Help Please!!!!!!!!!A. (1, -2)B. (1, 2)C. (2, -1)D. Infinite Number Of Solutions

Answers

Answer 1

Answer:

(1, -2)  Option A in your list of possible answers

See attached image.

Step-by-step explanation:

We need to graph the lines by using a couple of points on the plane for each equation.

For example:

the points (0, -3)  and (3, 0) for the line  y = x - 3

and the points (0, 1) and (-1, 4) for the line  y = - 3 x + 1

Please see the lines in the attached image, and notice that they intersect at the point (1, -2), which gives you the solution for the system.

Answers

Answer: ? = 6

Step-by-step explanation:

3 divided by 1/x = 18

3x= 18

x = 6

Answer:

3 divided by 1 equals 3

How :

We can write 3 divided by 1 as a ratio, fraction, or equation. Let's try writing this statement in all these ways

3:1

3/1

3÷1

The easiest way for me to solve this question is as a fraction so let's solve it like that. If the denominator is a 1, we immediately know that the answer is the numerator and that you don't need the denominator. so we can take away the 1 from 3/1 and that is how our answer is 3!

Hope this Helps!!! :)

Let me know in the comments if the answer was perfect or if I should change anything!!! :)

Reduce the Fraction: a(x-2y)/b(2y-x)

Answers

Answer:

[tex]\displaystyle-\frac{a}{b}[/tex]

Step-by-step explanation:

We have:

[tex]\displaystyle{\frac{a(x-2y)}{b(2y-x)}[/tex]

In the denominator, we can factor out a negative 1. This yields:

[tex]=\displaystyle\frac{a(x-2y)}{-b(x-2y)}[/tex]

We can now cancel out the factor. Hence:

[tex]\displaystyle=-\frac{a}{b}[/tex]

Answer:

Option A: 11,1 is the correct answer.

Step-by-step explanation:

The absolute value is used in the given expressions.

The absolute value represents the values of a number or variable irrespective of its sign. This means that |x| = x and |-x| = 0

Given expression is:

[tex]|2x-5|[/tex]

Putting x=3

[tex]|2(-3)-5| \\= |-6-5|\\= |-11|\\=11[/tex]

Putting x=-3

[tex]|2(3)-5| \\= |6-5|\\= |1|\\=1[/tex]

Hence,

Option A: 11,1 is the correct answer.

Step-by-step explanation:

The right side is a ratio [tex]0.84:\frac{7}{15}[/tex] a ratio can be written as a fraction [tex]\frac{0.84}{\frac{7}{15} }[/tex] this means [tex]0.84[/tex] divide by [tex]\frac{7}{15}[/tex] which is the same as [tex]0.84*\frac{15}{7}=\frac{12.6}{7}[/tex] On the left, change the mixed fraction [tex]3\frac{1}{3}[/tex] to the improper fraction [tex]\frac{10}{3}[/tex] Then divide [tex]0.3d-1[/tex] by [tex]\frac{10}{3}[/tex] which is same as [tex](0.3d-1)*\frac{3}{10} =\frac{3(0.3d-1)}{10}[/tex] So the equation is now [tex]\frac{3(0.3d-1)}{10}=\frac{12.6}{7}[/tex] Now multiply both sides by 10 and 7:[tex](10)*(7)*\frac{3(0.3d-1)}{10}=\frac{12.6}{7}*(7)*(10)\\7*3(0.3d-1)=12.6*(10)\\21*(0.3d-1)=126\\6.3d-21=126\\6.3d-21+(21)=126+(21)\\6.3d=147\\d=\frac{147}{6.3}[/tex]
