The possible graph for two points have the same y-coordinate but opposite x-coordinates is shown below.

In a general point (x,y) , the value x represents the distance from origin to point along x - axis,

and

the value y represents the distance from origin to point along y axis.

It is given in the question that

There are two points in which the y coordinate of both the points is same

the x coordinate is of opposite signs.

Let us take an Example  

let the points be A(a,b) and B(c,d)

According to the question

b = d and -a = c

So the points will become (a,b) and (-a,b)

For Example ;

let a=2, b=3

the two points will become (2,3) and (-2,3).

Therefore , the possible graph of these points is shown below .

Answer:

Step-by-step explanation:

n^2 - 18. n=8

Simply plug 8 in place of n. The ^ sign refers to the power of the number, so in this case we square it. Review order of operations if needed.

8^2 - 18

(8×8) - 18

64 - 18 = 46

So the answer is 46

The expression is simplified to x - 147

Algebraic expressions are defined expressions made up of terms, factors, variables, constants , coefficients.

They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.

Given the expressions;

−3 (5x + 1) + 16(x − 9)

First, we have to expand the bracket

-15x -3 + 16x - 144

collect like terms, we have;

-15x + 16x - 144 - 3

Add or subtract like terms as seen in the expression

x - 147

Note that the expression is simplified to x - 147

Thus, the expression is simplified to x - 147

m<2 = 71° [vertical angles theorem]

m<5 = 109°

m<3 = 109°

m<6 = 29°

The alternate interior angles theorem states that two interior angles that are formed along a transversal and lie alternate to each other on two parallel lines are congruent to each other.

Measure of angle 7 = 47° [based on the alternate interior angles theorem]

Measure of angle 8 = 180 - 47 - 71 [triangle sum theorem]

Measure of angle 8 = 62°

Measure of angle 1 = measure of angle 8 = 62° [based on the alternate interior angles theorem]

Measure of angle 1 = 62°

Measure of angle 2 = 71° [vertical angles theorem]

Measure of angle 5 = 180 - 71 [linear angle theorem]

Measure of angle 5 = 109°

Measure of angle 3 = measure of angle 5 = 109° [vertical angles theorem]

Measure of angle 4 = 180 - measure of angle 3 - 36 [linear angle theorem]

Measure of angle 4 = 180 - 109 - 36

Measure of angle 4 = 35°

The minimum and maximum numbers of hours the truck driver will drive before stoping for a rest will be 3.6 hours and 2.4 hours respectively.

From the information, the truck driver is driving on an interstate and is about 150 miles from his planned exit and he is traveling at a speed of 50 miles per hour and plans to stop for a rest within 30 miles of the exit on either side.

Therefore, the appropriate equation be:

50h - 150 = 30

50h = 30 + 150

50h = 180

Divide

h = 180 / 50

h = 3.6 hours.

The minimum hours will be:

50h = 150 - 30

50h = 120

h = 120/50

The two numbers are 6 and 8.

The first step is to determine the simultaneous equations that would be used to determine the answer. The simultaneous equations would be derived from the information provided in the question.

x + y = 14 equation 1

x - y = 2 equation 2

Where:

x = larger number

y = smaller number

The simultaneous equations would be solved using the elimination method

Now, subtract  equation 2 from  equation 1

2y = 12

Divide both sides of the equation by 2

y = 12 / 2

y = 6

Substitute for y in  equation 2

x - 6 = 2

Add 6 to both sides of the  equation

x = 2 + 6

x = 8

The relation is not a function if its domain is on the x-axis and its range is on the y-axis. However, if the relation's domain is on the y-axis and its range is on the x-axis, it is a function.

If so, what kind of function is it?

Relationships are defined by three factors:

1. domain is a set of inputs.

2. an output set referred to as range.

3 . relationships between domain and range-related items.

If and only if each element of the domain is associated to just one member of the range, is a relation a function. It must be noted that the solution may vary based on the domain and range that we assume.

The provided relation is a function if the x-axis is the range and the y-axis is the domain, as opposed to when the x-axis is the domain and the y-axis is the range.

Answer: -3b + 21

Step-by-step explanation:

-3(b-7) distribute the -3 to the rest of the equation

= -3b + 21

Answer:

Step-by-step explanation:

So we have our equation -3(b-7)

We are multiplying -3 by b, and by 7, and subtracting the products from each other

so, -3x7=-21

and we would have -3b

so now, we can put this back into the equation as

-3b+21 (because the rule is that subtracting a negative from a negative is the same as adding a positive)

Hope this helps!^^

Answer:

h = 3V /b

Step-by-step explanation:

V=1/3bh

Solve for h

Multiply each side by 3

3V = 3*1/3bh

3V = bh

Divide each side by b

3V/b = bh/b

3V /b = h

h = 3V /b

Answer:

[tex]3v = bh \\ bh = 3v \\ h = \frac{3v}{b} [/tex]

Answer: $0.65

Step-by-step explanation:

She can have all nickels since at least 3 nickels means that there is a possibility that all 13 of her coins are nickels.

100 cents=1 dollar

Nickel=5 cents

5 cents * 1 dollar/100 cents=

5*1/100=0.05 dollars

Hence, the least total amount of money she could have is:

13*0.05=$0.65

This is equivalent to 140 cents.

==========================================================

Explanation:

"she has at least three each of quarters, dimes, and nickels"

Let's say she has exactly 3 of each for now

So far she has 75+30+15 = 120 cents (aka $1.20) with the 3*3 = 9 coins mentioned. There are 13-9 = 4 coins remaining

To achieve the least money possible, those missing four coins must be the smallest denomination allowed, i.e. the nickel. We can't go for penny since it states "none of them are pennies". So we add 4*5 = 20 more cents onto 120 to get 120+20 = 140 cents aka $1.40
