Answer:

x: -5,  -3,   0,  1,  4

y:-23, -15, -3, 1, 13        for the function.

x:-23, -15, -3, 1, 13

y: -5,   -3,  0,  1,  4         for the inverse.

Step-by-step explanation:

we know that if we have the function f(x) = y, then the inverse of f(x) (let's call it g(x)) is such that:

g(y) = x.

now we have

y=4x-3

y=(1/4)x+3/4

The only table that works for our first function is:

x: -5,  -3,   0,  1,  4

y:-23, -15, -3, 1, 13

You can see this by replacing the values of x and see if the value of y also coincides.

Then, using the fact that the other table must be for the inverse, we should se a table with the same values, but where the values of x and y are interchanged.

The second table is that one:

x:-23, -15, -3, 1, 13

y: -5,   -3,  0,  1,  4

Write the equation of the line that is perpendicular to the line 8y−16=5x through the point (5,-5).
disa [49]

Answer:

y = -(8/5)x + 3

Step-by-step explanation:

Step 1:  Rewrite the given equation into slope-intercept form by solving for y

8y−16=5x

 

   8y = 5x + 16

 

      y = (5/8)x + 2

Perpendicular lines have slopes that are opposite reciprocals of each other.  That means you take the slope, flip the fraction, and change the sign.

Here our given line is y = (5/8)x + 2 so the slope 5/8

The opposite reciprocal of 5/8 is -8/5

We set up the equation

y = -(8/5)x + b      

  we are given a point (x, y) of (5, -5), so plug that in and solve for b

-5 = -(8/5)(5) + b

    -5 = -8 + b

     3 = b  

So our equations is  y = -(8/5)x + 3

Fruit:sugar in a ratio 2:3 if 8kg of fruit is used, how much sugar?
Vilka [71]
Hey there.

Considering our ratio from fruit to sugar is 2:3, this means we need to make a proportion. I will set this up below;

2:3 = 8:x; x is a variable substitute for our missing sugar value. Let's try to see if 2 divides into 8.
8 / 2 = 4; this means our scale factor of our ratio is 4x larger than the current value, so multiply 2 and 3 by 4 to solve for sugar.

2:3;

2 x 4 = 8; 8:x
3 x 4 = 12; 8:12.

12kg is the missing sugar value in our proportion; therefore, 12kg of sugar is used when 8kg of fruit is used.

I hope this helps!
