In order to solve the equation we first need to put the condition:
6x+7>=0
x>= -7/6
We square the equation:
x^2=6x+7
x^2-6x-7=0
x^2+x-7x-7=0
x(x+1)-7(x+1)=0
(x-7)(x+1)=0
x1=7
x2=1
Both solutions meet the condition.
Answer:
Step-by-step explanation:
- Principal = $480
- Interest rate = 7% compounded
- Compound number = 4 per year
- Time = 9 years
<u>Final amount is:</u>
- 480*(1 + 0.07/4)^(9*4) =
- 480(1.0175)^36 =
- $896.36
Answer:
- c) Four times x over four equals four over four; Division Property of Equality
===========================
Given equation and steps to solve it:
- 4(x + 1) = 8
- 4x + 4 = 8
- 4x + 4 - 4 = 8 - 4
- 4x = 4
- 4x/4 = 4/4 <u>This is the missing step</u>
- x = 1
All steps given above including the missing one. As we can see, we divided both sides by 4, so the justification for this step is Division Property of Equality.
Hence, the correct choice is C.
Answer:
3n + 7.6 = 52.6
Step-by-step explanation:
The answer you would get would be x (-x^2-x+4+7x^4)
