I'll do the first two to get you started
===============================================
Problem 1
A = 3 = starting value
B = 10 = ending value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (10-3)/3 ] * 100%
C = (7/3) * 100%
C = 2.3333333 * 100%
C = 233.33333%
C = 233.3%
The positive C value means we have a percent increase. If C was negative, then we'd have a percent decrease.
<h3>Answer: 233.3% increase</h3>
===============================================
Problem 2
A = 9 = start value
B = 20 = end value
C = percent change
C = [ (B - A)/A ] * 100%
C = [ (20-9)/9 ] * 100%
C = (11/9)*100%
C = 1.2222222222*100%
C = 122.22222222%
C = 122.2%
<h3>Answer: 122.2% increase</h3>
Answer:
a)It is a vertical line with an undefined slope
b)It is a vertical line with an undefined slope
c)7/4
d)-7/4
Step-by-step explanation:
The formula for gradient of a line is given as;
m=Δy/Δx
where Δy = y₂-y₁ and Δx=x₂-x₁
<u>For L₁ </u>
x=2
It is a vertical line with an undefined slope
<u>For L₂</u>
x=-3
It is a vertical line with an undefined slope
<u>For L₃</u>
The points on the line are : (0,-3) and (4,4)
m= Δy/Δx
m= 4--3/4-0
m=7/4
<u>For L₄</u>
The points on the line are : (0,-3) and (-4,4)
m=Δy/Δx
m=4--3/-4-0
m=7/-4
m= - 7/4
