Answer:
Rate = 13.173% per year
Step-by-step explanation:
**Not 100% sure about this answer, but I think it's right.**
Calculation Steps:
Solving for rate r as a decimal
r = n[(A/P)^1/^nt - 1]
r = 1 × [(668.00/359.80)^1/^(1)^(5) - 1]
r = 0.131731
Then convert r to R as a percentage
R = r * 100
R = 0.131731 * 100
R = 13.173%/year
If the q is: are 4z2-22 and 4 equivalent expressions, the answer is No.
4z2-22=4
8z-22 is not equal to 4
If you are looking for value of z, then:
8z-22=4
8z=4+22
8z=26
z=26/8
z=13/4
In case in which z=13/4, than expression
4z2-22 would be equivalent to 4.
Hope this helped.
Answer:
3 gallons, i think
Step-by-step explanation:
1+1=2
1/4+3/4=4/4
2 4/4= 3
It does not necessarily mean that the height will rise although I it could rise.this is because volume is what is inside your shape. It could spread out more and have more volume. If you think I'm smart let me tell you I'm only in 4th grade not bragging
Answer: Choice B
(-2, 5)
==================================================
Explanation:
The original system is
Multiply both sides of the second equation by 3. Doing so leads to this updated system of equations
Now add straight down
The x terms add to -4x+3x = -1x = -x
The y terms add to 3y+(-3y) = 0y = 0
The terms on the right hand sides add to 23+(-21) = 2
We end up with the equation -x = 2 which solves to x = -2
Now use this to find y. You can pick any equation with x,y in it
----------------
-4x+3y = 23
-4(-2)+3y = 23
8+3y = 23
3y = 23-8
3y = 15
y = 15/3
y = 5
Or
x-y = -7
-2-y = -7
-y = -7+2
y = -5
y = 5
Either way, we get the same y value.
So that's why the solution is (x,y) = (-2, 5)
