Answer:

The equation would be p=-3

Step-by-step explanation:

First of all, you must take into account that all the terms with the letter p must be on the left side of the equation, the other terms must be on the right side.

First step

The 4p term must be passed to the left with opposite sign

5p+2-4p=-1

Second step

The +2 term from the left must be passed to the right with opposite sign

5p-4p=-1-2

Third step

You must perform the operations. The equation would be:

p=-3

Thus, the equation would be p=-3

Mary has $65,000 to invest in two accounts. The first account is a private savings offering 6% annual interest and the second ac
const2013 [10]

Answer:

first account with 6% interest ( x ) = $46000

second account with 4% interest ( y ) = $19000

Step-by-step explanation:

Principal = $65000

first interest rate = 6%

second interest rate = 4%

assuming ; X = money invested in first account ,  Y = money invested in second account

hence :

( 65000 - y ) * 6% + ( 65000 - x ) * 4% = 3520

3900 - 0.06 y  + 2600 - 0.04 x = 3520

0.04 x + 0.06 y = 3900 + 2600 - 3520

0.04 x + 0.06 y = 2980 ----- ( 1)

        x + y = 65000  ------- ( 2 )

solve equation 1 and 2 simultaneously by elimination method

0.04 x + 0.06 y = 2980 ------  ( 3 )

0.06 x + 0.06 y = 3900 ------- ( 4 )

subtract equation 3 form equation 4

0.02 x  = 920 ,   hence x = $46000

therefore y = $65000 - $46000 =  $19000

What is the value of f(-4)?
Ghella [55]

Given is a piecewise function which follows different expressions according the the value of input x.

Given f(x)=\left \{ {{-10, \;if \;x2} } \right.

It says to find f(-4) i.e. the value of function f(x) at x = -4.

At point x = -4, f(x) is x³, if -5 ≤ x ≤ 2.

So, f(-4) = (-4)³

f(-4) = -4 × -4 × -4

f(-4) = -64.

Hence, option A is correct i.e. -64.
