Divide by 1.8
x = around 35.56
Answer:
vertex = (3, 4 )
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
y = - (x - 3)² + 4 ← is in vertex form
with (h, k ) = (3, 4 ) ← vertex
Answer:
Step-by-step explanation:
Both equations have -7y. You can eliminate them by subtracting one equation from the other:
Multiply equation 1 by -1, then add it to equation 2:
-2x + 7y = 74
3x - 7y = -83
———————
x = -9
2x - 7y = -74
2(-9) - 7y = -74
-7y = -56
Y = 8
(x,y) = (-9, 8)
Answer:
angle E, the measure is 135
angle J, the measure is 105
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
We are to identify an angle that is supplementary to angle M form the given parallel line.
From the fist diagram, angle E and angle F are supplementary to angle M because they form adjacent angles on a straight line with angle M.
If angle m is 45 degrees, then the value of its supplement is 180-45=135
From the second diagram, angle H,angle J and angle P are supplementary to angle M.
If angle M is 75 degrees, the its supplement is 180-75=105
