Answer:

(2, -1)

Step-by-step explanation:

5x + y = 9...........1

3x + 2y = 4.........2

from 1 y = 9 - 5x..........3

put eqn 3 in 2

3x + 2( 9 - 5x) = 4

3x + 18 - 10x =4

-7x = 4 - 18

-7x = -14

x = 14/7

x =2

put the value of x in equation 3

y = 9 - 5(2) = 9 -10 = -1

x = 2 and y = -1

Solve for x when 4x+16/12=x-4

stira [4]

Answer:

In short, Your Answer would be either 1 or 7

Step-by-step explanation:

|4x + 12| = 16

As it is in modulus function, it could be either +ve or -ve

4x+12 = 16 OR 4x - 12 = 16

4x = 16-12 OR 4x = 16 + 12

4x = 4 OR 4x = 28

x = 4/4 OR x = 28/4

Let P=x^2+6<br> PLEASE SHOW WORK!!<br> 15 POINTS

stellarik [79]

Answer:

Step-by-step explanation:

P = x^2 + 6

$(x^2+6)^2 - 21 = 4x^2 + 24\\(x^2+6)^2 - 4x^2 - 45 = 0$

Solving for 4x^2:

P = x^2 +6

P - 6 = x^2

4(P - 6) = 4x^2

Substitution:

$p^2 - 4p - 24 - 45 = 0\\p^2 -4p - 69 = 0$

blsea [12.9K]

Answer:

$1,448.66

Step-by-step explanation:

The future value of an annuity with yearly deposits 'P' at an interest rate of 'r' invested for 'n' years is determined by:

$FV = P[\frac{(1+r)^n-1}{r}]$

For P = $100, r = 0.08 and n = 10 years:

$FV = 100[\frac{(1+0.08)^{10}-1}{0.08}]\\FV=\$1,448.66$

The amount at the end of the ten years is $1,448.66
