Check if a relation is a function by looking at the x's.

No repeated x's? Then it's a function.

Repeated x's but the y is the same y both times? It's a function.

Repeated x's and different y's? NOT A FUNCTION.

Answer:

  1 solution

Step-by-step explanation:

The coefficients of x are different on each side of the equal sign, so this equation has one solution.

_____

Additional comment

If the x-coefficients are the same on each side of the equal sign, then you need to look at the constants. If they are the same, there are an infinite number of solutions; if they are different, no solutions.

This equation simplifies to ...

  3x -3 = 2x +9

  x = 12 . . . . . . . . add 3-2x to both sides

The solution of expression by applying distributive property and combining like terms,

⇒ x = 12

Given that,

The mathematical expression is,

⇒ 3(x - 1) = 2x + 9

Now, simplify the expression by applying distributive property and combining like terms,

⇒ 3(x - 1) = 2x + 9

Apply distributive property,

⇒ 3x - 3 = 2x + 9

Combine like terms,

⇒ 3x - 2x = 9 + 3

Therefore, the solution of expression is,

⇒ x = 12

Step-by-step explanation:

The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]\rm a^c=b[/tex] can be written as [tex]\rm log_ab=c[/tex].

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

Given to us

2⁵ = 32

As we know that we can convert a number powered to another number therefore exponential function into a log function, thus,

[tex]\rm 2^5=32\\\\log_25=5[/tex]

Hence, The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

Answer: 1/4

Step-by-step explanation:

slope = (y2 - y1) / (x2 - x1)

         = (6 - 5) / (5 - 1)

         = 1/4

Answer:

x = - 12, y = 9

Step-by-step explanation:

Given the 2 equations

3x + 6y = 18 → (1)

x + 3y = 15 → (2)

Multiplying (2) by - 3 and adding to (1) eliminates the term in x

- 3x - 9y = - 45 → (3)

Add (1) and (3) term by term to eliminate x

- 3y = - 27 ( divide both sides by - 3 )

y = 9

Substitute y = 9 into either of the 2 equations and evaluate for x

Substituting into (2)

x + 3(9) = 15

x + 27 = 15 ( subtract 27 from both sides )

x = - 12

Solution is (- 12, 9 )

The length of the ladder is 10:44 meters.

Step-by-step explanation:

Base of the ladder is 3 meters away from the house. So base =3 m

one side 10 meters and base is 3 meters

well, from 800 to 600 is 200 bucks.

if we take 800 to be the 100%, what is 200 off of it in percentage?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 800 & 100\\ 200& x \end{array} \implies \cfrac{800}{200}=\cfrac{100}{x}\implies 4=\cfrac{100}{x} \\\\\\ 4x=100\implies x=\cfrac{100}{4}\implies x=25[/tex]

Answer:

Step-by-step explanation:

focus of the parabola is (2,0) and directrix is x=-2. Here,a=2.So, Equation becomes, y2=4∗2x⇒y2=8x, which is the required equation of parabola.

The equation of a parabola with the given focus and directrix is x²-10x+74=14y.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line

Given that, a parabola has focus (5,7) and directrix y=0.

When the focus (h, k) of a parabola and the equation of the directrix y = c are given, the equation of the parabola is given by (x-h)²+k²-c²=2(k-c)y

Here, y=c=0

Now, (x-5)²+7²-0²=2(7-0)y

x²-10x+25+49=14y

x²-10x+74=14y

Therefore, the equation of a parabola is x²-10x+74=14y.

Answer:

C. 108

Step-by-step explanation: This is the correct answer on Edge 2021, just took the quiz and made a 100%. Hope this helps ^-^.

The value of 'x' is 108° . Option C

From the illustration,

Angle RQS is at Q = x degrees

Angles KLM is at L = x - 36 degrees

Note that they are corresponding angles

Corresponding angles sum up to 180°

Then equate both angles to 180 degrees

x + x - 36 = 180°

Collect like terms

2x = 180 + 36

2x = 216

Make 'x' subject of formula

x = 216 / 2

x = 108°

Therefore, the value of 'x' is 108° . Option C

Since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

A regular polygon is any n-sided polygon that has equal interior angles and equal sides.

Thus:

Therefore:

x = 360 - 120 - 108

x = 132°

Thus, since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

The table is an illustration of a quadratic regression model

The function that best models the data is y = -60.4x^2 +348.1x -334.2

To determine the function that models the data, we make use of a graphing calculator.

Using the graphing calculator, we have the following calculation summary

a = -60.4

b = 348.1

c = -334.2

A quadratic regression model is represented as:

y = ax^2 + bx + c

So, we have:

y = -60.4x^2 +348.1x -334.2

Hence, the function that best models the data is y = -60.4x^2 +348.1x -334.2
