Answer:
14
Step-by-step explanation:
k
=
c
−
b
2
4
a
We know that
a
=
1
,
b
=
−
8
and
c
=
2
, so let's substitute:
k
=
2
−
(
−
8
)
2
4
(
1
)
=
2
−
64
4
=
2
−
16
=
−
14
.
So, we have
min
=
−
14
. Let's check:
graph{(x^2 - 8x + 2 - y)(-14 -y)=0 [-11.82, 20.22, -15.38, 0.64]}
Your answer could be b or d but I think it is b using the equation y=mx +b
Answer:
32
Step-by-step explanation:
First, combine like terms
4x+7=6x-9
+9 +9
4x+16=-9
-16 -16
Then divide by four to isolate x
4x=-25
x=-6.25
Plug in X to get the angle measure .
The answer is 29.5
Okkkkkkkkrrrrrrrr It is a long division just use calculator
