Answer:
ABC = 44°
Step-by-step explanation:
ABD = 96° and EBD = 26°
Since BE bisects CBD, this means that BE cuts the angle in half, so:
CBE = 26° EBD = 26°
Add these two angles and subtract from the entire angle of ABD:
ABD - (CBE + EBD) = ABC
96° - (26° + 26°) = ABC
96° - 52° = 44°
ABC = 44°
Answer:
On a coordinate plane, a parabola opens up
It goes through (negative 3, 0), has a vertex at (negative 0.5, negative 6.25), and goes through (2, 0).
Step-by-step explanation:
f(x) = (x + 3)(x – 2)
We know that parabola opens up since the x^2 term is be positive
it has zeros at x=-3 and x=2
x+3 =0 and x-2 =0 from the zero product property
The vertex is halfway between the zeros
(-3+2)/2 = -1/2
x=-1/2
f(-1/2) = (-1/2+3) (-1/2-2) = 2.5 * -2.5 =-6.25
The vertex is (-1/2, -6.25)
47 - 19 = 28
28/4 = 7
At most they can spend 7 hours
The solution is
T = (47-19)/4
T = 28/4
T = 7
I think that solution is what your teacher is asking for, i'm not certain but ik the answer should be 7 hours.
Answer:
127.28
Step-by-step explanation:
that is your answer :)
X - y = -3
Move constant to the left by adding its opposite to both sides
x - y + 3 = -3 + 3
The sum of two opposites equals
your answer would be: x - y + 3 = 0
