4^(x^2-3x)=256
First
256=4^4
4^(x^2-3x)= 4^4 a^x=a^y x=y
X^2-3x=4
X^2-3x-4=0 by using quadratic formula
x = (-b ± √(b2 − 4ac))/(2a)
=-(-3) ±√((-3)2 − 4(1 )(-4)/(2(1))
= (3 ±√(9 + 16))/2
= (3 ±√(25))/2
= (3 ±5)/2
X= 4 or -1

Find(f+g)(x) for the following functions. f(x) = 12x2 + 7x + 2 g(x) = 9x + 7
Nimfa-mama [501]

Answer:

(f + g)(x) = 12x² + 16x + 9 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- We can add and subtract two function by adding and subtracting their

 like terms

Ex: If f(x) = 2x + 3 and g(x) = 5 - 7x, then

     (f + g)(x) = 2x + 3 + 5 - 7x = 8 - 5x

     (f - g)(x) = 2x + 3 - (5 - 7x) = 2x + 3 - 5 + 7x = 9x - 2

* Lets solve the problem

∵ f(x) = 12x² + 7x + 2

∵ g(x) = 9x + 7

- To find (f + g)(x) add their like terms

∴ (f + g)(x) = (12x² + 7x + 2) + (9x + 7)

∵ 7x and 9x are like terms

∵ 2 and 7 are like terms

∴ (f + g)(x) = 12x² + (7x + 9x) + (2 + 7)

∴ (f + g)(x) = 12x² + 16x + 9

* (f + g)(x) = 12x² + 16x + 9

Kiera is in her last year of college at the University of Houston. She has a scholarship that pays 75% of her costs. Her classes
sergiy2304 [10]
If the scholarship pays 75% of her classes cost, that means that she has to pay the 25% remaining of the classes cost so if we calculate it as follow:

0.25 * $14,000 = $3,500 
 =================================================================
Another method to understand:
if the scolarship pays 75% of her classes that will be 
0.75* $14,000 = $10,500

now she has to pay the remaining of the total cost and that will be 
$14,000 - $10,500 = $3,500.
