Answer:

(-4 - (-2))/(2 - (-2)) = -2/4 = -1/2

Step-by-step explanation:

Pick either point.

y - (-4) = (-1/2)(x - 2)

y + 4 = (-1/2)x + 1

y = (-1/2)x - 3

Answer:

Triangle = 34

A = ½ (b × h)

Parallelogram = 63

A = b × h

Trapezoid = 24

A= (a+b)/2 x h

The one with the greatest area is Parallelogram (63)

Answer:

We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

Step-by-step explanation:

Existence of an inverse function:

An inverse function will exist if: f(a) = f(b) only if a = b.

In this question:

[tex]f(a) = -\frac{1}{7}\sqrt{16 - a^2}[/tex]

[tex]f(b) = -\frac{1}{7}\sqrt{16 - b^2}[/tex]

[tex]-\frac{1}{7}\sqrt{16 - a^2} =-\frac{1}{7}\sqrt{16 - b^2}[/tex]

[tex]\sqrt{16 - a^2} = \sqrt{16 - b^2}[/tex]

[tex](\sqrt{16 - a^2})^2 = (\sqrt{16 - b^2})^2[/tex]

[tex]16 - a^2 = 16 - b^2[/tex]

[tex]a^2 = b^2[/tex]

[tex]a = \pm b[/tex]

We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

Answer:

4 schools

Step-by-step explanation:

Based on the box plot you have given above, the answer would be 20% of the total schools participated for 6 years or more. This is because the part of the box plot wherein it hits 6 years and above is 20%. Thus, if there are 20 schools, then the 20% of it would be 4. In conclusion, there are 4 schools that participated for 6 years or more.

Volume can be measured by counting the number of unit cubic in a

three-dimensional​ figure.

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Volume is the three- dimensional property, its basic units is always in cube.

Volume generally told us how much capacity can handle which we express it with the help of cubic units.

Volume doesn't wok on two dimensional bodies as well as the square is used for finding the area of the figure.

Thus, Volume can be measured by counting the number of unit cubic in a

three-dimensional​ figure.

Answer:

c. 45.34ft

Step-by-step explanation:

When leg one of the triangle is 15ft and leg two is 17 ft you would take   17^2 + 15^2 and then you find the square root of that (514) to get the hypotenuse of the triangle. After that you multiply by two to account for the 2/2 sqaure foot per each unit

Answer:

21 AED

Step-by-step explanation:

W know the cost of each kind of meat

Chicken = 4 AED

Beef = 3 AED

We also know how much of each we will be buying

Chicken = 3.6 kg

Beef = 2.2 kg

Multiply each price of meat by its respective weight, then add the products together for you final answer.

4(3.6) + 3(2.2) = 21

Step-by-step explanation:

When dividing by a fraction flip it over and multiply

2 / (1/3) = 6/1

2 / (1/3) = 6

Answer:

6 and 8

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

Given this,

(3x)² + (4x)² = 10²

9x² + 16x² = 100

25x² = 100

Divide both sides by 25

x² = 4

x = 2

Substitute this into 3x and 4x.

3x = 3 * 2 = 6

4x = 4 * 2 = 8

Thus, the answer is 6 and 8

The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.

Given that, the rhombus is CDEF and the slope of FC is 5/2.

Here, sides FC and CD are perpendicular.

The slope of a line perpendicular to given line is m₁=-1/m₂

Slope of CD is -2/5.

Therefore, option B is the correct answer.

Answer:

Cost of each hoodies = $25.5

Cost of each t-shirt = $12.75

Step-by-step explanation:

Given:

Cost of 2 t-shirt and 2 hoodies = $76.50

Cost of 5 t-shirt and 3 hoodies = $140.25

Find:

Cost of each t-shirt

Computation:

Assume;

Cost of each t-shirt = t

Cost of each hoodies = h

So,

2t + 2h = 76.50..........eq1

5t + 3h = 140.25..........eq2

Eq 1 x 2.5

5t + 5h = 191.25.............eq3

Eq3 - Eq2

2h = 51

h = 25.5

Cost of each hoodies = $25.5

2t + 2h = 76.50

2t + 2(25.5) = 76.50

t = 12.75

Cost of each t-shirt = $12.75
