Answer:

The upper reason is your answer.....

Step-by-step explanation:

1: - 13= 7x + 4 - 4x

Isolate variables.

- 13= 7x + 4 - 4x

-13 = 3x + 4

-3x = 13+4

-3x = 17

x = -17/3

2: - b - 6 + 6b = 27

5b - 6 = 27

5b = 33

b = 33/5

3: - 5(5x - 2) = 65

-25x + 10 = 65

-25x = 55

x = -55/25

x = -11/5

Answer:

2.29 rads

Step-by-step explanation:

The  length of the arc of a circle of radius r is given by;

l = rθ            ---------------------------(i)

Where;

l = length of the arc

θ = central angle o that intercepts that arc and measured in radians.

From the question:

l = 16ft

r = 7ft

Substitute these values into equation (i) as follows;

16 = 7θ

Make θ subject of the formula

θ = [tex]\frac{16}{7}[/tex]

θ = 2.29    

Therefore, the radian measure of the central angle is 2.29 rads

Answer:

65

Step-by-step explanation:

TAB is an isosceles triangle by the point to tangent theorem theorem.

BAT and BAT are congruent because of the isosceles triangle definition.

CAT and ABT are right angles by the tangent theorem.  

Thus, CAB and CBA are both 90 - 65 = 25.

ACB is 130 because triangles' angles add up to 180.

APB is one half of ACB by the inscribed angles theorem.

The measure of the arc APB will be 230°. Then the correct option is D.

What is a circle?

It is the circle of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

We know that the tangents are equal.

Then triangle ΔATB is an isosceles triangle.

Then the angle ∠TAB and angle ∠TBA are congruent.

We know that the angle sum of a triangle is 180°.

∠TAB + ∠TBA + ∠ATB = 180°

               65° + 65° + z = 180°

                                  z = 50°

We know that the radius and tangent of circle make 90°.

And the angle sum of quadrilateral is 360°.

∠TAC + ∠TBC + ∠ATB + ∠ACB = 360°

                   90° + 90° + 50° + y = 180°

                                                y = 130°

Then the measure of the arc APB will be

x = 360° – 130°

x = 230°

The measure of the arc APB will be 230°.

Then the correct option is D.

Answer:

Step-by-step explanation:

Use distributive property a(b+c) = a*b +a*c

4(-8x + 5) - (-33x - 26) = 4*-8x + 4 *5 - 33x * (-1) - 26*(-1)

                                    = -32x + 20 + 33x + 26

                                    {add like terms}

                                    = -32x + 33x + 20 +26

n^3 + 2n -2

Step-by-step explanation:

Remove the parentheses and simplify:

-8n^3 + 4n - 8 + 7n^3 - 2n + 6

n^3 + 2n -2.

Answer:

Step-by-step explanation:

We have to add the like terms. Like terms are with variables of same power.

-8n³ and 7n³  are like terms , now add the coefficient of n³ , -8 + 7 = -1

-8n³ + 7n³ = -1n³

(-8n³ + 4n - 8) + (7n³ - 2n + 6 )

Combine like terms

= -8n³ + 7n³    + 4n - 2n  - 8 + 6

= -1n³ + 2n - 2

y = -2/3x + 2

Step-by-step explanation:

Hey there!

Well since we already got the y-intercept to find slope we'll use the points,

(3,0) and (0,2).

Formula: [tex]\frac{y^2 - y^1}{x^2 - x^1}[/tex]

Plug in the given points,

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

Slope = -2/3

Slope-intercept: y = -2/3x + 2

Hope this helps :)

Answer:

y = -2/3x + 2  or

2x + 3y  = 6   (standard form).

Step-by-step explanation:

I am assuming you want the equation of the straight line that passes through these 2 points.

The 2 points are (3, 0 ) and (0, 2).

The slope of the line =  (2 - 0) / (0 - 3)

= -2/3.

The equation is y = -2/3x + 2  ( as 2 is the y-intercept).

In standard form this is :

3y = -2x + 6

2x + 3y  = 6.

Answer:

The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].

Step-by-step explanation:

The equation for the area of a triangle ([tex]A_{\bigtriangleup}[/tex]) is:

[tex]A_{\bigtriangleup} = \frac{1}{2}\cdot b \cdot h[/tex]

Where:

[tex]b[/tex] - Base, dimensionless.

[tex]h[/tex] - Height, dimensionless.

The expression for each triangle are described below:

First Triangle ([tex]b = 3\cdot x + 7[/tex], [tex]h = 5\cdot x - 1[/tex])

[tex]A_{\bigtriangleup,1} = \frac{1}{2}\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]

Second Triangle ([tex]b = 3\cdot (3\cdot x+7)[/tex], [tex]h = 2\cdot (5\cdot x -1)[/tex])

[tex]A_{\bigtriangleup,2} = 3\cdot (3\cdot x+7)\cdot (5\cdot x -1)[/tex]

The difference between the area of the original triangle and the area of the new triangle is:

[tex]\Delta A_{\bigtriangleup} = A_{\bigtriangleup,2}-A_{\bigtriangleup,1}[/tex]

[tex]\Delta A_{\bigtriangleup} = 3\cdot (3\cdot x+7)\cdot (5\cdot x-1)-\frac{1}{2} \cdot (3\cdot x+7)\cdot (5\cdot x-1)[/tex]

[tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex]

The difference between the area of the original triangle and the area of the new triangle is [tex]\Delta A_{\bigtriangleup} = \frac{5}{2}\cdot (3\cdot x +7)\cdot (5\cdot x -1)[/tex].

Answer:

x = 85

Step-by-step explanation:

Step 1: Solve x

∠x = 180 - 27 - 68

∠x = 85

Therefore angle x equals 85

Answer:

85 degrees

Step-by-step explanation:

The sum of the angles of a triangle always add up to 180 degrees.

Here, we have two angles already given, so we can write:

27 + 68 + x = 180

95 + x = 180

Subtract 95 from both sides:

x = 180 - 95 = 85

The answer is thus 85 degrees.

Answer:

[tex]T_{12} = 354294 + 354294i[/tex]

Step-by-step explanation:

Given

Geometric Sequence (GP)

[tex]T_1 = 2 + 2i[/tex]

[tex]r = 3[/tex]

Required

Determine T₁₂

The nth term of a GP is calculated as thus;

[tex]T_n = ar^{n-1}[/tex]

In this case;

[tex]n = 12[/tex];  [tex]r = 3[/tex] and [tex]a = T_1 = 2 + 2i[/tex]

Substitute these values in the above formula

[tex]T_{12} = (2 + 2i) * 3^{12-1}[/tex]

[tex]T_{12} = (2 + 2i) * 3^{11}[/tex]

[tex]T_{12} = (2 + 2i) * 177147[/tex]

Open the bracket

[tex]T_{12} = 177147 * 2 + 177147 * 2i[/tex]

[tex]T_{12} = 354294 + 354294i[/tex]

Hence, the 12th term of the sequence is [tex]T_{12} = 354294 + 354294i[/tex]

Answer:

v = 1.62 m/s

Step-by-step explanation:

Given that,

Distance covered by the mouse is 5.56 m is in 3.42 seconds.

We need to find the velocity of the mouse. It is equal to the total distance covered divided by time taken. So,

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{5.56\ m}{3.42\ s}\\\\v=1.62\ m/s[/tex]

So, the velocity is 1.62 m/s.

Answer:

In the given quadrilateral, two angles measure 60° and other two angles measure 120°.

Step-by-step explanation:

As we know sum of all interior angles of a polygon with 'n' sides is,

Sum of interior angles = (n - 2) × 180°

                                     = (4 - 2) × 180° [for a polygon with n = 4]

                                     = 360°

a + a + 2a + 2a = 360°

6a = 360°

x = 60°

Measure of angles = a° = 60°

And angles having measure = 2a° = 2(60)°

                                               = 120°

Therefore, in the given quadrilateral, two angles measure 60° and other two angles measure 120°.
