Which graph represents -12x - 4y<-5
Where are the graphs?
please help me on this question!
Answer:
[tex]x=17.798[/tex]
Step-by-step explanation:
From the diagram given, [tex]x[/tex] is the opposite side of the angle. With this information, we can write:
[tex]sin(54^{\circ})=\frac{x}{22}[/tex] (SOHCAHTOA)
[tex]\frac{x}{22}[/tex] = [tex]0.809[/tex] (to the nearest hundredth)
[tex]x=0.809\times22[/tex]
[tex]=17.798[/tex]
∴ [tex]x=17.798[/tex]
Hope this helps :)

Maureen plants tulips in a rectangular flower bed that is 2 cubed feet wide and 2 Superscript 4 feet long. A rectangle with a length of 2 Superscript 4 feet and width of 2 cubed feet. What is the area of the flower bed? 48 square feet 128 square feet 4,096 square feet 16,384 square feet
Answer:
A = 128 square feet
Step-by-step explanation:
Given that,
Width of the flower bed, [tex]b=2^3\ ft[/tex]
Length of the flower bed, [tex]l=2^4\ ft[/tex]
We need to find the area of the flower bed. We know that the area of a rectangular shape is given by :
A = lb
Put values of l and b.
[tex]A=2^3\times 2^4\\\\=8\times 16\\\\=128\ ft^2[/tex]
Hence, the area of the flower bed is 128 square feet.

Answer:
x= 18
y =45
Step-by-step explanation:
first these two angles are supplementary and add up to 180 degrees:
(6x+7) + (4x-7) = 180
find x:
10x = 180
x = 18
substitute x = 18 for the angle (6x+7)
now we know what 6x +7 =
6 (18) + 7 = 115
since angle 3y-20 = 115, solve for y
3y = 135
y = 45
Answer:
x = 18
y = 45
Step-by-step explanation:
1. First off, we know that the angle (4x-7) degrees and (6x +7) are supplementary angles because of the corresponding angles theorem. So we do: (4x-7) + (6x+7) = 180 which should get you x=18.
2. Now that you know the value of x, finding y should be pretty easy. Plug in x for (6x + 7) and you should get 115 degrees.
3. We know that the angle with (6x +7) measurement is a vertical angle to (3y-20), so we can do 3y -20 = 115.
4. find the value of y, which should be 45
10(x + 4) – 3 = 14x + 1 infinitely many solutions no solution one solution
Answer:
This equation has one solution, where x is equal to nine.
Step-by-step explanation:
[tex]10(x + 4) - 3 = 14x + 1\\10x + 40 - 3 = 14x + 1\\14x - 10x = 40 - 3 - 1\\4x = 36\\x = 9[/tex]

You spend $132 on clothes. Shirts cost $12 and pants cost $16. You buy a total of 9 items. A. Write a system of linear equations that represents this situation. B. Solve the system and interpret your solution.
Answer:
a.
x+y=9 (1)
12x+16y=132 (2), where:
x is the number shirts
y is the number of pants
b. You bought 3 shirts and 6 pants.
Explanation:
The first equation would indicate that the number of shirts plus the number of pants is equal to 9:
x+y=9
The second equation would indicate that the price per shirt for the number of shirts plus the price per pant plus the number of pants is equal to 132:
12x+16y=132
The system of of linear equations that represents this situation is:
x+y=9 (1)
12x+16y=132 (2), where:
x is the number shirts
y is the number of pants
You can solve for x in (1):
x=9-y (3)
Then, you can replace (3) in (2):
12(9-y)+16y=132
108-12y+16y=132
4y=24
y=24/4
y=6
Now, you can replace the value of y in (3):
x=9-6
x=3

What are the rigid transformations that will map AABC to ADEF?
Answer:
A tranlation and a rotaion.
Step-by-step explanation:
In order to map the shapes, you have to translate point A onto point D and then rotate until points C and F, and B and E match up.
The rigid transformations that will map Δ ABC to Δ DEF is rotation then translation .
Single transformation maps ABC onto A'B'C' is reflection.
What is transformation of triangle?Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.

Write the equation of the line that passes through the points (2, -6) and
(6, -6). Put your answer in fully reduced point-slope form, unless it is a
vertical or horizontal line.
Answer:
The answer is
[tex]y + 6 = 0(x - 2)[/tex]
Step-by-step explanation:
We will need to find the slope.
[tex]m = \frac{ - 6 - ( - 6)}{6 - 2} = \frac{0}{4} = 0[/tex]
The formula of point-slope form is:
[tex]y - y_1 = m(x - x_1)[/tex]
Using the information we gathered and were given...
[tex]y + 6 = 0(x - 2)[/tex]

Answer:
Area of DEABC = 30100 m²
Step-by-step explanation:
Area of the given composite figure will be the sum of areas of 5 different figures.
Area of figure (1) = Area of right triangle ΔEGD
= [tex]\frac{1}{2}(EG)(GD)[/tex]
= [tex]\frac{1}{2}(120)(100+80)[/tex]
= [tex]60\times 180[/tex]
= 10800 m²
Area of figure (2) = Area right triangle AGE
= [tex]\frac{1}{2}(EG)(AG)[/tex]
= [tex]\frac{1}{2}(120)(30+50)[/tex]
= 60 × 80
= 4800 m²
Area of figure (3) = area of triangle AHB
= [tex]\frac{1}{2}(AH)(HB)[/tex]
= [tex]\frac{1}{2}(50)(50)[/tex]
= 1250 m²
Area of figure (4) = Area of trapezoid BCFH
= [tex]\frac{1}{2}(b_1+b_2)h[/tex]
= [tex]\frac{1}{2}(HB+FC)(HF)[/tex]
= [tex]\frac{1}{2}(50+100)(30+80)[/tex]
= [tex]\frac{1}{2}(150)(110)[/tex]
= 8250 m²
Area of figure (5) = Area of right ΔDFC
= [tex]\frac{1}{2}(DF)(FC)[/tex]
= [tex]\frac{1}{2}(100)(100)[/tex]
= 5000 m²
Therefore, area of composite figure = Area of (1) + Area of (2) + Area of (3) + Area of (4) + Area of (5)
= 10800 + 4800 + 1250 + 8250 + 5000
= 30100 m²

Answer:
19.55 square km
Step-by-step explanation:
Area of a circle is given by A = πr²
And area of it's sector is given by the formula,
A = [tex]\frac{\theta}{360}\times (\pi r^2)[/tex]
Here, r = Radius of the circle
θ = Angle at the center formed by the arc
Substituting values in the given formula,
Area = [tex]\frac{35}{360}\times \pi (8)^2[/tex]
= [tex]\frac{2240\pi}{360}[/tex]
= 19.547
≈ 19.55 square km
Therefore, area of the sector will be 19.55 square km.
