Answer:

5 family members went swimming with the dolphins.

Step-by-step explanation:

From the information given, you can say that the total cost for the family to swim with dolphins is equal to the flat fee for the family to rent wet suits plus the extra cost per person for the number of family members:

1024.99=75+189.99x, where x is the number of family members

Now, you can solve for x:

1024.99-75=189.99x

949.99=189.99x

x=949.99/189.99

x=5

According to this, the answer is that 5 family members went swimming with the dolphins.

Answer:

B. 55

Step-by-step explanation:

The angle measurements on the top are the same as the bottom, so we know  the angle next to (x+70) is 55. You then subtract 55 from 180 and you are left with 125. Then you have to subtract 70 to find x, which gives you 55. Therefore, x=55

Answer:

0.25

Step-by-step explanation:

The fraction is 18/72. The decimal is different. If you divide 72 by 18, you get 4. That tells you how it is in a quarter, aka four pieces. Divide 100 by 4, you get 25. That’s why the  answer is 0.25

Step-by-step explanation:

See attachment

Answer: 9 months

Step-by-step explanation:

It's a pattern of multiplying by 2.

4 x 2 = 8

8 x 2 = 16

16 x 2 = 32

32 x 2 = 64

64 x 2 = 128

128 x 2 = 256

256 x 2 = 512

512 x 2 = 1,024

Answer:

1 and 3 = 84

Step-by-step explanation:

the lines are parelle meaning you will get the same agles

we know that all the even angles are equal to 96 degrees

we need to do 180- 96= 84

so know we know that 84 equalls all the odd numbers

Answer:

1) The coordinates of P' is (7, -5)

2) The coordinates of P' is (-5, -7)

3) The coordinates of P' is (-7, 5)

4) The coordinates of A' is (7, 5);

5) Q' is (-7, 5)

6) The coordinates of L is (-6, 7)

7) The coordinates of A''' is (1, 10)

Step-by-step explanation:

1) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)

Therefore, given that the preimage P is (5, 7), we have the image, P', after 90 degrees clockwise rotation is (7, -5);

2) The coordinates of a preimage (x, y) after 180-degrees clockwise rotation gives the image (-x, -y)

Given that the preimage, point P, has coordinates (5, 7) the image, P', after 180-degrees rotation becomes (-5, -7)

3) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)

∴ The coordinates of the preimage, P = (5, 7), after 270-degrees clockwise rotation gives the image, P', = (-7, 5)

4) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)

Therefore, given that the preimage A is (-5, 7), we have the image, A', after 90 degrees clockwise rotation is (7, 5);

5) The coordinate of the preimage, point Q is (5, 7) after 270-degrees clockwise rotation gives the image, Q', = (-7, 5)

6) The image of a preimage, (x, y) after 180-degrees rotation is (-x, -y). Therefore, given that the image of the preimage L, after 180 degrees rotation is L' (6, -7), we have the coordinates of L is (-6, 7)

7) The coordinates of the preimage, A = (-5, -8)

a) A is translated 6 units to the right and 2 units to give;

A'(-5 + 6, -8 - 2) = A'*1, -10)

b) (x, y) is reflected across the line y = -x, to give (-y, -x)

∴ A'(1, -10) is reflected across the line y = -x, A''(10, -1)

c) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)

∴ The coordinates of the preimage, A''(10, -1), after 270-degrees clockwise rotation gives the image, A'''(1, 10).

Step-by-step explanation:

for example:

4 * 5 = 20

other ways of writing multiply:

4 x 5 = 20

 4(5) = 20

Answer:

Usually in math it is used to indicate multiplication.

Step-by-step explanation:

Most of the time people will use * instead of x for multiplication on a calculator or computer.

Hope this helps. Plz give brainliest.

Answer:

-2

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( 3-9)/(0- -3)

   = (3-9)/(0+3)

  = -6/3

  = -2

Answer:

why can u do this yourself ?

Step-by-step explanation:

are u ok r ur hands broken

Explanation:

4x+3y=37

y=x-4

4x+3(x-4)=37

4x+3x-12=37

add 12 to both sides

7x=49

x=7

Now you use plug in x

4(7)+3y=37

28+3y=37

subtract 28 to both sides

3y=9

y=3

answer: x=7 and y=3

Answer:

The difference quotient of f is 8. Option C

Explanation:

Difference Quotient

Given a function f(x), the difference quotient is defined as

[tex]\displaystyle d=\frac{f(h+h)-f(x)}{h},\ h\neq 0[/tex]

The function provided in the question is

[tex]f(x)=8x+1[/tex]

Find f(x+h) by substituting x by x+h:

[tex]f(x+h)=8(x+h)+1[/tex]

[tex]f(x+h)=8x+8h+1[/tex]

Now compute:

[tex]\displaystyle d=\frac{8x+8h+1-(8x+1)}{h}[/tex]

Operating:

[tex]\displaystyle d=\frac{8x+8h+1-8x-1}{h}[/tex]

Simplifying:

[tex]\displaystyle d=\frac{8h}{h}[/tex]

d=8

A.  Incorrect.

This choice is different from the answer.

B. Incorrect.

This choice is different from the answer.

C. Is correct

The difference quotient is 8 as explained above.

D. Incorrect.

This choice is different from the answer.

Answer:

the answer would be B: 4x=3y

Step-by-step explanation:

this is perimeter which means that you add the side lengths all together.

5x-3y+x+4y-2x+2y

then you just add the like terms

Answer:

b) 4x + 3y

Step-by-step explanation:

add all equations (perimeter = side + side + side)

P= 5x-3y + x+4y -2x+2y

combine like terms

5x + x - 2x = 4x and -3y + 4y + 2y = 3y

P = 4x + 3y

Answer:

see explanation

Step-by-step explanation:

The general expansion of (a + b)² is

(a + b)² = a² + 2ab + b²

Applying this to the following expansions

(1)

(x + 2)² = x² + 2(2x) + 2² = x² + 4x + 4 ← missing term is x²

(2)

(2x - 3)² = (2x)² + 2(2x)(- 3) + 3² = 4x² - 12x +9 ← missing term is - 12x

(3)

(3x + 4)² = (3x)² + 2(3x)(4) + 4² = 9x² + 24x + 16 ← missing term is 16

(4)

(x - y)² = x² + 2(x)(- y) + y² = x² - 2xy + y² ← missing term is x²

(5)

(2x + 3y)² = (2x)² + 2(2x)(3y) + (3y)² = 4x² + 12xy + 9y² ← missing term is + 12xy
