Answer:

x = -2

Step-by-step explanation:

7 - 48x - 42 = - 18x + 24 + 1

-35 - 48x = -18x + 25

-48x +18x = 25 =35

-30x = 60

x = -2

Answer:

-2

Step-by-step explanation:

7+6 (-8x-7)=3 (-6x+8)+1

7-48x-42= -18x+24+1

-48+18= 24+1-7+42

-30x=60 then divide the two sides with -30

x= -2

Answer:

A. An Algebraic Expression

Step-by-step explanation:

Since we have no equal sign in the problem, we know that it is an expression. An equation has an equal sign and another value so we can simplify to find the value of whatever variable we are working with. We also know that it is not anything numerical because we are working with variables. With this information we will see that the correct answer is A.

Answer:

Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.

Option B is the table which could represent the given situation.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

According to the question

A pool charges $7 for 2 daily pool passes.

Using the linear equation y = mx + b

Substitute x = 2, y = 7

[tex]7 = 2m + b[/tex].....(1)

Substitute x = 4, y = 14

[tex]14 = 4m + b[/tex]  .....(2)

Using elimination method

Subtract equation 1 from 2

[tex]14 - 7 = 4m - 2m + b - b[/tex]

[tex]7 = 2m[/tex]

[tex]m=\frac{7}{2}[/tex]

Substitute m = [tex]\frac{7}{2}[/tex] in equation 1

[tex]7=2(\frac{7}{2} )+b[/tex]

b = 7 - 7

b = 0

Substitute b = 0 in equation 1

7 = 2m

Similarly

14 = 4m

21 = 6m

28 = 8m

Hence, Option B is the table which could represent the given situation.

Answer:

a^6

Step-by-step explanation:

When the same numbers, the power can be just added together

For example

n x n x n =n^3 right?

Ya cuz when they don't put the power, it means to the power of 1

Therefore

a x a^2 x a^3

Just means

a ^ (1+2+3)

=a^6

Answer: a^6

Step-by-step explanation:

Term does not have an exponent so it’s automatically 1. So, a^1xa^2xa^3.

Multiply terms and add their exponents. So, a^1+2+3z

Add all exponents and you get 6. So, a^6

one x value cant go to two y values

Answer:

No....Not at all

You can select option A as the correct answer

Step-by-step explanation:

There can be two possibilities

From the definition of Function, We know, the value of a dependent variable corresponds to exactly one value of the independent variable

For possibility 1, For x = 5 and 9, y = 2 & for x = 5 and 7, y = 3

So this can't be a function

For possibility 2, For y = 3 and 2, x = 5

So this can't be a function

Answer:

$36

Step-by-step explanation:

The stock value of $40 increased by 20%.

Increased value

= 20% of $40

= (20/100) × $40

= $800/100

= $8

New stock value

= Initial value + increased value

= $40 + $8

= $48

Then, the value decreased by 25%.

Decreased value

= 25% of $48

= (25/100) × $48

= $1200/100

= $12

New stock value

= Initial value + decreased value

= $48 - $12

= $36

So, the resulting stock value is $36.

Answer:

The resulting value of the stock is $36.

Step-by-step explanation:

First, we need to find out what 20% of $40 is.

40 x 0.20 = 8

40 + 2 = $48

Therefore, the stock value, when increased, is $48.

Now, we need to see what 25% of $48 is.

48 x 0.25 = 12

48 - 12 = $36

Therefore, the resulting value of the stock is $36.
