A. Yes

Just Did It On Khan Academy

Step-by-step explanation:

To get equation A from equation B multiply/divide only one side by a non-zero constant option (C) Multiply/divide only one side by a non-zero constant is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

It is given that:

Two linear equations:

A.   3(x + 2) = 18

B.    x + 2 = 18

In equation B multiply by 3 on one side:

3(x + 2) = 18

Thus, to get equation A from equation B multiply/divide only one side by a non-zero constant option (C) Multiply/divide only one side by a non-zero constant is correct.

Answer:

Perpendicular

Step-by-step explanation:

For this problem, it is important to note two things.  One line is completely vertical, and the other line is completely horizontal.

The line y=9 is completely horizontal at the y-value at 9.  The line x = 2 is completely vertical at the x-value at 2.

Hence, these two lines would be perpendicular.

Cheers.

Answer:

Perpendicular.

Step-by-step explanation:

Since it makes a huge cross +, which we want it to be, we need the lines to intercept and it makes a right angle. That means it is perpendicular.

Answer:

(47-14) h ÷ 3 =11

Step-by-step explanation:

47-14=33

33 divided by 3 is 11

Jackson takes 11 hours to sell 47 cups.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the number of hours that Jackson sold his cups on Sunday.

Now,

Saturday cups + Sunday cups = Total cups.

14 + 3x = 47

3x = 33

x = 11

Hence "Jackson takes 11 hours to sell 47 cups".

You shouldn't need a calculator for this. The quadratic equation is written in standard form.

ax^2 + bx + c = 0

You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.

This is the same as [tex]\frac{n}{4} - 2[/tex] and it is also equivalent to [tex]0.25n-2[/tex]

Explanation:

n is some placeholder for a number

one fourth of that number is [tex]\frac{1}{4}n[/tex] which is the same as [tex]\frac{n}{4}[/tex] or [tex]0.25n[/tex] since 1/4 = 0.25

Answer:

the answer is -30

Step-by-step explanation:

2xy=2*5*-3

= -30

The value of the expression 2xy will be -30.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given expression is 2xy and x = 5 y = -3. To calculate the value put the value of x and y in the expression.

2xy=2 x 5 x -3

2xy= - 30

Therefore, the value of the expression 2xy will be -30.

k/3=11-13

k/3=-2

k=-2*3

Answer:

Number 2 is - 6

Step-by-step explanation:

2. 13 + k/3 = 11

We can start off my subtracting 13 in both sides.

-13 + 13 + k/3 = 11 - 13

k/3 = -2. now we have to multiply 3 in both sides

3 x k/3 = -2 x 3

k = -6

Hi there!

~

Let's solve your equation step-by-step.

[tex]6(m+2)+6m=-5(-7m-7)[/tex]

Step 1: Simplify both sides of the equation.

[tex]6(m+2)+6m=-5(-7m-7)[/tex]

[tex](6)^{(m)} + (6)(2)+6m= (-5)(-7m)+(-5)(-7)[/tex] (Distribute)

[tex]6m+12+6m=35m+35[/tex]

[tex](6m + 6m)+(12)=35m + 35[/tex] (Combine Like Terms)

[tex]12m + 12 = 35m + 35[/tex]

[tex]12m + 12 = 35m + 35[/tex]

Step 2: Subtract 35m from both sides.

[tex]12m + 12 - 35m = 35m + 35 - 35m[/tex]

[tex]-23m + 12 = 35[/tex]

Step 3: Subtract 12 from both sides.

[tex]-23m + 12 - 12= 35 - 12[/tex]

[tex]-23m = 23[/tex]

Step 4: Divide both sides by -23.

[tex]\frac{-23m}{-23} = \frac{23}{-23}[/tex]

[tex]m = 1[/tex]
