The blue line has slope +1 and passes through the point (-3, 0). Using the point-slope formula, its equation would be
y - 0 = 1 (x - (-3))
or
y = x + 3
and so f(x) is defined by x + 3 for x ≤ 0.
The red line is horizontal for 0 < x < 3, so f(x) has a constant value of 1 for this interval. We use a strict inequality because the points (0, 1) and (3, 1) are unfilled circles.
The black (?) line has slope -1 and passes through (3, 0), so its equation is
y - 0 = -1 (x - 3)
or
y = -x + 3
so f(x) is defined by -x + 3 for x ≥ 3.
Putting everything together,
[tex]f(x) = \begin{cases}x+3&\text{if }x\le0\\1&\text{if }0<x<3\\-x+3&\text{if }x\ge3\end{cases}[/tex]

What happened to the comments?
Answer: I dont know what you mean by that.
Step-by-step explanation:
Face book comments can disappear for one of two reasons: the person who posted the comment on a post deleted it or the person who owns the original post deleted the comment because they didn't like it. From a business perspective, it may make sense to delete comments for many reasons.

Solve T = M(7 + FG) for F
F =
(Answer quickly)
Answer:
F = (T - 7M) ÷ MG
Step-by-step explanation:
T = M(7 + FG)
T = 7M + MFG
T - 7M = MFG
(T - 7M) ÷ MG = F
F = (T - 7M) ÷ MG
Answer:
Step-by-step explanation:
Remove the brackets
T = 7M + FGM Subtract 7M from both sides
T - 7M = FGM Divide both sides by GM
T - 7M
====== = F
GM
F = (T - 7M)/GM

A motorboat can maintain a constant speed of 45 miles per hour relative to the water. The boat makes a trip upstream to a certain point in 34 minutes; the return trip takes 26 minutes. What is the speed of the current?
The speed of the current is _ mile(s) per hour.
Answer: Distance upstream = (34-c)(39/60) miles
--------------------------
Distance downstream = (34+c)(29/60) miles
-----------------------------------------------
Equation:
distance = rate*time
distance up = distance down
(34-c)(39/60) = (34+c)(29/60)
Multiply both sides by 60 to get:
39(34-c) = 29(34+c)
39*34 - 39c = 29*34 + 29c
68c = 340
c = 5 mph (speed of the current)Step-by-step explanation: I'm not sure if this will help you but I hope it does!

Figure A was translated 1.5 inches right to create Figure B.
E.
Figure A was rotated
90
°
about a point in the middle of the figures to create Figure B.
Answer:
B
Step-by-step explanation:
Process of elimination, it wasn't reflected because point a and point E are on opposite sides in figure B compared to figure A. It wasn't rotated 90° Because point H is once again on the complete opposite side, if it was 90° it would be to the left or the right, not opposite. It wasn't translated Because all points are in different places.
Suppose Lisa places $6000 in an account that pays 18% interest compounded each year. Assume that no withdrawals are made from the account.
Follow the instructions below. Do not do any rounding.
(a) Find the amount in the account at the end of 1 year.
(b) Find the amount in the account at the end of 2 years.
Step-by-step explanation:
The formula for compounded interest is given by
[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]
where
A = amount of money after a time t
P = principal or initial amount of money
r = interest rate in decimal form
n = number of times money bnb is compounded per unit time
t = unit time
a) For this problem, P = $6000, n = 1 since the money is compounded once a year, t = 1 year and r = 0.18 so after one year, Lisa's money amounts to
[tex]A = (\$6000)\left(1 + \dfrac{0.18}{1}\right)= \$7,080[/tex]
b) After two years, the money is still compounded yearly so n = 1 but t = 2 years so Lisa's money amounts to
[tex]A = (\$6000)\left(1 + \dfrac{0.18}{1}\right)^{2} = \$8354.40[/tex]
Step-by-step explanation:
a)
Principal = $6000
Rate = 18%
Time = 1 year
A = P(1 + r/100)¹
A = 6000(1 + 18/100)
A = 6000(100 + 18/100)
A = 6000 × 118/100
A = 60 × 118
A = 7080
b)
Principal = $6000
Rate = 18%
Time = 2 years
A = P(1 + r/100)²
A = 6000(1 + 18/100)²
A = 6000(100 + 18/100)²
A = 6000(118/100)²
A = 6000 × 118/100 × 118/100
A = 6 × 118 × 118/10
A = 8354.4
Bernard left kumasi at 9:20 am He arrived in Takoradi at 5:49 How long did the journey take?
Answer:
8 hours and 29 minutes
Step-by-step explanation:
As he left at 9:20 am and the question said he arrived at 5:49, we must assume he came at pm. So next we just work out the difference between those times, which will leave you with that answer.

A 6-foot board is cut into two pieces. If one piece is x feet long, express the other length in terms of x.
Answer:
6 – x ft
Step-by-step explanation:
If a 6-foot board is cut in two pieces, both lengths could be anything that add up to 6 feet since the problem did not specify where the board was cut.
So if one piece is x feet long, the other must be 6 - x feet long because:
x + (6 – x) = 6
Write an equation in Slope-Intercept Form with a slope of 12 and passes through (−4,3).
Answer:
y = 12x + 51
Step-by-step explanation:
y = mx + b, where m is the slope and b is the y-intercept
The equation of line with a slop of m = 12
y = 12x + b
Since the point (-4,3) is on the line, it will satisfy the equation 3 = 12 (-4) +b
b = 3 - 12(-4)
b = 51
y = 12x + 51
