Answer:

6.08 x [tex]10^{-7}[/tex]

Step-by-step explanation:

For scientific notation, you want one digit to be in front of the decimal point -- so you need to move the decimal point 7 spaces to the right -- which is the same as dividing by 10^7, or multiplying by 10^(-7).  So you're left with 6.08 x 10^(-7)

Step-by-step explanation:

Step one:

given data

total distance= 450 miles

time take= 9 hours

Tom's average speed= 450/9

= 50 miles per hours

Tammy's average speed= 450/7.5

= 60 miles per hours

Answer:

f(2) = -2

Step-by-step explanation:

Replace y with f(x). The equation is now f(x) = 3x - 8. f(2) means that you replace all of the x’s with 2’s. Bringing the equation to f(2) = 3(2) - 8. You now just have to solve the equation. f(2) = 6 - 8. f(2) = -2

Answer:

1)  Try a = 23/2. With this value, equation 1 multiplied by 2 is exactly the same as equation 2.

2) Try dividing 2005/3 + 2005/4 - 2005/6. Ignore the fractional parts.

3) If you are allowed to repeat the letters, then you should have: 3^3 = 27

Answer:

a = 8

Step-by-step explanation:

For the 2 equations to have infinite solutions we require the solution to be in the form

0 = 0

Given

2x + 5y = - 8 → (1)

6x = 16 + a - 15y ( add 15y to both sides )

6x + 15y = 16 + a → (2)

Multiply (1) by - 3

- 6x - 15y = - 24 → (3)

Adding (2) and (3) term by term gives

0 + 0 = 16 + a - 24

For the right side to be zero , then

16 + a =  24 ( subtract 16 from both sides )

a = 8

take the value in that BIG curly bracket as X terms....then substitute one by one to the equation given below to get Y values...after that u have cordinates then u can draw the graph..

[tex]x \: \: \: y \\ - 2 = - 8 \\ - 1 = - 10 \\ 0 = - 12 \\ 1 = - 14 \\ 2 = - 16[/tex]

this is for the first equation..so the coordinated are...

(-2,-8), (-1,-10), (0,-12), (1,-14), (2,-16)

Answer:

5+8y

Step-by-step explanation:

combine like terms (3y+5y)

Answer:

Step-by-step explanation:

Given the expression;

4x/3x+1 = x/2x+10

We are to get the nature of the value of x

Cross multiply;

x(3x+1) = 4x(2x+10)

3x²+x = 8x²+40x

Collect like terms;

3x²-8x² + x - 40x = 0

-5x²+x -40x = 0

-5x²-39x = 0

-5x² = 39x

-5x = 39

x = -39/5

Since we have just one value of x hence, the equation has one valid solution and no extraneous of solutions.

The equation has one valid solution and no extraneous of solutions. The correct option is A.

An equation is a mathematical expression in terms of one or more unknown variable.

Given the equation : 4x/3x+1 = x/2x+10

Simplify by Cross multiplication, we get

x(3x+1) = 4x(2x+10)

3x²+x = 8x²+40x

3x²-8x² + x - 40x = 0

-5x²+x -40x = 0

-5x²-39x = 0

Simplifying further and solving for x

-5x² = 39x

-5x = 39

x = -39/5

We have just one value of x.

Hence, the equation has one valid solution and no extraneous of solutions.

Answer:

she would need to work at least 13 hours lifeguarding to get to the 290 her with the of working an extra 3 hours  

Step-by-step explanation:

subtract the 30 dollars from babysitting from the 290 needed you 260 then divide it by 20

The minimum number of whole hours lifeguarding that she must work to meet her requirements will be 14 hours.

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Annabelle is working two summer jobs, making $10 per hour babysitting and making $20 per hour lifeguarding.

In a given week, she can work no more than 19 total hours and must earn no less than $290.

Now,

Let x represents the number of hour for babysitting, and 'y' represents the number of hours for lifeguarding.

Since, In a given week, she can work no more than 19 total hours and must earn no less than $290.

Hence, We can formulate;

⇒ x + y < 19

And, 10x + 20y > 290

So, For Annabelle worked 3 hours babysitting, the minimum number of whole hours lifeguarding is,

⇒ 3 + y < 19

⇒ y < 16

And, 10x + 20y > 290

⇒ 30 + 20y > 290

⇒20y > 290 - 30

⇒ 20y > 260

⇒ y > 13

Thus, The possible value of y = 14, 15

So, The minimum number of whole hours lifeguarding that she must work to meet her requirements will be 14 hours.
