5 6 7 8. One times a number equals 4 1

Let the first end point be x1 y1 and the second x2 y2 the midpoint would be

x1 + x2 / 2 y1 + y2 / 2

Hence

(19 + x2)/2 = 4

19 + x2 = 8

x2 = 8 -19

x2 = -11

(-10 + y2)/2 =8

- 10 + y2 = 8

y2 = 8 + 10

= 18

The other end point is (-11, 18)

Remember that

1 ft=12 in

1 yd =36 in

so

The garden is 23 ft by 31 ft

Convert to inches

23 ft=23*12=276 in

31 ft=31*12=372 in

Find out the volume

V=(276)*(372)*(4)

V=410,688 in3

Convert to cubic yards

410,688 in3=410,688*(1/36)^3=8.80 cubic yards

Remember that

Answer:

Explanation:

Here, we want to get the values in the segments

a) Here we would have to open up the brackets

Now, to do this, we are going to use the distributive property

By using the distributive property, we will be able to open up the brackets

Doing this, we can get the values in the brackets

So the answer here is distributive property

b) Here, we have

14 = -y after combining the like terms

The correct answer here is the subtraction property of equality

We simply subtract 3y from both sides of the equation to arrive at this answer

c) -14 = y

We have the multiplication property of equality

The reason for this is that we multiplied both sides by -1 to arrive at this answer

d) y = -14

This is the symmetric property of equality

We have this here because if two values are equal on both sides, we can switch each to the opposite sides and still retain the same equality values

Step-by-step explanation:

if x = 2, then x^2 = 4, the inverse would thus be: if x^2 = 4, then x = 2.

This is partially true though since multiple values would satisfy the equation x^2 = 4, or rather 2 values. negative two and positive two. So x=2 is one solution, but just because x^2 = 4, that doesn't necessarily imply that x=2.

Let's take them one after the other

To calculate the mean:

Mean = 4 +20+ 5 +10+ 21+ 18 +10+ 11+ 16 / 9

Mean= 115/9= 12.7

To calculate the median;

Median: position (n+1)/2=(9+1)/2=5

This implies it is the fiifth value after ordering them from least to gratest

Step-by-step explanation:

Mr. Smith paid $935 in sales tax

In order to find the values of f(0), f(1) and f(2), we just need to find in the graph for the value of the function (that is, the value of y) for the values of x equal to 0, 1 and 2 respectively.

Looking at the graph, for x = 0 we have y = -7, therefore f(0) = -7

For x = 1 we have y = -2, therefore f(1) = -2

For x = 2 we have y = -5, therefore f(2) = -5

By the midpoint formula, the real number - 5 / 12 is between the rational numbers - 1 / 3 and - 1 / 2.

Rational numbers are real numbers of the form m / n, where m and n are integers and n is non-zero. There are more than one choice between the rational numbers - 1 / 3 and - 1 / 2, one option can be found by obtaining the midpoint between the two numbers:

x = (1 / 2) · (- 1 / 3) + (1 / 2) · (- 1 / 2)                                   Given

x = - 1 / 6 - 1 / 4                                                                 Multiplication of rational numbers

x = - 4 / 24 - 6 / 24                                                           Modulative, commutative and associative properties / Existence of multiplicative inverse

x = - 10 / 24                                                                       Addition of fraction with same denominator

x = - 5 / 12                                                                         Simplification / Result

The real number - 5 / 12 is between the rational numbers - 1 / 3 and - 1 / 2.

We are given the following inequality

Let us first convert the inequality into slope-intercept form

Comparing this inequality with the standard slope-intercept form we see that

Slope = -3 and y-intercept = 4

So the graph of the inequality is

The area left to the red line represents the solution of the inequality.

Now we need to check if the point (1, 1) lies left to the red line.

We can clearly see that point (1, 1) is just left to the red line hence it is a solution.

Therefore, it is true.

Jane has saved 75% of the radio cost

The linear function to represent the number of mulch delivered to a site  is y = 29x + 35

In mathematics, the term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.

For this question, we can represent the cost of having x cubic yards of mulch delivered to a site. For a standard linear function, it can be represented as y = mx + c

m = slope

c = intercept

We can use this concept to write a linear function to represent this problem:

y = mx + c

y = 29x + 35

In this case, the slope is 29 and the intercept is 35. The slope in this situation is the cost of the mulch and the amount charged by the business is the intercept.

The equation representing this problem is y = 29x + 35

The per pound cost of the bag of oranges which price is $9 for 8-pounds is less .

In the question ,

it is given that a grocery store sells bags of oranges in two different sizes .

in first bag where 3 pound bags of oranges cost $4 .

So, 1 pound bag of orange will cost = 4/3 = $1.333   .

in the second bag where 8 pounds bags of oranges cost $9 .

So, 1 pound bag of orange will cost 9/8 = $1.125   .

we can see that $1.125 < $1.333 .

In this case, Cai is right.

Basically, Cai is right because a ratio is a fraction. So, if you divide the numerator and denomirator by the same number, the fraction won't be changed, in that case you would get an equivalent fraction.

For example, if we have 4/6, and we divide both numbers by 2, we get 2/3, these operations are valid because you are dividing both numbers by the same (2).

We have the sequence: 40, 20, 10, 5,...

Each term is half the previous term, so it is a geometrical sequence with common ratio r = 0.5.

We can not complete the sequence, as it becomes infinitely smaller and does not have a last term.

But we can write the three next terms to complete the blank spaces: 2.5, 1.25, 0.625.

We can start by writing the recursive formula. We know that each term is half the value of the previous term, so we wil have:

From this recursive formula, we can deduce the explicit formula (in terms of n) as:

Answer:

a) Geometric sequence with r = 0.5.

The sequence first terms are: 40, 20, 10, 5, 2.5, 1.25, 0.625.
