1. 56 n − 35

2. − 40 p + 13

3. − 77 k − 40

Step-by-step explanation:

The distance travelled by John in 13 hours is 819 miles.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The total distance covered in 8 hours is 504 miles.

Then in one hour, distance covered is given as below,

⇒ Number of miles ÷ Number of hours

⇒ 504 ÷ 8 = 63

Then, the distance covered in 13 hours is given as,

⇒ Unit distance in 1 hour × Number of hours

⇒ 63 × 13 = 819

Hence, the miles travelled in 1 hour is given as 819 miles.

Answer:

x = 94/k

Step-by-step explanation:

kx-4=90

Add 4 to each side

kx-4+4=90+4

kx = 94

Divide each side by k

kx/k = 94/k

x = 94/k

Answer:

W = kq1q2 / r

Step-by-step explanation:

W varies jointly as the product of q1 and q2 and inversely as radius r

Product of q1 and q2 = q1q2

W = (k*q1"q2) / r

W = kq1q2 / r

Where,

W = work

q1 = particle 1

q2 = particle 2

r = radius

k = constant of proportionality

The answer is W = kq1q2 / r

Using proportions, it is found that the formula is:

[tex]W = k\frac{q_1q_2}{r}[/tex]

Then, the formula is:

[tex]W = k\frac{q_1q_2}{r}[/tex]

Answer:

3.

Step-by-step explanation:

3x + 4y = 4..........1

2x + y = 1.............2           Multiply this by 4:

8x + 4y = 4     Subtract this from equation 1:

-5x = 0

x = 0.

So substituting in equation 2:

2(0) + y = 1

y = 1.

Therefore 2x + 3y = 2(0) + 3(1) = 3.

Answer:

[tex]c=\frac{82}{3}-\frac{4}{3}d[/tex]

Step-by-step explanation:

1) Set up an equation

Let c be the number of CDs Nakisa bought.

Let d be the number of DVDs Nakisa bought.

[tex]328=12c+16d[/tex]

Explanation: Each CD costs $12 and each DVD costs $16. Nakisa spent $328 altogether, which means $12c+$16d is equal to $328.

The question is asking for the number of CDs that Nakisa bought, so our goal is to isolate c in the equation above.

2) Isolate c

[tex]328=12c+16d[/tex]

Subtract both sides by 16d

[tex]328-16d=12c+16d-16d\\328-16d=12c[/tex]

Divide both sides by 12

[tex]\frac{328-16d}{12}=\frac{12c}{12} \\\frac{82}{3}-\frac{4}{3}d=c[/tex]

[tex]c=\frac{82}{3}-\frac{4}{3}d[/tex]

Answer:

The correct option is;

Triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime 1 comma negative 1, B prime negative 1 comma 1, and C prime negative 1 comma negative 3

Step-by-step explanation:

The given parameters are;

The equation of the line t over which ΔABC is reflected is given by y = x

The coordinates of the vertices of ΔABC are given as follows;

A(-1, 1), B(1, -1), and C(-3, -1)

The reflection of a preimage (x, y) across the line y = x gives an image with coordinates at (y,  x)

Therefore, the coordinates of the vertices of the image ΔA'B'C' after the reflection of the preimage ΔABC over the line, y = x are given as follows;

Coordinates of preimage → Reflection across y = x → Coordinates of image

A(-1, 1) [tex]{}[/tex]                       Reflection across the line y = x          A'(1, -1)

B(1, -1) [tex]{}[/tex]                       Reflection across the line y = x          B'(-1, 1)

C(-3, -1) [tex]{}[/tex]                     Reflection across the line y = x          C'(-1, -3)

Therefore, the correct option is triangle A prime B prime C prime graphed on a coordinate plane with vertices at A prime 1 comma negative 1, B prime negative 1 comma 1, and C prime negative 1 comma negative 3.

Answer:

9

Step-by-step explanation:

divide -6 by 2 then square the answer(-3)=9

The solution of x² - 6x – 34 = 0 by completing square method is

⇒x   = 3 ±√43

The given quadratic equation is

x² - 6x – 34 = 0,

We know that whole square formula

(p+q)² = p² + q² + 2pq

Now convert the given expression into this form

So adding 9 both sides

⇒  x² - 6x – 34 + 9 = 9

⇒         x² - 6x  + 9 = 43

⇒  x² - (2)(3)x  + 3² = 43

⇒                (x - 3)²  = 43

Taking square root both sides we get

⇒                (x - 3)   = ±√43

Add 3 both sides we get

⇒                       x   = 3 ±√43

Thus the solution of the given quadratic equation is

x   = 3 ±√43
