Question 1.). Solve:

2 (x - 1 / 2) = 3 (5 - 2x)

Simplify both sides of equation:

2( x - 1 / 2 ) = 3(5 - 2x )

(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )


Distribute:

2x + - 1 = 15 + -6x

2x - 1 = -6x + 15


Add 6x to both sides:

2x - 1 + 6x = -6x + 15 + 6x

8x - 1 = 15


Add 1 to both sides:

8x - 1 + 1 = 15 + 1

8x = 16


Divide both sides by 8:

8x / 8 = 16 / 8

Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2











Question 2.).

M =======> Amount Malik need

Solution: =========> m ≥ 5

Inequality ========> 8 + 7 + 10 + m ≥ 30

25 + m ≥ 30

Interpretation ==========> Malik needs at least, $5 .00 to get to, $30.00 or more.

Is the solution reasonable ===========> YES





Hope that helps!!!!! : )

A powerful computer is purchased for $2000, but loses 20% of its value each year. How much will it be worth 4 years from now?
Jet001 [13]

Answer:

(A)Decay

(b)0.8

(c)First Term

(d)f(t)=2000(0.8)^t

(e)$819.20

Step-by-step explanation:

The exponential function for modelling growth or decay is given as:

A(t)=A_o(1\pm r)^t,

Where:

Plus indicates growth and minus indicates decay.

A_o$ is the Initial Value\\r is the growth/decay rate\\t is the time period

For a powerful computer that was purchased for $2000, but loses 20% of its value each year.

(a)Since it loses value, it is a decay.

(b)Multiplier

Its value decays by 20%.

Therefore, our multiplier(1-r) =(1-20&)=1-0.2

Multiplier =0.8

(c)$2000 is our First term (or Initial Value A_o)

(d)The function for this problem is therefore:

f(t)=f_o(1- r)^t\\f(t)=2000(1- 0.2)^t\\\\f(t)=2000(0.8)^t

(e)Since we require the worth of the computer after 4 years,

t=4 years

f(4)=2000(0.8)^4\\f(4)=\$819.20

DochEvi [55]

Answer:

(-2,3)

Step-by-step explanation:

Step 1. Isolate x for 3x + 5y = 9

3x + 5y - 5y = 9 - 5y

3x = 9 - 5y

3x/3 = 9/3 - 5y/3

x= (9-5y)/3

Step 2. Simplify

-3*((9-5y)/3) + 3y = 15

-3*((9-5y)/3) = 9 - 5y = -(-5 + 9) + 3y

-9+5y+3y

-9+8y = 15

Step 3 Isolate y for -9+8y=15

-9+8y+9=15+9

8y=24

8y/8 = 24/8

y=3

Step 4 Substitute y = 3

x = (9-5*3)/3

-(6/3) = (-2)

x = -2
