Write the equation of the line in slope-intercept form

Answer:

66.5cm²

Step-by-step explanation:

Area of trapezium = [tex]\frac{1}{2}[/tex] (sum of parallel sides) × height

Let parallel side 1 = 12cm

parallel side 2 = 7cm

height = 7cm

Area = [tex]\frac{12 + 7}{2}[/tex] × 7 = 66.5cm²

The expression [tex]2- \dfrac{x-1}{x+2}[/tex]  is equivalent to [tex]1 + \dfrac{3}{x+2}[/tex].

We have to find, which equation is equivalent to the given expression.

The given expression is,

[tex]= 2- \dfrac{x-1}{x+2}[/tex]

To determine the equivalent expression following all the steps given below.

                   [tex]\rm = 2-\dfrac{x-1}{x+2}\\\\= \dfrac{2(x+2) - (x-1)}{x+2}\\\\= \dfrac{2x+4-x+1}{x+2}\\\\[/tex]

                    [tex]= \dfrac{2x+4-x+1}{x+2}\\\\= \dfrac{x+5}{x+2}\\\\[/tex]

                    [tex]=\dfrac{x+5}{x+2}\\\\= \dfrac{x+ 2+3}{x+2}\\\\[/tex]

                    [tex]= \dfrac{x+2}{x+2} + \dfrac{3}{x+2}\\\\= 1 + \dfrac{3}{x+2}[/tex]

Hence, The expression [tex]2- \dfrac{x-1}{x+2}[/tex]  is equivalent to [tex]1 + \dfrac{3}{x+2}[/tex].

Answer:

[tex]x=10[/tex]

Step-by-step explanation:

For all right triangles, the Pythagorean Theorem states:

[tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse, or the longest side, of the right triangle.

Therefore, we have (starting from the blanks):

[tex]x^2+576=676,\\x^2+576-676=676-676,\\x^2=100,\\x=\boxed{10}[/tex]

The magnitude of rotational symmetry of the regular octagon below the marked point is 45°, so option A is correct.

Eight sides, eight internal angles, and eight vertices are the characteristics of an octagon. An octagon is referred to as being regular if all of its sides and angles have the same measurements.

Given:

From the figure, the lengths of the side of the octagon are equal,

So the angle will also be equal,

And we know that octagon has 8 interior angles and their sum is 360 degrees.

Now for measure of one angle = 360° / 8 = 45°,

Therefore, the magnitude of rotational symmetry of the regular octagon below the marked point is 45°.

Answer:

ED = 6

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{ED}{BA}[/tex] = [tex]\frac{EF}{BC}[/tex] , substitute values

[tex]\frac{ED}{9}[/tex] = [tex]\frac{12}{18}[/tex] ( cross- multiply )

Answer:

WX = 38

Step-by-step explanation:

To get this, we are gong to use the cosine rule

We have the general form as;

a^2 = b^2 + c^2 - 2bc Cos A

Let WX be a

a^2 = 17^2 + 26^2 -2(17)(26) cos 123

a^2 = 1446.46

a = √1446.46

a = 38.03

Answer:

Because 1/9 is a fraction with integers meaning it is a fraction with whole numbers.

Step-by-step explanation:

Any number that can be written as a fraction with integers is called a rational number. For example, 17 and −34 are rational numbers. (Note that there is more than one way to write the same rational number as a ratio of integers. For example, 17 and 214 represent the same rational number.)

Answer:

1048.05 square feet.

Step-by-step explanation:

The area of the deck is 50.4 x 22 = 1108.8 square ft.

The area of 1 cut out is 4.5 x 4.5 = 20.25

There are 3 cut outs so total area of the cut outs is 20.25 x 3 = 60.75 square ft.

The total area of the boards is : 1108.8 - 60.75 = 1048.05 square feet.

Answer:

The ? represents the number 38 because the average rate of change on every interval of the function is 3

Step-by-step explanation:

Firstly, we calculate the average rate of change over a function can be calculated using the formula below;

f(b) -f(a)/(b-a)

Now, over the interval [-2,2]

we have;

(17-5)/(2/(-2)) = 12/4 = 3

This is expected to be the blanket average rate of change

Thus, we have it that over the interval [5,9]; we have;

3 = f(b) - 26/9-5

3 = f(b) - 26/4

4(3) = f(b) - 26

12 = f(b) - 26

f(b) = 12 + 26

f(b) = 38

Answer:

The fraction that would represent the part of Pedro's spins that were blue would be [tex]\frac{7}{10}[/tex].

Step-by-step explanation:

In a fraction, there is a numerator and a denominator. In order to get a fraction that would represent the part of Pedro's spins that were blue, you need to put the number of times the pointer landed on blue as a numerator and the total number of spins as the denominator. Therefore a fraction that would represent the part of Pedro's spins that were blue would be [tex]\frac{7}{10}[/tex].

Answer:

Surface area of the figure = 1672 [tex]cm^{2}[/tex]

Step-by-step explanation:

Surface area of the figure = surface area of the prism + surface area of the 3 cubes

The surface area of the rectangular prism = sum of the area of its individual sides

                                             = 2(26 x 10) + 2(10 x 10) + 2(26 x 10)

                                             = 520 + 200 + 520

The surface area of the rectangular prism = 1240 [tex]cm^{2}[/tex]

Surface area of one of the cubes = 5(6 x 6)

                                                      = 180 [tex]cm^{2}[/tex]

The surface area of the 3 cubes = 3 x 180

                                                     = 540 [tex]cm^{2}[/tex]

Thus, the surfaces of the cubes on the prism covers a total area of 108 [tex]cm^{2}[/tex].

So that;

The surface area of the figure = (1240 - 108) + 540

                                               = 1132 + 540

                                                = 1672 [tex]cm^{2}[/tex]

Answer:

3 < x < 11

Step-by-step explanation:

triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the third side

if 'x' is the third side then:

x + 4 > 7

7 + 4 > x

therefore,  'x' must be greater than 3 and less than 11

The value of the third side should be < 11 so, it cannot be 11, the correct option is C.

A triangle is a polygon with three sides, three vertices and three angles.

The two sides of a triangle are  4 and 7

According to the property of sides of a triangle, The measure of the third side of a triangle is always less than the sum of the two sides.

The sum of the sides is 4+7 = 11

Let the third side be x

then,

x < 11

The x cannot be 11.

B. 7

C. 11

Answer:

(a) If r is any rational number and s is any irrational number, then r/s is rational

(b) The statement is false when r is 0

Step-by-step explanation:

Given

[tex]r \to[/tex] rational number

[tex]s \to[/tex] irrational number

[tex]\frac{r}{s} \to[/tex] irrational number

Solving (a): The negation

To get the negation of a statement, we only need to negate the end result

In other words, the number type of r and s will remain the same, but r/s will be negated.

So, the negation is:

[tex]r \to[/tex] rational number

[tex]s \to[/tex] irrational number

[tex]\frac{r}{s} \to[/tex] rational number

Solving (b): When r/s is irrational is false

Given that:

[tex]\frac{r}{s} \to[/tex] irrational number

Set r to 0

So:

[tex]\frac{r}{s} = \frac{0}{s}[/tex]

[tex]\frac{r}{s} = 0[/tex] -- rational

Hence, the statement is false when r is 0
