How do you solve this, I can't seem to comprehend this, its hard for me. ;
The solution to the system of equation is the point where both lines intersect and it is at (3, 0)
System of equations
Given the following system of equations
x + y = 3
- 2x + y = -6
Graphically, the point where both lines intersect on the place is the solution to the given system of equation.
From equation 1, x = 3 - y
Substitute into equation 2:
- 2(3-y) + y = -6
-6 + 2y + y = -6
3y = -6 + 6
y = 0
Substitute y = 0 into any of the equation
x + y = 3
x + 0 = 3
x = 3
Hence the solution to the given system of equation is (3, 0)

What are increasing and decreasing functions?Calculus functions called increasing and decreasing functions have f(x) values that change according to how much x rises or decreases. The behavior of growing and decreasing functions is examined using the derivative of the function f(x). If the value of f(x) grows as the value of x increases, the function is said to be increasing; conversely, if the value of f(x) decreases as the value of x increases, the function is said to be declining.
Like wise in this question we just have to find the d/dx and if it comes out positive then the function is increasing and if it is negative then it is decreasing.

Determine how much greater the average rate of change over the interval [ 7, 9] than the interval [4, 6].
Given:
Step 1
Calculate the average rate of change over the interval [ 7, 9] using the formula below:
[tex]Rate\text{ of change=}\frac{f(b)-f(a)}{b-a}[/tex]a= 7 f(a)=1852
b=9 f(b)=3878
Substitute the values into the formula and simplify.
[tex]Average\text{ rate of change=}\frac{3878-1852}{9-7}[/tex][tex]=\frac{2026}{2}=1013[/tex]Step 2
Calculate the average rate of change over the interval [4, 6] using the same formula in step 2.
a=4 f(a)=358
b=6 f(b)=1178
[tex]average\text{ rate of change=}\frac{1178-358}{6-4}[/tex][tex]=\frac{820}{2}=410[/tex]Step 3
Compare the average rate of change over the two intervals.
Clearly, the average rate of change over the the interval [7, 9] is greater than the average rate of change over the interval [4, 6].

Rewrite the following in the form log (c) log(4) + log(3)
The required logarithm in the form log(c) is log(12).
What are logarithms?The inverse function to exponentiation in mathematics is called the logarithm. If aˣ = n, then x is the logarithm of n to the base a, which is expressed mathematically as x = logₐ n.
Given:
log(4) + log(3)
Using the product property of logarithms, which states that a product's logarithm is equal to the sum of its logarithms.
log(ab) = log a + log b
Here, a = 4 and b = 3
So, log(12) = log(4) + log(3)

Here are three different recipes for Orangey-Pineapple Juice. Two of these mixtures taste the same and one tastes different.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice.
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice.
Which two recipes will taste the same, and which one will taste different? Explain or show your reasoning.
Using ratio we can conclude that Recipe 1 and recipe 2 tastes the same.
The multiplicity of two integers is shown by a ratio. For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.
An ordered pair of integers, a fraction with the first number in the numerator and the second in the denominator, or the value represented by this fraction are all ways to conceptualize ratios. Rational numbers, and occasionally natural numbers as well, are ratios of counts stated in terms of (non-zero) natural numbers. When two numbers are compared using the same unit of measurement, which frequently occurs, their ratio is a dimensionless number. A rate is created by multiplying two amounts with different unit measurements.Let us consider the ratio of the orange juice top the pineapple juice for the 3 recipes.
Recipe 1 = 4 : 6 = 2 : 3
Recipe 2 = 6 : 9 = 2 : 3
Recipe 3 = 9 : 12 = 3 : 4
Hence from the above ratios we can conclude that Recipe 1 and recipe 2 tastes the same.

Suppose that country A and country B initially have the same per capita GDP. After that, country A grows at 3.5 percent per year and country B grows at 7 percent per year. According to the rule of 70, after 40 years what is the ratio of country B's GDP to country A's?
Using the Rule of 70, it is found that after 40 years, the ratio of country B's GDP to country A's is of 2.
What is the Rule of 70?The rule of 70 is a rule that is used to determine how long it takes for an amount to double, dividing 70 by the variable's growth rate, as a percentage.
Country A grows at 3.5 percent per year, hence the time it takes to double is:
70/3.5 = 20 years.
Hence in 40 years, it's GDP will be of:
4n, in which n is the current GDP, and 4 because it will have doubled twice.
Country B grows at 7 percent per year, hence the time it takes to double is:
70/7 = 10 years.
Hence in 40 years, it's GDP will be of:
8n, in which n is the current GDP, and 8 because it will have doubled three times.
Then the ratio of country B's GDP to country A's will be of:

Find the final price of each item television: $375.00 discount: 25% tax: 6%
PLEASE HELP MEEEEEEEE!!!
I really need to understand how to work out this problem and solve it!
Thank You!
The final price of the television is $299.53.
Discount is somewhat a reduction in the actual or usual price of the object or service. Whereas, tax is the money that we have to pay to the government.
Price of television before discount = $375.00 (given)
Discount given = 25% (given)
25% of $375 is,
$375* (25/100)= $93.75.
The cost of the television after sale off and before the sales tax is:
$375- $93.75= $281.25
The sales tax = 6% (given)
$281.25* (6.5/100)= $18.28
The price of the television including everything is,
$281.25+ $18.28= $299.53
Therefore, we can conclude the the final price of television is $299.53.

Factories produce a total of 21550 gallons in a calendar year.
The gallon is used as a unit of volume in both imperial and US customary measurements.
Eight pints make up a gallon, which is a unit of measurement for liquids. It is equivalent to roughly 4.546 litres in Britain. It is roughly equivalent to 3.785 litres in America.
Lemonade, it has been stated, equals 11,650 gallons.
Lemonade = 4,950 fewer than ice tea.
Ice tea: 3,500 fewer than Root beer.
Using the formula Ice tea = 11,650 - 4,950
6700 gallons of iced tea
Root beer = 6700 - 3,500
3200 gallons equals root beer.
Total manufacturing output for a year is equal to 11,650 + 6700 + 3200
