2x+y=8 simplify all fractions

Mrac [35]

The simplified form of the given equation ( 2x + y = 8 ) is x = 4 - y/2.

<h3>Simplify all fractions?</h3>

Give the equation;

2x + y = 8
Simplify

2x + y = 8

Subtract -y from both sides

2x + y - y = 8 - y

2x = 8 - y

Divide both sides by 2

2x/2 = ( 8 - y )/2

x = 8/2 - y/2

x = 4 - y/2

Therefore, the simplified form of the given equation ( 2x + y = 8 ) is x = 4 - y/2.

Write the slope intercept equation of a line that passes through points (-3,4) and (2, -6)

Setler [38]

Find slope by calculating rise over run.
-6-4 / 2-(-3)
-10/5
-2

Then plug one set of coordinates and the slope in to find the b value
-6= -2(2)+b
-6=-4+b
-2=b

Final answer: y=-2x-2

Suppose you invest $2250 in a D that earns 3% APR and is compounded monthly. The Cd matures in 2 years. How much will this CD be

olasank [31]

Answer:

$2388.95

Step-by-step explanation:

Principal, P= $2250
Annual Interest Rate, r= 3% =0.03
Time, n= 2 years
Since it is compounded monthly, Period, k= 12 Months

The worth of a compound deposit after a period of n years is calculated using the formula:

$A(n)=P(1+\frac{r}{k})^{nk}$

$A(2)=2250(1+\frac{0.03}{12})^{12 \times 2}\\\\=2250(1+0.0025)^{24}\\=2250(1.0025)^{24}\\=\$2388.95$

At maturity, the deposit will be worth $2388.95.
