Molly and George earned 352 points together. Molly has half the number of points as George. Which equation could represent this

Kitty [74]

Answer: A. g+2g =352

Step-by-step explanation:

Let points : g

If molly has half of George then let

Let molly : 1

Let George: 2

Therefore g*1 =g

And g*2 = 2g

So, g+2g = 352

Which graph represents the function of f(x) = the quantity of 9 x squared plus 9 x minus 18, all over 3 x plus 6

lora16 [44]

Answer:

The answer is the option C

graph of $3x$ minus $3$ , with discontinuity at negative $2$ , negative $9$

Step-by-step explanation:

we have

$f(x)=\frac{9x^{2}+9x-18}{3x+6}$

Simplify

$f(x)=9\frac{(x^{2}+x-2)}{3(x+2)}$

$f(x)=3\frac{(x^{2}+x-2)}{(x+2)}$

Step 1

Convert to a factored form the numerator

$x^{2}+x-2=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2}+x=2$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$x^{2}+x+0.25=2+0.25$

$x^{2}+x+0.25=2.25$

Rewrite as perfect squares

$(x+0.5)^{2}=2.25$

Square root both sides

$x+0.5=(+/-)1.5$

$x=-0.5(+/-)1.5$

$x=-0.5+1.5=1$

$x=-0.5-1.5=-2$

$x^{2}+x-2=(x-1)(x+2)$

Step 2

Simplify the function f(x)

$f(x)=3\frac{(x^{2}+x-2)}{(x+2)}=3\frac{(x-1)(x+2)}{(x+2)}$

The domain of the function f(x) is all real numbers except the number $x=-2$

Because the denominator can not be zero

$f(x)=3\frac{(x-1)(x+2)}{(x+2)}=3(x-1)=3x-3$

$f(x)=3x-3$ ------> with a discontinuity at $x=-2$

$f(-2)=3(-2)-3=-9$

The discontinuity is at point $(-2,-9)$

Marcus was going up 10 stairs in his office. Write an absolute value expression for the given statement.

djyliett [7]

The absolute value expression for the given statement is |10|

<h3>What is absolute value?</h3>

The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign

Marcus was going up stairs in his office. Therefore, he was ascending .

This means the 10 staircase will be added since there is an increase.

Hence, the absolute value expression for the given statement is as follows:

absolute value = |10|
