Answer:

x = 2  +  √-16 [ (-2)⁻¹]

See steps below.

Step-by-step explanation:

Finding the zeroes of a function simply means solving for the unknown variable (in this case "x") when the function is equated to zero.

The function here is   [tex]f(x) = -(x + 1)^{2} - 4 = 0[/tex]

Start by opening the bracket. Ignore the minus sign. It will be reintroduced at the end of this step.

(x + 1)(x + 1)   = x² + x + x + 1    = x² + 2x + 1

Reintroduce the minus sign. Don't forget to put the result above back in a bracket.

- (x² + 2x + 1)  = -x² -2x -1

Place the expression back in the equation and solve. Make sure to put it back in the position where it was.

-x² - 2x - 1 - 4 = 0

Simplify the non-algebraic terms.

-x² - 2x - 5 = 0

Use Quadratic Formula to solve for x.

Quadratic formula: x =  -b ± √(b² - 4ac)

                                              2a

a = the coefficient of x² = -1

b = the coefficient of x  = -2

c = the unit term            = -5

So   x = -(-2)  ± √ [(-2)² - 4(-1 x -5)]

                       2(-1)

x = 2 + √-16                    or x = 2 - √-16

         -2                                          -2

This is where the evaluation ends, since the square root of minus sixteen cannot be evaluated. x hence is equal to a complex number. The above are the two values for x.

Next step is to put it in "a + bi" form.

x = 2  +  √-16  ÷  -2     =  2  +  √-16  x (-2)⁻¹

So   x = 2  +  √-16 [ (-2)⁻¹]

where

a is 2;

b is √-16

i is [(-2)⁻¹]

Answer:

The slope is -4

Step-by-step explanation:

Answer: -4

-4 is the slope because in the equation y=mx+b, m represents the slope.

Answer:

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.

3) O(x,y)=(x-3,y+5)

The rule that describes the translation is (x, y) -> (x - 3, y + 5), the correct option is C.

The transformation of a function may involve any change.

Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.

If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:

y=f(x+c) (same output, but c units earlier)

Right shift by c units:

y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y =[tex]k \times f(x)[/tex]

Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]

We are given that;

5 units up and 3 units to the left

Now,

In this case, the rectangle is translated 5 units up and 3 units to the left. This means that the vertical shift is 5 and the horizontal shift is -3.

After transformation x=x - 3

Y=y + 5

Therefore, the transforming function will be (x, y) -> (x - 3, y + 5).

Answer:

Step-by-step explanation:

the pot will be a cylinder,

V=3.14*r^2*h

V=3.14*(4.5)^2*7.5=476.89

The volume of the soup pot is equal to 476.89 cubic inches.

Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube and for the cone it will be radius and height.

The space occupied by the cylinder in three-dimensional space is called the volume of the cylinder.

Given that the soup pot is 7.5 inches tall with a radius of 4.5 inches. The volume of the soup pot will be calculated as,

V=3.14 x r² x h

V=3.14 x (4.5)² x 7.5

V =476.89 cubic inches

Answer:

A=$2100

B=$1400

Step-by-step explanation:

3500*1.06=3710

a+b=3500

1.05a+1.075b=3710

1.05a+1.05b=3675

1.05a+1.075b=3710

Subtract 1.05a+1.05b=3675 from 1.05a+1.075b=3710

0.025b=35

b=1400

a=3500-1400=2100

Double check: (2100*1.05)+(1400*1.075)=3710

3500*1.06=3710

The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

0.05a + 0.075b = (0.06 x $3500)

0.05a + 0.075b = $210 ----- equation 1

a + b = $3,500   -------- equation 2

Where:

a is the amount invested in the account that paid a 5% interest.

b is the amount invested in the account that paid a 7.5% interest.

The amount invested in the account that pays a 7.5% interest.

In order to determine this value, multiply equation 2 by 0.05

0.05a + 0.05b = 175  ------- equation 3

0.025b = 35

b = $1400

The amount invested in the account that pays a 5% interest.

a + $1400 = $3500

a = $3500 - 1400

a = $2100

Therefore, The amount invested in the account that pays a 5% interest is $2100 and the amount invested in the account that pays a 7.5% interest is $1400.

Answer:

Year 2022

Step-by-step explanation:

Let number of years = x

Samantha :

Bonus + yearly earning

50 + 5x

Emily :

40 + 10x

Curent earning in 2018:

Years worked by Samantha = 6

50 + 5(6) = 50 + 30 = 80

Years worked by Emily = 2

40 + 10(2) = 60

Year when they'll both receive same amount :

80 + 5x = 60 + 10x

5x - 10x = 60 - 80

-5x = - 20

x = 20/5

x = 4 ; x = 4 years

Answer:

Please check the explanation.

Step-by-step explanation:

Given the system of equations

2 + 2y = 6

2x - 3y = 26

Let us solve the system of equations

[tex]\begin{bmatrix}2+2y=6\\ 2x-3y=26\end{bmatrix}[/tex]

Rearrange equations

[tex]\begin{bmatrix}-3y+2x=26\\ 2y=4\end{bmatrix}[/tex]

Multiply -3y+2x=26 by 2:    -6y+4x=52

Multiply 2y = 4 by 3:  6y = 12

[tex]\begin{bmatrix}-6y+4x=52\\ 6y=12\end{bmatrix}[/tex]

adding the equations

[tex]6y=12[/tex]

[tex]+[/tex]

[tex]\underline{-6y+4x=52}[/tex]

[tex]4x=64[/tex]

Solve 4x = 64 for x

[tex]4x = 64[/tex]

divide both sides by 4

[tex]\frac{4x}{4}=\frac{64}{4}[/tex]

Simplify

[tex]x = 16[/tex]

For -6y+4x = 52 plug in x = 16

[tex]-6y+4\cdot \:16=52[/tex]

Multiply the numbers: 4 · 16 = 64

[tex]-6y+64=52[/tex]

Subtract 64 from both sides

[tex]-6y+64-64=52-64[/tex]

Simplify

[tex]-6y=-12[/tex]

Divide both sides by -6

[tex]\frac{-6y}{-6}=\frac{-12}{-6}[/tex]

[tex]y=2[/tex]

Therefore, the solution to the system of equations be:

[tex]y=2,\:x=16[/tex]

Thus,

(x, y) = (16, 2)

Answer:

[tex](a):\ y = \frac{x + 3}{7}[/tex] --- Function

[tex](b):[/tex] Not a function

[tex](c):[/tex] A function

Step-by-step explanation:

Given

See attachment

Required

Determine if each relation is a relation or not

A function is represented as: [tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3)...(x_n,y_n)\}[/tex]

Where

[tex]x = domain[/tex] and [tex]y = range[/tex]

For a relation to be a function:

No x value (in other words, the domain) must be repeated

[tex](a):\ y = \frac{x + 3}{7}[/tex]

The above relation is a function. This is so because every unique value of x have a unique value of y.

In other words:

No two domains exist for a range

Conclusively, it is a one-to-one function

[tex](b):[/tex]

[tex]\begin{array}{ccccc}x & {-2} & {-2} & {1} & {3} \ \\ y & {-5} & {-1} & {3} & {7} \ \ \end{array}[/tex]

In the above table, we have:

[tex](x_1,y_1) = (-2,5)[/tex] and [tex](x_2,y_2) = (-2,-1)[/tex]

The domain (-2) points to range (5 and -1).

Based on the condition that no two domain should point to the same range, we can conclude that this is not a function.

[tex](c):[/tex]

[tex]\begin{array}{ccccc}x & {-3} & {-1} & {1} & {3} \ \\ y & {-4} & {-4} & {2} & {2} \ \ \end{array}[/tex]

In the above table, we have the domain to be:

[tex]x = \{-3,-1,1,3\}[/tex]

We can see that no x value is repeated.

Hence, this is a function.
