Regardless of how the graph is oriented in the standard
(x,y) coordinate plane, NO graph in one of the
following categories has a vertical line of symmetry.
Which one?
F. Line
G. Square
H. Pentagon
J. Parallelogram
K. Scalene triangle
Answer:
the answer is j because it's impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other
Out of the given options, the shape that does not have a vertical line of symmetry is J. Parallelogram.
The correct answer is J. Parallelogram.
A vertical line of symmetry means that if a line is drawn vertically through the shape, the two halves will be mirror images of each other.
In the case of a line (F), it is one-dimensional and does not have an area, so it does not have any symmetry.
A square (G) has four sides of equal length and four right angles. It has both vertical and horizontal lines of symmetry, dividing it into four congruent quadrants.
A pentagon (H) is a five-sided polygon. Depending on its shape and orientation, it may or may not have a vertical line of symmetry. For example, a regular pentagon does have a vertical line of symmetry, while an irregular pentagon may not.
A parallelogram (J) is a four-sided polygon with opposite sides that are parallel and equal in length. It does not have a vertical line of symmetry because its opposite sides are not mirror images of each other.
A scalene triangle (K) is a triangle with no equal sides or equal angles. It does not have a vertical line of symmetry because its sides and angles are not symmetric.

A triangle has a base of 8 cm and a height of 12 cm.
What is the area of the triangle?
Enter your answer in the box.
*box* cm2
Answer: 48 cm^2
Step-by-step explanation:
The equation for the area of a triangle is 1/2(base*height). Plug in the numbers to get an equation of 1/2(8*12). 8*12 = 96. Now divide by 2. 96/2 = 48.
Answer:
48 cm^2
Step-by-step explanation:
a triangle area is hb/2
so 8*12=96
96/2=48 therefore 48 is the answer.
Solve the system of equation using ELIMINATION (solve for x)
x + 3y = 14
-x + y = 10
Answer:
x = -1.5 , y = 5.17
Step-by-step explanation:
Solve the system of equation using ELIMINATION (solve for x)
x + 3y = 14
-x + y = 10
Solution
x + 3y = 14 ------- equation 1 * 1
-x + y = 10 ------- equation 2 * 3
x + 3y = 14 ------- equation 3
-(-3x + 3y = 30)------ equation 4
Using the ELIMINATION METHOD.
x-(-3x) + 3y-3y = 14-30
4x = -6
x = [tex]\frac{-6}{4}[/tex]
x = -1.5
Substuting -1.5 into equation one
x + 3y = 14
-1.5 + 3y = 14
Adding 1.5 to both sides
-1.5 + 1.5 +3y = 14 +1.5
+3y = 15.5
Dividing by the coeffient of y
[tex]\frac{3y}{3} = \frac{15.5}{3}[/tex]
y = 5.166666666666
y =5.17
Therefore x = -1.5 , y = 5.17

£1 = ∈1.46
To convert from euros to pounds, divide the euros by 1.46
To convert from pounds to euros, multiply the pounds by 1.46
Question 21
14.60 euros = 14.60 ÷ 1.46 = £10
Question 22
109.50 euros = 109.50 ÷ 1.46 = £75

the bill at an electronics store was $52 before tax.
tax is 5 percent. what is the total price with tax?
Answer:
$54.6
Step-by-step explanation:
To solve the question, we need to find how much 5% of 52 is
For questions where we need to calculate the percentage, we will multiply the number by given percentage and then divide it by the whole, 100%
52*5/100 = 2.6
Now the price before the tax was 52 and the tax is 2.6
the total price:
2.6 + 52 = 54.6
Jeff has a balance of $2,513.77 on his credit card. He would like to pay off his card over the course of a year and a half by making identical monthly payments. The APR on his card is 10.66%, compounded monthly. Assuming that Jeff makes no additional purchases with his card, how much will he have to pay every month to reach his goal? (Round all dollar values to the nearest cent.) a. $151.73 b. $162.57 c. $139.65 d. $147.64 Please select the best answer from the choices provided A B C D
Using the monthly payment formula, it is found that the amount he will have to pay is given as follows:
a. $151.73.
What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
In which:
P is the initial amount.r is the interest rate.n is the number of payments.In this problem, the parameters are given as follows:
P = 2513.77, r = 0.1066, n = 1.5 x 12 = 18.
Hence:
r/12 = 0.1066/12 = 0.008883.
[tex]A = 2513.77\frac{0.008883(1 + 0.008883)^{18}}{(1 + 0.008883)^{18} - 1} = 151.73[/tex]

Using the equation, y=5x²−17x −12, determine the y-intercept.
A) (0, -12)
B) (4, 0)
C) (1.7, -26.4)
D ) (0, 12)
Answer:
A
Step-by-step explanation:
to find the y- intercept let x = 0 in the equation and solve for y
y = 5(0)² - 17(0) - 12 = 5(0) - 0 - 12 = 0 - 12 = - 12
then the y- intercept is (0, - 12 )
Answer:
[tex]\huge\boxed{\sf (0,-12)}[/tex]
Step-by-step explanation:
Given equation:[tex]y=5x^2-17x-12[/tex]
y-intercept is the point where x = 0
Put x = 0 in the above equation.
[tex]y=5(0)^2-17(0)-12\\\\y = 0-0-12\\\\y=-12[/tex]
So, y = -12, when x = 0.

Answer:
15) A
Step-by-step explanation:
4x-2 + 7x + 17 = 180
11x + 15 = 180
11x = 165
x = 15
Because the two angles (4x-2 and 7x+17) are linear, we can say that they add up to 180 degrees.
4x-2+7x+17 = 180 Now, simplify like terms
11x + 15 = 180
11x = 165
x = 15
Thus, the value of x would be 15 (choice 1)

Find the volume of a cone with the base of 10 and height of 6
Answer:
Answer = 157
Step-by-step explanation:
The formula to finding the volume of a cone is h(pi)(r^2)/3. We know that the height is 6 and the base is 10. This means that the radius is 5 because it is 1/2 of the base. Now we plug in our numbers into the equation and get 157!
