Answer:

Vertical change = 4

Horizontal change = 1

Slope = 4

b  (y-intercept) = 2

Step-by-step explanation:

From the graph (notice it as also marked with an arrow) you can get the value of "b" (also called the -intercept) is "2"

Please notice that you have entered wrong values for the slope.

By using the points (0, 2), and (1, 6) which are marked on the graph, you estimate the slope doing:

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

in our case, the vertical change (y2 - y1) is : 6 - 2 = 4

The horizontal change is (x2 - x1) = (1 - 0) = 1

Then the slope is: 4 / 1 = 4

slope = 4

and "b" (or y-intercept) is 2

Answer:

7

Step-by-step explanation:

l = larger number

s = smaller number

l = 4s - 9

l + s = 26

so 4s - 9 + (s) = 26

simplify--> 5s - 9 = 26

--> 5s = 35

---> s = 7

substitute 7 for s to find l

l + 7 = 26

l = 19

Answer:

a) f(x) = x^2

b) f(x) = x

c) any pair of numbers

Step-by-step explanation:

The value of the exponential function f ( x ) = eˣ has the domain as the set of all real numbers

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential function be represented as A

Now , the value of A is

f ( x ) = eˣ   be equation (1)

And , exponential functions have a positive base, and a variable for an exponent.

The scope of an exponential function encompasses all real numbers since all powers of a positive base are defined. All the values of the function will be positive since we begin with a positive base and powers of a positive base are always positive.

The function never accepts the value 0 or any negative number, as indicated by that. An exponential function can only be applied to positive values. Other than that, their activities are varied.

And , the domain is all real numbers and the range is all positive real numbers

Hence , the value of the exponential function is a set of real numbers

42/9=14/3

Step-by-step explanation:

Simplificación de Fracciones

Una fracción de la forma x/y puede ser representada de infinitas maneras, siempre y cuando produzcan el mismo resultado.

Por ejemplo, las fracciones 5/3 y 10/6 son equivalentes porque producen el mismo resultado. Obsérvese que tanto el numerador como el denominador en la segunda están multiplicados por 2.

Igualmente si tenemos 10/6, podemos obtener 5/3 dividiendo a ambos por 2.

La fracción 42/9 puede convertirse a una fracción equivalente dividiendo ambos términos por 3 para obtener 14/3

Answer:

x = 67°

Step-by-step explanation:

there are 180 degrees in a triangle and we know that the two corners equal the same amount. so we can set up an equation like this:

180 = 46 + 2x

so now lets subtract 46 from both sides to simplify the equation.

134 = 2x

now we can divide both sides by 2 to get our final answer.

67 = x

we can check our answer by solving this expression:

67 + 67 + 46 = ?

after adding these together, we get 180 so we know our answer is correct.

Answer:

A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

Step-by-step explanation:

The two numbers from the equations are 16 and -52

The first number is 16

The second number is -52

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first number be = x

Let the second number be = y

So , the equation will be

Let the sum of two numbers be = -36

And the equation will be

x + y = -36   be equation (1)

Let the difference of two numbers be = 68

And the equation will be

x - y = 68   be equation (2)

Subtracting equation (1) from equation (2) , we get

On simplifying the equation

2x = 32

Divide by 2 on both sides of the equation , we get

x = 16

The equation will be

Substituting the value of x in the equation , we get

x + y = -36

16 + y = -36

Subtracting 16 on both sides , we get

y = -52

Hence , the two numbers are 16 and -52

Answer:

the answer is 12

Step-by-step explanation:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

y ∝ x

y = kx

k = 0.6

The value of x when y = 18 is 30.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 5y is an equation.

2x + 4 + 9 is an equation.

We have

if y varies directly as x.

This can be written as,

y ∝ x

y = kx _____(1)

From (1),

y = 6 when x= 10

6 = 10k

k = 6/10

k = 0.6

Now,

y = 0.6x

when y = 18,

18 = 0.6x

Divide both sides by 0.6.

x = 18/0.6

x = 180/6

x = 30

Thus,

y ∝ x

y = kx

k = 0.6

The value of x when y = 18 is 30.

Answer:

250

Step-by-step explanation:

From the question given above,

y varies directly as the cube of x. This can be written as

y ∝ x³

y = Kx³

Next, we shall determine the value of the constant (K) as follow:

y = 54

x = 3

K =?

y = Kx³

54 = K × 3³

54 = K × 27

Divide both side by 27

K = 54/72

K = 2

Finally, we shall determine the value of y when x is 5.​ This can be obtained as follow:

x = 5

K = 2

y =?

y = Kx³

y = 2 × 5³

y = 2 × 125

y = 250

Therefore, the value of y is 250

its 6.6 (I think???)

Step-by-step explanation:

the volume of that box is 105 and 105 x 6.6 is 693. please forgive me if I'm wrong i havent learned this yet.

The dimensions of the new box are 7 cm, 9 cm, and 11 cm.

The original volume of the box is 357 = 105 cm3. After the dimensions are increased by x, the new volume is (3+x)(5+x)(7+x) = 693 cm3.

Expanding the product gives [tex]x^3+15x^2+71x-588 = 0.[/tex]

This cubic equation can be solved for x, and the only real solution is x = 4.

Therefore, the value of x that will produce a box with a volume of 693 cm3 is 4. This means that the dimensions of the new box are 7 cm, 9 cm, and 11 cm.

The answer is 0.94 !!!

The probability that a randomly selected statistics student is a business major or likes grilled cheese is 0.94.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that the statistics class has 50 students and among those students, 42 are business majors, and 8 like grilled cheese. Of the business majors, 3 like grilled cheese.

The probability will be calculated as:-

P(AUB) = P(A) + P(B) - P(A[tex]\cap[/tex]B)

[tex]P(AUB)=\dfrac{42}{50}+\dfrac{8}{50}-\dfrac{3}{50}[/tex]

[tex]P(AUB) = \dfrac{50-3}{50}[/tex]

[tex]P(AUB)=\dfrac{47}{50}[/tex]

P(AUB) = 0.94

Therefore the probability that a randomly selected statistics student is a business major or likes grilled cheese is 0.94.
