describe and find the slope of the line
A rectangular schoolyard is to be fenced in using the wall of the school for one side and 500 meters of fencing for the other three sides. The area in square meters of the schoolyard is a function of the length in meters of each of the sides perpendicular to the school wall.
A. Write an expression for A(x) using NO SPACES.
B. What is the area of the schoolyard when x = 100 ?
C. What is a reasonable domain for x in this context?
Answer:
StPart 1) The expression is
Part 2) The area of the schoolyard when x=40 m is A=2,800 m^2
Part 3) The domain is all real numbers greater than zero and less than 75 meters
Step-by-step explanation:
Part 1) Write an expression for A(x)
Let
x -----> the length of the rectangular schoolyard
y ---> the width of the rectangular schoolyard
we know that
The perimeter of the fencing (using the wall of the school for one side) is
so
-----> equation A
The area of the rectangular schoolyard is
---> equation B
substitute equation A in equation B
Convert to function notation
Part 2) What is the area of the schoolyard when x=40?
For x=40 m
substitute in the expression of Part 1) and solve for A
Part 3) What is a reasonable domain for A(x) in this context
we know that
A represent the area of the rectangular schoolyard
x represent the length of of the rectangular schoolyard
we have
This is a vertical parabola open downward
The vertex is a maximum
The x-coordinate of the vertex represent the length for the maximum area
The y-coordinate of the vertex represent the maximum area
The vertex is the point (37.5, 2812.5)
using a graphing tool, see the attached figure
therefore
The maximum area is 2,812.5 m^2
The x-intercepts are x=0 m and x=75 m
The domain for A is the interval -----> (0, 75)
All real numbers greater than zero and less than 75 meters

B=(s+k/2)h solve for s
Answer:
B = (s + k/2)h
[flip if wanted]
h(s + k/2) = B
h*s h*k
h/s + g/2 = B
g/2 = P
h/s + P = B
-P -P
h/s*h [<-cancel out] B*h
J = s

Write an equation of the line that is perpendicular to y=-3x+1 and passes through point (5,3).
Answer: There are two formulas that we will use the first one is the y=m x+b and the second one is finding the perpendicular line.
Step-by-step explanation:
the first one is
y=m x+b
y= 3 x -12
the second one is
first find the negative reciprocal of the slope of the original line and use the point slope formula y- y,= m(x - x1) to find the line perpendicular to
Y= 3 x 1
X= 5
what is 9,340 x 4/3.
Answer:
12453.3333333
Step-by-step explanation:
4/3 is the same things as 4 ÷ 3 which is 1.33333333333
1.33333333333*9340 = 12453.3333333
Hope this helps!
Which of the following best describes the slope of the line below?
O A. Zero
B. Negative
C. Positive
D Undefined
Answer:
B
Step-by-step explanation:
going down on the right
Answer:
B
Step-by-step explanation:
Aline with zero slope is a horizontal line parallel to the x- axis
A line with undefined slope is a vertical line parallel to the y- axis
A line sloping upwards from left to right has a positive slope
A line sloping downwards from left to right has a negative slope.
The line shown slopes downwards from left to right and has a negative slope

Is 65/126 about 1/4?
Answer:
No
Step-by-step explanation:
65/126 = 0.5158730..
1/4=0.25
The 65/126 (0.5) is not less than the 1/4 (0.25) which means that the given statement 1/4 is More than 65/126

1. What the error was
2. How can U check ur answer
Answer:
The first one: the error was that the 3 shouldn’t have been moved but the 5 should have. The correct answer is k=-8
The second one: the error was that they added the 6 and 4, you would only get -10 if the 4 was - the correct answer is -2
You can check your answer by plugging in your answer to the variable and making sure both side equal each other
Step-by-step explanation:
The first one: the 5 should be - from both side so you get k=-8
The second one: the 4 should be + to both sides. And the -6 and +4 should be added together to get n=-2
Remember you always want to get the variables by themselves.

fraction in lowest terms 33 1/3
Answer:
If you are asking for its improper fraction form then it is 100/3
Step-by-step explanation:
33*3 (3 is the denominator) = 99
1/3 + 99/3 = 100/3
You can not divide 100 by 3 (and get a whole number), and therefore it can not be simplified anymore and is the lowest possible term for fractions.
Ex. 2/4 can be simplified to 1/2 but 3/4 can not be simplified anymore.
Another example:
12 1/4
12*4 = 48
1/4 + 48/4 = 49/44

Solve each compound inequality -10-2v<6and6v+12<-6
Answer:
v>-8 ; v<−3
Step-by-step explanation:
−10−2v<6
Step 1: Simplify both sides of the inequality.
−2v−10<6
Step 2: Add 10 to both sides.
−2v−10+10<6+10
−2v<16
Step 3: Divide both sides by -2.
−2v/−2 < 16/−2
v>−8
6v+12<−6
Step 1: Subtract 12 from both sides.
6v+12−12<−6−12
6v<−18
Step 2: Divide both sides by 6.
6v

<
−18

v<−3
The first picture I sent ( the one which is from -8 to 14) is for −10−2v<6 and the second one (that has -3 to -9) is for 6v+12<−6
