m = 4, p = 4
Note that when two variables are placed directly next to each other, you are multiplying
plug in 4 for both m and p
(4)(4) + 4
Multiply
4 x 4 = 16
Add
16 + 4 = 20
20 is your answer
hope this helps
Answer (Note: the bold are answers):
First question answer:
Point = (3,1)
Slope = 3
y = 3x + b
(1) = 3(3) + b
1 = 9 + b
1 - 9 = b
-8 = b
y = 3x - 8
The second question answer:
y = mx + b
Get two points:
(3,-7) and (4,-11)
m = -11 - (-7) / 4 - 3
m = -11 + 7 / 1
m = -4 / 1
m = -4
b = + 3
y = -4x + 3
5 : 5, 10, 15, 20, 25
6 : 6, 12, 18, 24, 30
Answer:

Option (C) is correct .
Step-by-step explanation:
As the expression given in the question as follows.

Now rationalize the expression.

Using the formula
a² - b² = (a - b) (a + b)
Using in the above


As i² = -1



Option (C) is correct .
