Answer:

x=2.5

Step-by-step explanation:

P=(3x+1)+(x+1)+(3x+1)+(x+1)

24=3x+1+x+1+3x+1+x+1

24=8x+4

24-4=8x

20=8x

x=20/8

x=2.5

P=(3*2.5+1)+(2.5+1)+(3*2.5+1)+(2.5+1)

P=8.5+3.5+8.5+3.5

P=24

Instructions: Find the measure of the indicated angle to the nearest degree.
sweet-ann [11.9K]

The measure of the indicated angle to the nearest degree is 47°.

<h3>What is the measure of the angle?</h3>

Given the data in the question;

  • Adjacent = 36
  • Hypotenuse = 53
  • Angle θ = ?

From trigonometric ratio, Cosθ = Adjacent / Hypotenuse

Cosθ = 36/53

θ = cos⁻¹( 36/53 )

θ = 47°

Therefore, the measure of the indicated angle to the nearest degree is 47°.

Triangle ABC has vertices A(4, 5), B(0, 5), and C(3, –1). The triangle is translated 3 units to the left and 1 unit up. What are
Galina-37 [17]

Answer:

B' = (-3,6)

Step-by-step explanation:

Given

A(4,5)

B(0,5)

C(3,-1)

<em>Translation: 3 units left and 1 unit right</em>

Required

Determine the new coordinates of B

Write out the coordinates of B

x = 0

y = 5

When a function is shifted to the left, we have to subtract the unit from the x value of the function;

<em>Shifting by 3 units left, the new x becomes </em>

<em />New\ x = 0 - 3<em />

<em />New\ x = -3<em />

<em />

When a function is shifted upward, we have to add the unit to the y value of the function;

<em>Shifting by 1 unit up, the new y becomes </em>

New\ y = 5 + 1

New\ y = 6

Hence, the new coordinates of B is

B' = (-3,6)

Using the point-slope formula, what is the equation of the line that passes through the points (1,5) and (0, 0)?
DerKrebs [107]

Answer:

y =5x

Step-by-step explanation:

y_{1}-y_{2}  = m(x_{1} - x_{2} )

(5 - 0) = m(1 - 0)

5 = m(1)

5 = m

y_{1}-y_{2}  = m(x_{1} - x_{2} )

y - 5 = 5(x - 1)

y - 5 = 5x - 5

y = 5x -5 + 5

y = 5x

If a =3x^2+5x-6 and b =-2x^2 -6x+7 then A - B equals
gizmo_the_mogwai [7]

Answer:

5x^2+11x-13

Step-by-step explanation:

a=3x^2+5x-6\\b=-2x^2-6x+7

a-b=(3x^2+5x-6)-(-2x^2-6x+7)=\\3x^2+5x-6+2x^2+6x-7=\\5x^2+11x-13

Hope this helps!
