Describe the 4 cases to look out for when dealing with adding or subtracting integers

Answer:

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:

M = [(x1 + x2)/2, (y1 + y2)/2]

Angle is a point where two straight lines meet.

Answer:

square root of 50 estimated to the nearest integer is, 7.1

Step-by-step explanation:

step 1. the square root of 50 is 7.07106781186548

step 2. reduce is 7.07

step 3. round 7.07 so you only have one digit after the decimal point to get the answer., 7.1

Answer:

7

Step-by-step explanation:

Consider perfect squares either side of 50, that is

49 < 50 < 64, thus

[tex]\sqrt{49}[/tex] < [tex]\sqrt{50}[/tex] < [tex]\sqrt{64}[/tex] , that is

7 < [tex]\sqrt{50}[/tex] < 8

Since 50 is nearer to 49 than it is to 64, then

[tex]\sqrt{50}[/tex] ≈ 7 ( to the nearest integer )

Answer:

Is it y

Step-by-step explanation:

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

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).

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.

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.

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.

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.

Hence , this is the required solution.

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

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%.

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
