Answer:

D

Step-by-step explanation:

I'll try to be brief

Let's plug in our 'y' variable (2x)

2x + (2x) = 20

4x = 20

x = 5

Now, plug in our 'x' variable to get our 'y' variable:

y = 2(5)

y = 10

So, our answer in (5, 10)

Or, D

(a)

The expression are equivalent to each ohter if both expressions give same value for all assign values of x. From the table it can be observed that both expression do not give same value for all values of x. Thus expression

and 3x + 4 are not eqivalent to each other.

(b)

From the table, it can be observed that values of the expression are equal for x = 4. So equation

holds true for x = 4.

A straight line can be written in the form of a two variable linear equation.

The equation of line passing through point (4,0) is  y = -1 / 17 x + 4.

To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.

Given that,

The line is passing through the point (4,0).

It is parallel to the line passing through (7, -3) and (-10. -2).

The slope of the line passing through (7, -3) and (-10. -2) is

m₁ = (-2-(-3)) / (-10 - 7)

m₁ = - 1 / 17

Since the slope of two lines parallel to each other is equal, the slope of the line passing through point (4,0) is - 1 / 17.

Thus, the equation of line passing through point (4,0) can be written as,

(y - 4) / (x - 0) =  - 1 / 17

=> y = -1 / 17 x + 4

Hence, the equation of the given line is y = -1 / 17 x + 4.

Answer:

Commission - $15,480 | Money the agency made - $86,000

Step-by-step explanation:

4.5% of $344,000 is $15,480

25% of $344,000 is $86,000

Marcus should choose $2400 plus 3% of sales.

His salary is composed of a fixed salary and a variable salary.

Fixed Salary + Variable Salary = Monthly Salary

2400 150 (3% of 5k) = 2350 - minimum salary he'll receive

2400 300 (3% of 10k) = 2700 - maximum salary he'll receive

VS

Fixed Salary + Variable Salary = Monthly Salary

1500 275 (5.5% of 5k) = 1775 - minimum salary he'll receive

1500 550 (5.5% of 10k) = 2,050 - maximum salary he'll receive

As you can see, despite the high percentage of sales offered, it is not a good option because the fixed salary is low as compared to the other option. Even the maximum salary he'll receive under the option of $1500 is way lower than the minimum salary he'll receive under the option of $2400.

Fixed salary means that each employee receives exactly the same pay and fairness as any other employee in the same pay grade. The level is determined by years of experience and position. For example, all analysts are paid exactly the same all directors are paid the same and all executives are paid the same.

Answer:

There would be 88 fluid ounces in 4 prints and 3 cups.

Step-by-step explanation:

So, if 1 print is equal to two cups, and we have 4 prints, that would mean we can multiply 4 x 2, which equals 8 cups. Now that the prints are out of the way, we add the 3 cups still remaining, to get 11 cups. Now, it wants us to find the fluid ounces, which 16 fluid ounces are in 2 cups, so, 11 divided by 2 = 5.5. So, 5.5 x 16 = 88 fluid ounces.

We want to solve the following equation

x² + 16x + 5 = 0

↓

x² + 16x = 5

We want to rewrite the equation so its left side is

(x + a)²

We know that

(x + a)² = x² + 2ax + a²

where a is a number, then, we want that the left side look something like

x² + 2ax + a²

Then we first want to find which must be the number a in this case.

Since 2 · 8 = 16, then the left side is

x² + 16x = x² + 2 · 8x

then, in this case a would be 8

a = 8

We want that the left side of our equation looks like:

x² + 2ax + a²

Since it has the first two terms

x² + 16x = 5

we have to add a² = 8² = 64

We add it both sides of the equation:

x² + 16x + 8² = 5 + 64

x² + 2 · 8x + 8² = 69

Now, we can write it as (x + a)²

x² + 2 · 8x + 8² = 69

↓ since (x + a)² = x² + 2ax + a²

(x + 8)² = 69

In order to solve the equation, we want to "leave x alone" on the left side:

(x + 8)² = 69

↓ squaring root both sides

(x + 8) = ±√69

x + 8 = ±√69

↓ taking 8 to the right side

x = - 8 ±√69

We have two solutions:

x₁ = - 8 -√69

x₂ = - 8 + √69

The required equation for line M will be 4x+72=y as in the form of y=ax+b because line L is perpendicular to line M.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. a formula that expresses the connection between two expressions on either side of a sign. Typically, it has a single variable and an equal sign. A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

Here,

If x-intercept=B and y-intercept=E

Point B=(16,0)

Point E=(0,4)

point A=(-16,4+4)

=(-16,8)

line M is perpendicular to line L,

slope of L=-4/16

=-1/4

slope of M=-1/-1/4=4

The equation of line M will be,

point=(-16,8)

slope=4

y-8=4(x+16)

y-8=4x+64

4x-y+72=0

Line L is perpendicular to line M, so the required equation for line M will be 4x+72=y in the form of y=ax+b.

The equation of the line that is passing through the point (4,−17) and is perpendicular to y=x/7−3 is 7x -y = -30.

The line is passing through the point (4,-17) and is perpendicular to the line y = x/7-3

Now, the slope of the given line y = x/7-3 is,

M = 1/7

If the other line is perpendicular to it and has slope m, then the, we can write,

Mm = -1

So, putting values,

(1/7)m = -1

m = -7

Now, we have the slope m = -7 of the line and the point (4,-17) of the line,

So, the equation of the line will be,

m = [y-(-17)]/[x-4]

-7 = y+17/x-4

7x+47 = y+17

7x -y = -30

So, the equation of line is 7x -y = -30.

Least common denominator is the lowest number to which all the fractions can be expanded, so it is the Least common multiple of all denominators.

Given that,

We have to find the difference of LCD and LCM.

The least common multiple, or LCM, is the smallest common multiple of any two or more numbers. What does "common" mean? In this context, the word "common" refers to something that is shared by two or more people.

The LCD, or least common denominator, is the least common multiple of two or more denominators. In this instance, the denominator, or bottom number, of a fraction contains the common multiple. When arithmetically adding or subtracting fractions, the LCD must be computed. When dividing or multiplying fractions, the LCD is not required.

For example,

Let's check the following fractions:

(1/2,2/3,5/6)

To find the Least common denominator of the fractions we have to find the Least common multiple of the fractions' denominators:

lcd(1/2,2/3,5/6)=lcm(2,3,6)

To calculate the Least common multiple we have to find the lowest number which can be obtained by multiplying those numbers.

This number is 6 because we can multiply 2×3 and 3×2 to get 6.

Therefore, Least common denominator is the lowest number to which all the fractions can be expanded, so it is the Least common multiple of all denominators.

Answer:

4x - y = - 19 and x + 4y = 8

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

8x - 2y = - 5 ( subtract 8 from both sides )

- 2y = - 8x - 5 ( divide through by - 2 )

y = 4x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form

with slope m = 4

• Parallel lines have equal slopes , then

y = 4x + c ← is the partial equation

to find c substitute (- 4, 3 ) into the partial equation

3 = - 16 + c ⇒ c = 3 + 16 = 19

y = 4x + 19 ← equation of parallel line in slope- intercept form

subtract y from both sides

0 = 4x - y + 19 ( subtract 19 from both sides )

- 19 = 4x - y , that is

4x - y = - 19 ← equation in standard form

----------------------------------------------------------------------

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex] , then

y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation

to find c substitute (- 4, 3 ) into the partial equation

3 = 1 + c ⇒ c = 3 - 1 = 2

y = - [tex]\frac{1}{4}[/tex] x + 2 ← equation of perpendicular line in slope- intercept form

multiply through by 4 to clear the fraction

4y = - x + 8 ( add x to both sides )

x + 4y = 8 ← equation in standard form
