Step-by-step explanation:

f(x) = 12 / ( 4x+2)

Let x = -1

f(-1) = 12 / ( 4*-1+2)

Erin drinks the same amount of milk every day. The equation below represents the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk. 16m=2d How long does it take for Erin to drink 1 gallon of milk?

Answers

Answer:

8 days

Step-by-step explanation:

We have that the proportional relationship between the number of gallons of milk (m) and the numbers of days (d) Erin drinks milk is:

[tex] 16m = 2d [/tex]

Hence, the days that would take Erin to drink 1 gallon of milk is:                      

[tex] d = \frac{16m}{2} = 8m = 8*1 = 8 d [/tex]

Therefore, it would take for Erin 8 days to drink 1 gallon of milk.

Answers

Answer:

27

Step-by-step explanation:

Given that:

Green shirt = 81 students

White shirt = 54 students

Orange shirt = 27 students

The largest number of student in each row : we need to obtain the greatest common factor for the three numbers.

Factors of :

81 : 1, 3, 9, 27, 81

54 : 1, 2, 3, 6, 9, 18, 27, 54

27: 1, 3, 9, 27

The greatest factor which is common in all three numbers is 27, hence, the largest number of student in each row should be 27

Jon caught four fish that weighed a total of 264 pounds. The kingfish weighed twice as much as the
amberjack and the white marlin weighed twice as much as the kingfish. The weight of the tarpon was 5
times the weight of the amberjack.
How much did each fish weigh?

Answers

Answer:

Amber jack 22 pounds

Tarpon 110 pounds

King fish = 44 pounds

White Marlin = 88 pounds

Step-by-step explanation:

Let the weight of the amber jack be x pounds

Kingfish weighed twice as much = 2 * x = 2x pounds

White Marlin weighed 2 times kingfish

= 2x * 2 = 4x pounds

Tarpon weighs 5 times amber jack = 5 * x = 5x

Add all together to give 264

5x + 4x + 2x + x = 264

12x = 264

x = 264/12

x = 22 pounds

Hence ;

Amberjack weighs 22 pounds

Tarpon = 5 * 22 = 110 pounds

Kingfish = 2 * 22 = 44 pounds

White Marlin = 2 times king fish = 2 * 44 = 88 pounds

a) (-1,-)
b) (-:-)
c) (-1,-)
d) (-3,-)

Answers

Answer:

I think it's B

...........

Answer:

d

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (1, [tex]\frac{1}{2}[/tex] ), thus

midpoint = ( [tex]\frac{-2+1}{2}[/tex], [tex]\frac{-3+\frac{1}{2} }{2}[/tex] ) =  ( [tex]\frac{-1}{2}[/tex], [tex]\frac{-3+\frac{1}{2} }{2}[/tex] ) = ( - [tex]\frac{1}{2}[/tex], [tex]\frac{-\frac{5}{2} }{2}[/tex] ) = ( - [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{4}[/tex] ) → d

What is the distance between two points ( p,q) and (x,y)?

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]    units.

Given that Square ABCD has vertices; A(-4.5, 4), B(3.5, 4),C(3.5, -4), and D(-4.5, -4).

To find the distance from two of the vertices of the square. The distance formula is as follows;

√[(x-p)² + (y-q)²]  

A(-4.5, 4), B(3.5, 4),

D = √[(x-p)² + (y-q)²]  

D = √(3.5-(-4.5))² +(4 -(4))²

D = √(3.5-(-4.5))² +(4 -(4))²

D = √(64 + 0)

D = 8

Therefore, the side of the square is 8 units.

The area of the square = side x side

= 8 x 8

= 64 unit sq.

What is the distance between two points?

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

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

For this problem, the points are A(2,6) and N(5,10), hence the distance is given by:

[tex]D = \sqrt{(5 - 2)^2+(10 - 6)^2}[/tex]

D = sqrt(3² + 4²)

D = sqrt(25)

D = 5.

The distance between the points A(2,6) and N(5,10) is of 5 units.
