Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. x = 1.2 when y

= 3.

Y = k/x where k is the constant of variation
y = 3 , x = 1.2 gives
3 = k/1.2
therefore
k = 3*1.2 = 3.6
and the required equation is

y = 3.6 / x

How to do the fractions

GaryK [48]

First you make the mixed numbers/fractions into improper fractions. After that, you must find the common denominator, the LCM of 9 and 6 (for the 2nd problem). After that, if you can, simplify the fraction to lowest terms, which also includes making it a mixed number/fraction.

I hope this helps! :)

B) If the line is parallel, that means the slope is the same.
The slope for the original line is $\frac{-1-0}{6-2}$ = $\frac{-1}{4}$ .
The second form of coral line would be y = -1/4x + (any number). You could use y = -1/4x + 3.

c) Solve 12x = 24 + 3y for y.
3y = 12x - 24
y = 4x - 8
Perpendicular lines have negative reciprocal slopes... the negative reciprocal for -1/4 is 4. So yes, the third coral structure is perpendicular to the first coral.

F(x) = x^2. What is g(x)?

fredd [130]

Good evening ,

Answer:

B. g(x)= -x² - 4

___________________

Step-by-step explanation:

The graph of g is downward facing then we must have (-) before the x²

Since, The vertex of parabola g is on point (0 ,-4) then we have to subtract 4.
