The information for two pay as you go cell phone companies is given

1 answer:

5 0

One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).

Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.

The unit rate is 2,86:2,50

Rewriting standard form to slope intercept

algol [13]

If you're asking how, here's an example

A standard form equation is when it is set up.

Ax + By = C.

6x + 2y = 4.

A slope-intercept form equation is when it is set up y=mx+b.

Y = - 3x + 2.

4y = -8x + 16 then divide all by 4.

y = -2x + 4 slope form.

Answer:

D. Minimum at (3, 7)

Step-by-step explanation:

We can add and subtract the square of half the x-coefficient:

y = x^2 -6x +(-6/2)^2 +16 -(-6/2)^2

y = (x -3)^2 +7 . . . . . simplify to vertex form

Comparing this to the vertex for for vertex (h, k) ...

y = (x -h)^2 +k

We find the vertex to be ...

(3, 7) . . . . vertex

The coefficient of x^2 is positive (+1), so the parabola opens upward and the vertex is a minimum.
