Answer:
x=−1 and y=−1
Step-by-step explanation:
Solve by substitution
x−y=0;2x+3y=−5
Step: Solve x−y=0 for x:
x−y+y=0+y(Add y to both sides)
x=y
Step: Substitute yfor x in 2x+3y=−5:
2x+3y=−5
2y+3y=−5
5y=−5(Simplify both sides of the equation)
5y/5=−5/5 (Divide both sides by 5)
y=−1
Step: Substitute−1 for y in x=y:
x=y
x=−1
Answer:
x=−1 and y=−1

What is a system of equations?A group of two or more equations that must be solved simultaneously make up a system of equations. There are many unknown variables in a system of equations, and each equation in the system depicts the relationship between those variables.
A set of variable values that satisfy every equation in a system of equations is the solution to the system of equations.
To solve this system of equations graphically, we can plot the two equations on a coordinate plane and find the point where they intersect, which represents the solution to the system.
a) To plot the equation x - y = 0, we can rearrange it to y = x and plot the line passing through the origin and the point (1, 1), as shown below:
Graph of the line y = x passing through the origin and the point (1, 1).
To plot the equation 2x + 3y = -5, we can rearrange it to y = (-2/3)x - 5/3 and plot the line passing through the points (-2, 1) and (1/3, -5/3), as shown below:
Graph of the line y = (-2/3)x - 5/3 passing through the points (-2, 1) and (1/3, -5/3).
b) The point where the two lines intersect is the solution to the system. From the graph, we can see that this point is approximately (-1.8, -1.8).
Therefore, the solution to the system is x = -1.8 and y = -1.8.

Answer:
CBD = 63 degrees
Step-by-step explanation:
To find CBD, we must first find the value of x. To do so, we use this equation since CBD and ABC equal 96 degrees:
(6x+27) + (7x-9) = 96
13x+18 = 96
13x+18-18 = 96-18
13x = 78
13x/13 = 78/13
x = 6
Now that we know the value of x, we factor it in to CBD to find its true value:
6x+27
6(6)+27
36+27
= 63 degrees
To check if this answer is correct, we can also find the value of ABC and see if the two values equal 96:
7x-9
7(6)-9
42-9
= 33 degrees
63 + 33 = 96
The answer is correct. CBD = 63 degrees and ABC = 33 degrees.

Answer:
[tex]\frac{5}{11}[/tex]
Step-by-step explanation:
30 regular flavors.
25 watermelon flavors.
Add them both and you get:
55.
Turn that into a fraction:
[tex]\frac{25}{55}[/tex]
The reason the numorator is 25 is because there are 25 watermelon flavors and 55 flavors total.
Find the GCD (or HCF) of numerator and denominator.
The GCD of 25 and 55 is 5.
Divide both the numerator and denominator by the GCD
25 ÷ 5 = 5
55 ÷ 5 = 11
Reduced fraction:
[tex]\frac{5}{11}[/tex]
Therefore, [tex]\frac{25}{55}[/tex] simplified to lowest terms is:
[tex]\frac{5}{11}[/tex]
Therefore, the answer is: [tex]\frac{5}{11} \\[/tex]

Answer:
parallelogram
explanation:
way to know if a quadrilateral is a parallelogram is if opposite sides are actually.
Answer:
I believe the answer is probably parallelogram because it is undetified if it is equivalent on the sides or not. If the sides were equal it would be an isosceles trapezoid and if they weren't it would be a trapezoid. Since there is not enough info about the side legnths of the figure it would more than likely be a parallelogram.

Identify the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector <−6, 3>.
Answers:
P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)
P ′(2, −8), L ′(7, −10), K ′(−3, 5)
P ′(−10, −8), L ′(−5, −10), K ′(−15, 5)
P ′(2, −2), L ′(7, −4), K ′(−3, 11)
Answer:
P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)
Step-by-step explanation:
The translation vector, ⟨−6,3⟩, can be used to derive a rule for the translation of the coordinates: (x,y)→(x−6,y+3).
Apply the rule to translate each of the three preimage vertices to the image vertices.
P(−4,−5)→P'(−10,−2)
L(1,−7)→L'(−5,−4)
K(−9,8)→K'(−15,11)
Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.
Answer:
P ′(−10, −2), L ′(−5, −4), K ′(−15, 11)
Step-by-step explanation:
P(−4,−5)→P'(−10,−2)
L(1,−7)→L'(−5,−4)
K(−9,8)→K'(−15,11)
Therefore, P'(−10,−2), L'(−5,−4), N'(−15,11) is the translation of the figure with the vertices P(−4,−5), L(1,−7), and K(−9,8), along the vector ⟨−6,3⟩.

A student randomly selects two buttons from a box containing 32 red buttons, 48 blue buttons, 44 green buttons, and 51
yellow buttons. Compute the probability, as a decimal ratio with four decimal places, of selecting two red buttons.
The probability of drawing two red buttons is:
P = 0.0326
How to get the probability?There are:
32 red buttons.48 blue buttons.44 green buttons.51 yellow buttons.So there are a total of 32 + 48 + 44 + 51 = 175
We assume that all the buttons have the same probability to being randomly drawn.
For the first button, the probability of drawing a red one is equal to the quotient between the number of red buttons and the total number of buttons:
p = 32/175
For the second button the probability is computed in the same way, but now there are 31 red buttons and 174 buttons in total, so we have:
q = 31/174
Finally, the joint probability is given by the product between p and q, this gives:
p*q = (32/175)*(31/174) = 0.0326

Answer:
finding the area:
146
Step-by-step explanation:
You need to break the image up into 3 pieces. the lower big triangle, the middle square, and the top triangle.
the measuremets of the lower big triangle is 14 and 14.
to find the area, we need to do 1/2 *14*14
this equals 98
The measurements of the square is 4,4.
we multiply 4*4 to get 16
The measurements of the top triangle is 8,8.
We find the area by doing 1/2*8*8
We get 32
lastly, we add up all of our solutions.
we do 98+16+32
we get 146.

For g(x) our (h,k) = (1,6)
h - translate right/left, our h = 1 is right 1.
h - translate up/dqwn, our k = 6 is up 6.
If a = positive - no reflect x-axis. If a = negative - reflect x-axis.
