Which equation is non-linear?
A) [tex]y=3x^3-10[/tex]
B) [tex]y=1/2x+4[/tex]
C) [tex]y=4x-5/3[/tex]
D) [tex]-3x--7y=-21[/tex]
Answers
Answer:
[tex]\huge\boxed{\text{A is not linear.}}[/tex]
Step-by-step explanation:
Linear equations are equations that, when graphed, form a "line" and have a constant rate of change.
Usually, these are in the form [tex]y=mx+b[/tex] when put in that order.
There are a few types of equations, I'll list some of the major ones
Linear = has a constant rate of changeExponential = increases for x as the exponent Quadratic = is in a binomial, trinomial, or polynomial - it has a vertex
Linear functions are usually in the form [tex]y=mx+b[/tex]
Exponential functions are usually in the form [tex]y=b^x[/tex]
Quadratic functions are usually in the form [tex]ax^2 + bx + c[/tex]
We must note that linear functions can not
A) Have an exponent on any x term
B) Have x and y multiplied by each other
We can see that every equation, except A
A) Follows the form [tex]y=mx+b[/tex] ([tex]-3x--7y=-21[/tex] can be simplified to [tex]y= \frac{3}{7}x-3[/tex])
B) Does not have any exponents on their x terms
That leaves A) to be the equation that isn't linear.
Hope this helped!
Answer:
Equation A is non-linear.
Step-by-step explanation:
We are given four equations in which we need to determine if they are linear or non-linear relationships.
Firstly, we need to know some information about linear equations:
Linear equations cannot have an exponent.Linear equations have a constant slope and are straight lines.Linear equations can be negative or positive.Linear equations have a domain of all real numbers. They also have a range of all real numbers.Now, in order to check this easily, we need to place these equations into slope-intercept form.
Equation A
[tex]\displaystyle y = 3x^3 - 10[/tex]
We see that this has an exponent, so this cannot be a linear equation.
In fact, because it is cubed, this is called a cubic function. Therefore, equation A is not a linear equation.
Equation B
[tex]\displaystyle y = \frac{1}{2}x + 4[/tex]
This equation does not have a exponent. It also has a slope and a y-intercept. Therefore, equation B is a linear equation.
Equation C
[tex]\displaystyle y = 4x -\frac{5}{3}[/tex]
The equation does not have a exponent. It also has a slope and a y-intercept. Therefore, equation C is a linear equation.
Equation D
[tex]-3x--7y = -21[/tex]
First off, we need to get this equation into slope-intercept form, if possible.
[tex]\displaystyle -3x -- 7y = -21\\\\-3x + 7y = -21 \ \ \ \text{Change the sign on 7y.}\\\\7y = 3x - 21 \ \ \ \text{Move 3x to the other side by adding.}\\\\\frac{7y}{7}=\frac{3x-21}{7} \ \ \ \text{Divide both sides by 7 to isolate y.}\\\\\bold{y = \frac{3}{7}x-3}[/tex]
Our final equation is [tex]\displaystyle y = \frac{3}{7}x-3[/tex].
The equation does not have an exponent. It has a constant slope and a y-intercept. Therefore, equation D is a linear equation.
Let's check our equations:
Equation A: [tex]\displaystyle y = 3x^3 - 10 \ \text{X}[/tex]Equation B: [tex]\displaystyle y = \frac{1}{2}x + 4 \ \checkmark[/tex]Equation C: [tex]\displaystyle y = 4x -\frac{5}{3} \ \checkmark[/tex]Equation D: [tex]\displaystyle y = \frac{3}{7}x-3 \ \checkmark[/tex]Therefore, we have determined that Equation A is not a linear equation, making it non-linear.

At what point does the graph of 3x + 4y = 15 intersect the graph of x^2 + y^2 = 9? Express any non-integer coordinate as a common fraction.
Answers
Answer
12 and 36 and 13
If you need an explanation;
let's first isolate x in 3x + 4y = 15 ---
x = (15 - 4y) / 3
now substitute as x in the second equation provided ---
((15 - 4y) / 3)^2) + y^2 = 9,
((15 - 4y) / 3)^2) +( 3y/3)^2 = 9,
((15 - 4y)^2 + (3y/3)^2)/3^2 = 9,
225 - 120y +25y^2/9 = 9,
225 - 120y +25y^2 = 81,
25y^2 - 120y + 144 = 0
we now solve using the quadratic formula ---
[tex]y_{1,\:2}=\frac{-\left(-120\right)\pm \sqrt{\left(-120\right)^2-4\cdot \:25\cdot \:144}}{2\cdot \:25}\\=\frac{-\left(-120\right)\pm \sqrt{0}}{2\cdot \:25}\\=\frac{-\left(-120\right)\pm \sqrt{0}}{2\cdot \:25}\\\\= 12/5[/tex]
So then x = (15 - 4*12/5)/3 = 9/5. Our solution = (9/5, 12/5)

Jessica is 5 years older than her sister Jenna. Jenna tells her sister that in 5 years, she will be as old as Jessica was 5 years ago. If Jenna’s age is x, which equation represents the situation? How many solutions does the equation have?
A.
x + 5 = (5 − x) − 5, which has one solution
B.
x + 5 = (x + 5) − 5, which has infinitely many solutions
C.
x + 5 = (x + 5) − 5, which has no solution
D.
x + 5 = (5 − x) − 5, which has infinitely many solutions
E.
Answers
Answer:
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = x
That equation has not any solution, because it reduces to 5 = 0, which is an absurd.
So, the conclusion is that information given by Jenna is wrong.
It is logical: if the difference of the ages is 5, in five years Jenna will have 10 years more than what her sister had 5 years ago, no 5 as she told Jessica.
Answer:
(x + 5) + 5 = (x + 5) + 5, which has infinitely many solutions

The two numbers are __ and __.84 is a multiple of each of its factors. The factors with a difference of 5 are__ and __ their LCM is 84.
Answers
Answer:
factor 1 = x
factor 2 = x - 5
(factor 1) * (factor 2) = 84
(x) * (x - 5) = 84
x² - 5x = 84
x² - 5x - 84 = 0
(x - 12) (x + 7) = 0
x - 12 = 0 or x + 7 = 0
x = 12 or x = -7
factor 2 = x - 5 = (12) - 5 = 7 or (-7) - 5 = -12
