Answer:

  • x > 6
  • 6 < x < 62

Step-by-step explanation:

<h3>Question 5</h3>

The sides containing the given angles 37 and 84 are of same length:

one side is marked same, the second side is common.

<u>The sides opposite angles of 37 and 84 are proportional to those angles, therefore:</u>

  • 0< x + 14 < 2(3x - 8)

<u>The first part:</u>

  • x > - 14

<u>The second part:</u>

  • x + 14 < 6x - 16
  • 5x > 30
  • x > 6

<u>Combination of the two is:</u>

  • x > 6
<h3>Question 6</h3>

<u>The triangles are isosceles, because:</u>

  • The left triangle has two equal angles, so the opposite sides are congruent
  • The common side with the right triangle is same as marked side, so the triangle on the right is also isosceles.

The angles between equal sides

<u>Left triangle:</u>

  • 180° - 2*70° = 40°

<u>Right triangle:</u>

  • 180° - 2*66° = 48°

<u>Since 40° < 48°, the opposite sides will have same inequality due to being proportional to angles:</u>

  • 3x - 18 < 2(x + 22)
  • 3x - 18 < 2x + 44
  • 3x - 2x < 44 + 18
  • x < 62

<u>Same time we know the side must be a positive number:</u>

  • 3x - 18 > 0
  • 3x > 18
  • x > 6

<u>So the possible values of x are:</u>

  • 6 < x < 62 or x = (6, 62)

What is the surface area of this right rectangular prism? Enter your answer as a
mixas84 [53]

You will find all of the surface area of all of the sides and add them together to find the surface area of the retangular prisim. So, what I would do is the front and back are both 54, so 108. The sides are 27, so 54. The top and bottom are 18, so 36. Add them together, and you will get 198. I hope this helps.

Write an equation for the line passing through the points (-5,15) and (20,25). Show how you found your answer.
olasank [31]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-5, 15) and (20, 25). substitute:

m=\dfrac{25-15}{20-(-5)}=\dfrac{10}{25}=\dfrac{2}{5}\\\\y-15=\dfrac{2}{5}(x-(-5))\\\\y-15=\dfrac{2}{5}(x+5)\qquad|\text{use distributive property}\\\\y-15=\dfrac{2}{5}x+2\qquad|\text{add 15 from both sides}\\\\y=\dfrac{2}{5}x+17\qquad|\text{multiply both sides by 5}\\\\5y=2x+85\qquad|\text{subtract 2x from both sides}\\\\-2x+5y=85\qquad|\text{change the signs}\\\\2x-5y=-85

Answer:

point-slope form: y-15=\dfrac{2}{5}(x+5)

slope-intercept form: y=\dfrac{2}{5}x+17

standard form: 2x-5y=-85

What is the image of point (4, 5) after a counterclockwise rotation of 270º about the origin?
andriy [413]
A <span>counterclockwise rotation of 270º about the origin is equivalent to a </span><span>clockwise rotation of 90º about the origin.

Given a point (4, 5), the x-value, i.e. 4 and the y-value, i.e. 5 are positive, hence the point is in the 1st quadrant of the xy-plane.

A clockwise rotation of </span><span>90º about the origin of a point in the first quadrant of the xy-plane will have its image in the fourth quadrant of the xy-plane. Thus the x-value of the image remains positive but the y-value of the image changes to negative.
Also the x-value and the y-value of the original figure is interchanged.
For example, given a point (a, b) in the first quadrant of the xy-plane, </span><span>a counterclockwise rotation of 270º about the origin which is equivalent to a <span>clockwise rotation of 90º about the origin will result in an image with the coordinate of (b, -a)</span>

Therefore, a </span><span>counterclockwise rotation of 270º about the origin </span><span>of the point (4, 5) will result in an image with the coordinate of (5, -4)</span> (option C)
