Ulleksa [173]

Answer:

Step-by-step explanation:

(f + g)(x) simply means that you are adding together the 2 functions that are written in terms of x.

x^3-x+x^3+2x^2-10

The only like terms we have there are the x-cubed's, so

2x^3+2x^2-x-10=(f+g)(x)

marin [14]

Answer:

\begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{1200}{499}\:\\ \:\mathrm{Decimal:}&\:x\le \:2.40480\dots \\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{1200}{499}]\end{bmatrix}

Step-by-step explanation:

20\ge \:8+4.99x\\Switch\:sides\\8+4.99x\le \:20\\\mathrm{Multiply\:both\:sides\:by\:}100\\8\cdot \:100+4.99x\cdot \:100\le \:20\cdot \:100\\Refine\\800+499x\le \:2000\\\mathrm{Subtract\:}800\mathrm{\:from\:both\:sides}\\800+499x-800\le \:2000-800\\Simplify\\499x\le \:1200\\\mathrm{Divide\:both\:sides\:by\:}499\\\frac{499x}{499}\le \frac{1200}{499}\\Simplify\geq \\x\le \frac{1200}{499}

Which of the expressions below can be factored using the difference of squares method?
Dmitry [639]

Answer: A. 9x^2 - 16y^2 .

Step-by-step explanation:

  • A difference of squares problem is factored as :a^2 - b^2 = (a + b)(a - b)
  • For this both terms in the form of squares and a minus sign between them.

From all the options only option A has both terms square and they minus sign between them.

Also, 9x^2 - 16y^2= (3x)^2-(4y)^2=(3x+4y)(3x-4y)

Here a= 3x and b= 4

Hence, the correct answer is A. 9x^2 - 16y^2 .

Monica is a lawyer who earns $8,322.65 every month. She spends $830.98 on rent, $210.36 on food, and $120.45 on gas every month.
Step2247 [10]
She would have $7160.86 left over in cash here's why.....
she starts off with $8,322.65 and spends $830.98 on rent $8,322.65-$830.98= $7,491.67 
then spends $210.36 on food and another $120.45 on gas 
$7,491.67-$210.36= $7,281.31 - $120.45= $7,160.86 <---- Left over $
