What is the solution to the following system of equations?
x − 3y = 6
2x + 2y = 4
(-1, 3)
(3, -1)
(1, -3)
(-3, 1)
Answer:
The solution to the system of equations be:
[tex]x=3,\:y=-1[/tex]
Hece, option B is correct.
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}x-3y=6\\ 2x+2y=4\end{bmatrix}[/tex]
Multiply x − 3y = 6 by 2: 2x-6y=12
[tex]\begin{bmatrix}2x-6y=12\\ 2x+2y=4\end{bmatrix}[/tex]
so
[tex]2x+2y=4[/tex]
[tex]-[/tex]
[tex]\underline{2x-6y=12}[/tex]
[tex]8y=-8[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}2x-6y=12\\ 8y=-8\end{bmatrix}[/tex]
Solve 8y = -8 for y
[tex]8y=-8[/tex]
Divide both sides by 8
[tex]\frac{8y}{8}=\frac{-8}{8}[/tex]
[tex]y=-1[/tex]
[tex]\mathrm{For\:}2x-6y=12\mathrm{\:plug\:in\:}y=-1[/tex]
[tex]2x-6\left(-1\right)=12[/tex]
[tex]2x+6=12[/tex]
subtract 6 from both sides
[tex]2x+6-6=12-6[/tex]
[tex]2x=6[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{6}{2}[/tex]
[tex]x=3[/tex]
Therefore, the solution to the system of equations be:
[tex]x=3,\:y=-1[/tex]
Hence, option B is correct.
⚽ From Equation (i) we get :
x = 6 + 3y......[Equation (iii)]⚽ Now, Substitute the equation (iii) in equation (ii) we get :
→ 2(6 + 3y) + 2y = 4
→ 12 + 6y + 2y = 4
→ 8y = 4 - 12
→ 8y = -8
→ y = -8 ÷ 8
→ y = -1
⚽ Now Substituting value of y = -1 in equation (iii) we get :
→ x = 6 + 3y
→ x = 6 + 3(-1)
→ x = 6 + (-3)
→ x = 6 - 3
→ x = 3
Hence,the value of x = 3 and value of y = -1.20)

agenthammerx please help What is BPEMDAS
Answer:
BPEMDAS is the order of operations that every mathematician must follow.
General Formulas and Concepts:
Order of Operations: BPEMDAS
1. Brackets
2. Parenthesis
3. Exponents
4. Multiplication
5. Division
6. Addition
7. Subtraction
- Left to Right
Step-by-step explanation:
When we are given an evaluative expression, we must follow Order of Operations: BPEMDAS to evaluate the given expression. Here’s an example:
[2 + (4 / 2)] * 10
Evaluating this:
1. [Brackets] (Parenthesis) Divide: [2 + 2] * 10
2. [Brackets] Add: 4 * 10
3. Multiply: 40
Here we see that we use Order of Operations: BPEMDAS to evaluate a given expression.

Suppose you know that the volume of the following prism is represent by V(x) = -2x^3 + 14x^2 + 120x.
Step-by-step explanation:
-2x³ + 14x² + 120x
= -2x(x² - 7x - 60)
= -2x(x - 12)(x + 5).
The other 2 dimensions are -2x and (x + 5).
When using a graphing calculator to maximise the volume of the prism, we get x = 7.378. However this value is not reasonable as it makes -2x and (x - 12) negative, which are the sides of the prism.

3/7 to its decimal form and rounded to the nearest thousandth
Answer:
Decimal form: 0.4286
Step-by-step explanation:
The value of 3/7 in decimal form up to nearest thousands will be 0.4285.
A fraction 3/7 is given in the question.
We have to find it's decimal form and round-off it to nearest thousands.
What will be the value of 1/2 in decimal form rounded to units place ?
The value will be 0.5
To find the decimal form let's divide 3 by 7.
3 ÷ 7 = 0.428572
We have to round it to nearest thousands i.e., up to 4 places Right to decimal point.
The rounded value will be 0.4285.
thus , the decimal form of 3/7 will be 0.4285 rounded off to nearest thousands.

What is an equation of the line that passes through the points (1, 2) and (2, -1)?
Put your answer in fully reduced form.
Answer:
y = -x + 3
Step-by-step explanation:
The equation of a straight line is generally written as;
y = mx + b
where m is the slope and b is the intercept
To get the slope we use the slope formula
Mathematically, that is;
m = (y2-y1)/(x2-x1) = (-1-2)/2-1 = -3/1 = -1
To get the intercept we equate any of the points to the partial equation that we have;
From;
y = -x + b
2 = -1 + b
b = 1 + 2 = 3
So the equation is;
y = -x + 3

Answer:
One
Step-by-step explanation:
[tex] \frac{1}{2} (x +12) = 4x - 1 \\ \\ \frac{1}{2} x + \frac{1}{2} \times 12 = 4x - 1 \\ \\ \frac{1}{2} x + 6 = 4x - 1 \\ \\ 6 + 1 = 4x - \frac{1}{2} x \\ \\ 7 = \frac{8x - x}{2} \\ \\ 7 = \frac{7}{2} x \\ \\ 7 \times 2 = 7x \\ \\ x = \frac{7 \times 2}{7} \\ \\ x = 2[/tex]

A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 450 nails. The contractor bought twice as many large boxes as small boxes, which altogether had 4200 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.
Step-by-step explanation:
Let s represent the number of small boxes and l represent the number of large boxes.
We have 2s = l and 150s + 450l = 4200.
Therefore 150s + 450(2s) = 4200,
150s + 900s = 4200, 1050s = 4200, s = 4.
l = 2s = 2(4) = 8.
Hence there are 4 small boxes and 8 large boxes.
