Type your solution as an ordered pair.

Answer:

1) 9

2) -3

3) -14

4) -27

5) 40

6) -30

7) -1

8) -81

Each Sum Or Difference:- (1). 9   (2). -3    (3). -14   (4). -27    (5). 40   (6). -30    (7). -1    (8). -81

As we know,

Suppose a and b be two numbers then to find the sum or difference of these two, we can follow some conditions that are given below:

+ or - becomes - and the answer has a sign of greater one from them

+ or + becomes + and answer has +ve sign

- or + becomes - and the answer has a sign of greater one from them

- or - becomes + but the answer has a -ve sign

Then, according to the above conditions the solutions are given below:

1). 12 + (-3) = 9

2). -7 + 4 = -3

3). -8 + (-6) = -14

4). -42 + 15 = -27

5). 32 - (-8) = 32 + 8 = 40

6). -18 - 12 = -30

7). -15 - (-14) = -15 + 14 = -1

8). -76 - 5 = -81

Answer:

28x + 4, 0 < x < 10

22x + 8, x ≥ 10

Step-by-step explanation:

The piece wise function models the cost of x pounds of trout will be 28x + 4, 0 < x < 10 and 22x + 8, x ≥ 10.Option A is correct.

A connection between independent variables and the dependent variable.is defined by the function.

Given data;

Trout costs for each pound are, $28,

Shipping charges,$4

x is the number of orders

Given condition;

Karen orders 10 or more pounds, the trout costs only $22 per pound, but the shipping fee is $8.

Functions help to represent graphs and equations. A function is represented by two variables one is dependent and another one is an independent function.

The total amount is found as;

⇒No of orders × price of trout per pound + shipping charge per order

⇒28x + 4,

For condition 2 the total value is represented as;

⇒No of orders × price of trout per pound + shipping charge per order

⇒ 22x + 8

The piece wise function models the cost of x pounds of trout will be 28x + 4, 0 < x < 10 and  22x + 8, x ≥ 10.

Hence, option A is correct.

Answer: k = 19

because (6k+31)°  is the outer angle of the triangle

=> (6k+31)° = (3k - 12)° + (6k - 14)°

⇔ 6k + 31 = 9k - 26

⇔ 9k - 6k = 31 + 26

⇔ 3k = 57

⇔ k = 57/3 = 19

that is the answer

Answer:

36%

Step-by-step explanation:

"Percent'' or ''%'' means ''out of 100'' or '' per 100'',

Therefore x% can be written as x/100.

So we can write and solve for x;

27/75= x/100

100 X 27/75 = 100 X x/100

2700/75 = 100 X x/100

36=x

27/75= 36/100= 36%

Answer:

x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.

Step-by-step explanation:

Let Lin works x hours per week.

Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.

And she has to work at least 5 hours a week to $175 per week.

So, the inequality that can be written from the above condition is x ≥ 5 .......(1)

And the equation that can be written that  

8.25x + 10 = 175 ....... (2)  

Now, fro equation (2) we can write x = 20 hours which satisfies equation (1).

The inequality of the situation is x ≥ 5, 8.25x + 10 = 175, and x = 20 hours.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Let Lin work x hours per week. Now given that Lin’s job pays $8.25 an hour plus $10 of transportation allowance each week.

And she has to work at least 5 hours a week for $175 per week.

So, the inequality that can be written from the above condition is,

x ≥ 5 .......(1)

And the equation that can be written that  

8.25x + 10 = 175 ....... (2)

What do squares, rectangles, and right triangles have in common? They all contain at least one right angle!

What shape has at least one right angle?

rectangle

A rectangle is a four-sided shape where every angle is a right angle (90°). Also, the opposite sides are parallel and of equal length.

The shapes which contain at least one right angle from the given shapes are the first and third figures.

Given are four shapes.

It is required to find the shape with at least one right angle.

Now, right angles can be defined as the angle whose measure is exactly 90 degrees.

Anything measure of angle which is less than or greater than 90 degrees is not a right angle.

Consider the first figure.

There are 2 right angles marked in squared shape inside the shape in the right part.

So, the first figure contains the right angle.

In the second figure, all angle measures are 108 degrees. So none is a right angle.

In the third figure, all the angles are right angles since all are marked as squares.

In the last figure, the angle measures are only 73° and 107°. So, this is not right angles.

Hence, the options are first and third figures.
