Answer:

Option B) The simplification performed in step 2 is invalid or incorrect

The value of w in the given expression is -54

Step-by-step explanation:

Option B) The simplification performed in step 2 is invalid or incorrect

The corrected steps are given below :

GIven expression is w+xy+3x^2=2 and x=2y

To find w when y=-2 :

Step 1: I first substitute y=-2 into x=2y yielding x=2(-2)

Step2: I simplify the expression resulting in x=-4

Step3: I substitute x=-4 and y=-2 into the given expression w+xy+3x^2=2 we get

w+(-4)(-2)+3(-4)^2=2

Step 4: I use order of operations to simplify and get

w+8+3(16)=2

w=2-56

Therefore w=-54

The value of w in the given expression is -54

Find the simple interest earned to the nearest cent for each principal, interest rate, and time.
Y_Kistochka [10]

Answer:

Interest earned at 3.9 percent rate is $31.2

Interest earned at 2 percent rate is $5.8

Step-by-step explanation:

A = P(1 + rt)

Where 'A' is the amount, 'r' is the rate and 't' is the time in years

When;

P = $1200

r = 3.9%

t = \frac{8}{12} years

Then,

A = $1200(1 + 0.039(\frac{8}{12}))

A = $1200 + $31.2 = $1231.2

Interest = Amount - Principal

Interest earned at 3.9 percent rate is $1231.2 - $1200 = $31.2

When;

P = $580

r = 2%

t = \frac{6}{12} years

Then,

A = $580(1 + 0.02(\frac{6}{12}))

A = $580 + $5.8 = $585.8

Interest earned = Amount - Principal

Interest earned at 2 percent rate = $585.8 - $580 = $5.8
