How do I do this. Due tomorrow
kolbaska11 [484]
I prefer D.

It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
                 * 2      -> twice.
                 -1       -> 1 less.

So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.

How do we rewrite the equation y=-x 4
jek_recluse [69]
To rewrite as a function of x (f(x)), write the equation so that y is by itself on one side of the equal sign and an expression involving only x is on the other side.

f (x) = - x^4

Answer:

f(x) = -4x - 2

Step-by-step explanation:

To derive the function rule in slope-intercept form, f(x) = mx + b, we need to find the slope, m, and the y-intercept, b, of the graph given.

Using two points on the line, (-1, 2) and (0, -2), find slope (m) as shown below:

m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 2}{0 -(-1)} = \frac{-4}{1} = -4

m = -4

The line intercepts the y-axis at y = -2, therefore the y-intercept, b, = -2.

Substitute m = -4, and b = -2 into f(x) = mx + b.

The function rule in slope-intercept form would be:

f(x) = -4x +(-2)

f(x) = -4x - 2
