The graph that matches the given linear inequality is (B) .
In the question ,
it is given that
the linear inequality is y [tex]>[/tex] -x + 4
on rewriting the inequality
we get
x + y [tex]>[/tex] 4
to plot the inequality , we need points to plot .
So ,when x = 0 , we have y = 4
and when y = 0 , we have x = 4
so the two points are (0,4) and (4,0) .
For shading the inequality , we put x = 0 and y = 0 ,
and get 0+0 > 4
0>4 , the result is False , So , the shaded region will be away from the origin which is shown in option (b) .
Therefore , The graph that matches the given linear inequality is (B) .

A graden plot 4m by 12m has one side along the fence.The area of the garden is to be doubled by digging a border of uniform width on the other three sides.What should the width of the border be?
Answers
The width of the border is 6 m after digging a border of uniform width on the other three sides.
Step 1:
Original garden plot is 4 m by 12 m. The 12 m side is against the wall.
A border of length D is along three sides of the plot (the 4th side is the wall).
Step 2
area of original garden plot is 12 x 4 = 48 [tex]m^{2}[/tex]
area of new plot = 96 [tex]m^{2}[/tex] (twice the original plot)
96 = (4 + D) (12 + 2D)
Set up equation for the area of the new area of the new plot (double the area of the old garden plot).
Step 3
96 = (4 + D) (12 + 2D)
[tex]96 = 2d^{2}+12d+4(2d+12)[/tex]
[tex]96 = 2d^{2}+12d+8d+48[/tex]
[tex]96 = 2d^{2}+20d+48[/tex]
[tex]96 -2d^2-20d-48 = 0[/tex]
[tex]48-2d^2-20d = 0[/tex]
[tex]-2(d^2+10d-24) = 0[/tex]
d = -12
Now solve for D
Step 4
D = 6 meters
Ignore negative answer because border must be a positive number. So Border is -12 [tex]m^{2}[/tex] (6 m).
Hence the answer is the width of the border is 6 m after digging a border of uniform width on the other three sides.

Sel 9.5.37 Assigned Media Question Help D You, a A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 17 feet more than the length of the shortest side. Find the dimensions if the perimeter is 153 feet. What is the length of the shortest side?
Answers
First we can set the equations we already know
[tex]a\text{ +b +c = 153 ft}[/tex]Where a, b and c are the sides of the triangle. Then, I will assign "a" the shortes side. One side is twice the shortest side so:
[tex]b\text{ = 2a }[/tex]Now, the sentence says, the third side is 17 feet longer that the shortes side "a":
[tex]c\text{ = a + 17}[/tex]Now we have a system of three equations with three unknown variables, so it will be easy to find the value of all the variables. If we put "b" and "c" in the first equation we have:
[tex]a\text{ + (2a) + (a+17) = 153 ft}[/tex][tex]\begin{gathered} 4a\text{ = 153-17} \\ 4a\text{ = }136 \\ a\text{ = 136/4} \\ a=34 \end{gathered}[/tex]Now, since we assigned "a" as the shortest side, we are done.

What is the equation of the line that passes through the point (-3,-6) and has a slope of 1/3
Answers
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
How can I locate a slope?You may determine the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two points. The increase divided by the run is the slope.The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) expressions of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively.Formula m = rise / run = y2 - y1 / x2 - x1m = slope

The slope is [tex]\frac{3}{4}[/tex]
What is slope ?
A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane can aid in determining whether the line is parallel, perpendicular, or not. Any two clearly separated points on a line can be used to calculate the slope of any line. Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined.
here the given two pints are
[tex](x_1,y_1)=(-2,4)\\(x_2,y_2)=(6,10)[/tex]
Now using slope formula,
slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
=> slope m = [tex]\frac{10-4}{6+2}[/tex]

It Carlos sits 3 feet from the fulcrum of a see-saw, how far from the fulcrum must his baby-sister who weighs three-times his weight sit?
A. 1 foot
B. 6 feet
C. 3 feet
D. 9 feet
Answers
Answer: B: 6 feet
Step-by-step explanation: To solve this problem, we need to use the concept of leverage, which is the force applied to an object at a distance from its pivot point. In this case, Carlos is applying a force of 3 feet from the fulcrum, while his baby sister is applying a force 3 times as large, at a distance from the fulcrum.
To find the distance from the fulcrum that the baby sister must sit, we need to balance the forces applied by Carlos and his sister. This means that the product of the force applied by Carlos and the distance from the fulcrum must be equal to the product of the force applied by his sister and the distance from the fulcrum where she must sit.
We can use this information to write the equation: 3 * 3 = 3 * x
Where x is the distance from the fulcrum where the baby sister must sit. We can solve for x by dividing both sides of the equation by 3 to get: x = 6
Therefore, the baby sister must sit 6 feet from the fulcrum in order to balance the forces applied by Carlos and his sister. The correct answer is B. 6 feet.

Yesterday jack drove 38 1/2 miles. He used 1 1/4 gallons of gasoline. What is the unit rate for mile per gallon
Answers
Answer:
the unit rate for miles per gallons is 32.4 miles per gallon
Step-by-step explanation:
From the information we have, Jack drove 401/2 miles and used a total of 1 1/4 gallons of gasoline.
We need to find out how many miles he travelled per each gallon.
40 1/2 miles can be written as 40.5 miles
1 1/4 gallons can be written as 1.25 gallons.
So now we form an equation.
40.5 = 1.25
x = 1
Where x is the number of miles per gallon
We cross multiply the equation
40.5 * 1 = 1.25 * x
40.5 = 1.25x
40.5 / 1.25 = x
32.4 = x
x = 32 .4

where
θ is the central angle
r is the radius of the circle

By substituting these values into the formula,
