Given that h(x) = 3x −19, find the value of x that makes h(x) = 71.
rosijanka [135]

Keywords:

<em>Equation, variable, value, clear </em>

For this case we have an equation with a variable of the form y = h (x). Where h (x) = 3x-19. Given the value ofh (x) = 71, we want to find the value of the variable "x". So, we have:

h (x) = 3x-19\\71 = 3x-19

We must clear "x", for this, we add "19" to both sides of the equation:

71 + 19 = 3x-19 + 19\\90 = 3x

We divide between "3" on both sides of the equation:

\frac {90} {3} = \frac {3x} {3}\\30 = x

Thus, the value of the variable "x" is 30.

Answer:

x = 30

Option A

Suppose that y varies directly with x and y =10 when x = 20. What is y when x=15
Vanyuwa [196]

y=13.34 when x=15

Step-by-step explanation:

We are given that x varies directly with y i.e y ∝ x

We know that: y ∝ x then

y= k/x

where k is constant.

So, if y=10 and x=20 we can find k

y=\frac{k}{x}\\10=\frac{k}{20}\\ k=10*20\\k=200

Now, we need to find y when x=15

We know that k = 200,

So, y=\frac{k}{x}\\y=\frac{200}{15}\\y=13.34\\

So, y=13.34 when x=15

If f(x)=-3x+3, then f^-1 (x)=____<br> Please help
fgiga [73]

Answer:

y = (-x/3) +1   or y = (-1/3 * x) + 1

Step-by-step explanation:

For the inverse of a function, you invert the y and x positions.

In your case:

y = -3x+3

The inverted function is:

x = -3y+3

When you solve this for y, you get:

-3y = x-3

y = -x/3 +1
