Is 5x/4-y/3 = 6 linear or non linear
Answer:
linear
Step-by-step explanation:
To tell if a function is linear, simply look at the exponents of the variables "x" and "y". Both of these exponents will have to be one and only one (1), any other exponent will turn the function into non-linear. Radicals also count as exponents different than one, because they are fractional exponents. Since there are no radicals or exponents written in this equation, we can conclude that all variable exponents are one (1), hence it's a linear equation.

What is the equation, in stanard form, of a parabola that models the values in the table x-3 0 2 f(x) -8 -2 -28
The equation of the parabola is f(x)= 7x²+5x-2 when values of the x are -3,0,2 and the f(x) are -8,-2,-28.
Given that,
The values of the x are -3,0,2 and the f(x) are -8,-2,-28
We have to find the equation of the parabola with the x and f(x) values.
We know that,
The equation of the parabola of the form f(x) = ax²+bx+c
So,
-3a-3b+c=-8 ----->equation(1)
c=-2
2a+2b+c=-28 ------>equation(2)
Substituting c=-2 in equation(1) and equation(2)
-3a-3b-1+8=0
-3a-3b+7=0 ------>equation(3)
2a+2b-2+28=0
2a+2b+26=0 ------>equation(4)
Subtracting 2×equation(3) and 3×equation(4)
b=5
Substituting in equation(1)

The correct order for the lowest to highest unit price is:
Brand C < Brand A < Brand B.
In this question we have been given the prices and unit conversions.
We need to rank the brands from lowest to highest unit price.
Brand A: $1.48 for 2.5 pounds
Brand B: $1.30 for 907.18 grams; 1 pound is approximately 453.59 grams
Brand C: $1.55 for 50 ounces; 1 pound is equal to 16 ounces
Given that:
1 pound = 453.59 grams
And 1 pound = 16 ounces
After conversion:
2.5 pounds = 2.5x16 ounces
= 40 ounces
and 907.18 grams = (907.18x16/453.59) ounces
= 32 ounces
Now we find the unit price for each brand by unitary method.
Brand A: $1.48 for 40 ounces
so, the unit price = 1.48/40
= $0.037 per ounce
Brand B: $1.30 for 32 ounces
unit price = 1.30/32
= $0.041 per ounce
Brand C: $1.55 for 50 ounces
Unit price = 50/1.55
= $0.031 per ounce

By analyzing the given line mathematically, we get the required slope of the line as 3.
What is Slope ?A line's steepness and direction can be expressed as a value called slope. It is frequently represented in variable format by the letter m. Its gradient or rate of change are other names for a line's slope.
The rise over run or slope formula, often known as the vertical change in y divided by the horizontal change in x, To determine the change in y over the change in x, the slope formula requires two points, (x1, y1) and (x2, y2).
As from the Line,
Two points = (1,2), (2,5)
(x1, y1) = (1,2)
(x2,y2) = (2,5)
Using two point we can calculate slope as
= [tex]\frac{y2-y1}{x2-x1}[/tex]
Putting the points in the formula, we get:
[tex]\frac{5-2}{2-1}[/tex]
= 3

What is meant by direct relation?A direct relation exists when the two variables rise or fall together. In a straight link, as X rises, Y rises as well. A straight relationship will always have a positive slope on a graph.
What is speed?Speed is the pace at which an object's position changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).

An = -3.5(-2)ⁿ⁻¹ and -3.5 are the Nth and first terms of the above sequence, respectively.
What is Geometric sequence?Every term in a geometric series is obtained by multiplying the term before it by the same number. Aₙ = a₁ rⁿ⁻¹ is the general phrase for it. The common ratio is denoted by the number r.
Given a₂ = 7 and a₅ = −56 for a geometric sequence.
From the general formula of geometric sequence's nth term
Aₙ = a₁ rⁿ⁻¹
Thus
A₂ = 7 = a₁ r²⁻¹ = a₁ r
A₅ = -56 = a₁ r⁵⁻¹ = a₁ r⁴
comparing both equations
A₂/ A₅ = a₁ r / a₁ r⁴
=> -7/56 = 1/r³
=> r³ = -8
=> r = -2
putting this value of r in equation 1
a₁ = -7/2
Hence, for the nth term of the sequence
Aₙ = -7/2(-2)ⁿ⁻¹
