Answer: and
Step-by-step explanation:
First, we are told "sum of 5 times one number, x, and 4 times a second number, y, is 75":
(1)
Then, we are told "he sum of the two numbers is 18":
(2)
At this point we have our system of equations and now we are able to find the values of and
.
So, let's begin by isolating from (2):
(3)
Substituting (3) in (1):
(4)
Finding :
(5) This is the value of
Substituting (5) in (1):
(6)
Finding :

(8) This is the value of
Answer:
f(x) = 0.43 * *
*(x + 10)
Step-by-step explanation:
We have a 6th degree polynomial f(x)
r = 3 is a root of f with multiplicity 2
r = 1 is a root of f with multiplicity 3
f(-5) = -29721.6
f(-10) = 0
Then: f(x) = a*((x -3)^2 ) * ((x - 1)^3)*(x + 10)
f(-5) = a * (-8)^2 * (-6)^3 * (5) = -29,721.6
a* (64) * (-216)* 5 = -29,721.6
-a*69,120 = -29,721.6
a = -29,721.6/-69,120
a = 0.43
so
f(x) = 0.43 * *
*(x + 10)
The answers to the given questions are explained below as required:
Part A: Parallel lines are two lines that do not meet. So that the two lines are at an angle of to each other.
ii. A good example that contradicts the definition of parallel lines is the perpendicular lines. Two lines are said to be perpendicular if and only if they are at right angle to each other. Thus, the two lines would be at an angle of to one another.
iii. The definition that would be more accurate is: parallel lines are two lines that do not meet, even when extended till infinity.
Pat B: Undefined terms are terms that can be simply explained by descriptions. Some of the terms are: lines, rays, points etc.
ii. Lines can be used appropriately to illustrate parallel lines.
