Answer:
Diana will be able to maek 12
Step-by-step explanation:
Your answer is 6% of x.
We can write the given information as equations to find the answer:
Another way to write "20% of x" is to write 0.2x, so therefore 0.2x = y
You can also write "30% of y" as 0.3y, so 0.3y = z
Now we can substitute in the first equation to the second equation, as we know what y equals in terms of x:
0.3(0.2x) = z
Multiplying out we get:
0.06x = z, and 0.06 as a percentage is 6%
I hope this helps!
Answer:
car b has a steeper slope tho... so it's car b
Explanation:
You want to first to substitute to form 3 equations.
5=4a+2b+c
12=9a+3b+c
-4=a-b+c
Now solve with whatever way you fell comfortable, I'm going to use elimination.
First eliminate c
7=5a+b
16=8a+4b --> 4=2a+b
Then I'll eliminate b,
3=3a
a=1
Now solve for b and c
7=5+b
b=2
1-2+c=-4
c=-3
Now for the equation:
y=x^2+2b-3
Hope this helps!
Answer:
(0, 24]
Step-by-step explanation:
The horizontal extent of the graph is from 0 to 24. There is an open circle at x=0, and a closed circle at x=24. Hence, the domain of the function is ...
0 < x ≤ 24
In interval notation, this is
(0, 24]
