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 
represents the number of months for which monthly is to be made.
Charges paid for one month = $25
Charges paid for months = $25
Total cost of the phone = Initial payment + Charges paid for months
It is a linear equation between two variables 
and .
This equation can be compared with slope intercept form of a line.
Slope intercept form of a line is represented by:
is the slope.
On Comparing, we get:
Therefore, the slope is <em>25</em>.
Answer:
10 degrees
Step-by-step explanation:
1.) every triangle has angles that add up to 180 degrees
2.) a right triangle has a right angle and two acute angles
3.) right=90 degrees; acute=<90 degrees
4.) 90+80=170
5.) 180-170=10
Answer:
The value of t is 41
Step-by-step explanation:
<em>The figure is 5 sided polygon.</em>
The sum of interior angles of 'n' sided polygon is given by,
= 
here, n=5,
thus, 
All the given angles have linear pair in the polygon.
Thus, t = 41
Answer:
Step-by-step explanation:
Part A
9x^2 + 24x + 16
= (3x + 4)(3x + 4)
length of each side = 3x + 4 units.
Par B
16x^2 - 25y^2
= (4x + 5y )( 4x - 5y)
length = 4x + 5y and width = 4x - 5y
