We know that

• The width of the rectangle is 3.6 inches.

• The perimeter is 72 inches.

The perimeter formula for a rectangle is

Where P = 72, w = 3.6, and we have to solve for l.

First find the slope of the first line

L1

m = ( y2-y1)/(x2-x1)

m = ( 1-2)/(3-1)

= -1/2

Now find the slope of the second line

L2

m= ( y2-y1)/(x2-x1)

= ( 0 - -1)/(2 -0)

= (0+1)/(2-0)

= 1/2

Parallel lines have the same slope

These lines do not have the same slope, they are different by a negative sign.

These lines are not parallel.

The percentage of completion is 63.34%.

Let

x -----> pounds of one kind of nuts ($2.00 per pound)

y ----> pounds of other kind of nuts ($2.90 per pound)

we have that

2x+2.90y=2.50(16) ------> equation 1

x+y=16-----> x=16-y -----> equation 2

solve the system of equations

substitute equation 2 in equation 1

2(16-y)+2.90y=40

solve for y

32-2y+2.90y=40

2.90y-2y=40-32

0.90y=8

y=8.89

Find out the value of x

x=16-8.89

x=7.11

therefore

the answer is

EXPLANATION

We want to solve for m in the equation:

This means that we want to make m the subject of formula.

That is:

That is the answer.

The given equation is

The slope of the given line is 4/3 because it's the coefficient of x.

Now, the new line has a slope of 4/3 too because parallel lines have equal slopes.

We know that the new line passes through the point (5, -8). Let's use the point-slope formula to find the equation.

Replacing the points and the slope, we have.

Step-by-step explanation:

Angle 7 is congruent to angle 5 by the corresponding angles theorem, and angles 5 and 12 are supplementary because they are consecutive interior angles.

Thus, angles 7 and 12 are supplementary.

Angles are given below.

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus ," which means "corner," is where the term "angle" originates. When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.

Given,

∠6 and ∠7 = Vertical angles

∠2 and ∠8 = Same side exterior angles

∠1 and ∠5 = Corresponding angles

∠3 and ∠6 = Adjacent angles

∠2 and ∠7 = Alternate exterior angles

∠4 and ∠6 = Same side interior angles

∠1 and ∠2 = Linear pair

Answer: gurl you think i know

Step-by-step explanation:

To simplify the expressions you have to combine the like terms.

This means that you'll solve the operations between the terms that have the same variables, for example x + 2x=3x

Or the terms that have no variables and are only numbers, for example 4+5=9

a. The expression is

Both terms have the same variable "x", so you can add them together. To do so, add the coefficients, i.e. the numbers that are being multiplied by x

And you get that the simplified expression is 7x

b. The expression is

In this expression you have two types of terms, the x-related terms and one constant. In this case you have to solve the operation for the x-related terms together and leave the constant as it is

The simplified expression is 8x-1

The value of k is 9 for the function g.

To solve this problem we should have a brief concept of algebraic functions.

To solve this problem we have to follow a few steps.

Here f is a function of x and the relation with the function denotes as x²-2x. Also, g is a function of x and the relation with the function denotes as x− 2.

If we put, x = 2 on  f(x) = x²-2x. We can write, f(2) = 2²-2.2 = 4 - 4 = 0.

If we put, x = 2 on g (x) = x − 2. We can write, g(2) = x− 2= 2- 2 = 0.

Hence, we can conclude that f(2) = g(2) = 0.      ( proved)

Here, g(k) = 7. So, x = k in this relation.

We have to put x= k on g(x) = x− 2 ; now we can write, g (k) = k− 2.

g (k) = k− 2 = 7 as per the question. Therefore k = 7 + 2 = 9

The value of k is 9.

Using the probability concept, the odds of rolling a number greater than 5 is 1 :5

What is probability ?

probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur or how likely it is that a proposition is true . the probability of an event is a number between 0 and 1 , where ,roughly speaking ,0 indicates impossibility of the event and 1 indicates certainty.

The odd of a particular experiment is defined thus :

Number of possible outcomes greater than 5 : number of possible below or equal to 5

Sample space = {1, 2, 3, 4, 5, 6}

Outcomes greater than 5 = {6} = 1

Outcomes below or equal to 5 = {1, 2, 3, 4, 5} = 5

The odds equals to 1 : 5

If Point m represents the opposite of negative 1/2 and point n represents the opposite of positive 5/2. Then M is 1/2 and N is -5/2.

A number system is defined as the representation of numbers by using digits or other symbols in a consistent manner.

A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.

Given that point M represents the opposite of negative 1/2. Which means opposite of -1/2. The opposite of  -1/2 means positive of 1/2. The sign changes.

Point N represents the opposite of positive 5/2. Which means opposite of 5/2. The opposite of  5/2 means negative of 5/2. The sign changes.

opposite of positive 5/2 is -5/2.

Now let us plot this values on a number line. 1/2 is 0.5 and -5/2 means -2.5.

The graph is attached below.

Hence M is 1/2 and N is -5/2

Answer: P can be anything from 8 to below

Example: 8, 7, 6, 5, 4, 3, 2, 1, 0, -1 .....

Let the two numbers be represented with x and y.

Quotient of two numbers = -1:

Difference of two numbers = 8:

From the first equation, make x the the subject.

Thus, we have:

x = -y

Substitute -y for x in equation 2:

-y - y = 8

-2y = 8

Divide both sides by -2:

Now, substitute -4 for y in equation 2:

x - y = 8

x - (-4) = 8

x + 4 = 8

Subtract 4 from both sides:

x + 4 - 4 = 8 - 4

x = 4

Therefore,

x = 4 and y = -4

Thus, the numbers are 4 and -4

ANSWER:

Area of a triangle ABC with the given vertices is 3 square units.

Given that, the vertices of a triangle ABC, A(3,-6), B(5,-6), and C(7,–9).

In Geometry, a triangle is a three-sided polygon that has three edges and three vertices. The area of the triangle is the space covered by the triangle in a two-dimensional plane.

Area of a triangle = [tex]\frac{1}{2} ( |x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)|)[/tex]

Here, (x1, y1) = A(3,-6), (x2, y2) = B(5,-6), and (x3, y3) = C(7,–9)

Now, the area of a triangle = 1/2 (|3(-6+9)+5(-9+6)+7(-6+6)|)

= 1/2 (|3(3)+5(-3)+7(0)|)

= 1/2 (|(9-15)|)

= 1/2 × 6

= 3 square units

Therefore, area of a triangle ABC with the given vertices is 3 square units.

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals. So, since the slope of the given line is 2/3, the slope of the line we want to find is -3/2.

Rearranging equations 1 and 2 into slope intercept form,

[tex]3x+2y=12 \implies 2y=-3x+12 \implies y=-\frac{3}{2}x+6\\\\3x-2y=12 \implies 2y-3x=-12 \implies 2y=3x-12 \implies y=\frac{3}{2}x-6[/tex]

From this, we see that equation 1 is the answer.

Answer

Option B is correct.

Angle Y = 68º

Explanation

Similar triangles have the same set of angles in them.

All the corresponding angles are equal to each other.

So, if triangle ABC is similar to triangle XYZ

Angle A = Angle X

Angle B = Angle Y

Angle C = Angle Z

The order in which they are named determines the angles that are corresponding to each other.

So, if Angle B = 68º

Angle Y = Angle B = 68º
