Answer:
i dont think you can solve this because
The expression is not factorable with rational numbers.
there are no like terms
is the question multiple choice? if not I'd go with absolute value
Divide the amount you need to invest by the percentage.
430/0.05 = 8,600
You earned $8,600
This is a parabola, meaning the equation is a quadratic, so it has 2 roots or x-intercepts, keeping in mind that vertex will lie half-way between those intercepts.
so what's the x-value halfway between -3 and 7? yeap, you guessed it, 2.
so the axis of symmetry for this vertical parabola will be at x = 2.
Answer: x > 74
<u>Step-by-step explanation:</u>
An obtuse angle is greater than 180°. So, 3x - 42 must be greater than 180.
- 3x - 42 > 180
- <u> +42 +42</u>
- 3x > 222
- <u>÷3 ÷3</u>
- x > 74
