The answer I got was 21 because 6x3=18 5x2=10 3-4=-1 and -1x3=-3
-3 x 2=-6 and the +2 so you would have
18+10+-3+-6+2
28+. -3+-6+2
25+-6+2

How to get everything to one side of the inequality for 3+4/x&gt;=(x+2)/x
Ksenya-84 [330]

Answer:

2x+2\geq 0

Step-by-step explanation:

Given:

The given inequality is.

3+\frac{4}{x} \geq \frac{x+2}{x}

Solution:

Simplify the given expression.

3+\frac{4}{x} \geq \frac{x+2}{x}

Multiply by x both side of the equation.

x(3+\frac{4}{x}) \geq x(\frac{x+2}{x})

Simplify.

3x+\frac{4x}{x} \geq x(\frac{x+2}{x})

3x+4\geq x+2

Rewrite the equation as.

3x+4-x-2\geq 0

2x+2\geq 0

Therefore, 2x+2\geq 0 is the simplest form of the given expression.

Can someone help me please?? in Algblra2 - Variations, Progression, and Theorems
VashaNatasha [74]
If (y-1) is a factor of f(y), f(y)=0 when y=1.  So if you find that f(1)=0, then (y-1) is a factor of f(y).

f(y)=y^3-9y^2+10y+5

f(1)=1-9+10+5=7

Since f(1)=7, (y-1) is not a factor.

Alex invests his money in an account paying 2% interest compounded semiannually. What is the effective annual yield on this acco
Travka [436]

Answer: 2.01%.

Step-by-step explanation:

Suppose Alex invests $1 into the account for one year. The formula is A=P0⋅(1+rk)N⋅k with P0=$1. We know that r=0.02 and k=2 compounding periods per year. Now, N=1 year. Substituting the values we have A=$1⋅(1+0.022)2=$1.0201. Now, to calculate the effective annual yield, we will use the formula rEFF=A−P0P0. rEFF=1.0201−11=0.0201 or 2.01%. When rounded to two decimals, rEFF=2.01%. However, do not include the % in your answer.
