8 0

Answer:

8,000 in the 8% account

20,000 in the 9% account.

Step-by-step explanation:

x + y = 28000

0.08 x + 0.09 y = 2440

0.08 x + 0.09 (28000 − x) = 2440

0.08 x + 2520 − 0.09 x = 2440

80 = 0.01 x

x = 8000

y = 20000

The first three steps of completing the square to solve the quadratic equation x2 +4x-6=0
hodyreva [135]

Answer:


Step-by-step explanation:

1.  Move the 6 to the other side:   x^2 +4x                        =6

2.  Square half the coefficient of the x term:  (4/2)^2 = 4

3.  Add this 4, and then subtract this 4, from x^2 + 4x:

     x^2 +4x + 4 - 4                       =6

4.  Rewrite this perfect square as the square of a binomial:

      (x + 2)^2   -   4   = 6

5.  Add 4 to both sides:    (x + 2)^2 =  10

6.  Find the sqrt of both sides:  x + 2 = √

Please help me with this question I will give brainliest.
Ainat [17]

Answer:

All you need to remember is the rules

Step-by-step explanation:

Let us remember

a to the m power x a to the nth power is = a to the m+n power. (add the exponents)

And

a to the m power ÷ a to the nth power is = a to the m-n power. (subtract the exponents) So

14 to the -4 power x 14 to the 7 power= 14 to the -4+7 which is equal to 14 to the 3rd power

Please help me solve this, I can't get a right answer even though it is easy: | 2x + 4 | = 12
Ket [755]
Because the left side is eclipsed in an absolute value, we have two possible values of x, denoted by:
2x+4 = 12 and -(2x+4) = 12

Solving for both of these, we are presented with the two values of x:
x = 4 and x = -8

Michael is 12 years older than Brandon. Seventeen years ago, Michael was 4 times as old as Brandon.
4vir4ik [10]

Answer:

21 yrs old

Step-by-step explanation:

m= michael age

b=Brandon age

m=b+12

m-17=4(b-17)= 4b-68 --»»m = 4b -51

//put b+12 instead m// b+12=4b-51

3b=63 --»»b=21

Brandon age is 21

Michael age is 33
