Answer:

The result is 8.75 x10^8

Step-by-step explanation:

When you multiply numbers in scientific notation, you do the following:  

Multiply the base numbers normally:  

2.5* 3.5 = 8.75  

The exponents with base 10 are added and the base stays the same in the result:  

10^10x10^-2= 10^(10+(-2))=10^8.  

The answer is the multiplicaton of both 8.75*10^8.

What it is basically asking is if Y = -4, find the value of x in the equation 6x + 7y = 4x + 4y

To solve this you just need to plug in -4 for y and solve for x

6x + 7(-4) = 4x + 4(-4)

6x - 28 = 4x - 16

Now isolate x by adding 28 to both sides

6x - 28 + 28 = 4x - 16 + 28

6x = 4x + 8

and subtract 4x from both sides

6x - 4x = 4x - 4x + 8

2x = 8

divide both sides by 2

2/2x = 8/2

x = 4

x = 4, y = -2

Answer: (4, - 2)

Hope it helps :)

Bransliest would be appreciated

After 9 months, the simple interest earned on an investment of $1200 is $72. find the interest rate.
Deffense [45]
Use the formula i=prt, where i is the interest earned, p is the principal, r is the rate (as a decimal fraction) and t is the elapsed time, in years.

Here i = $72 = $1200 r (9/12)                    (9 months is 9/12, or 3/4, of 1 year)
Reducing, 
              $72 = $900r
                                          Solving for r, r=0.08, or 8 percent per year.
