b. (4,2)
Step-by-step explanation:
step one: isolate x in the first equation
substitute x=6-y: [tex]\begin{bmatrix}2\left(6-y\right)-2y=4\end{bmatrix}[/tex]
[tex]\begin{bmatrix}12-4y=4\end{bmatrix}[/tex]
[tex]-4y=-8[/tex]
[tex]y=2[/tex]
step two: isolate y in the second equation, substitute y=2
[tex]x=6-y[/tex]
[tex]x=6-2[/tex]
[tex]x=4[/tex]
Answer:
b
Step-by-step explanation:
Given the 2 equations
3x + 3y = 18 → (2)
2x - 2y = 4 → (2)
Multiplying (1) by 2 and (2) by 3 and adding the result will eliminate the y- term
6x + 6y = 36 → (3)
6x - 6y = 12 → (4)
Add (3) and (4) term by term to eliminate y
12x + 0 = 48
12x = 48 ( divide both sides by 12 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
3(4) + 3y = 18
12 + 3y = 18 ( subtract 12 from both sides )
3y = 6 ( divide both sides by 3 )
y = 2
solution is (4, 2 ) → b

Find the coordinates of the point for the reflection.
(-8,5) across the x-axis
Answers
Answer:
(-8, -5)
Step-by-step explanation:
If (-8, 5) is reflected across the x-axis, the x-coordinate stays the same (-8), but the y coordinate becomes -5. Hence the coordinates of the reflection are (-8, -5).
If point (-8, 5) is reflected across the x axis, the new point is (-8, -5)
What is transformation?
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
If point (-8, 5) is reflected across the x axis, the new point is (-8, -5)

Answers
Answer:
x= -1
Step-by-step explanation:
since y is -5 then we would put that in the second equation:
2x - 4(-5) = 18
then it’s:
2x + 20 = 18
Then we subtract 20 from both sides
2x = -2
Last we divide both by 2 and we get x = -1
Answer:
x= -1
Step-by-step explanation:
2x + 20 =18
2x = 18 - 20
x = -1

what’s the perimeter?
The perimeter of a triangle Park shown on the rate is 13 X -7 what is the missing length
Answers
Answer:
The length of the missing side is 7x-5
Step-by-step explanation:
Here, we want to get the value of the missing length
Mathematically, the perimeter of a triangle can be obtained by adding the lengths of its sides
So by subtracting the sum of the lengths of the two given sides from that of the perimeter, we get the length of the third side of the triangle
mathematically, we have this as;
13x-7 -(4x + 2 + 2x-4)
13x-7 - (4x + 2x + 2-4)
= 13x-7 - (6x -2)
= 13x -7 -6x + 2
= 13x-6x -7 + 2
= 7x -5

Complete question :
Stacy has a spinner (1 - 4) and a number cube (1 - 6) after spinning and rolling the number cube she will add two number what is the probability that the sum of the numbers from the spinner and number cube will be 3 or 4
Answer:
5 /24
Step-by-step explanation:
The sample space for the sun of the outcome of the spinner and rolled number cube ;
Sample space = total possible outcomes = 6 * 4 = 24
Required outcome = sum equals 3 or 4 = 5
P(obtaining a sum of 3 or 4) = required outcome / Total possible outcomes
P(obtaining a sum of 3 or 4) = 5 /24

Each bag of rice has a mass of 1.2 kg.
In kilograms, what's the mass of each bag of flour?
Answers
The mass of each bag of flour is 2 kg.
What is mass?In physics, mass is a quantitative measure of inertia, which is a fundamental property of all matter. In the International System of Units, a kilogram is a unit of mass (SI).
How to solve this problem?Given that the mass of each bag of rice is 1.2 kg. We can see that there are 5 and 3 bags containing rice and flour respectively. First, we have to calculate the total weight of the right side of the weight machine. Then we equate it with the total weight of the left side of the weight machine.
Let, the mass of each bag of flour be y kg.
Now,
Weight of the right side = Weight of the left side
i.e. number of rice bags × mass of rice bags = no. of flour bags × mass of flour bags
i.e. 5 × 1.2 = 3 × y
i.e. 3y = 6.0
i.e. y =6/3=2
So, the mass of each bag of flour is 2 kg.

You can represent the measures of an angle and its complement as x° and (90 - x)°. Similarly, you can represent the measures of and angle and is supplement as x° and (180 - x)°. Use these expressions to find the measure of the angles described. The measure of the supplement of an angle is three times the measure of its complement. The measure of the angle is________ degrees, the measure of its complement is degrees, and the measure of its supplement is ________degrees.
Answers
Answer:
The angle is equal to 45°, its complementary is equal to (90-45)°=45°, and its supplementar is equal to (180-45)°=135°
Step-by-step explanation:
Let the angle be equal to x°. We know that
[tex](180 - x) = 3(90- x)[/tex]
Therefore, solving for x, we have
[tex]180 - x = 270 - 3x \\ 2x = 90 \\ x = 45[/tex]
So the angle is equal to 45°, its complementary is equal to (90-45)°=45°, and its supplementar is equal to (180-45)°=135°
