e(x) = -x + 1
Find e(-1)

Answer:

C is the answer

Answer:

1

Step-by-step explanation:

First, we have to make the fractions improper.

To this we would need to multiply the denominator by the whole number and add it to the numerator. 2*4 is 8.  8 + 5 is 13. So for the first fraction, it will be 13/5. Let’s do the second fraction. 2*4 is 8. 8 + 3 is 11. So for the second fraction, it will be 11/2. Since the fractions have the same denominator, we will not have to do anything to them. Now, all you have to do is simple subtraction. 13 - 11 is 2. Since the denominators are the same, it will equal to 2. So the final answer is 2/2 or 1.

Answer:

8, 2, 4

Step-by-step explanation:

All the y values of a function are its range and all the x values are its domain

Since the y values of the functions are 8, 2, and -4. the range of this function{(4,8), (9,2), (-3,-4)} will be 8, 2, -4.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

All the y values of a function are its range and all the x values are its domain

All y's potential values are referred to as the function's range. Using the formula y = f(x), one may determine a function's range (x). If there is just one y value for each x value in a relation, then it is merely a function.

The y values of the functions are 8, 2, and -4.

Thus, since the y values of the functions are 8, 2, and -4. the ranges of this function{(4,8), (9,2), (-3,-4)} will be 8, 2, -4.

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene triangle, obtuse triangle, equilateral triangle and right angled triangle.

Trigonometric functions are functions used to show the relationship between an angle of a right-angled triangle and the ratio of two side lengths. Below are some trigonometric function:

sinθ = opposite/hypotenuse, cosθ = adjacent/hypotenuse, tanθ = opposite/adjacent.

Given the right angled triangle with angle x. and the hypotenuse y. We need to find the distance between the Earth and the shooting star.

d = distance between the Earth and the shooting star = adjacent side.

Therefore, the relationship between angle x, d and y can be gotten using the cos trig function.

cosθ = adjacent / hypotenuse

cos(x) = d / y

d = y * cos(x)

The value of x from the given equation is -2.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is 4(x - 2) + 3 = 2x - 9.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

4x-8+3=2x-9

4x-5=2x-9

4x-2x=-9+5

2x=-4

x=-2

Therefore, the value of x from the given equation is -2.

Answer:

Length of rectangular patio = 28 feet

Step-by-step explanation:

Given that:

Length of rectangular patio = x

Width of rectangular patio = [tex]2x-40\frac{3}{4}[/tex]

Perimeter of rectangular patio = [tex]86\frac{1}{2}[/tex]

Perimeter of rectangular patio = 2 (length + width )

Putting values in the formula

[tex]86\frac{1}{2}=2(x+2x-40\frac{3}{4})\\\\\frac{173}{2}=2(3x-\frac{163}{4})\\\\\frac{173}{2}=2(\frac{12x-163}{4})\\\\\frac{173}{2}=\frac{12x-163}{2}\\\\173 = 12x-163\\12x = 173 + 163 \\12x = 336[/tex]

Dividing both sides by 12

[tex]\frac{12x}{12}=\frac{336}{12}\\x=28[/tex]

Hence,

Length of rectangular patio = 28 feet

Step-by-step explanation:

Step one:

Given data

A candle that is 10 inches tall burns at a rate of 1/4 inches per hour

let the number of hours take to burn completely be x

and the lenght after certain time be y

So

The expression for the situation is

y= 10-1/4x

y= 10-0.25x

for x= 12

y=10-0.25*12

y=10-3

y= 7 in

After 12 hours the length is 7 in

Answer:

Step-by-step explanation:

2(x + 15)⁰ + (3x + 20)⁰=180⁰

2x + 30⁰ + 3x + 20⁰=180⁰

2x + 3x + 30⁰ + 20⁰=180⁰

5x + 50⁰ - 50⁰=180⁰-50⁰

5x=130⁰

5x/5=130⁰/5

x=26⁰

Answer:

x should equal 26.

Step-by-step explanation:

since they are cointerior angles:

2 (x + 15) + (3x + 20) = 180

2 (x) + 2 (15) + (3x + 20) = 180

2x + 30 + (3x + 20) = 180

2x + 30 + 3x + 20 = 180

5x + 50 = 180

5x + 50 - 50 = 180 - 50

5x = 130

5 ÷ 5x = 130 ÷ 5

x = 26
