Which of the following represents the area of a rectangle whose length is x - 7 and whose width is x + 12?

Answers

Answer 1
Answer :

Length of rectangle = x - 7

Width of rectangle = x + 12

We have to find area of rectangle[tex].[/tex]

_________________________________

[tex]:\implies\sf\:Area=Length\times Width[/tex]

[tex]:\implies\sf\:Area=(x-7)(x+12)[/tex]

[tex]:\implies\sf\:Area=x^2+12x-7x-84[/tex]

Step-by-step explanation:

The distance between to things is how far apart those two things are.

The Distance Formula is

d = √[(x1 - x2)² + (y1 - y2)²]

Midpoint: This is the point that bisects a segment in the middle.

The Midpoint formula is:

A rectangle has an area of 4x2 +19x + 12 and a length of (x + 4). What is the width?

Answers

The answer is (4x + 3) (x + 4)

The width of the rectangle with an area x² = 19x + 12 is (4x + 3).

What are the area and perimeter of a rectangle?

The area of a rectangle is the product of its length and width.

The perimeter of a rectangle is the sum of the lengths of all the sides.

We know the area of a rectangle is (length×widh).

Given, A rectangle has an area of 4x² + 19x + 12 and a length of (x + 4).

∴ width of the rectangle is = (4x² + 19x + 12)/(x + 4).

Or, we know that the product of two linear equations is a quadratic so,

4x² + 19x + 12.

4x² + 16x + 3x + 12.

4x(x + 4) + 3(x + 4).

(x + 4)(4x + 3).

So, the width of the rectangle is (4x + 3).

Which equation does the graph below represent?
y = 1 x
y = 4x
y = _ 1x
y = -4x

Answers

Answer:

Y=-4x

Step-by-step explanation:

Whenever you solve for slope, and the slope is 1, never write 1 in the equation. Write either -x or x. Let's take two coordinates, one which is (0, 0), which is the origin, and (1, -4). To find the slope, we insert the first coordinate and second coordinate values into the equation (Y2-Y1)/(X2-X1). We can insert these coordinates to get (-4 - 0)/(1 - 0), which simplifies to (-4)/1, which further simplifies to -4. Since the Y-intercept is zero, there is no value of B in the equation, which leaves the equation as Y=-4x

Answers

Given :

Two hockey of same mass.

One is travelling at a speed of 2 m/s.

Other is in rest or 0 m/s.

To Find :

The momentum of  this group of objects.

Solution :

Since , no external force is applied , so momentum will remains same :

Momentum of group of objects ,

[tex]M = mv_1^2+mv_2^2\\\\M = 0.25\times 2^2+0.25\times 0\\\\M=1 \ kg \ m/s[/tex]

Therefore , momentum of the system is 1 kg m/s.

what is the absolute value of 2.3

Answers

Answer:  2.3

The absolute value of any positive number is that number itself.

If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.

The absolute value is never negative. It represents distance from that value to 0 on the number line.

So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.

Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.

The required absolute number of 2.3 is also 2.3.

GIven that,
An absolute number of the value 2.3 is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

The absolute number is defined as the outcome of the modulus function is called the absolute number or all natural numbers are examples of absolute numbers.

Here,
For the absolute value,
f(x) = |x|
f(2.3) = |2.3|
(since |x| = x or | -x  | = x )
f( 2.3 ) = 2.3

Thus, the required absolute number of the value 2.3 is 2.3 itself.

What are Complex Number?

Complex Numbers. Complex numbers are those that are expressed as a+ib, where a and b are actual numbers and I is a fictitious number called a "iota."

Complex numbers are numbers that consist of two parts — a real number and an imaginary number.

Given:

Diameter = –10 – 1 i = (- 10, - 1)

6 + 11 i = (6, 11)

Given that we are aware that these are the diameter's endpoints, it follows that the circle's center is the place that lies midway between the endpoints.

Then,

x = (-10 + 6) / 2

  = - 4 / 2

   = -2

y = (- 1 + 11) / 2

   = 10 / 2

   = 5

Hence, the center is located at (- 2, 5).

A store employee creates a display of sleds priced at $40 apiece. The store paid $32 for each sled. What is the mark-up percentage

Answers

Answer:

Mark-up percentage is 25%.

Step-by-step explanation:

From the question, the store bought each sled at $32 which is the cost price. The sled was display for sale at $40 apiece.

Mark-up percentage = [tex]\frac{selling price - cost price}{cost price}[/tex] x 100%

But,

selling price - cost price = $40 - $32

                                        = $8

So that,

Mark-up percentage = [tex]\frac{8}{32}[/tex] x 100%

                                  = 0.25 x 100%

                                  = 25%

Therefore, the mark-up percentage is 25%.

−8y−13=14y+11 what is the answer?

Answers

Answer:

y = -12/11

Step-by-step explanation:

-8y - 13 = 14y + 11

-8y - 14y = 11 + 13

-22y = 24

y = 24/-22

y = -12/11

Check:

-8*-12/11  -  13 = 14*-12/11 + 11

96/11  -  13 = -168/11  +  11

96/11 - 143/11 = -168/11 + 121/11 = -47/11

Jerry bought a coat on sale for 30% off. The sale price for the coat was $63, what is the regular price for the coat?

Answers

Answer:

The original regular price for the coat is $90

Step-by-step explanation:

The given information in the question are;

The percentage that was off (removed) from the sale price = 30%

The sale price at which Jerry bought the coat = $63

Whereby the regular price = P, we have;

P - 30% of P = $63

P - 0.3×P = $63

P×(1 - 0.3) = $63

0.7·P = $63

P = $63/0.7 = $90

Therefore, the regular (original) price for the coat = $90

The coat regular price at which the coat is displayed is at $90.
