Answer:
see attached
Step-by-step explanation:
The point of intersection is found by equating the expressions for P:
6d = 5d +15
d = 15
p = 6d = 6·15 = 90
The point of intersection of the graphs is (15, 90).
The first equation graphs as a line with slope 6 through the origin.
The second equation graphs as a line with slope 5 through point (0, 15).
It is inconvenient to graph p and d using the same scale, so the attache graph has the vertical scale compressed somewhat.
Answer:
15°C
Step-by-step explanation:
Use the following formula to convert Fahrenheit to Celsius:

Substitute the value for the variable and solve for C.

Therefore, 59°F is equivalent to 15°C.
1) 6, 12,18,24
The rule used here is: Arithmetic Progression or Linear sequence
From the data above:
a = 6, d = 6

2) 3,6,9,12
The rule used here is: Arithmetic Progression or Linear sequence
From the data above:
a = 3, d = 3

3) 1,5,9,13
The rule used here is: Arithmetic Progression or Linear sequence
From the data above:
a = 1, d = 4

AC and AB are tangents to circle O, meaning that the angles C and B are right angles of 90 degrees. Since a quadrilateral's internal angles must sum up to 360 degrees, this means that A + B + C + O = 360
70 + 90 + 90 + O = 360
O = 110 degrees.
