have to know the formula which is 1/2 h (a + b) x height. then use the procedure written in the picture of which you should end up dividing as I have then you will eventually get your answer but the key point is that you should know the formula and the number at the right side is the one dividing the area (37.4) not the area dividing the number at the right side which is 9.35 good day.

Answer:

You can choose classes of amplitude 5 , it may give you a better representation of the data :

Step-by-step explanation:

Since events a and b are independent P(a and b) = P(a) × P(b)

To answer the question, we need to know what probability is

Probability is the likelihood of an event to occur. The probability of the event P(event) = number of required outcomes/total number of outcomes

If we have two independent event sa and b that have probabilities of occuring P(a) and P(b) respectively, the probability P(a and b) = P(a) × P(b)

So, P(a and b) = P(a) × P(b)

Answer: B

Step-by-step explanation:

By the intersecting chords theorem, (3)(5)=4x, meaning x=3.75.

Answer:

Step-by-step explanation:

39-27=12

51-39=12

63-51=12

It’s clear that ,in this sequence we add 12 each time to a term to get the next term.

This means that this is an arithmetic sequence with a common difference of 12.

Therefore,

Term1 = 27  ; Term2 = 39  ; Term3 = 51  ; Term4 = 63

Term5 = 75

Term6 = 87

Term7 = 99

Term8 = 111

Method 2 :

Un = U1 + (n-1)r

r is the common difference = 12

U1 = 27 is the first term

Then

U8 = 27 + (8-1)×12

     = 27 + 7×12

     = 27 + 84

     = 111

[tex]h(-1)[/tex] ⇢ [tex]-h[/tex]

Answer:

1 hour and 30 minutes

[tex]t = ch + td = fh[/tex]

where ch is current hour, td is time distance, and fh is final hour.

to find td, we must subtract the number of minutes in ch and fh and then base how many hours passed off of the minutes.

[tex]cm(45) - fm(15) = 30[/tex]

If half an hour passed, we can guess that only another hour passed, therefore we can make a final equation using eh for "estimated hour".

[tex]t = (cm - fm) + eh = 1:30[/tex]

The expression in the 6th term in the binomial expression is [tex]265781250y^6[/tex]

The expression is given as:

(5y + 3)^10

The above expression is a binomial expression, and the xth term can be represented using:

[tex]^nC_x (a)^x * (b)^{n-x}[/tex]

So, we have:

[tex]^{10}C_6 * (5y)^6 * (3)^4[/tex]

Evaluate the combination expression

[tex]210 * (5y)^6 * (3)^4[/tex]

Evaluate the exponents

[tex]210 * 15625y^6 * 81[/tex]

Evaluate the product

[tex]265781250y^6[/tex]

Hence, the expression in the 6th term is [tex]265781250y^6[/tex]
