Answer:

Step-by-step explanation:

(6.8)m=2

We move all terms to the left:

(6.8)m-(2)=0

We multiply parentheses

6.8m-2=0

We move all terms containing m to the left, all other terms to the right

6.8m=2

m=2/6.8

m=1/3.4

Answer:

  length, width, perimeter

Step-by-step explanation:

First of all, you should notice that no problem is posed. A description is given, but no question is asked about it.

If we assume that the length and width of the patio are desired, then those are the selections for the first two boxes.

The only other characteristic of the situation that is provided is the perimeter. So the formula for perimeter is the only one that can be usefully used.

Answer:

slope is 1

Step-by-step explanation:

when the x-axis is zero the y-axis is the slope

Answer:

y = 2x + 1

Step-by-step explanation:

Slope intercept form is y = mx + b, where m is the slope and b is the y-intercept. When we look at the graph we see that at x = 0 our y-value is 1. This is our y-intercept meaning that b = 1. To find the slope of the line, you divide the difference in the y-values between 2 points on the line by the difference in the x-values between 2 points on the line. Let's choose 2 points! Our 1st point is going to be (0,1) and our second point is (1,3).

[tex]m=\frac{3-1}{1-0}=\frac{2}{1}=2[/tex]

After we have found both our m and b value, we simply plug in these numbers into the slope intercept form.

m = 2

b = 1

y = 2x + 1

Answer:

y - 31 = 7/3(x - 12)

Step-by-step explanation:

Point slope form is: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point

Plug in the slope and the given point:

y - y1 = m(x - x1)

y - 31 = 7/3(x - 12)

So, the point-slope form of the line is y - 31 = 7/3(x - 12)

Answer:

D

Step-by-step explanation:

The coordinates of the image of vertex R after a reflection across the y-axis is (4,-3), the correct option is B.

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure. Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

We are given that;

The vertex R=(-4,-3)

Now,

When reflecting a point across the y-axis, the x-coordinate changes its sign, while the y-coordinate remains the same. Therefore, the image of vertex R(-4,-3) after reflection across the y-axis would be the point (4,-3), since its x-coordinate changes its sign and its y-coordinate stays the same.

Therefore, by reflection the answer will be (4,-3).

answer to problem:

n = 3

Answer:

A. m∠ 2= 41°

B. m∠4 =61°

Step-by-step explanation:

Compliment means that the two angles will add up to 90°, and Supplement means to add up to 180°.

A. m∠1 + m∠2 = 90°

49°+ m∠2 = 90°

m∠2 = 90° - 49°

m∠2 = 41°

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

B. m∠3 + m∠4 = 180°

119 + m∠4 = 180°

m∠4 = 180° - 119°

Answer:

15x + 16

Explanation:

Basically whatever you are solving for in this question, the answer will be the exact same

Split it into two shapes a square and a triangle.

Square =  3 x 3 = 9

Triangle = 1/2 x base x height

The height would be the side of the square = 3

The base would be the length of the top line minus the length of the side of the square = 7-3 = 4

1/2 x 4 x 3 = 6

Total area = 6 + 9 = 15 square units.

Answer:

Step-by-step explanation:

area of a trapezoid = (a + b) * h/2

where a = 3,  b = 7,  h = 3

plugin values into the formula:

A = (3 + 7) * (3/2)

A = 15 sq. units.

Answer:

28 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 7 and h = 8 , thus

A = [tex]\frac{1}{2}[/tex] × 7 × 8 = [tex]\frac{1}{2}[/tex] × 56 = 28 cm²

Answer:

Minimum Values:

x = 0, y = 1, z = 3

Maximum Values:

x = 7 , y = 11 , z = 47

Step-by-step explanation:

FOR MINIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the minimum value of x must be 0.

y>= 1

This inequality shows that the minimum value of y must be 1. Using these minimum values of x and y to get the minimum value of z:

z = 2x + 3y

z = (2)(0) + (3)(1)

z = 3 (Minimum)

FOR MAXIMUM VALUES:

0<= x <= 7

It is clear from the above inequality that the maximum value of x must be 7.

x + y <= 11

To calculate maximum value of y we can use the minimum value of x in this inequality:

0 + y <= 11

y <= 11

Hence, the maximum value of y is 11.

Using these maximum values of x and y to get the maximum value of z:

z = 2x + 3y

z = (2)(7) + (3)(11)

z = 47 (Maximum)

Answer:

-2.6

Step-by-step explanation:

10.9 + (-15.6) becomes 10.9 - 15.6 which equals -4.7. The last step is to add the 2.1 to the -4.7: -4.7 + 2.1 = -2.6

Therefore the answer is -2.6

The value of the expression 10.9 + (-15.6) + 2.1 will be negative 2.6.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The decimal number is the sum of a whole number and part of the fraction number. The fraction number is greater than zero but less than one.

The expression is given below.

⇒ 10.9 + (-15.6) + 2.1

⇒ 10.9 - 15.6 + 2.1

⇒ 13 - 15.6

⇒ - 2.6

The value of the expression 10.9 + (-15.6) + 2.1 will be negative 2.6.

The monthly inflow of Tamara will be $624 after deducting taxes.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.

Given,

Earning of Tamara per hour=$8/hour

1 week = 25 hours of working

Earning of Tamara per week = 8(25) = $200/week

1 Month = 4 pays

Earning of Tamara per month = 200(4) = $800/month

Now,

22% of 800 is

22(800)/100 = $176

Remaining salary(cash inflow)

800 - 176 = $624

Hence, The monthly inflow of Tamara will be $624 after deducting taxes.

Tamara's monthly cash inflow is $624.

We have Tamara who earns $8 an hour at her job working 25 hours per week and 22% of her paycheck goes to taxes.

We have to Tamara’s monthly cash inflow.

Tax is a compulsory contribution to state revenue, levied by the government on workers' income and business profits, or added to the cost of some goods, services, and transactions.

According to the question -

Tamara's pay per hour = $8

Tamara's working hours per week = 25

% cut in taxes = 22%

Assuming 4 pays per month -

Cash inflow = $8 x 25 x 4 = $8 x 100 = $800

Cash deducted in taxes = 22% 0f 800 = [tex]\frac{22}{100} \times 800[/tex] = 22 x 8 = $176

Therefore, her monthly cash inflow = $800 - $176 = $624

Hence, Tamara's monthly cash inflow is $624.
