Answer:

1 foot above the ground, positive 1

Step-by-step explanation:

you start at ground level let's call that 0

you go 10 down 0-10=-10

Now you climb up 20 feet so -10+20=10

Then you finally climb down 9 feet and 10-9=1

So you are one foot above the ground.

[tex]\frac{1}{4}z=-\frac{7}{8}+\frac{1}{8}z[/tex]

subtrac (1/4)z in both sides

[tex]\begin{gathered} \frac{1}{4}z=-\frac{7}{8}+\frac{1}{8}z \\ \frac{1}{4}z-\frac{1}{4}z=-\frac{7}{8}+\frac{1}{8}z-\frac{1}{4}z \\ 0=-\frac{7}{8}-\frac{1}{8}z \end{gathered}[/tex]

Step 2

add 7/8 in both sides

[tex]\begin{gathered} 0=-\frac{7}{8}-\frac{1}{8}z \\ 0+\frac{7}{8}=-\frac{7}{8}-\frac{1}{8}z+\frac{7}{8} \\ \frac{7}{8}=-\frac{1}{8}z \\ \end{gathered}[/tex]

finally, multiply both sides by -8 in order to isolate z

[tex]\begin{gathered} \frac{7}{8}=-\frac{1}{8}z \\ \frac{7}{8}*-8=-\frac{1}{8}z*-8 \\ -7=z \end{gathered}[/tex]

therefore, the answer is

-7

Answer: Choice A

x^2-12x+36; is a polynomial

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

Explanation:

Use the rule that (A-B)^2 = A^2 - 2AB + B^2 to show (x-6)^2 = x^2-12x+36 is an identity. In this case, A = x and B = 6

You could also use the FOIL rule or the distributive property as two alternatives.

The result is a polynomial because it consists of summing or subtracting various monomials. If we had terms that had say exponents of decimal numbers or negative values, then we wouldn't have a polynomial.

Let be "x" Jon's current salary.

According to the information given in the exercise, the salary at the new job is 68,000 and this is 12% more than his salary at his current job.

To convert from percent to a Decimal number, you can divide by 100. Then:

[tex]\frac{12}{100}=0.12[/tex]

Therefore, knowing that information, you can set up the following equation:

[tex]x+0.12x=68,000[/tex]

Now you can solve for "x" in order to find its value:

Answer:

Yes, 21.23 is a rational number.

[tex]21.23=\dfrac{2123}{100}[/tex]

Step-by-step explanation:

Terminating decimal numbers are decimals that have a finite number of decimal places.

A Rational Number is the division of an integer by another integer.

Therefore, 21.23 is a terminating decimal since it has a finite number of decimal places.

Let x be the rational number.

[tex]\implies x=21.23[/tex]

Multiply both sides by 100 so that the right side is an integer:

[tex]\implies 100x=2123[/tex]

Divide both sides by 100:

[tex]\implies x=\dfrac{2123}{100}[/tex]

(This fraction cannot be reduced any further).

Therefore, we have proved that 21.23 is a rational number.

Answer:

It is a rational number.

Step-by-step explanation:

Given value,

→ 21.23

Converting into rational number,

→ (21.23/1) × (100/100)

→ (21.23 × 100)/(1 × 100)

→ 2123/100

Hence, it is a rational number.

ANSWER

A. True

EXPLANATION

Let the complex number be z = a+ ib, so its complex conjugate is z* = a - ib, where a and b are real numbers. Let's find the product,

The product is,

[tex](a+ib)(a-ib)=a\cdot a-a\operatorname{\cdot}ib+ib\operatorname{\cdot}a-ib\operatorname{\cdot}ib[/tex]

Solve the products,

[tex](a+ib)(a-ib)=a^2-iab+iab-i^2b^2[/tex]

Simplify: note that the second and third terms are opposites, so they cancel out. Remember that i² is equal to -1,

[tex](a+ib)(a-ib)=a^2+0-(-1)b^2=a^2+b^2[/tex]

Since a and b were real numbers, then the sum of their squares is also a real number.

Hence, this statement is true.

3x+2y=10 This is the equation of the new line in standard form

Calculate the equation of the line in standard form?

Two parallel lines have the same slope, to compute the slope (m) of the equation 3x+2y=19. This can be obtained by converting the equation into slope-intercept form (i.e., y=mx+b, where m is the slope):

by subtracting 3x from both sides, and then simplifying:

3x+2y-3x=19-3x

2y =-3x+19

Then, let's divide both sides by 2, to obtain slope-intercept form:

y = (-3/2)x+(/2) From this, we know that the slope (m) is -3/2

To determine the equation of the line we're being asked to solve for. If we know the slope (in this case m=-3/2) along with any given point on the line ((x0,y0); in this case (4,1)), the equation of the line can be determined as y-y0=m(x-x0)

So substituting, the equation of the line is y-1=(-3/2)(x-5)

We now need to put this into standard form, with both x and y terms on the left side of the equation:

First, distribute the 3/2 on the right side: y-1=(-3/2)x+(3/2)5 or y-1

= (-3/2)x+6

Next, add (3/2)x to both sides, add 1 to both sides, and simplify:

(3/2) x + y = 5

multiply both sides by 2, to eliminate the fraction (3/2): 3x+2y = 10 This is the equation of the new line in standard form

Kira have $23 in his wallet.

Justin have $13 in his wallet.

Reuben have $46 in his wallet.

Given,

There are three persons, Kira, Justin, Reuben.

The total amount in their wallet = $82

The amount in Justin's wallet = x

The amount in Kira's wallet = x + 10

The amount in Reuben's wallet = 2(x + 10)

We have to find the amount in their wallets.

Here,

x + x + 10 + 2(x + 10) = 82

2x + 10 + 2x + 20 = 82

4x + 30 = 82

4x = 82 - 30

x = 52/4 = 13

Now,

The amount in Justin's wallet = x = $13

The amount in Kira's wallet = x + 10 = 13 + 10 = $23

The amount in Reuben's wallet = 2(x + 10) = 2(13 + 10) = 2 × 23 = $46

[tex]\begin{gathered} \text{Domain: -7 }\leq x\leq3 \\ \text{Range: }-1\text{ }\leq y\leq9 \end{gathered}[/tex]

EXPLANATION

We want to find the domain and range of the function.

The domain of a function is the set of all input values of the function. Basically, the set of all x values of a function.

The range of a function is the set of all output values of the function. Basicallly, the set of all y values of a function.

To find the domain of the function, we have to look at the smallest and largest values of x.

The smallest value of x is -7.

The largest value of x is 3.

So, the domain is:

[tex]-7\text{ }\leq x\text{ }\leq3[/tex]

To find the range of the function, we have to look at the smallest and largest values of y.

The smallest value of y is -1.

The largest value of y is 9.

So, the range is:

[tex]-1\text{ }\leq y\leq9[/tex]

Applying the quotient rule, the derivative of the given function at x = 3 is of -2/3.

What is the quotient derivative rule?

A quotient function is defined as follows:

i(x) = g(x)/f(x)

Applying the quotient rule, the derivative of the function defined above is of:

i'(x) = [g'(x)f(x) - f'(x)g(x)]/f(x)².

Hence, at x = 3, the numeric value of the derivative is given as follows:

i'(3) = [g'(3)f(3) - f'(3)g(3)]/f(3)².

Function f(x) is a linear function with slope of -3/2, hence:

f'(3) = -3/2 (for a linear function, the derivative is constant).f(3) = 3/2 (from the graph).

Function g(x) is a linear function with slope of -1/2, hence:

g'(3) = -1/2.g(3) = 1/2.

Then the derivative is given as follows:

[tex]g^{\prime}(3) = \frac{-\frac{1}{2} \times \frac{3}{2} - \frac{3}{2} \times \frac{1}{2}}{\left(\frac{3}{2}\right)^2} = -\frac{\frac{6}{4}}{\frac{9}{4}} = -\frac{6}{9} = -\frac{2}{3}[/tex]
