Answer:

x can be anything higher than 45. For example, x can be 50. That would be 20 (or x) is greater than (>) 15.

Answer:

The answer is D

Step-by-step explanation:

This problem may look complex but it isn't; the variables in the "x" column represent what would be substituted for x, and y would be what the equation would equal AFTER substituting the x variable into the equation

So for example, using d's table, I would substitute -4 for x: y = -3(-4) + 2, the answer would be 14, which is in the y column. I will do the same thing using the next variable in the x column, y = -3(-2) + 2, that would equal 8, which is also in the y column, this would not serve true in any other tables.

The triangle of the 360 squared by the square

Answer:

n-8

Step-by-step explanation:

difference means subtraction so it can't be 8n which is multiplication or 8-0 because n is not represented.

Answer:

A

Step-by-step explanation:

We have the two functions:

[tex]f(x)=3x^2-2x\text{ and } g(x)=9x^2-x+7\\[/tex]

And we want to find:

[tex](f-g)(x)[/tex]

This is equivalent to:

[tex]=f(x)-g(x)[/tex]

Hence, by substitution:

[tex]=(3x^2-2x)-(9x^2-x+7)[/tex]

Distribute:

[tex]=(3x^2-2x)+(-9x^2+x-7)[/tex]

Rearrange:

[tex]=(3x^2-9x^2)+(-2x+x)+(-7)[/tex]

Combine like terms:

[tex]=-6x^2-x-7[/tex]

Hence, our answer is A.

Answer:

Step-by-step explanation:

3x^2 - 2x - 9x^2 + x - 7

-6x^2 - x - 7

answer is A

The required value is 27/8, which is determined when we compute the expression (8-5) ÷ 2 raised to the third power. Thus, the option (C) is correct.

To find the equivalent expression to (8-5) ÷ 2 raised to the third power, we first simplify the expression inside the parentheses:

(8-5) ÷ 2 = 3 ÷ 2.

Next, we raise this simplified expression to the third power:

(3 ÷ 2)³

To evaluate this, we cube both the numerator and denominator:

(3^3) ÷ (2³) = 27 ÷ 8.

Therefore, the expression (8-5) ÷ 2 to the third power is equivalent to 27/8.

Hence, the correct answer is option C: 27/8.

This means that 27/8 is the value we get when we compute the expression (8-5) ÷ 2 raised to the third power.

Answer:

A. Pontiac

Step-by-step explanation:

Camry's mileage = Miles travelled / gallons of fuel used

= 196 / 11

= 17.82

Pontiacs mileage = Miles travelled / gallons of fuel used

= 220 / 13

= 16.92

Bluck's mileage = Miles travelled / gallons of fuel used

= 356 / 15

= 22.25

Toyotas mileage = Miles travelled / gallons of fuel used

= 583 / 21

= 27.76

The car with the best mileage is Pontiac

Answer:

7x-4x«21

3x«21

divide both sides by 3

they a move up 5 minutes eace half mile

dont come at me if it is wrong :)

Answer:

Step-by-step explanation:

Cost ≤ per day amount + daily mileage amount.   * miles

75 ≥ 30 + daily mileage amount * miles

That's as far as I can take you. Two other equations are impossible without the daily mileage amount.

I can make one up. Suppose it is 75 cents a mile

75 ≥ 30 + 0.75 * x       Subtract 30 from both sides

75 - 30 ≥ 0.75*x

40 ≥ 0.75*x                 Divide by 0.75

40/0.75 ≥ x

53.33 miles = x  

Anything more and you are going over budget. Anything less is fine.

This is enough to get you started without knowing what the rate per mile is.

Answer:

The inverse of the function f(x) is h(x) = 4x + 48 ⇒ (D)

Step-by-step explanation:

To find the inverse of a function do these steps

Let us do these steps to solve the equation

∵ f(x) = [tex]\frac{1}{4}[/tex]x - 12

→ Replace f(x) by y

∴ y = [tex]\frac{1}{4}[/tex]x - 12

→ Switch x and y

∴ x =  [tex]\frac{1}{4}[/tex]y - 12

→ Add 12 to both sides

∵ x + 12 =  [tex]\frac{1}{4}[/tex]y - 12 + 12

∴ x + 12 =  [tex]\frac{1}{4}[/tex]y

→ Multiply each term by 4

∵ 4(x) + 4(12) = 4([tex]\frac{1}{4}[/tex]y)

∴ 4x + 48 = y

→ Switch the two sides

∴ y = 4x + 48

→ Replace y by h(x)

∴ h(x) = 4x + 48

∴ The inverse of the function f(x) is h(x) = 4x + 48

Answer:

h(x) = 4x + 48 ⇒ (D)

i just did it

Answer:

I would, but the way this is set up is VERY confusing. sorry. maybe try to fix it after copying and pasting to make sure it makes sense.

The evaluated values of the step function for the given input values are as g(-2) = -4, g(2) = 3, and g(5) = 5.

To evaluate the step function g(x) for the given input values, we need to follow the conditions specified for each interval.

Given the step function:

g(x) =

-4, x < -1

-1, -1 ≤ x < 2

3, 2 ≤ x < 4

5, x ≥ 4

Let's evaluate the step function for each input:

g(-2):

Since -2 is less than -1, the condition for the first interval is satisfied. Therefore, g(-2) = -4.

g(2):

Since 2 is less than or equal to 4, the condition for the second interval is satisfied.  Therefore, g(2) = 3.

g(5):

Since 5 is greater than or equal to 4, the condition for the last interval is satisfied. Therefore, g(5) = 5.

Hence, we have:

g(-2) = -4

g(2) = 3

g(5) = 5

#SPJ2

Answer: They are diffrent

Step-by-step explanation: The logistic equation was first published by Pierre Verhulst in 1845. This differential equation can be coupled with the initial condition P(0) = P0 to form an initial-value problem for P(t). Suppose that the initial population is small relative to the carrying capacity. Then P K is small, possibly close to zero.

The logistic regression coefficients are the coefficients b 0, b 1, b 2,... b k of the regression equation: An independent variable with a regression coefficient not significantly different from 0 (P>0.05) can be removed from the regression model (press function key F7 to repeat the logistic regression procedure).

By the way, this is copied from the internet.

Answer:

Se necesitan 37.5 litros del preparado que contiene 5% de jugo natural, y 12.5 litros del que contiene 25%.

Step-by-step explanation:

Primero calculamos la cantidad total de jugo natural que se necesita, a partir del volumen de jugo mixto que se quiere vender:

Ahora, que X sean los litros del preparado con jugo de 5%, y que Y sean los litros del preparado con jugo de 25%:

La suma de ambos preparados tiene que ser 50 L:

1.    x + y = 50

La suma del jugo natural tiene que ser 5:

2.   x*5/100 + y*25/100 = 5

Answer:

y = -3x + 10

Step-by-step explanation:

y = mx + b

plug in numbers to the equation

1 = (-3)(-3) + b

multiply the slope -3 and -3

1 = (9) + b

subtract 9 from both sides

-8 = b

Now plug in the slope and b

y = -3x - 8

Answer:

The equation I got was y= 3x + 10

Step-by-step explanation:

All you need to do is use the formula y= mx + b.
