Answer:
trapezoids.
Step-by-step explanation:
rectangles will always have symmetry because they have 90-degree angles and can't be irregular. squares are rectangles so they also have symmetry. Rhombi by definition have two pairs of identical angles, so they must be symmetrical.
Trapezoids have angled sides, which don't have to be the same, therefore, trapezoids makes the statement false

how do you illustrate quadratic equation in one varible?
Answer:
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.

Determine if (2, 3) is a solution to the following equation
y = 5x - 1
Answer:
No, it is not
Step-by-step explanation:
You have to plug it in:
(x,y) = (2,3)
y=5x-1 is also 3=5(2)-1
3=10-1
3=9 is a false statement so it is not a solution.
Why are the solutions to the proportions StartFraction 50 over x EndFraction = StartFraction 10 over 20 EndFraction and StartFraction 10 over 50 EndFraction = StartFraction 20 over x EndFraction the same? because both result in the equation 20 x = 500, which simplifies to x = 25 because both result in the equation 20 x = 500, which simplifies to x = 250 because both result in the equation 10 x = 1,000, which simplifies to x = 10 because both result in the equation 10 x = 1,000, which simplifies to x = 100
Given:
Two equations are
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
To find:
The reason for same solutions to the proportions.
Solution:
First equation is
[tex]\dfrac{50}{x}=\dfrac{10}{20}[/tex]
On cross multiplication, we get
[tex]50\times 20=10\times x[/tex]
[tex]1000=10x[/tex]
Divide both sides by 10.
[tex]\dfrac{1000}{10}=x[/tex]
[tex]100=x[/tex]
The second equation is
[tex]\dfrac{10}{50}=\dfrac{20}{x}[/tex]
On cross multiplication, we get
[tex]10\times x=50\times 20[/tex]
[tex]10x=1000[/tex]
Divide both sides by 10.
[tex]x=\dfrac{1000}{10}[/tex]
[tex]x=100[/tex]
Solutions to the proportions are same because both result in the equation 10 x = 1,000, which simplifies to x = 100.
Therefore, the correct option is D.

Point A ( 5, 3) is reflected across the x-axis what is the coordinate of the image.
Answer:
(5, -3)
Step-by-step explanation:
when you reflect across x axis the y changes symbols.
The Point A(5, 3) is reflected across the x-axis, then the coordinate of the image is (5, -3).
What is a reflection?A reflection is a type of transformation that involves flipping a shape, known as the preimage, over a line, known as the line of reflection, to produce a new shape (called the image). You can picture what would happen if you flipped the form over the line in order to graph a reflection.
Given:
The point A(5, 3) is reflected across the x-axis.
The reflection across the x-axis:
The rule for a reflection over the x-axis is,
(x, y) → (x, −y).
So, the image point,
(5, 3) → (5, −3)
Therefore, the image point is (5, −3).

Answer: 127 degrees
Step-by-step explanation:

E F
H G
I had to write it out the parallelogram so I could have a better visual.
F and G are consecutive angles in a parallelogram (not on opposite sides).
This means they add to be 180 degrees.
F+G=180
(3x-10)+(5x+22)=180
(3x+5x)+(-10+22)=180
8x +12=180
Subtract 12 on both sides:
8x =180-12
Simplify:
8x =168
Divide both sides by 8:
x =168/8
x =21
If x=21 and want the measurement of angle G, then
(5x+22)=(5*21+22)=127.
So angle G has measurement 127 degrees.
The the measure of angle G will be 127°. Then the correct option is D.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.
In parallelogram, the sum of the two adjacent angle is 180 degrees.
In parallelogram EFGH, the measure of angle F is (3x − 10)° and the measure of angle G is (5x + 22)°.
The angle F and angle G are the adjacent angle.
The sum of angle F and angle G is 180°.
∠F + ∠G = 180°
3x - 10 + 5x + 22 = 180
8x = 168
x = 21
Then the the measure of angle G will be
∠G = (5x + 22)°
∠G = (5 × 21 + 22)°
∠G = (105 + 22)°
∠G = 127°
The the measure of angle G will be 127°.
Then the correct option is D.

Answer:
see explanation
Step-by-step explanation:
Given a point (x, y ) then its distance from the origin is
d = [tex]\sqrt{x^2+y^2}[/tex]
(a) (2, 3 ) , then
d = [tex]\sqrt{2^2+3^2}[/tex]
= [tex]\sqrt{4 + 9}[/tex]
= [tex]\sqrt{13}[/tex] ≈ 3.6 units ( to 1 dec. place )
------------------------------------------------
(b) ( - 5, 7 ) , then
d = [tex]\sqrt{(-5)^2+7^2}[/tex]
= [tex]\sqrt{25+49}[/tex]
= [tex]\sqrt{74}[/tex] ≈ 8.6 units ( to 1 dec. place )
-------------------------------------------------
(c) (- 1, 4 )
d = [tex]\sqrt{(-1)^2+4^2}[/tex]

How many times greater is the value of 0.02 than the value of 0.002
The value of 0.02 is 10 times greater than the value of 0.002.
What is meant by inequality?If two given numbers are not equal, we use inequality. It means that the first number is either greater than or less than the second number.
we have a value of 0.02 greater than the value of 0.002
[tex]\frac{2}{100} = \frac{2}{1000} \\[/tex]

Sonya is a waitress. She earns $200 per week plus a 15% tip on the cost of each meal she serves. What must be the total cost of the meals she serves in order for her to earn at least $425 each week?
help me please
Answer:
Sonya would need to serve 1500 meals
Step-by-step explanation:
425=15%(x)+200 or 425=.15(x)+200
solve for x
425=.15x+200 distribute
subtract 200 from both sides
225=.15x
divide both sides by .15 to isolate x
1500=x or x=1500
