Distributive property first so you wanna do 2•4 then you will get 8x then you have to do 2•8 Wich is 16 then you will end up with 8x-16+16t=48 move the expression to the right 8x=48+16-16t 8x=64-16t x=8-2t?
x is time and y is pencils that you have
'starts with 90' so at x=0, plot y=90
'gives away 15 every hour' so for every 1 hour, move 15 down on y
so at x=1, do 90-15=75 pencils
at x=2, do 75-15=60 pencils
etc
until you get to
x=6, do 15-15=0 pencils then stop because you can't give away 15 pencils when you have 0
see attachment for plot
I don't know how your segment tool works so you do it
if it draws a line, you only need 2 points, just do when x=0, y=90 and when x=6, y=0
The approximate solution of the above equation is: 55/15 (Option A). This is solved using the quartic formula, not quadratic equation.
<h3>
What is the Quartic Formula?</h3>
The quartic formula has up to four various solutions including real and imaginary numbers. Read on for more explanation.
<h3>
What is the solution to the above question?</h3>
First we restate the above equation:
x²-3x+2= √(x-2) + 2
Next we remove square roots
- 6x³ + 9x² = x - 2
Add two to both sides
→
- 6x³ + 9x²+2 = x - 2 +2
→
- 6x³ + 9x²+2 = x
Subtract X from both sides
→
- 6x³ + 9x²+2 -x = x -x
→
- 6x³ + 9x²+2 - x= 0
Using the Quartic formula to solve the fourth order equation:
a
+ bx³ + cx² + dx + e
The resolution of x is given as:
x = 2.691085, 3.346753
Because the fraction nearest to 3.4 is 55/16
hence, the correct answer is Option A.
