Answer:

C and D

Step-by-step explanation:

in equations y=4x+9 and y=4x-9 you have the same slope (4) so paralleling is guaranteed.

y=9 and y=18 you can understand as y=0x+9 and y=0x+18, so in this situation you have the same slope (0), so lines y=9 and y=18 are parallel too.

Answers:

  • Vertex
  • 3
  • middle

If an angle is labeled with a single letter, that letter represents the <u>  vertex  </u> of the angle.

If more than one angle has the same vertex, you must use <u>  3   </u> points to name the angle. The <u>  </u><u>middle  </u> point named must be the vertex.

=================================================================

Explanation:

If we have a single triangle, and no other extra lines, then we can use single letters to name the three angles. Each vertex of the triangle corresponds to the vertex of that angle.

If you were to draw many triangles, in which some may or may not overlap, you'll mostly likely need to name the angle using 3 letters. This is so you are very specific about which angle you're talking about. The middle letter is always the vertex. The left and right letters are points on the arms of the angle. The order of the left and right letters doesn't matter as long as the middle letter stays the same. So something like angle ABC is the same as angle CBA.

PLEASE HELP ASAP!!!!!
attashe74 [19]
For this case what we must do is use the law of cosines.
 We then have the following equation:
 c ^ 2 = a ^ 2 + b ^ 2 - 2 * a * b * cos (x)&#10;
 Where,
 a, b: sides of the triangle
 x: angle between sides a and b.
 Substituting values we have:
 c^2 = 90^2 + 75^2 - 2*90*75*cos(85)&#10;
 Clearing the value of c we have:
 c =  \sqrt{ 90^2 + 75^2 - 2*90*75*cos(85)}
 Answer:
 
An expression that is equivalent to how many feet the oak trees are from each other is:
 
c = \sqrt{ 90^2 + 75^2 - 2*90*75*cos(85)}

Zina [86]
Andy runs 7 meters per second.

436.8/62.08 = x/1
436.8/62.08=7.04
7.04/1 =7.0/1

Hope that help!:)

If f(x) = 3x - 2 and g(x) = 2x + 1, find (f - g)(x)
morpeh [17]

Answer:

(f-g)(x) = x-3

Step-by-step explanation:

Given

f(x) = 3x-2

and

g(x) = 2x+1

We have to find (f-g)(x)

So,

(f-g)(x) = f(x)-g(x)

= 3x-2 - (2x+1)

= 3x-2-2x-1

=x-3

Hence,

(f-g)(x) = x-3
