A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month.
kumpel [21]

Answer:

25

Step-by-step explanation:

Given that:

Initial payment done for buying the phone = $50

Charges per month for the phone = $25 per month

To find:

The equation to represent the situation and its slope.

Solution:

First of all, let us assume that m represents the number of months for which monthly is to be made.

Charges paid for one month = $25

Charges paid for m months =  $25m

Total cost of the phone = Initial payment + Charges paid for m months

C = 25m + 50

It is a linear equation between two variables C and m.

This equation can be compared with slope intercept form of a line.

Slope intercept form of a line is represented by:

y=Mx+c

M is the slope.

On Comparing, we get:

y = C, M = 25, x = m, c = 50

Therefore, the slope is <em>25</em>.

Given the equation f(x) = (x + 3)2 – 8, fill in the blanks:
Neko [114]
Quadratic f(x) = (x -h)² +k has vertex (h, k) and axis of symmetry x=h. When k is negative, the number of real solutions is 2, because both branches of the function cross the x-axis.

In your equation, h = -3 and k = -8.

Axis of symmetry: x = -3
Vertex: (-3, -8)
Number of real solutions: 2
