<h2>
Answer: 2x³ - 3x² + 7x + 8</h2>
Step-by-step explanation:
Sum = 4x³ - 3x² + 3x + 8 + (6x³ - 7x² + 4x) + (-8x³ + 7x²) <em>[write the terms as given by the quetion and group like terms]</em>
<em />
⇒ Sum = (4x³ + 6x³ - 8x³) + (- 3x² - 7x² + 7x²) + ( 3x + 4x) + 8 <em> [complete the addition of like terms]</em>
<em />
∴ sum = 2x³ - 3x² + 7x + 8
I belive it is c if i am correct im not really sure
Answer:
Step-by-step explanation:
To find the inverse of a function, take your equation and <u>switch the "x" and "y" variables. Then, isolate "y"</u>.
Take your equation
y = 2x - 11
Switch "x" and "y" variabales
x = 2y - 11
Isolate "y", meaning to move it to the left, and everything else to the right. When moving a number, do its reverse operation to both sides of the equation.
x = 2y - 11 Move "-11" first. It's reverse is +11
x + 11 = 2y - 11 + 11 Do the reverse to both sides
x + 11 = 2y The reverses cancel out
In "2y", 2 is multiplying with y. The reverse of multiplying is dividing.
Divide both sides by 2
Move "y" to the left for standard formatting
Inverse of y = 2x - 11
Answer:
It can be modeled with the equation but needs a starting population number to finish.
Step-by-step explanation:
To find the population in a future year, use the formula:
where A is the amount, p is the starting population, r is 2% or 0.02, and t is the number of years.
Since the population is increasing it is addition. Substitute r=0.02 and t=6. Without a starting population, we cannot find the population in 6 years.
