Answer: (a) x = -1

Step-by-step explanation:

Given

x - 8 = - 9

Add 8 on both sides to isolate x

x - 8 + 8 = - 9 + 8

Answer: a= [tex]g+2 / 2[/tex]

Step-by-step explanation:

g= -2 + 2a

>> -2+2a=g ( side change )

>> -2+2a +2 = g+2 ( adding 2 both side)

>> 2a = g+2

>> 2a /2 = g+2 /2 ( divide by 2 both side)

>> a= g+2 /2

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.

If 1/8 of the total is 3, then the total is 3 multiplied by 8 = 24

        Another way:

Cross multiplication

12.5x =3x100(300)

There are 24 students in Ted's class.

Given that;

In Ted's class, students were asked to name their favourite sport.

And, Football was the response of 1/8 of them.

Let's assume the total number of students in the class is represented by "x".

According to the information given, 1/8 of the class said football, which means (1/8) × x students named football.

We also know that 3 students said football.

So, we can set up the equation:

(1/8) × x = 3

To solve for x, we can multiply both sides of the equation by 8:

x = 3 × 8

x = 24

Therefore, there are 24 students in Ted's class.

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

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

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

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.

There is a horizontal break (in the domain) at y=3, but no vertical break there. Hence the range is continuous through that region.
