The given equation is non-linear.
Solution:
Given expression is [tex]\frac{3}{x} +\frac{4}{y} =2[/tex].
To find the equation is linear or non-linear.
Linear equation is a straight line which is in the form ax + by + c = 0.
Otherwise it is non-linear equation.
⇒ [tex]\frac{3}{x} +\frac{4}{y} =2[/tex]
Do cross multiply for the fractions to make the denominators same.
⇒ [tex]\frac{3y}{yx} +\frac{4x}{yx} =2[/tex]
⇒ [tex]\frac{3y+4x}{yx} =2[/tex]
Do cross multiplication.
⇒ [tex]3y+4x=2yx[/tex]
⇒ [tex]4x+3y-2yx=0[/tex]
Here, there is no constant term.
So, the equation is not a straight line.
Hence, the given equation is non-linear.
Which expression is equivalent to (−2)x + (−6)x?
A) −8x
B) −4x
C) 4x
D) 8x
Which ordered pair is a solution of the equation? y=7x-2
Answer:
(1, 5 )
Step-by-step explanation:
To obtain a solution, substitute any value for x into the equation and solve for y, that is
x = 1 → y = 7(1) - 2 = 7 - 2 = 5 → (1, 5 )
x = - 1 → y = 7(- 1) - 2 = - 7 - 2 = - 9 → (- 1, - 9 ) is also a solution
Name two number that are not integers but that are opposite. Explain how you know
Answer:
Decimals, fractions and mixed units are not integers.
Step-by-step explanation:
Final answer:
Opposite non-integer numbers are pairs like 1/2 and -1/2 or 3.5 and -3.5. These pairs are not integers due to their fractional parts, yet they add up to zero, confirming they are opposites.
Explanation:
When we refer to numbers that are not integers but are opposites, we are seeking pairs of numbers whose sum is zero. Integers are whole numbers such as -1, 0, and 1, which do not include fractions or decimals. On the other hand, rational numbers are ratios of integers like 2/1 or 3/4, and these can be non-integers.
Consider the rational numbers 1/2 and -1/2; these are opposite numbers because they add up to zero. Similarly, another pair could be 3.5 (which is the same as 7/2) and -3.5 (or -7/2). These numbers are not integers because they have fractional parts, yet they are opposites because their sum is zero.
In both cases, these pairs demonstrate the mathematical property that when a number is added to its opposite, the result is always zero, which is a fundamental aspect of additive inverses. This is how we can verify that 1/2 and -1/2, as well as 3.5 and -3.5, are non-integer opposites.

Julie and her brother go to Atlanta to ride the SkyView Ferris wheel. It measures 200 feet in diameter.
A)I want to know the distance around the Ferris Wheel. Would I use Circumference or Area?
B)What is the formula needed to solve this problem?Look in your notes!
C)What is the distance traveled in one rotation? Explain how you used the formula to solve the problem.
The distance around the wheel is 628 feet and distance traveled in one rotation is equal to 628 feet
Solution:
Julie and her brother go to Atlanta to ride the SkyView Ferris wheel.
It measures 200 feet in diameter
Diameter = 200 feet
We know that diameter is twice of radius
[tex]diameter = 2 \times radius\\\\200 = 2 \times radius\\\\radius = \frac{200}{2}\\\\radius = 100[/tex]
Thus radius of wheel is 100 feet
The distance around the ferris wheel is the circumference of wheel
Since, wheel is of circular shape, we can use circumference of circle formula
The circumference of circle is given as:
[tex]C = 2 \pi r[/tex]
Where "r" is the radius and [tex]\pi[/tex] is a constant equal to 3.14
Substitute r = 100 we get,
[tex]C = 2 \times 3.14 \times 100 = 628[/tex]
Thus distance around the wheel is 628 feet
Distance traveled in one rotation = circumference of wheel
The distance traveled in one rotation is equal to 628 feet

Find the slope of each set of points.
a.) 4, 3 and -3, 4 b.) -2, 0 and (8, -4)
Answer:
1. (4, 3) and (-3, 4) has Slope = -1/7
2.(-2, 0) and (8, -4) has Slope = -2/5
Step-by-step explanation:
If two such points (a,b) and (c,d) are given, then the slope S is given as:
[tex]S = (\frac{d-b}{c-a} )[/tex]
Now here, the given set of points are:
1. (4, 3) and (-3, 4)
Here, the slope S = [tex](\frac{4-3}{-3-4}) = (\frac{1}{-7}) = -(\frac{1}{7})[/tex]
⇒ S = -1/7
1. (-2, 0) and (8, -4)
Here, the slope S = [tex](\frac{-4-0}{8-(-2)}) = (\frac{-4}{10}) = -(\frac{2}{5})[/tex]
⇒ S = -2/5
The stadium has a form of a rectangle with two semicircles attached to the short sides. The long side of a rectangle is 2 times longer than the short one. Construct the expression for the area of the stadium in terms of x, where x denotes a shorter side of the rectangle
Answer: [tex]2x^2+\frac{\pi x^2}{4}[/tex]
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
[tex]A_r=lw[/tex]
Where "l" is the lenght and "w" is the width.
The area of a semi-circle can be found with this formula:
[tex]A_{sc}=\frac{\pi r^2}{2}[/tex]
Where "r" is the radius.
Let be "x" the shorter side of the rectangle (which is also the diameter of the semi-circle).
Based on the information given in the exercise, you know that:
[tex]w=x\\\\l=2x[/tex]
Since the radius is half the diameter:
[tex]r=\frac{x}{2}[/tex]
Observe the figure attached, which shows the stadium.
The area of the stadium is the sum of the areas of the semi-cirlcles and the rectangle.
Therefore, you can construct the following expression for the area of the stadium is terms of "x":
[tex](2x)(x)+\frac{\pi (\frac{x}{2})^2}{2}+\frac{\pi (\frac{x}{2})^2}{2}[/tex]
Simplifying it, you get:
[tex](2x)(x)+\frac{\frac{\pi x^2}{4}}{2}+\frac{\frac{\pi x^2}{4}}{2}=2x^2+\frac{\pi x^2}{4}[/tex]
The expression for the area of the stadium in terms of x is 2x^2 + πx^2/4.
Explanation:The area of the stadium can be calculated by first finding the area of the rectangle and then adding the areas of the two semicircles. The long side of the rectangle is 2 times longer than the short side, so the dimensions of the rectangle are x for the short side and 2x for the long side. Therefore, the area of the rectangle is A = x * 2x = 2x^2. The formula for the area of a semicircle is A = πr^2/2, where r is the radius of the semicircle. In this case, the radius is x/2 since it is half of the short side of the rectangle. So, the area of one semicircle is π(x/2)^2/2 = πx^2/8. Since there are two semicircles, the total area of the semicircles is 2 * (πx^2/8) = πx^2/4.
Adding the area of the rectangle and the area of the semicircles, we get the expression for the total area of the stadium: A = 2x^2 + πx^2/4.

use the formula f=9/5c+32 to convert -20 degrees f
Answer:
c ≈ -29°
Step-by-step explanation:
To convert Fahrenheit to Celsius using the formula, substitute the degrees for Fahrenheit "f", then isolate Celsius "c".
f = [tex]\frac{9}{5}c[/tex] + 32
-20 = [tex]\frac{9}{5}c[/tex] + 32 Substitute "f" for -20
-20 - 32 = [tex]\frac{9}{5}c[/tex] + 32 - 32 Subtract 32 from both sides
-20 - 32 = [tex]\frac{9}{5}c[/tex] +32-32 cancels out to 0. Simplify left side
-52 = [tex]\frac{9}{5}c[/tex]
-52/[tex]\frac{9}{5}[/tex] = [tex]\frac{9}{5}c/\frac{9}{5}[/tex] Divide by 9/5 on both sides
-52/[tex]\frac{9}{5}[/tex] = c
-52[tex]*\frac{5}{9}[/tex] = c When dividing a fraction, flip the fraction and change to multiplication
[tex]\frac{-52*5}{9}[/tex] = c Multiply by combining into the numerator
[tex]\frac{-260}{9}[/tex] = c Use a calculator
c = -28.8888888889°
c ≈ -29° Round to the nearest degrees
Therefore -20°F is about -29°C.

Is 3 a solution of 2n - 6 = 5n - 15
Answer: Yes
Step-by-step explanation: Here, we want to decide if 3 is a solution for the equation 2n - 6 = 5n - 15. We can do this by simply plugging in 3 for n. If the statement holds true when 3 is plugged in for n, then 3 is a solution.
Plugging in 3 for n, we have 2(3) - 6 = 5(3) - 15.
2(3) is equal to 6 and if we subtract 6 we get 0.
On the right side, 5(3) is equal to 15 and if we subtract 15 we get 0.
0 = 0 is a true statement so yes,
3 is a solution for the equation 2n - 6 = 5n - 15

The statement is not reversible.
A reversible statement is one where the implication goes both ways. In simpler terms, if the statement is true, its converse (reversing the hypothesis and conclusion) must also be true, and vice versa.
The statement is: "If (x=3) then (x²=9)". The converse, "If (x² = 9) then (x = 3)" is not always true. For example, if x = -3, then x² is also 9.
A biconditional statement is true if and only if both the statement and its converse are true. Because the converse of the original statement is not always true, the biconditional statement " (x = 3) if and only if (x² = 9)" is also not true.

Sharmaine works 30 hours at an exclusive restaurant. She earns
$3.50 per hour plus tips. In one week, she earned $1,250.00 in tips. What was Sharmaine’s total income?
Answer:
Sharmaine had an income of US$ 1,355 that week.
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Hours per week Sharmaine works at an exclusive restaurant = 30
Salary of Sharmaine = US$ 3.50 per hour + tips
Tips of the week = US$ 1,250
2. What was Sharmaine’s total income?
Total income = Tips + Rate per hour
Total income = 1,250 + (3.5 * 30)
Total income = 1,250 + 105
Total income = 1,355
Sharmaine earned $105.00 from her hourly job and $1,250.00 in tips, making her total income $1,355.00 for the week.
Explanation:The student asked about Sharmaine's total income for a week. Sharmaine earns an hourly wage plus tips at a restaurant. To calculate her total income, we need to add her earnings from her hourly rate to her earnings from tips.
First, we determine her earnings from her hourly wage. She works 30 hours at $3.50 per hour. So, her income from her hourly wage is 30 hours × $3.50/hour = $105.00.
Next, we add her earnings from tips. Sharmaine earned $1,250.00 in tips for the week.
Her total income for the week is her hourly earnings plus her tips: $105.00 (hourly earnings) + $1,250.00 (tips) = $1,355.00.
Therefore, Sharmaine's total income for that week is $1,355.00.
