Answer:
you have a fixed rate of $25, meaning you get a haircut, it's $25
ANY other service is an extra $15
So, let's make the equation...
y=15x+25
Now, to just get a haircut it's $25.
But, let's say you get a haircut+shampoo
It'd be..
y=15(1)+25
y=$40
Another one..
You get a haircut+shampoo+highlight
y=15(3)+25
y=$70
Because this triangle is a right traingle and has one angel that is 45 degrees, the third angle must be 45 degrees to because 90+45+45=180. With that, km must be the same length as lm. we know lm is 5 so km is 5 too. No we can plug this into the Pythagorean Theorem too get
5^2+5^2=c^2
25+25=c^2
50=c^2
√50=√c^2
√25*2=c
5√2=c
Thats your answer to the length of lk.
Given that the expression for Julia's salary after t years is given by:
25000(1.04)^t
This can be interpreted as follows:
Initial salary is $25000
growth rate is 0.04=4%
thus the correct answer is:
<span>D salary is 25,000 growth rate is 4% per yr</span>
31 = -4v - 5
31 (+5) = -4v -5 (+5)
36 = -4v
36/(-4) = -4v/(-4)
36/ -4 = v
v = -9 is your answer
hope this helps
