Answer:
a)5/x+1/4=6
Step-by-step explanation:
R=number of hours ruby worked
i=number of hours issac worked
s=number of hours shetland worked
ruby worked 8 more than issac
r=8+i
shetland worked 4 times as many as ruby
s=4r
total they worked 136
r+i+s=136
so
we gots
r=8+i
s=4r
for r=8+i
solve for i
minus 8 both sides
r-8=i
so
r+i+s=136
subsitute r-8 for i and 4r for s
r+r-8+4r=136
6r-8=136
add 8 to both sides
6r=144
divide both sides by 6
r=24
sub back
r-8=i
24-8=i
16=i
s=4r
s=4(24)
s=96
ruby worked 24 hours
issac worked 16 hours
shetland worked 96 hours
Answer:
I'm a little rusty on this type of math, but I'll answer to the best of my ability.
Step-by-step explanation:
They will be similar. I have no idea on the scale factor, and the angle pair is DAC = EAB
I'm sorry I couldn't help more.
Answer:
No restriction
Domain:
Step-by-step explanation:
We are given function as
we know that this is exponential function
and x+4 as an exponent over e
so, we can select any real values of x as an exponent
and this function will be defined for all values of x
so, there won't be any value of x where f(x) is undefined
So, domain would be
