First start by subtracting:
50-8=42
the new equation is:
6x=42
then divide:
42/6=7
So the answer is:
x=7
Hope this helps!! :D
Answer:
The discriminant is:
b
2
−
4
a
c
a
=
1
b
=
12
c
=
36
Substitute these values into the discriminant and you should get two answers (real roots):
12
2
−
4
(
1
)
(
36
)
=
0
If the discriminant is 0 there is 1 real root, if it is > 0 there are 2 and otherwise 0 real roots.

Im pretty sure this is it, hope I could help
The first one is y=4x+-11. The second one is y=-5/2x+2
Answer:
$80
Step-by-step explanation:
First I'll ask (cause I'm not an expert at english)(and I'm a child)
Additional fee for maintenance is a thing you pay every month right?
In that case,
Monthly fee per month (m): 11
Additional fee per month (a): 9
Total fee per month (t): [m+a] or [11+9]
Total fee for 4 months (x): (11+9)x4=80
Customers will have to pay $80 after 4 months.
Answer:
4 radians
Step-by-step explanation:
Arc Length (Radians) = rθ
Given Arc Length XY = 40cm and radius, r = 10cm,
we will substitute these 2 values into the formula to find θ.
(10)θ = 40
θ = 40 / 10
= 4 radians
