How to solve system of equations?
Look at substitution and elimination as two methods for algebraically solving systems of linear equations.To better comprehend when systems of linear equations have one solution, no solutions, or infinitely many solutions, let's look at systems of linear equations graphically.Investigate algebraic techniques for counting the number of solutions to systems involving two linear equations.5x+y=-19 -- (i)
5x-4y=-24 ---(ii)
Subtract the above two equations:
5y = 5
y = 1
Substitute y=1 in equation (ii)
5x - 4(1) = -24
5x = -20
x = -4

-3x-4y=-1 3x-y=-4 elimination
Answer:
(- 1, 1 )
Step-by-step explanation:
- 3x - 4y = - 1 → (1)
3x - y = - 4 → (2)
add (1) and (2) term by term to eliminate x
0 - 5y = - 5
- 5y = - 5 ( divide both sides by - 5 )
y = 1
substitute y = 1 into either of the 2 equations and solve for x
substituting into (2)
3x - 1 = - 4 ( add 1 to both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
solution is (- 1, 1 )

Pls help i will mark brainliest Determine the value of y for the inequality 4 times the quantity y plus one fifth end quantity is less than or equal to four fifths.
y ≥ 0
y ≤ 0
y is greater than or equal to negative 1 over 40
y is less than or equal to negative 1 over 40
The value of y is less than or equal to 0 (y ≤ 0).
What is inequality?
In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.
Given:
4y + 1/5 ≤ 4/5
We have to find the value of y.
Subtract 1/5 from both sides,
4y + 1/5 - 1/5 ≤ 4/5 - 1/5
4y ≤ 3/5
Multiply both sides by 1/4
4y x 1/4 ≤ 3/5 x 1/4
y ≤ 3/20
y ≤ 0.15
Hence, the value of y is less than or equal to 0 (y ≤ 0).

If 5/33 is expressed in decimal form, what digit is in the 92nd place to the right of the decimal point?
Answer: 5
Step-by-step explanation:
If you plug 5/33 into a calculator (or just solve with long division), you'll find that it makes 0.151515... (with 15 repeating forever.)
In every EVEN decimal place there's a 5, but in every ODD decimal place there's a 1. (The first decimal place is 1, the second is 5, etc.)
Since 92 is an even number, there is a 5 in the 92nd decimal place.

Direct labor 2 hours $ 16.00 per hour $ 32.00
Fixed manufacturing overhead 2 hours $ 8.00 per hour $ 16.00
The company purchased 22,000 pounds of direct materials from its supplier at a cost of $12.50 per pound. The company used 22,000 pounds of direct material to start and complete 7,800 units of finished goods during the period. Its direct laborers worked 16,000 hours and were paid a total of $248,000. Based on this information, the total manufacturing cost transferred from Work in Process to Finished Goods would be:

There is no difference between the standard and actual expenses of direct labor because the company spent a total of $248,000 on such costs over the period.
How to calculate labor cost ?To determine the total increase recorded in the Work in Process account related to direct labor, we need to first calculate the total standard cost of direct labor for the period and then compare it to the actual cost of direct labor.
According to the standard cost card, each unit of the product requires 2 hours of direct labor at a rate of $16.00 per hour.
This means that the total standard cost of direct labor for the period is 2 * $16.00 * 7,800 = $248,000.
Since the company paid a total of $248,000 in direct labor costs during the period, there is no difference between the standard and actual costs of direct labor. Therefore, the total increase recorded in the Work in Process account related to direct labor would be $0.

What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
We know we can write y is inversely proportional to x as,
y ∝ 1/x.

To find the y intercept we need to let x=0
y=10*0+5=5 therefore y intercept =5
To find the x intercept we need to let y=0
we get 0=10x+5
We need to solve for x, this means getting x on its own
Take 5 from both sides

What is the maximum possible sum of the original four numbers?
The maximum amount of the original four numbers is 110.
What is the whole number?
A whole number is simply any positive number that does not include a fractional or decimal part. This means that, for example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers.
Four whole numbers are each rounded to the nearest 10, which means each number can go +5 or -5.
The sum of the rounded numbers is 90, the maximum amount of the original four numbers is if +5 are added with each 4 original number.
So each number would have an extra +5.
And then the maximum number is 90 + (5 x 4) is equal to 110.

If f(x) = log (x/4) and g(x) = 2 log x, find (g – f) (x).
Answer:
To find (g – f)(x), we need to subtract f(x) from g(x). We can do this by substituting the expressions for f(x) and g(x) into the difference:(g – f)(x) = g(x) – f(x)
= (2 log x) – (log (x/4))We can simplify this expression by using the fact that log a - log b = log (a/b). Applying this fact, we get:(g – f)(x) = (2 log x) – (log (x/4))
= log ((x^2) / (x/4))
= log (4x)Therefore, (g – f)(x) = log (4x).
Step-by-step explanation:
Step-by-step explanation:
To find (g – f)(x), we can subtract f(x) from g(x):
(g – f)(x) = g(x) – f(x)
= 2 log x – log (x/4)
Using the logarithm identity log a - log b = log (a/b), we can rewrite the expression as:
(g – f)(x) = log x^2 - log (x/4)
= log (x^2/(x/4))
= log (4x)
Therefore, (g – f)(x) = log (4x).

-15x + 20y = 15-5
0-18x + 24y - 18
Answer:
To solve this system of linear equations, we need to first rewrite the equations in standard form, which is the form y = mx + b. To do this, we can isolate the y-term on one side of the equation and the x-term and constant on the other side. For example, the first equation can be rewritten as follows:
-15x + 20y = 15-5
20y = 15 - 5 - 15x
y = -3/4 x + 2
Similarly, the second equation can be rewritten as follows:
0 - 18x + 24y - 18
24y = -18 - 18x
y = -3/2 x - 1
Now that the equations are in standard form, we can find the point of intersection by setting the two equations equal to each other and solving for x:
-3/4 x + 2 = -3/2 x - 1
-3/4 x + 2 + 3/2 x = -1 + 3/2 x
x = -1/6
Substituting this value of x into either equation, we can solve for y to find the point of intersection:
y = -3/4 x + 2
y = -3/4 (-1/6) + 2
y = 1/3
Therefore, the point of intersection for these two equations is (-1/6, 1/3). This means that the system of equations has exactly one solution at this point.

Opposite side is the side opposite angle θ
Adjacent side is the side next to the right angle and the angle θ
θ = Angle F
tan θ = 24/7
Angle F = tan⁻¹(24/7) = 73.7 (1 d.p.)
