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 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:

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:

Therefore, we have determined that Equation A is not a linear equation, making it non-linear.

Step-by-step explanation:

Im not to sure theirs not enough information

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

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)

Answer:

ced is 110 degrees

Step-by-step explanation:

because ECD is 28 degrees and 28+42=70 and a triange always = 180 degrees so it would have to be 110

The measure of ∠CED is 110 degrees by angle sum property of the triangle.

We are given that line AB is parallel to line CD.

The measure of ∠ABC is 28° and the measure of ∠EDC is 42°

An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.

We know that line AB is parallel to line CD.

So according to alternate interior angles measure of ∠ABC is 28° will be equal to BCD.

Thus, Angle BCD= 28 degrees

Hence, in a triangle CED

∠CED + ∠EDC + BCD = 180

∠CED + 28 + 42 = 180

∠CED = 180 - 70

∠CED = 110 degrees

Therefore, the measure of ∠CED is 110 degrees by angle sum property of the triangle.
