what photo should i chose???
Answer:
Top right figure (the trapezoid)
Step-by-step explanation:
Line symmetry means that if you draw a line that cuts the figure, and reflect the figure across that line, the figure does not change.
Now, if we use vertical lines, a figure will have a line symmetry if it is exactly the same in the left as it is in the right.
And we can see that none of the figures meets this condition.
If instead, we use horizontal lines, then the figure must be equal above and below.
Particularly the "L" and the "t" can be discarded.
Also, the bottom right image can be discarded, as the bottom is clearly different than the top.
But the top right figure (the trapezoid) is exactly the same in the bottom as in the top, so if we reflect that image across a horizontal line that cuts it in two halves, the figure will not change, so that is the figure that has line symmetry,

2. Factorise completely the expression
2x² - 4x- 2xy+ 4y
Answer:
the first method is method of grouping so u say (2x - 4x) -(2xy+4y) so u already know that the 2x is square so no mean to put it there so u say 2x(x- 2)-2y (x+2) so u see the bracket are the same so u take one (x- 2) (2x -2y) done
Answer:
[tex]2(x-2) ( x-y)[/tex]
Step-by-step explanation:
Add and subtract the second term to the expression and factor by grouping.

5) m<EBF= 474
6)m<ABC= 70
5) 20x-10= x+390
5) 20x-10 3x+15+60=474
20x-10=390
3x+15= 24
plug in the x into the equation: (x+20)---> (20x20)=400
400-10= 390
6) 3x+1+2x+14= 28
3x= 9

A coin is tossed a number cube is rolled
P(tails and 3)
Answer:
1/6
Step-by-step explanation:
The coin toss and the cube roll are entirely separate and independent events. To find the joint probability P(tails and 3) we need only find the probabilities of the two events and then multiply them together.
P(tails) = 0.5
P(3) = 1/6, or 0.3333 ....
Desired joint probability = (1/2)(1/3) = 1/6

can someone please help with this and kinda explain this to me again please
Answer:
3rd Option;
x = 4
y = 116
Step-by-step explanation:
Let's start by solving for "x" first:
=> We know that in a parallelogram, opposite sides are parallel as well as congruent, therefore we can say:
Side 1 = It's opposite side
=> 16 = 3x + 4
=> 16 - 4 = 3x
=> 12 = 3x
=> 12/3 = x
=> 4 = x
Now that we know x, let's find the y-value;
=> We know that opposite angles in a parallelogram are congruent, therefore we can say;
Angle 1 = It's opposite angle
=> 56 = y - 60
=> 56 + 60 = y
=> 116 = y
Hope this helps!

Step-by-step explanation:
Which table of values can be represented by the function y = 3x + 2 ?
Answer:
Graph A.
Step-by-step explanation:
When x is equal to 0, why has to be equal to 2. The slope also has to be 3. To find this out, we do y2-y1/x2-x1. For A, the slope is -7--4/-3--2. This is equal to -3/-1. This is equal to 3. Because y=2 when x=0. option A is correct. For option D, when x=0, y=32. Therefore, this option is not correct. For option B, when x=0, y=2 so this could be correct. Plug it into y2-y1/x2-x1. This is equal to -1-0/-1-2. This is equal to -1/-3. 1/3 is not equal 3 so this option is not correct either. When x=0, y=32 for option C. Therefore, this option is not correct. Therefore, the answer is option A.
If this helps please mark as brainliest
Answer:
A
Step-by-step explanation:
for example
x = -4 and y = -10
y = 3x + 2
-10 = 3 . -4 + 2
-10 = -12 + 2
-10 = -10

Answer:
[tex]C\approx 5.14[/tex]
Step-by-step explanation:
The circumference is the distance around a complete circle: in essence, the perimeter of a circle. The formula to find the circumference of a circle is the following:
[tex]C=(d)(\pi)[/tex]
Where (d) represents the diameter, the largest cord that can be drawn in a circle, it goes from one end to another, passing through the center of the circle. The parameter ([tex]\pi[/tex]) represents the number (3.1415...). However, one is given a semicircle, thus one must divide the result in two, and then add the value of the diameter to find the perimeter of the given object. Therefore the equation for the circumference of this circle is as follows:
[tex]C=\frac{(d)(\pi)}{2}+(d)[/tex]
Substitute in the given value,
[tex]C=\frac{(2)(3.1415)}{2}+(2)[/tex]
Simplify,
[tex]C=3.1415...+2[/tex]
[tex]C=5.1415[/tex]
[tex]C\approx 5.14[/tex]

The measure of an angle is 97º. What is the measure of its supplementary angle?
[tex]{ \color{teal}{ \huge{ \textsf{ \textbf{Answer}}}}}[/tex]
We can calculate supplementary angles by subtracting the given one angle from 180 degrees. To find the other angle, use the following formula: ∠x = 180° – ∠y or ∠y = 180° – ∠x where ∠x or ∠y is the given angle.
The supplementary of 97° is (180°-97°)=83°
Julio solicitó un préstamo en el banco para invertir en su casa, pagó una cuota de $32,950 y otra de $25,825. Si el préstamo fue de $100.000. Cuánto dinero le debe al banco??
Answer:
Julio debe $ 41225 al banco por concepto del préstamo para invertir en su casa.
Step-by-step explanation:
Dada la falta de información, asumimos que el préstamo fue realizado sin tasa de interés, de modo que la deuda solo sea el monto inicial menos las cuotas pagadas por quien recibe el préstamo, la cantidad de dinero que adeuda al banco es:
[tex]x = \$\,100000 - \$\,32950 - \$\,25825[/tex]
[tex]x = \$ \,41225[/tex]

Change the mixed numerals into fractions.
= 35/3 × 21/5
Multiply the numerators together. Multiply the denominators together.
= (35 × 21)/(3 × 5)
Simplify.
= (7 × 5 × 7 × 3)/(3 × 5)
Divide the numerator and denominator by 3 and by 5.
= 7 × 7

The probability that one shopper, selected at random prefers either Beverage A or Beverage C; P(A or C) = 12/25.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
We are looking for the probability that one shopper, selected at random prefers either Beverage A or Beverage C.
a. A probability distribution of the experiment.
The probability of selecting Beverage A is ;
P(A) = 15/50 = 0.3
The probability of selecting Beverage B is ;
P(B) = 12/50 = 0.24
The probability of selecting Beverage C is ;
P(C) = 9/50 = 0.18
The probability of selecting Beverage D is ;
P(D) = 6/50 = 0.12
The probability of selecting Beverage E is ;
P(E) = 8/50 = 0.16
b. The probability that one shopper, selected at random prefers either Beverage A or Beverage C.
P(A or C) = 15/50 + 9/50
P(A or C) = 24/50
Thus, P(A or C) = 12/25

add 5 and 7 which get 12
i need some help plz
Answer:
x = 7
Step-by-step explanation:
*set equations = to each other since they're corresponding angles which are equal to each other*
15x - 5 = 13x + 9 --> *subtract 13x from both sides*
2x - 5 = 9 --> *add 5 to both sides*
2x = 14 *divde by 2 on both sides*
x = 7
check:
15 (7) - 5 = 13 (7) + 9
105 - 5 = 91 + 9

A science class has a ratio of 3 boys to 2 girls. Can there be 24 students in the class
Answer:
no
if you Let 3x be the number of boys
Let 2x be the number of girls
3x + 2x = 24
5x = 24
x = 4.8
3(4.8) = 14.4 boys
2(4.8) = 9.6 girls
There can't be 24 students for a ratio of 3 boys and 2 girls, because there can't be 14.4 boys and 9.6 girls, it has to be an exact number, otherwise it wouldn't make any sense
