Answer:

22,950

Step-by-step explanation:

subtract 51,550 and 28,600. 0 - 0 = 0 then 5-0=5 5-6 you can not do so you barrow from the 1. 1 becomes 0 and 5 becomes 15. 15-6=9. 0-8 you can not do so you need to borrow from the 5. 5 becomes 4 and 0 becomes 10. 10-8=2. Finally, 4-2=2. Put is all together and you have 22,950.

Step-by-step explanation:

The negative cancels out each other

Answer:

f(-2)=45

Step-by-step explanation:

f(x)=5(x+11)

x= -2

so basicly its just 5(-2+11)

which is -10+55 and that is 45

so f(-2)=45

Considering the given function, it is found that the numeric value at x = -2 is of f(-2) = 45.

The function is defined by:

f(x) = 5(x + 11).

Hence, when x = -2, we have that:

f(-2) = 5(-2 + 11) = 5 x 9 = 45.

Answer:

This has infinite solutions.

Step-by-step explanation:

Key skills needed are: One variable equations, Algebra, Adding/Subtracting Like Terms

1) We first start with the equation: 8 + 2 (x - 6 ) = -2 +2x - 2​

2) We first need to use distribution property for the parentheses.

We need to distribute the 2 to the x and the -6.

3) This would be 8 + 2x - 12 = -2 +2x - 2

4) The next thing to do is combine like terms.

Like terms are terms with the same variable, or no variable at all. 8 and 6 would be like terms, and 2x and 4x would be like terms. 2x^2 and 4x would not be like terms as one has x^2 and the other has only x.

3) Now you know what like terms are, you can implement this into the problem --> Combine the 8 and 12 on the left side  + Combine the -2 and -2 on the right side ----> 2x-4 = 2x-4

4) Since both sides have the same exact thing (both sides have 2x-4) this equation has infinite solutions.

Answer: The answer is A, $78.00

Step-by-step explanation: Hope it helps

The required cost of the item after 4% of sales tax is given as $78.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Let the total cost of the item be x,
According to the question,
x = cost + sales tax
X = 75 + 4% of 75
x = 75 + 3
x = $78

Thus, the required cost of the item after 4% of sales tax is given as $78.

Answer:

Is there a picture for this one and also you didn't mention the slope of the red line is?

Step-by-step explanation:

Answer:

The slope of the Green line should be the same as the red line- but a negative number instead of a positive.

Step-by-step explanation:

This is the inverse of the line

So by reflecting it over the y-axis, the slope remains the same but will change from positive to negative and vise versa

Answer:

equation : 2x + 4 = 3x - 5

X = 9

BC = 22

The equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.

In Euclidean geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles. It can also be defined as a rectangle with two equal-length adjacent sides.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

A mathematical equation is used to equate two expressions.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is square ABCD and AB = 2x + 4 and CD = 3x - 5

Now -

AB = CD

Equation will be -

2x + 4 = 3x - 5

4 + 5 = 3x - 2x

x = 9

and

AB = BC = CD = AD = 2x + 4 = 2 x 9 + 4 = 22

BC = 22

Therefore, the equation will be - (2x + 4 = 3x - 5), x = 9 and BC = 22.

Answer:

x = [tex]\frac{-1}{3}y[/tex] + [tex]\frac{4}{3}[/tex]

Step-by-step explanation:

16 - 12x = 4y

Add -16 to both sides.

-12x + 16 + (-16) = 4y + (-16)

-12x = 4y - 16

Then divide both sides by -12

-12x / (-12) = [tex]\frac{4y-16}{-12}[/tex]

x = [tex]\frac{-1}{3}y[/tex] + [tex]\frac{4}{3}[/tex]

Answer:

the constabt or proportinaity is 2 because

2/1=2

4/2=2

8/4=2

10/5=2

Step-by-step explanation:

Given:

The equation is

[tex]3x+4y=24[/tex]

To find:

The x- and y-intercepts of the given equation.

Solution:

We have,

[tex]3x+4y=24[/tex]

Putting x=0, we get

[tex]3(0)+4y=24[/tex]

[tex]0+4y=24[/tex]

[tex]y=\dfrac{24}{4}[/tex]

[tex]y=6[/tex]

Therefore, the y-intercept of the given equation is 6.

Putting y=0, we get

[tex]3x+4(0)=24[/tex]

[tex]3x+0=24[/tex]

[tex]x=\dfrac{24}{3}[/tex]

[tex]x=8[/tex]

Therefore, the x-intercept of the given equation is 8.

Answer:

x+4+2x = 20+5x-32

Step-by-step explanation:

x+4+2x

= 3x + 4

20+5x-32

= 20-32+5x

= 5x-12

Finding the value of X

3x+4 = 5x-12

= 4+12 = 5x-3x

= 16 = 2x

= 16/2 = X

= 8 = X

By putting the value of X in the equation

(3×8)+4

= 24 +4

= 28

(5×8)-12

= 40-12

28

28 = 28

so the X+4+2x < 20+5x-32 is wrong
