Answer:
x= -2 or 4
Step-by-step explanation:
|1-x|=3
1-x=3 or -(1-x)=3
x= -2 or 4
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 0) ← 2 points on the line
m = = -
Note the line crosses the y- axis at (0, 1) ⇒ c = 1
y = - x + 1 ← equation of line
Answer: the number of shoppers on the first day is 125
Step-by-step explanation:
The number of shoppers is 20% more than the numbers of shoppers the day before. It means that the number of shoppers is increasing in geometric progression. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
r = 1 + 20/100 = 1.2
n = 4(first 4 days)
S4 = 671
Therefore, the expression for the first 4 days is
671 = (a × 1.2^(4) - 1)/1.2 - 1
671 = (a × 1.2^(4) - 1)/0.2
671 = 1.0736a/0.2
671 = 5.368a
a = 671/5.368
a = 125
In a histogram, the highest bar is the mode, which means the number the bar represents appears the most.
The answer would be D. Three, because it appears most often.
