Jonathan has been on a diet since January 2013. So far, he has been losing weight at a steady rate. Bases on monthly weigh-ins, his weight, w, can be modeled by the function w=-3m+205 where m is the number of months after January 2013.a) How much did Jonathan weight at the start of the diet?

b) How much weight has Jonathan been losing each month?

c) How many months did it take Jonathan to lose 45 pounds?

Evaluate f(x) = X(With an exponent of 2) -3x +2, given f(x + 1).

Answers

Answer:

f(x + 1) = x² - x

Step-by-step explanation:

f(x) = x² - 3x + 2 when f(x + 1)

f(x + 1) = (x + 1)² - 3(x + 1) + 2

f(x + 1) = (x² + 2x + 1) + (-3x - 3) + 2

f(x + 1) = x² - x + 0

f(x + 1) = x² - x

The work of a student to solve a set of equations is shown below:Equation 1: m = 8 + 2n
Equation 2: 4m = 4 + 4n

Step 1: −4(m) = −4(8 + 2n)
4m = 4 + 4n

Step 2: −4m = −32 − 8n
4m = 4 + 4n

Step 3: −4m + 4m = −32 − 8n + 4n

Step 4: 0 = −32 − 4n

Step 5: n = − 8

In which step did the student first make an error?
Step 1 Step 2 Step 3 Step 4

Answers

The error is found in step 3.

Here is what he did:

-4m + 4m = -32 - 8n + 4n <<<<<<<<<<<< What happened to +4???

0 = -32 - 4n

n = -8.

He made erron in step 3. He forgot add 4. it should be
-4m + 4m = -32 - 8n + 4n +4
