1 answer:

6 0

1.) Function of x. $f (x) = \frac{4x}{9} -45$
Function of y. $f (y) = \frac{405}{4} + \frac{9y}{4}$
2.)Function of y. $f (y)= \frac{7}{2(y-48)}$
Function of x. $f (x) = \frac{7}{2x} + 48$

Answer:

The lines are perpendicular

Step-by-step explanation:

we know that

If two lines are parallel, then their slopes are the same

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

Remember that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Find the slope of the first line

we have the points

(-3,-1) and (1,-9)

substitute in the formula

$m_1=\frac{-9+1}{1+3}$

$m_1=\frac{-8}{4}$

$m_1=-2$

Find the slope of the second line

we have the points

(1,4) and (5,6)

substitute in the formula

$m_2=\frac{6-4}{5-1}$

$m_2=\frac{2}{4}$

Simplify

$m_2=\frac{1}{2}$

Compare the slopes

$m_1=-2$

$m_2=\frac{1}{2}$

Find out the product

$m_1*m_2=(-2)(\frac{1}{2})=-1$

therefore

The lines are perpendicular

To get 20% of something, you must divide it by 5 since 20*5=100
Anyway, since Jada's dog is 20% of it's adult weight, but currently weighing 9kg, we must multiply that by 5
9*5=45kg
Jada's dog's adult weight is 45kg
Hope it helped

There is a number that if you multiply it by 4 first, and then subtract 10 from the result, you get 14. What's the number.

It's 6. 6 times 4 is 24, and 24 minus 10 is 14
