<span>y-intercept when x = 0
</span>so
y = -7x + 1
y = -7(0) +1
y = 1
we are given

Firstly, we will simplify left side
and then we can solve for k
Left side is

we can arrange like terms



now, we can use property of exponent



now, we can equate it with right side
and we get

We can see that both sides have 30 , a and b
and they are equal
so, exponent of a must also be equal

now, we can solve for k

................Answer
I got y = two over three x
The yearly fee can be subtracted, resulting in 170-25.50=144.5
So with 10.50 a session, you must divide, resulting in around 13.8 sessions.
13 sessions if you need a whole number.
Hope this helps
Answer:
attached below
Step-by-step explanation:
Attached below are the Venn diagrams
A : 48 < X < 52 cm
B : 9 < Y < 11 cm
a) A
b) A ∩ B
c) A' ∪ B
d) A ∪ B
e) for events to be mutually exclusive it means that both events can not occur simultaneously i.e. A ∩ B = 0
the process would not be successful hence the process would not produce parts with X = 50 cm and Y = 10 cm
