Graph the system of linear inequalities on the coordinate plane.
Shade the solution to the system of inequalities.
Pick a point and show your solution is correct.
Answers
The graph can be seen at the end, and by looking at it, you can see that a solution can be (10, 0).
How to graph the system of inequalities?
y ≥ (-1/2)*x + 2 + 1/2
y < (1/5)*x + 6
To graph it, first we need to graph the lines:
y = (-1/2)*x + 2 + 1/2
y = (1/5)*x + 6
Once you have this, we analyze each inequality.
y ≥ (-1/2)*x + 2 + 1/2
Because we use the symbol ≥ we need to use a solid line and we need to shade the region above the line.
For y < (1/5)*x + 6 we need to use a dashed line (the symbol < implies that the points on the line are not solutions) and we need to shade the region below the line.
Then the solution of the system is given by the intersection of the shaded region.
For example, a solution can be the point (10, 0), which you can see that belongs to that region.

Solve... 4x + 30 = -6(x - 2)
I got -4.2 but it's wrong!
Answers
Answer: x= -9/5 or x = -1.8
Step-by-step explanation:
4x + 30 = -6(x - 2) First apply the distributive property on the left side
4x + 30 = -6x + 12 Add 6x to both sides
+6x +6x
10x + 30 = 12 Subtract 30 from both sides
-30 -30
10x = -18 Divide both sides by 10
x = -9/5 or x = -1.8
Answer:
the answer is -1.8 if you want to use the decimal and -9/5 if you want to use the fraction
Step-by-step explanation:
4x + 30 = -6(x - 2)
4x+30 = -6x + 12
4x + 6x = 12 - 30
10x = -18
divide both side by 10
x = -9/5 or -1 4/5 or -1.8

Given B(17,5), C(11, -3), D-1, 2), and
E(x, -6), find the value of x so that BC || DE.
Answers
Answer:
[tex]x=-7[/tex]
Step-by-step explanation:
Remember that:
Two lines are parallel if their slopes are the same.Two lines are perpendicular if their slopes are negative reciprocals.And two lines are neither (a.k.a intersecting) if they are neither parallel nor perpendicular.We want to find the value of x such that [tex]\overline{BC}\parallel\overline{DE}[/tex].
Therefore, the slopes of BC and DE must be equivalent.
So, let's find the slope of BC first.
BC)
We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let B(17, 5) be (x₁, y₁) and let C(11, -3) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{-3-5}{11-17}[/tex]
Subtract:
[tex]m=-8/-6=4/3[/tex]
So, the slope of BC is 4/3.
DE)
Let D(-1, 2) be (x₁, y₁) and let E(x, -6) be (x, y₂). Substitute:
[tex]\displaystyle m=\frac{-6-2}{x-(-1)}[/tex]
We know that the two slopes must be equal. So, the slope of DE must also be 4/3. Substitute 4/3 for m:
[tex]\displaystyle \frac{4}{3}=\frac{-6-2}{x-(-1)}[/tex]
Solve for x. Simplify the right:
[tex]\displaystyle \frac{4}{3}=\frac{-8}{x+1}[/tex]
Cross multiply:
[tex]4(x+1)=-8(3)[/tex]
Multiply on the right:
[tex]4(x+1)=-24[/tex]
Divide both sides by 4:
[tex]x+1=-6[/tex]
Subtract 1 from both sides:
[tex]x=-7[/tex]
So, the value of x is -7.
And we're done!

Width - 27 ft: length - 61 ft
Width - 44 ft: length - 102 ft
Answers
Answer:
width- 22ft : length-51 ft
Step-by-step explanation:
if you add 22+22 its 44 +7 it will give you 51.
that is twice the width+ the 7 feet
The dimensions of the room will be 22 feet and 51 feet. Then the correct option is A.
What is the perimeter of the rectangle?The sum of all the sides of the rectangle will be known as the perimeter of the rectangle. Let L be the length and W be the width of the rectangle.
Then the perimeter of the rectangle will be
Perimeter of the rectangle = 2(L + W) units
The length of a rectangular room is 7 feet longer than twice the width. Then we have
L = 2W + 7
If the room's perimeter is 146 feet. Then the dimension of the rectangle will be
P = 2(L + W)
146 = 2(2W + 7 + W)
73 = 3W + 7
3W = 66
W = 22 feet
Then the length of the rectangle will be
L = 2 x 22 + 7
L = 44 + 7
L = 51 feet
The dimensions of the room will be 22 feet and 51 feet. Then the correct option is A.

Kristen has been waiting all summer for her family's annual road trip. This year, they're headed to Yellowstone National Park. Kristen just saw a sign that said the park is 10 miles away, so the drive is almost over. If Kristen's father drives 50 miles per hour, how many more minutes will it take to reach the park?
Answers
Answer: It will take 12 minutes to the reach the park.
Step-by-step explanation:
We know that, [tex]\text{Speed }=\dfrac{\text{distance}}{\text{time}}[/tex]
[tex]\Rightarrow\ \text{Time}=\dfrac{\text{Distance}}{ \text{Speed}}[/tex]
Given: Speed = 50 miles per hour
Distance needs to travel = 10 miles
Now, Time required to reach the park = [tex]\dfrac{10}{50}=\dfrac{1}{5}\text{ hour}[/tex]
Since 1 hour = 60 minutes
So, [tex]\dfrac15\text{ hour}=\dfrac15\times 60=12\text{ minutes}[/tex]
Hence, it will take 12 minutes to the reach the park.

Tamara wants to calculate the height of a tree outside her home. Using her clinometer, she measures the angle from 35 feet away from the base of the tree and gets an angle of 62°. Tamara's eye level is 5.5 feet above the ground. How tall is the tree?
Answers
Answer:
71.32 feet
Step-by-step explanation:
We set up a trigonometric function to get height of tree
Distance ,x = 35 feet away from tree base
Angle = 62⁰ at eye level
Y = tan(angle) * x
= Y = tan(62⁰) x 35
Y = 1.881 x 35
Y = 65.82 feet
We add Tamara's height to the total height of the tree
= 65.82feet + 5.5 feet
= 71.32 feet is the height of the tree

The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled. The total capacity of the water tank is gallons, and the rate of change is gallons per hour.
Answers
Answer:
Total capacity of the water tank is 400 gallons
Rate of change in water level is 20 gallons per hour
Step-by-step explanation:
The graph attached represents the gallons of water in a water tank with respect to the number of hours since it was completely filled.
The total capacity of the water tank is represented by the y-intercept of the graph that is 400 gallons.
Now to calculate the rate of change in water level we will take two points on the given line and find the slope.
There are two points (0, 400) and (5, 300) on the line.
So the slope of the line is (400-300)/(0-5)= -100/5= -20
This minus notation of slope shows that level of water is reducing and rate of change in water level is 20 gallons per hour.

C: 5/11
Step-by-step explanation:
The top line over the numbers usually mean the numbers are recurring (occurring again and again)
So 0.45 with the dash over the 45 means 0.454545454545... (goes forever, hence why we use the dash)
To solve you convert each option to a decimal and find one that has 0.45 recurring.
A: 4/5 =0.8
B: 5/9 = 0.55...
C: 5/11 = 0.45...
D: 4/9 = 0.44...
Hence, our answer is C.
Answer: It means that the numbers the bar is over repeats. Answer is C
Step-by-step explanation:
For example:
Example 1: [tex]0.123 \overline {4}[/tex] → The bar is only over the number 4 so only the number 4 repeats. [tex]0.123 \overline {4} = 0.123444444444444444444444...[/tex] with the number 4 repeating forever.
Example 2: [tex]0.12 \overline {34}[/tex] → This time the bar is over the 3 and the 4, so 34 and 4 repeat. [tex]0.12 \overline {34} = 0.12343434343434...[/tex]
Example 3: [tex]0.1 \overline {234}[/tex] = 0.1234234234234234234...
Example 4: [tex]0. \overline {1234}[/tex] = 0.123412341234123412341234...\
To solve your problem, it will be easiest to use a calculator and test each answer.
Choice A: [tex]\frac{4}{5} = .8 \neq . \overline{45}[/tex]
Choice B: [tex]\frac{5}{9} = 0.55555556 \neq 0. \overline{45}[/tex]
Choice C: [tex]\frac{5}{11} = 0.454545454545... = 0. \overline {45}[/tex]
Choice D: [tex]\frac{4}{9} = .44444444444... = 0. \overline {4} \neq 0. \overline {45}[/tex]
