Answer:

Step-by-step explanation:

x² - 10x -24 = (x + 2) (x - 12) ....(1)

x² - 3x - 108 = (x + 9) ( x - 12) ....(2)

(1) / (2) formula (2) can't be 0 ∴ x ≠ -9 and x ≠ 12

(1) / (2) = (x + 2) / (x + 9)

answer is (B)

Leno4ka [110]

Answer:

$171

Step-by-step explanation:

A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?

Let x represent the original price of the pair of pants

From the question, we know that:

10% of x = $17.10

10/100 × x = $17.10

10x/100 = $17.10

Cross Multiply

10x = 100 × $17.10

10x = 1710

x = 1710/10

x = $171

Hence, the original price of the pants = $171

The graph of the quadratic parent function is reflected across the x-axis, then shifted 5 units down and 4 units right. Write th

vredina [299]

Answer:

y = -(x -4)² -5

Step-by-step explanation:

-f(x) is a reflection of f(x) across the x-axis.

f(x) -5 is a translation down by 5 units.

f(x -4) is a translation right by 4 units.

Applying these transformations to y = x² gives, successively, ...

y = -x²

y = -x² -5

y = -(x -4)² -5 . . . . . . the new equation in vertex form

Write the equation of a line in slope-intercept form that is parallel to the given line and passes through the point (12,-25).

lina2011 [118]

Answer:

$m_1 = m_2 = \frac{1}{4}$

And then since the new equation have the following form:

$y = m_2 x +b$

We can use the point given (x=12, y = -25) in order to find the intercept with this equation:

$-25 = \frac{1}{4} (12) +b$

And solving for the intercept b we got:

$-25 = 3 +b$

We subtract in both sides 3 and we got:

$b = -25-3 = -28$

And our final equation who satisfy the condition given is:

$y= \frac{1}{4} x -28$

Step-by-step explanation:

For this case we have the following equation given:

$y = \frac{1}{4} x + 2$

And we want to find an equation of a line parallel to the given function and this case we need to satisfy this condition:

$m_1 = m_2 = \frac{1}{4}$

And then since the new equation have the following form:

$y = m_2 x +b$

We can use the point given (x=12, y = -25) in order to find the intercept with this equation:

$-25 = \frac{1}{4} (12) +b$

And solving for the intercept b we got:

$-25 = 3 +b$

We subtract in both sides 3 and we got:

$b = -25-3 = -28$

And our final equation who satisfy the condition given is:

$y= \frac{1}{4} x -28$
