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.

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)

What is the Lenght and Width of  the Graden?

156

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

Answer: 12, 7     or    -7, -12

Answer: 147

Step-by-step explanation:

To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).

f(3)=2(3)²-4(3)+9         [exponent]

f(3)=2(9)-4(3)+9          [parenthesis]

f(3)=18-12+9                [subtract]

f(3)=6+9                       [add]

f(3)=15

Now, we find f(-3).

f(-3)=2(-3)²-4(-3)+9      [exponent]

f(-3)=2(9)-4(-3)+9         [parenthesis]

f(-3)=18+12+9               [add]

f(-3)=30+9                    [add]

f(-3)=39

With the values of f(3) and f(-3), we can evaluate the expression.

2(15)+3(39)                  [multiply]

30+117                          [add]

147

Now, we know the value is 147.

Explanation:

The two angles shown combine to 180 degrees because the angles form a straight line.

(3x+18)+(4x+15) = 180

7x+33 = 180

7x = 180-33

7x = 147

x = 147/7

x = 21
