Answer:
2z+6
Step-by-step explanation:
you just multiply the z and 3 by 2.
The answers are
focus: (−2,3)
directrix: y=7
vertex: (−2,5)
The vertex is at the point (−2,5), the focus is at the point (−2,3), and the directrix is the line at y=7.
Hope this helps
Answer:
x = 27
Step-by-step explanation:
Based on the angle bisector theorem, we would have the following:
(x + 8)/10 = (2x - 5)/14
Cross multiply
14(x + 8) = 10(2x - 5)
14x + 112 = 20x - 50
Collect like terms
14x - 20x = -112 - 50
-6x = -162
Divide both sides by -6
-6x/-6 = -162/-6
x = 27
Answer:
the answer is<u> no solutions </u>
Step-by-step explanation:
the solution is found at the point in which the two lines intersect.
in this case they do not intersect because the lines are parallel. if you rearrange 2x – y = 7 you will get y = 2x - 7. the slope is 2x
the slope of the second equation is 2x as well. when slopes are the same they are parallel and therefore never cross.
