Answer:
x = - 10
Step-by-step explanation:
2(x + 3) = x - 4 ← distribute parenthesis on left side
2x + 6 = x - 4 ( subtract x from both sides )
x + 6 = - 4 ( subtract 6 from both sides )
x = - 10
Answer:
-10
Step-by-step explanation:
2(x+3)=x-4
2x+6=x-4
2x-x=(-4)-6
x=-10
Hence the answer is -10

2. Factor out the greatest common factor (GCF): Factoring out the greatest common factor from each of the terms in the equation.
3. Use the distributive property: Rewriting an expression using the distributive property to make it easier to solve.
4. Combine like terms: Summing or subtraction the same terms on both sides of the equation.
5. Use factoring techniques: Factoring a polynomial equation to make it easier to solve.
6. Use the addition or subtraction principle: Rewriting an equation so that all the terms are on the same side of the equation.
7. Use the multiplication or division principle: Rewriting an equation so that all the terms are on the same side of the equation, multiplied or divided by the same number.
8. Use substitution: Replacing an unknown with a known value in an equation.
9. Use the quadratic equation: Solving an equation with a quadratic equation if it can be written in the form of ax2 + bx + c = 0 by simplify.

The linear function that has a slope of -4 and goes to point (9,-10) will be y = -4x - 50.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
Suppose that the linear function is y = mx + c

By means of the law of cosine, the missing side of the triangle has a length of approximately 6.502 units.
How to use the law of cosine in a triangle
Herein we find the case of a triangle with two known side lengths and a known measure of an angle between the two given sides. The measure of the unknown side is determined by the law of cosine, whose definition is shown below:
x² = a² + b² - 2 · a · b · cos θ
If we know that a = 15, b = 12 and θ = 25°, then the equation for the triangle is:
x² = 12² + 15² - 2 · 12 · 15 · cos 25°
Now we proceed to simplify and find the resulting value of x by algebra properties:
x² = 369 - 360 · cos 25°
x² = 369 - 326.271
x² = 42.279
x ≈ 6.502

a bag contains 40 pieces of candy, of which 36 are mint and 4 strawberry flavor. if the pieces of candy are distributed in a random manner to four children so that each child receives 10 pieces, what is the probability that all four strawberry pieces will be received by the same child?
The probability that all four strawberry pieces will be received by the same child 9/10 outcome.
Total piece of candy = 40
Mint flavor = 36
Strawberry = 04
There are 36 + 04 = 40 total outcomes for the chocolate pick.
There are 36 outcomes resulting in you picking a mint candy.
Probability is the number of outcomes you’re testing for divided by the number of total outcomes. So in this case that’s 36/40 or 4/5 . And also,
04 /40 = 1/10
Therefore, adding both, we get,

Hill co. Can further process product o to produce product p. Product o is currently selling for $60 per pound and costs $42 per pound to produce. Product p would sell for $82 per pound and would require an additional cost of $13 per pound to produce.
The Hill Co. should not further produce Product P from Product P.
We need to calculate the incremental cost and incremental revenue of producing P to understand the profit or loss margin.
Incremental revenue = Selling product of P - Selling product of O
Incremental revenue = 82 - 60
Performing subtraction
Incremental revenue = $22
Incremental cost = Cost of producing O - Cost of producing P
Incremental cost = 42 - 13
Performing subtraction
Incremental cost = $29
It is clear that incremental cost is more than incremental revenue, so Hill Co. should not continue the production.
