Choose the linear inequality that describes each graph.
A. y ≥ 2x + 2
B. y ≥ – 2x + 2
C. y ≤ 2x – 2
D. y ≥ 2x – 2
Answer:
D. y ≥ 2x – 2
Step-by-step explanation:
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≥ 2 x + 2
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≥ − 2 x + 2
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≤ 2 x − 2
Graph the inequality by finding the boundary line, then shading the appropriate area.
y ≥ 2 x − 2

Henry wrote an ordered pair on an index card. (4, 8) The second number of any ordered pair indicates how far to travel in which direction a grid?
can someone solve this for me using pemdas
Answer:
24
Step-by-step explanation:
(25-10) ÷ 5 × 8
15 ÷ 5 × 8
3 × 8
24
Answer:
24
Step-by-step explanation:
Any work inside parentheses must be done first: (5^2 - 10). Also:
Exponentiation is done before addition/subtraction: 5^2 - 10 = 25 - 10 = 15
So now we have 15 / 5 * 2^3 and recognize exponentiation again:
15 / 5 * 8
Then, since multiplication and division have the same order of priority,
carry out the division in 15/5 and then multiply the result (3) by 8
to obtain 24 (final answer)
Which expressions are equivalent to 6x - 18 ?
c.) 3(2x-6)
Reason:-
3(2x-6) = 6x-18
Answer:
C, D, and E are your answers
3 x 2x = 6x, 3 x 6 = 18
6x - 18
x + 5x = 6x
6x - 18
2 x 3x = 6x
2 x 9 = 18
6x - 18

- i will give BRAINLIEST.
Answer:
B, C, D, and F are all possible.
Answer:
B, C, D
Step-by-step explanation:
1. A is not possible because right and obtuse both define triangle angles. An angle cannot be obtuse and right at the same time.
2. B is possible because a right triangle can have all sides of different length.
3. C is possible because a scalene triangle can have an obtuse angle.
4. D is possible because an isosceles triangle can have all acute angles.
5. E is not possible because of how equilateral triangles work. When a triangle is equilateral, it is also equiangular, meaning all of its angles are the same. The angles on every type of triangle always add up to 180 degrees. If a triangle is equiangular, the 180 degrees are divided evenly, with every angle being 60 degrees, which is acute. Therefore, an equilateral triangle cannot have a right angle.
6. F is not possible because isosceles and scalene both refer to the side lengths of triangles. A triangle cannot be isosceles and scalene at the same time.
7. G is not possible because equilateral triangles cannot have angles other than 60 degrees and therefore cannot be obtuse.

What is the area, in square centimeters, of the trapezoid below?
11.7 cm
5.5 cm
6.5 cm
Answer:
50.05 cm^2
Step-by-step explanation:
Ok so first lets find the area of the rectangle before finding the attached triangle. You have to imagine a line separating this shape into a triangle and rectangle.
The rectangle's size is 6.5x5.5=35.75 cm^2
The rectangle's size is 11.7-6.5 to get the base length, which is 5.2
The height is 5.5
So it's 5.2*5.5/2=14.3 cm^2
14.3+35.75=50.05 cm^2

Step-by-step explanation:
A cylindrical water tank of height 4 m is used to fill containers with dimensions 20 cm X 30 cm X 50 cm. If the tank can fill exactly 200 of these containers, find its base radius. (Take Pi = 3.14)
Answer:
0.35cm
Step-by-step explanation:
Step 1
We find the volume of the container.
The formula = Length × Width × Height
Length = 20cm
Width = 30cm
Height = 50cm
The volume of the tank = 20cm × 30cm × 50cm
= 30000 cm³
Step 2
We are told that:
The tank can fill exactly 200 of these containers
We have to find the volume that 1 cylinder will contain
Hence,
200 containers = 30000 cm³
1 container = x
Cross Multiply
200 × x = 30000cm³
x = 30000cm³/200
x = 150cm³
Step 3
We find the base radius of the cylindrical tank
Height = 4m
Convert to cm
1m = 100cm
4m = x
Cross Multiply
x = 4 × 100cm = 400cm
Volume of the cylinder = πr²h
Radius = √V/πh
Radius = √150/π × 400
Radius = 0.35 cm
Therefore, base radius = 0.35cm
Use the Pythagorean theorem to find the length of the line

This is one of my specialties so sit back, relax while I work on this for 5 mins :)
Step-by-step explanation:
The formula is a^2 + B^2 = c^2
Sooo
7^2 + 5^2 = c^2
49 + 25 = 74
√74 = √c^2
8.60232526 = c
8.60232526 rounded to the nearest tenth is 8.6
So there you go. Hope it helps!!
Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
• If a > 0 then vertex is minimum
• If a < 0 then vertex is maximum
Given
y = x² + 6x + 10
(a)
To complete the square
add/subtract ( half the coefficient of the x- term)² to x² + 6x
y = x² + 2(3)x + 9 - 9 + 10
y = (x + 3)² + 1 ← in vertex form
(b)
Since a = 1 > 0 then vertex is a minimum
(c)
(h, k ) = (- 3, 1 ) ← coordinates of vertex

Elizabeth buys 50 meters of ribbon to make bows for the cheer squad. Each bow uses 1.3 meters of ribbon. How many bows can Elizabeth make? *
Answer:
38 bows
Step-by-step explanation:
50 ÷ 1.3 ≡ 38 6/13
38 × 1.3 = 49.4
Since you cant make 6/13 of a ribbon, Elizabeth would be able to make 38 bows.

Answer:
x=30m
Step-by-step explanation:
Smaller triangle of sizes 26m and 10m...
using Pythagoras rule...let the middle line that so the triangle be y...
26² = 10²+y²
26²-10²=y²
y²=676-100
y²=576
y=√576
y=24m
the middle line is now 24m
now the larger triangle of sizes 18m, 24m and x...
using Pythagoras rule...
x²=24²+18²
x²=576+324
x²=900
x=√900
x=30m

Factor by gcf 6x2+3x+21 The 2 is supposed to be small.
Given:
The expression is:
[tex]6x^2+3x+21[/tex]
To find:
The factor of the given expression by GCF.
Solution:
We have,
[tex]6x^2+3x+21[/tex]
Here, 3 is the greatest common factor (GCF) of [tex]6x^2,3x,21[/tex].
Taking out GCF, we get
[tex]6x^2+3x+21=3(2x^2+x+7)[/tex]
Therefore, the required factor form of the given expression is [tex]3(2x^2+x+7)[/tex].
