Answer:

(3,8): No,  (-1,-11): Yes,  (2,7): Yes,  (0,-6): No

Step-by-step explanation:

Basically, you just substitute x and y with the numbers given.

18x - 3y = 15

y = 6x - 5

(3,8):

18(3) - 3(8) = 15

54 - 24 = 30  It is not equal to 15, so it does not work.

y = 6x - 5

8 = 6(3) - 5

8 = 13  It is not equal to 8, so it does not work.

Therefore, (3,8) is not a solution.

Try this for every pair and you will find that (-1,-11) and (2,7) are solutions.

I hope this helps!

Answer:

1. The formula used to the find distance formula is: [tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

2. The distance between the points (-3,8) and (-4, -2) is 10.04

Step-by-step explanation:

1. Which of the following is the correct form of the distance formula?

The formula used to the find distance formula is: [tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

2. Use the distance formula to find the distance between the points (-3.8) and (-4. -?)

Note: Since the y-term in (-4,-) is missing So, I am using -2 to solve the question and find distance. You can use the term given in question and replace it with -2 and use this solution as reference to solve and find the correct answer.

We have points (-3,8) and (-4,-2)

Putting values in distance formula and finding result:

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

We have x_1=-3, y_1=8, x_2=-4, y_2=-2

[tex]Distance=\sqrt{(-2-(-3))^2+(-2-8)^2}\\Distance=\sqrt{(-2+3)^2+(-2-8)^2}\\Distance=\sqrt{(1)^2+(-10)^2}\\Distance=\sqrt{1+100}\\Distance=\sqrt{101}\\Distance=10.04[/tex]

So, the distance between the points (-3,8) and (-4, -2) is 10.04

Step-by-step explanation:

Hope I helped!

The solution is Option G.

The value of the equation A = ( 2/3 ) x 15% x $ 2000 = $ 200

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 2/3 ) x 15% x 2000   be equation (1)

On simplifying the equation , we get

A = ( 2/3 ) x ( 15/100 ) x 2000

A = ( 2/3 ) x ( 15 ) x ( 20 )

On further simplification , we get

A = ( 2/3 ) x 300

A = 2 x 100

A = $ 200

Therefore , the value of A is $ 200

Hence , the equation is A = $ 200

Answer:

4.5 and 1.5

Step-by-step explanation:

4.5+1.5=6

4.5-1.5=3(difference)

Answer:

4.5 and 1.5

Step-by-step explanation:

Let the 2 numbers be x and y with x > y , then

x + y = 6 → (1)

x - y = 3 → (2)

Add the 2 equations term by term to eliminate y, that is

2x + 0 = 9

2x = 9 ( divide both sides by 2 )

x = 4.5

Substitute x = 4.5 into (1) for value of y

4.5 + y = 6 ( subtract 4.5 from both sides )

y = 1.5

The 2 numbers are 4.5 and 1.5

Given:

cos 120°

To find:

The exact value of cos 120° in simplest form with a rational  denominator.

Solution:

We have,

[tex]\cos 120^\circ[/tex]

It can be written as

[tex]\cos 120^\circ=\cos (90^\circ+30^\circ)[/tex]

[tex]\cos 120^\circ=-\sin 30^\circ[/tex]             [tex][\because \cos (90^\circ-\theta)=-\sin \theta][/tex]

[tex]\cos 120^\circ=-\left(\dfrac{1}{2}\right)[/tex]             [tex][\because \sin 30^\circ=\dfrac{1}{2}][/tex]

[tex]\cos 120^\circ=-\dfrac{1}{2}[/tex]

Therefore, the exact value of cos 120° is [tex]-\dfrac{1}{2}[/tex].

Answer:

From Calculating, the slope would be 0.

Step-by-step explanation:

           This is because of the fact that the two points create a straight line across the x-axis. The points do not have any distance up or down, the only distance is 8 units across. The slope would be 0 because there isn't a slope, only a distance. Hope this helps.

Step-by-step explanation:

Answer:

no the y may be to the degree of 1 but the variables in the equation violate the linear equation definition. Therefore the equation is not linear.

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables.

Answer:

a) The distance travelled on the cycle in the first 14 seconds is 96 meters.

b) The acceleration in the first 4 seconds is 2 meters per square second.

Step-by-step explanation:

a) The distance travelled by the cycle is equal to the area below the curve, which is the sum of the first triangle and the rectangle:

[tex]\Delta x = \frac{1}{2}\cdot \left(8\,\frac{m}{s} \right) \cdot (4\,s-0\,s)+\left(8\,\frac{m}{s}\right)\cdot (14\,s-4\,s)[/tex]

[tex]\Delta x = 16\,m +80\,m[/tex]

[tex]\Delta x = 96\,m[/tex]

The distance travelled on the cycle in the first 14 seconds is 96 meters.

b) The acceleration is represented by the slope of the line, which is determined by definition of secant line:

[tex]a = \frac{v(4\,s)-v(0\,s)}{4\,s-0\,s}[/tex] (1)

[tex]a = \frac{8\,\frac{m}{s}-0\,\frac{m}{s}}{4\,s-0\,s}[/tex]

[tex]a =2\,\frac{m}{s^{2}}[/tex]

The acceleration in the first 4 seconds is 2 meters per square second.

Answer:

5:2

Step-by-step explanation:

Start with what the question is asking for, which is the ratio of math problems to minutes.

With ratios "to" also means ":", so you can change it to math problems : minutes.

Then, substitute the numbers for the labels. Math problems = 10 and minutes = 4, so now you have 10:4

Lastly, to simplify the ratio, find the greatest common factor, in this case 2, and divide both sides, which gives you your answer 5:2

Step-by-step explanation:

Equation Solving

Given the equation

2(x - 4) = 17

Solving for x implies doing several operations needed to have x isolated in the left part of the equation.

Dividing by 2:

x - 4 = 17/2

x - 4 = 8.5

Now we add 4:

x = 8.5 + 4

x = 12.5

Answer:

There are three terms in the expression.

Step-by-step explanation:

Some background knowledge:

Algebraic expressions do not include equal signs.

Terms are generally values that are added or subtracted.

For example,

2x+6 has two terms which are 2x and 6.

Here:

The term 2x has a coefficient (the number next to a variable) of 2 and the term '6' is a constant.

Please note that a constant is a number that does not include a variable.

LET US SOLVE OUR CASE:

Given the expression

15.5 - (6 x 2) - (16 ÷ 4)

Please note that:

Therefore, there are three terms in the expression.
