Alright, I'm pretty sure I can help.
Let's look at the first answer choice.
7 - 2 (m + 1)
Distribute -2 and add the remaining numbers to get the total for that answer choice.
7 - 2m - 2
Simplify. You get 5 - 2m.
Looks like we found the answer on the first choice!
The Final Answer is 7 - 2 (m + 1)
Answer:
x = 7.2
Step-by-step explanation:
42=5x+6
42-6=5x
36=5x
36/5=x
7.2=x
Check your solution:
5(7.2)+6
36+6
42
5(7.2)+6 = 42
hope this helps!
You use the first formula. You plug in the values to get A=400(1+(0.05/1))^6. You should get approximately $536.04. I used 0.05 because you need to change the percent to a decimal, and 1 for n because it is compounded annually, meaning once a year.
I can’t see the top of the image. Can you make it more upper a little? I think it is 9
4x² + 3x + 5 = 0
x = <u>-3 +/- √(3² - 4(4)(5))</u>
2(4)
x = <u>-3 +/- √(9 - 80)</u>
8
x = <u>-3 +/- √(-71)
</u> 8<u>
</u>x = <u>-3 +/- √(71 × (-1))</u>
8
x = <u>-3 +/- √(71) × √(-1)
</u> 8<u>
</u>x = <u>-3 +/- 8.43i
</u> 8
x = -0.375 +/- 1.05375i
x = -0.375 + 1.05375i x = -0.375 - 1.05375i
