Answer:

times 3

Step-by-step explanation:

So this is like integers because it is negative numbers and positive numbers when it is positive and odd numbers that means you could use a number line because numberlines have positive and negative numbers.

Answer:

Range: {1, 3, 11}

Step-by-step explanation:

To find the range, just substitute the inputs into the function to find the outputs.

f(-2) = 2(-2) + 5

f(-2) = -4 + 5

f(-2) = 1

f(-1) = 2(-1) + 5

f(-1) = -2 + 5

f(-1) = 3

f(3) = 2(3) + 5

f(3) = 6 + 5

f(3) = 11

So the range is: {1, 3, 11}.

The coordinates of the image triangle will be:

Please also check the attached figure.

The green triangle represents the image triangle.

Step-by-step explanation:

We know that when we reflect a point across the y-axis, the y-coordinate remains the same but the x-coordinate reveres its sign.

Thus,

The rule of reflection of the point P(x, y) across the y-axis is:

P(x, y) → P'(-x, y)

In the attached figure, let the coordinates of the triangle are:

Using the rule of reflection across the y-axis:

P(x, y) → P'(-x, y)

Thus, the coordinates of the image triangle will be:

A(1, 1) → A'(-1, 1)

B(1, 3) → B'(-1, 3)

C(3, 3) → C'(-3, 3)

Therefore, the coordinates of the image triangle will be:

Please also check the attached figure.

The green triangle represents the image triangle.

Inequalities are used to represent unequal expressions.

The inequality is:

⇒ H ≤ 46

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

The height (h) is said to be no greater than 46 inches.

Here, The text "no greater than" means less than or equal to.

Hence, the inequality is:

⇒ H ≤ 46

Thus, The correct inequality is:

⇒ H ≤ 46

The area of the first figure is 629.86 sq. meters and for the second figure, the combined area would be 430.18 629.86 sq. meters.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

For the first figure, we need to find the area of the semicircles and the area of the rectangle, then we get the combined area that gives the area of the figure.

The length of the rectangle is 28m. we can see that the diameter of the semicircle is equal to half of the length of the rectangle.

So. D = 14m and radius = 7m

The area of the 2 semicircles = [tex]\pi r^2[/tex]

                                              = π x 7 x 7

                                             = 49π sq. meter

The breadth of the rectangle = 24 - r

                                                 = 24 - 7

                                                 = 17m

The area of the rectangle = length × Width

                                           = 28 x 17

                                           = 476 sq. meter

The combined area = 629.86 sq. meter

B. The area of the 2 semicircles = [tex]\pi R^2[/tex] + [tex]\pi r^2[/tex]

                                                      = π ( 11 x 11 + 4 x 4)

                                                      = 3.14 x (121 + 16)

                                                      = 430.18 sq. meter

Under a rotation of

about the origin

a point (x ,y) → (-x ,-y)

hence (-3 ,4) → (3 ,-4)

The point (-3,-5) after a rotation of 180° counterclockwise about the origin changes to  (3, 5).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We also know that when a point P(x, y) is rotated 180° about the origin it changes to ( -x, - y).

Given, Point (-3,-5) after a rotation of 180° counterclockwise about the origin.

∴ The new coordinates of the points are (3, 5).

Answer:

y = 42°

Step-by-step explanation:

The third vertex in the triangle with y is adjacent to a right angle, thus is right.

The sum of the 3 angles in a triangle = 180°, then

y = 180° - (90 + 48)° = 180° - 138° = 42°

[tex]\huge\boxed{\tt{SSS}}[/tex]

Step-by-step explanation:

SSS (Side-Side-Side) Postulate can be used to prove the two triangles congruent.

Here's why:

Whole figure is a parallelogram which means that opposite sides are parallel and equal (or congruent).

So, Two of the sides can be proved congruent by that way.

The third side is common in both of the triangles which means that the third side is also congruent.

Hence, the two triangles are congruent by SSS postulate.

8-7 C and H are not polygon, the rest are all polygon

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

Area is the space occupied by a two dimensional object,

The area and perimeter of the given shape can be determined by dividing it into basic shapes.

here, we have,

The area and the perimeter of the shape given

= Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom

Area of rectangle = 5 mi * 9 mi = 45 sq.mi

Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi

Area of small Triangle = (1/2) * 3*6 = 9 sq.mi

Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi

Area of the figure = 45 +13.5 -9-4.5

Area of the figure =  45 sq.mi

Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom

Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486

Perimeter = 23.5354 mi

Therefore , The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.

Not Linear

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be  0  or  1  for each of its variables. In this case, the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.

Ok.....Since I can't graph it, we can make a table

x       y

3       9

1        1

From 9 to 1, you subtract 8 (this is for the y section)

From 3 to 1, you subtract 2 (this is for the x section)

Now all you have to do is divide the y with the x

y/x = 8/2 = 4

Answer:

She will save [tex]\$24.44[/tex] by driving.

Step-by-step explanation:

Given: Jocelyn lives in Granite Falls. She wants to visit Megan in Spokane Valley. She can fly from Seattle to Spokane for [tex]\$96.20[/tex] round trip or she can drive a total of [tex]650[/tex] miles round trip. If her car gets [tex]25[/tex] miles per gallon, and gas costs [tex]\$2.76[/tex]/gallon.

To find: how much money will she save by driving?

Solution:

The total cost for flying Seattle to Spokane is [tex]\$96.20[/tex].

Now, in order to find how much money will she save by driving, we need to first find the total cost for driving a total of [tex]650[/tex] miles round trip.

So, total distance [tex]=650[/tex] miles.

Car covers [tex]25[/tex] miles per gallon.

So, to cover [tex]650[/tex] miles, [tex]\frac{650}{25} =26[/tex] gallons of gas is required.

Now, gas costs [tex]\$2.76[/tex]/gallon.

Therefore, total charge [tex]=26\times2.76=\$71.76[/tex].

So, total money saved[tex]=\$96.20-\$71.76=\$24.44[/tex]

Hence, she will save [tex]\$24.44[/tex] by driving.
