Find the quadratic function.

Answer:

120 pounds

Step-by-step explanation:

15 boxes = 45 pounds

45/15= 3

1 box= 3 pounds

40 x 3 = 120

40 boxes would weigh 120 pounds

hope this helps :)

Answer: 120 lbs.

Explanation: One box weighs 3 pounds (divide 45 by 15). 3 times 40 equals 120. So the total weight is 120 pounds.

Answer:

1:6 or 1/6

Step-by-step explanation:

Because the question asks for the goats to the total number of animals, you have to write the ratio in the same order. So, there are 4 goats, and to find the total number of animals, you just add every number.

5+11+4+4=24

The result would be 4:24, and because you need the ratio in the simplest form, you just divide both sides by the same greatest number. Both 4 and 24 can be divided evenly by 4. So, when you simplify, the answer comes out as 1:6. (Ratios can also be written as fractions, just so you know!! For example, the ratio 1:6 can be written as 1/6; both answers would be correct.)

Hope this helps!!!! Have an amazing day :3

Answer:

x = −7

Step-by-step explanation:

2x + 3 = x − 4

Subtract 3 from both sides of the equation

2x = x −7

Subtract x from both sides of the equation

x = −7

Answer:

X=7

Step-by-step explanation:

Step 1  

Having all the  

x

terms on one side of =

Subtract  

2 x

from both sides

2 x − 2 x + 3 = 3 x − 2 x − 4

0 + 3 = x − 4

Swap round

x − 4 = 3

Step 2  

Have just  

x

on the left of =

Add  

4

to both sides

x − 4 + 4 = 3 + 4

x = 7

Answer:

5 cm/s

Step-by-step explanation:

The rate of change (ROC) is the speed at which the y variable (hieght) increases with the x variable (time). so ROC = 5.

the linear equation is y = mx + b, m is also the roc, b is the initial value, so,

if y = 60, x = 4 & b = 40, then making m the subject of equation will give the value of the ROC. i.e m = (y - b)/x = (60 - 40)/4.

Answer:

One solution, as there is only one intersection between these two lines.

x = 2, and y = 1 (point of interesection (2, 1) )

y = 2x-3

y = -x + 3

first step is to substitute the y of one equation into the other and solve for x.

- x + 3 = 2x - 3

___________

+x. +x

_____________

3 = 3x-3

_____________

+3 +3

____________

6 = 3x

_____________

÷3 ÷3

_______________

2 = x

______________

x = 2

_______________

We can verify this value is true by substituting it back into the equations and as a result also solving for the working y value.

x = 2 -> y = 2(x) - 3

2(2) - 3 = 4 - 3 = 1

y = 1

____________

x = 2 -> y = -(x) + 3

-(2) + 3 = -2 + 3 = 1

y = 1

Answer:

The mean age of the frequency distribution for the ages of the residents of a town is 43 years.

Step-by-step explanation:

We are given with the following frequency distribution below;

    Age                      Frequency (f)               X                    

    0 - 9                            30                         4.5                   135

   10 - 19                           32                        14.5                  464

   20 - 29                         12                         24.5                 294

   30 - 39                         20                        34.5                 690

   40 - 49                         25                        44.5                1112.5

   50 - 59                         53                        54.5                2888.5

   60 - 69                         49                        64.5                3160.5

   70 - 79                          13                         74.5                968.5

   80 - 89                          8                          84.5                676        

   Total                            242                                              10389      

Now, the mean of the frequency distribution is given by the following formula;

                         Mean =  

                                    =    = 42.9 ≈ 43 approx.

Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years

Hope this helps

plz mark brainliest

The midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).

A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.

The midpoint is calculated by using the formula:- ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2.

Given points are R(-3,3) and S(1,6). The midpoint of the given points are calculated as below:-

M = (-3+1 ) / 2 , ( 3 + 9 ) / 2

M = ( -1,4.5)

Therefore, the midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).
