3(2x + 1) + 2(x + 3)​

Answer:

Kindly check explanation

Step-by-step explanation:

Length of parking lot = 20 feets

Speed of tortoise which starts at the edge = 6 feets per minute

Speed of tortoise which starts 4 feets from the edge = 2 feets per minute

Equation to represent when they will be in the same spot.

Distance = speed * time

Distance of Tortoise at edge = 6ft/min * t = 6t - - (1)

Distance of the other tortoise = (4 + 2t) - - - (2)

Equating both (1) and (2)

6t = 4 + 2t

6t - 2t = 4

4t = 4

t = 4/4

t = 1

Hence, they'll be at the same spot after 1 minute.

Let's find the value of x

x + 5 = 20

Subtract 5 from both sides

x = 15

x + 10 = 15 + 10 = 25

Answer:

B  17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.

Answer:9

Step-by-step explanation:

I did the math

Given:

Able's age can be represented by x.

Able's sister is 4 years younger than him.

Able's older brother is twice as old as he is.

The combined age of all three siblings is 32.

To find:

The age of Able's younger sister.

Solution:

Able's age can be represented by x.

Able's sister is 4 years younger than him.

Age of Able's sister = (x-4)

Able's older brother is twice as old as he is.

Age of Able's older brother = 2x

The combined age of all three siblings is 32.

Add 4 on both sides.

Divide both sides by 4.

The age of Able is 9 years. So, age of his younger sister is

Therefore, the age of Able's sister is 5 years.

Answer:

3/16

Step-by-step explanation:

Answer:

  1. (-∞, ∞), [-4, ∞), (2, ∞), (-∞, 2), (-∞, 0) ∪ (4, ∞), (0, 4), DNE, -4, 2

  2. y = -|x -4| -2

Step-by-step explanation:

1.

a. the domain is the horizontal extent, (-∞, ∞)

b. the range is the vertical extent, [-4, ∞)

c. the function is increasing where it goes up to the right, (2, ∞)

d. the function is decreasing where it goes down to the right, (-∞, 2)

e. the function is positive where it is above the x-axis, (-∞, 0) ∪ (4, ∞)

f. the function is negative where it is below the x-axis, (0, 4)

g. the function extends to ∞, so has no maximum value

h. the vertex is the low point, or minimum value, -4

i. the function increases from -4 to 0 on the interval [2, 4] so has an average rate of change of (0 -(-4))/(4 -2) = 4/2 = 2

__

2. Reflection across the x-axis negates every y-value. Multiply the given function by -1:

  y = -|x-4| -2

Answer:

Plug the points into an equation

Step-by-step explanation:

To find out if a point is on a line, you can plug the points back into an equation. If the values equal one another, then the point must be on a line.

Answer:

To determine if a point is on a line you can subsitute the x and y coordinates into the equation.. If the values equal one another, then the point must be on a line.

Step-by-step explanation:

For example if the x - 3y = 11 and the point is (2, -3) plug in

2 - 3(-3) = 11

2 + 9 = 11

11 = 11

Answer:

D. Rotation 270 degrees clockwise.

Step-by-step explanation:

The transformation used in the coordinates below was a rotation 270 degrees clockwise, whose definition is:

[tex](x', y') = (r\cdot \cos (\theta - 270^{\circ}), r\cdot \sin (\theta -270^{\circ}))[/tex]

Please note that clockwise rotation is represented by the minus sign.

Where [tex]r[/tex] is the norm of original point, defined as:

[tex]r =\sqrt{x^{2}+y^{2}}[/tex], [tex]\forall \,x,y\in \mathbb{R}[/tex]

And [tex]\theta[/tex] is the direction of the point centered at origin and with respect to +x semiaxis, measured in sexagesimal degrees:

[tex]\theta = \tan^{-1} \frac{y}{x}[/tex]

Now we proceed to prove the statement:

[tex]L (x, y) = (-1, 9) \longrightarrow L'(x,y)[/tex]

Norm

[tex]r = \sqrt{(-1)^{2}+9^{2}}[/tex]

[tex]r = \sqrt{82}[/tex]

Direction

The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:

[tex]\theta = \tan^{-1}\left(\frac{9}{-1} \right)[/tex]

[tex]\theta = 96.340^{\circ}[/tex]

Rotation

[tex]L'(x,y) = (\sqrt{82}\cdot \cos (96.340^{\circ}-270^{\circ}),\sqrt{82}\cdot \sin (96.340^{\circ}-270^{\circ}))[/tex]

[tex]L'(x,y) = (-9, -1)[/tex]

[tex]M(x,y) = (-8,8) \longrightarrow M'(x,y)[/tex]

Norm

[tex]r = \sqrt{(-8)^{2}+8^{2}}[/tex]

[tex]r = \sqrt{128}[/tex]

Direction

The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:

[tex]\theta = \tan^{-1}\left(\frac{8}{-8} \right)[/tex]

[tex]\theta = 135^{\circ}[/tex]

Rotation

[tex]M'(x,y) = (\sqrt{128}\cdot \cos (135^{\circ}-270^{\circ}),\sqrt{128}\cdot \sin (135^{\circ}-270^{\circ}))[/tex]

[tex]M'(x,y) = (-8, -8)[/tex]

[tex]N(x,y) = (-3,5)\longrightarrow N'(x,y)[/tex]

Norm

[tex]r = \sqrt{(-3)^{2}+5^{2}}[/tex]

[tex]r =\sqrt{34}[/tex]

Direction

The point is located on 2nd quadrant, which means that [tex]90^{\circ} \leq \theta \leq 180^{\circ}[/tex]. Then:

[tex]\theta = \tan^{-1}\left(\frac{5}{-3} \right)[/tex]

[tex]\theta = 120.964^{\circ}[/tex]

Rotation

[tex]N'(x,y) = (\sqrt{34}\cdot \cos (120.964^{\circ}-270^{\circ}), \sqrt{34}\cdot \cos (120.964^{\circ}-270^{\circ}))[/tex]

[tex]N'(x,y) = (-5, -3)[/tex]

Hence, the correct answer is D.

Answer: m<A = 35

Step-by-step explanation: The sum of the measures

of the interior angles of a triangle is 180°.

So we can setup the equation 3x + 5 + 8x + 65 = 180.

Combining our numbers and variables on the left, we have 11x + 70 = 180.

Now subtract 70 from both sides to get 11x = 110.

Dividing both sides by 11, we find that x = 10.

In the diagram, the m<A is represented as 3x + 5.

Plugging a 10 in for x, we have 3(10) + 5 or 30 + 5 which is 35.

So the m<A = 35.

Answer:B

Step-by-step explanation:

Answer:

x=10

Step-by-step explanation:

move all terms that don't contain x to the right side and solve.

Sum of interior angles in quadlateral (trapezoid) is 360 degrees.

[tex]5y+2+8y+73+2y=360[/tex].

Simplify by collecting y terms and subtracting 73 on the other side.

[tex]15y+75=360\implies y=285/15=\boxed{19}[/tex].

Hope this helps.
