Answer:

xy=4 AND

y=7x^4

Step-by-step explanation:

B. xy = 4 is a hyperbola, which is a two-piece curve with an asymptote.

C. y = 7x^4

is a quartic, also a curve.

You can tell the other equations ARE linear, because they have no exponent on the variables. (If you solve the "xy" equation for y, the x ends up on the bottom of a rational expression--not linear)

[tex]\huge\fbox{y=-4.4x+6.8}\checkmark[/tex]

[tex]\huge\text{Solution:}[/tex]

Hi there!

We are given the slope of the line and its y-intercept.

So, we can easily identify the equation of the line.

The equation of the line is usually written in slope-intercept form.

Slope-Intercept Form looks like this:

[tex]\fbox{y=mx+b}[/tex]

Where m is the slope and b is the y-intercept.

In this case, the slope is -4.4, and the y-intercept is 6.8, so all we need to do is plug in -4.4 instead of m and 6.8 instead of b:

[tex]\longmapsto[/tex][tex]\fbox{y=-4.4x+6.8}[/tex] (Answer)

Answer:

1/6

Step-by-step explanation:

hope this helps!!

Answer:

1/6

Step-by-step explanation:

1/2 ÷ 3 → 1/2 ÷ 3/1     *Let's write both as fractions to make things easier

1/2 ÷ 3/1  → 1/2 · 1/3    *Change the division sign into multiplication and turn      3/1 into its reciprocal which is 1/3 (aka just change the numerator into denominator and denominator into numerator)

1/2 · 1/3 = 1/6   *Multiply straight across! So, 1 · 1 = 1 (numerator) over 2 · 3 = 6 (denominator)

Answer:

Step-by-step explanation:

Pretty sure it equals 360 degress overall so 360 -313 = ^^^^^^^^^^^^

Answer:

no

Step-by-step explanation:

using the values of the ordered pair in the first equating we get :

2 = 3×5 - 13 = 15 - 13 = 2

that fits.

but when using them in the second equation we get :

4×5 - 3×2 = 17

20 - 6 = 17

14 = 17

and that is wrong.

that means the point (5, 2) is not on the second line, so the point cannot be the crossing point (= solution, where both equations deliver the same result) of both lines.

FYI

we would solve the system by using the first equality directly in the second equation :

4x - 3(3x - 13) = 17

4x - 9x + 39 = 17

-5x = - 22

5x = 22

x = 22/5 = 4.4

and y is then

y = 3×4.4 - 13 = 13.2 - 13 = 0.2

the actual solution of the system is therefore

(4.4, 0.2)

Answer:

y=5 x=110

Step-by-step explanation:

Answer:

x = 10 , y = 5

Step-by-step explanation:

It is given that x = 2y. Plug in 2y for x in the first equation, and then solve for the variable, y:

-4x  + 11y = 15

x = 2y

-4(2y) + 11y = 15

First, multiply, then combine like terms:

(-4 * 2y) + 11y = 15

(-8y) + 11y = 15

11y - 8y = 15

3y = 15

Isolate the variable, y. Divide 3 from both sides of the equations:

(3y)/3 = (15)/3

y = 15/3 = 5

Plug in 5 for y in one of the equations to solve for x:

x = 2y

x = 2(5)

x = 10

x = 10 , y = 5

The quadratic regression equation for this data set is [tex]\rm y=-0.143x^2+0.59x+2.82\\[/tex].

The general form of the quadratic equation is given by;

[tex]\rm ax^2+bx+c=0[/tex]

Where; a, b, and c are the constants.

x;   0       1         2        3          4         5

y;  2.82  3. 29  3. 46  3. 33   2. 88  2. 24

From the table when the value of x = 0 the value of y is 2.82.

Then,

[tex]\rm y=ax^2+bx+c\\\\x=0\\\\2.82=a0^2+b(0)+c\\\\c=2.82[/tex]

From the table when the value of x = 3 the value of y is 3.33.

[tex]\rm y=ax^2+bx+c\\\\x=3\\\\2.82=a(3)^2+b(3)+c\\\\9a+3b+2.82=2.82\\\\9a=-3b\\\\b=-3a\\\\[/tex]

From the table when the value of x = 5 the value of y is 2.24.

[tex]\rm y=ax^2+bx+c\\\\x=3\\\\2.24=a(5)^2+(-3a)(5)+c\\\\25a-15a+2.82=2.24\\\\40a=2.24-2.82\\\\10a=-0.68\\\\a= \dfrac{-0.68}{10}\\\\a=-0.143[/tex]

And the value of b is;

[tex]\rm b=3a\\\\b=3(-0.14)\\\\b=0.59[/tex]

Therefore,

The quadratic regression equation for this data set is;

[tex]\rm y=ax^2+bx+c\\\\y=-0.143x^2+0.59x+2.82\\\\[/tex]

Hence, the quadratic regression equation for this data set is [tex]\rm y=-0.143x^2+0.59x+2.82\\[/tex].

Step-by-step explanation:

Calculate the slope m using the slope formula

Step-by-step explanation:

given expression → x/y

we know,

x = 3 and y = 27

according to expression

3/27 → 1/9

therefore 1/9 is the answer.

Hope this answer helps you!

Answer:

1/9

Step-by-step explanation:

1. First, let's plug in the values of x and y.

2. Next, we have to simplify and find the greatest common factor between 3 and 27.

3. As you can see, 3 is the GCF of 3 and 27, so we divide both 3 and 27 by 3.

Therefore, the answer is 1/9!

Step-by-step explanation:

I am not sure I understand the numbers in the description, but I assume you meant that

the baseline is x/2 meter,

the height to the baseline is also x/2 meter.

the area is 32 m².

the area of a triangle is

baseline × height / 2.

so, here we have

32 = x/2 × x/2 / 2 = x²/4 / 2 = x²/8

x² = 32×8 = 256

x = 16 m

so the base and the height are both 16/2 = 8 m long.

Answer:

10,000 cm² in 1 m²

1,000,000 cm³ in 1 m³

Step-by-step explanation:

There are 100 cm in 1 m

Therefore, to find how many square cms are in 1 square meter, we need to square 100:  100² = 100 x 100 = 10,000

Therefore, there are 10,000 cm² in 1 m²

Therefore, to find how many cubic cms are in 1 square meter, we need to cube 100:  100³ = 100 x 100 x 100 = 1,000,000

Therefore, there are 1,000,000 cm³ in 1 m³

Answer:

1m^2 = 10,000cm^2 (10 thousand square centimeters)

1m^3 = 1,000,000cm^3 (1 million cubic centimeters)

Step-by-step explanation:

x^2 is the same as x × x

There are 100 sm in a meter, so in this case x = 100

100^2 = 100 × 100 = 10,000

x^3 is the same as x × x × x

100^3 = 100 × 100 × 100 = 1,000,000
