How do I solve for x?

Answer:

it would be A because if you repeat an x value it can cause it to be a a non-function

Answer:

The one of -[n+2n+3n+4n]/nlne(10) has fewer operations because the value of n is static.

The one of n! ( factorial ) is factorised up to n∞ hence has infinity operations.

Answer: The rate is increasing upwards, if that is what you were asking?

Step-by-step explanation: Let me know if you need anything else, please :)

The rate of change for payment option 1 is 1 and for payment option 2 is 0.25.

At 4th visit the cost of both the plans will be same.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is its graph or the rate of change is large.

We know the slope m = (y₂ - y₁)/(x₂ - x₁).

Payment option 1 has two points (0, 2) and (2, 4).

Slope(m₁) = (4 - 2)/(2 - 0).

Slope(m₁) = 2/2

Slope(m₁) = 1.

4 = 2(1) + b.

b = 2.

y = x + 2.

Payment option 2 has,

$0.25 every visit is $(1/4) and it is the rate of change or the slope.

y = 0.25x + 5.

The number of visits when the cost will be equal is when we'll equate these two equations,

x + 2 = 0.25x + 5.

x - 0.25x = 5 - 2.

0.75x = 3.

x = 3/0.75.

x = 4.

At 4 visits the cost of each plan will be the same.

Answer:

The midpoint of [tex]\overline{BD}[/tex] is [tex](\frac{a}{2},\frac{a}{2})[/tex].

Step-by-step explanation:

Consider the provided information.

We need to find the midpoint of [tex]\overline{BD}[/tex].

For this, we will use the midpoint formula: [tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

Now put [tex](x_1,y_1)=(0,a)[/tex] and [tex](x_2,y_2)=(a,0)[/tex] in the above formula and solve for M.

[tex]M=(\frac{0+a}{2},\frac{a+0}{2})[/tex]

[tex]M=(\frac{a}{2},\frac{a}{2})[/tex]

Hence, the midpoint of [tex]\overline{BD}[/tex] is [tex](\frac{a}{2},\frac{a}{2})[/tex].

Step-by-step explanation:

8 is even number which uses each of the digits exactly once.

Answer:

The answer is -4.

Step-by-step explanation:

It is -4 using the method of PEMDAS.  Subtract 4 and 2 together in the parentheses to get 2.  Multiply to the third root power to get 8.  Then, multiply -3 by 4 together to get -12.  Finally, subtract 12 from 8 to get -4 as your final answer.

Answer:

  1) 135°

  2) 0.77 units

  3) 0.92 units

  4) 6.12 units

  5) 2.83 square units

Step-by-step explanation:

1) The exterior angle at any vertex is 360°/n, where n is the number of sides. For the octagon, the exterior angle is 360°/8 = 45°. The interior angle will be the supplement of this: 180° -45° = 135°.

The measure of each interior angle is 135°.

__

2) Each sector of the octagon is an isosceles triangle with a central angle of 45° (also 360°/8). Since the radius is 1 unit, the length of one side is twice the sine of half the central angle.

  s = 2·sin(45°/2) ≈ 0.765367

The length of one side is about 0.77 units.

__

3) Similarly, the apothem is the cosine of half the central angle:

  a = cos(45°/2) ≈ 0.923880

The apothem is about 0.92 units.

__

4) For an octagon, the perimeter is 8 times the length of one side.

  P = 8s = 8(0.765367) ≈ 6.12293

The perimeter is about 6.12 units.

__

5) The area of one sector (isosceles triangle) is given by the formula ...

  A = (1/2)bh

  A = 1/2sa ≈ 1/2(0.765367)(0.923880) ≈ 0.353553

Then the area of the octagon is 8 times this:

  A = 8(sector area) = 8(0.353553) ≈ 2.82843

The octagon area is about 2.83 square units.

==============================================

Explanation:

The two factors are (a+b+c) and (d+e+f). A factor is a part of multiplication. So in general if we multiply x and y, then x and y are factors to lead to the product x*y.

The expression a+b+c has three terms. Each term is separated by a plus sign.

The expression d+e+f also has three terms.

Answer:

y - 18 = -1.5(x - 12)

Step-by-step explanation:

A = (12, 18)

B=(1.25(12), 0.75(18)) = (15, 13.5)

Find slope:  m = (13.5-18)/(15-12) = (-4.5)/3 = -1.5

Point slope form:  y - y1 = m(x - x1)

Using point A as (x1, y1)

y - 18 = -1.5(x - 12)

Answer:

1/10

Step-by-step explanation:

To convert a ratio to a fraction, you divide the number on the left by the number on the right. This gets you (3/5)/6. When dividing fractions by whole numbers, you need to convert the whole number to a fraction. I converted 6 to 6/1, so that gave me (3/5)/(6/1). You then multiply the top number by the bottom number to get the numerator of the answer, and the middle 2 numbers multiplied is the denominator. The answer is (3x1)/(5x6), or 3/30, which can be simplified to 1/10.

Answer:

Positive

Step-by-step explanation:

There are a couple ways we can go about this.

First, we can see that as x increases, so does y, so that means its positive

For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place

If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.

We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.

= 26+26 = 52

Choices for digits = 10

By Fundamental counting principle,

The different five character passwords can be created = (Choices for letters) x (Choices for digits)

= 52 x  10
