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)

Answers

Answer:

use it as so-

4 cups/1 x 1 pint/2 cups= 2 pints

2 pints/1 x 1 quart/2 pints = 1 quart

1 quart/1 x 1 gallon/4 quarts= 1/4 gallons

therfore, 4 cups is equal to 1/4 gallons. hope this helps!

In order to convert gallons to cups using more than one conversion factor, first convert gallons to quarts and then convert quarts to cups.

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.

The least common multiple of two numbers is 84, and one of the numbers is 5 less than the other number. What are the numbers? Complete the explanation.


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

Answer: 12, 7     or    -7, -12

Answer:

Below.

Step-by-step explanation:

84 = 7 * 12.

The 2 numbers are 7 and 12.

5 + 5Consider triangle ABC. Triangle A B C. Angle C is 80 degrees and angles B and A are y degrees. What is the value of y in the triangle? Angle y = °

Answers

The value of Angle Y is 100 because a triangle is 180 degrees and angle c is 80 which means 180 minus 80 equals 100

Answer:

y=50°

Step-by-step explanation:

if all triangles add up to 180° you would subtract the angle you already know(80) from 180 which would be 100°

since there are 2 corners we dont know you would divide by 2 which would be 50°

Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).

Answers

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.
