Evaluate 2+3y when y=8

If J represents John's age, then J + 15 = 3(J - 1) equations could be used to solve the problem

What is Equation?

Two or more expressions with an equal sign is called as Equation.

Given that

"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John.

F=Frank

J=John

S=Sue.

I am 15 years older than John

In the sense Frankes age is 15 more than John age, So it is 15+J

Sue is 1 year younger than John.

So Sue's age is less than john

J-1

"I am 3 times as old as Sue is"

Three times of J-1

3(J-1)

So equating this we get

Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.

15+J=3(J-1)

Hence 15+J=3(J-1) is the equation could be used to solve the problem.

#SPJ5

Frank = F

Sue = S

John = J

F=3*S

F = J+15

S = J-1

If you want to find Frank's age, then his age would be equivalent to John's plus 15 years.

A.-Would not work because Frank is three times Sue's age, not John's (left hand side of the equation).

B.-Notice that the right hand side of the equation is equivalent to Sue's age, which we know is John-1, however it is currently written to be "three times Sue's age minus one" which would give us John's age, plus two more years than his actual age on the left hand side.

C.-Frank's age is equal to John's plus fifteen (right side of the equation) and Frank is equal to Sue's age times 3. But, if Sue is in terms of Johns, then Sue's age is John's minus one. Therefore, Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.

Therefore C is the answer. C:

Options:

1. Yes; everyone who doesn't exercise is by definition unhealthy.
2. Yes; the correlation coefficient is above 0.5, so that implies causation.
3. No; the data doesn't suggest a causation, and many people are healthy who don't exercise.
4. No; poor health and not exercising are completely unrelated.

The answer is the third option "No; the data doesn't suggest a causation, and many people are healthy who don't exercise." Correlation is two data set that are linked or connected together so in this case it would be a correlation because all of the data is close and connected to each other.

Hope this helps!

Answer:

No; the data doesn't suggest a causation, and many people are healthy who don't exercise

Step-by-step explanation:

I took the quiz and this was the answer.

Answer:

No, Isiah is not correct. The GCF of the coefficients is 1, and there are no common variables among all three terms of the polynomial. 5b4 is a factor of -25a2b5 and -35b4, but not a3. Additionally, a2 is a factor of a3 and -25a2b5, but not -35b4. 1 is the GCF of the coefficients. There are no common variables among all three terms of the polynomial.  5b4 is the GCF of –25a2b5 and –35b4, but not a3.  a2 is a factor of a3 and – 25a2b5, but not –35b4.

Considering the multiplciation of the GCF of the numeric terms and of the variables, the GCF of the polynomial is of 1, hence he is not correct.

What is the greatest common factor of a polynomial?

It is the multiplication of the GCF of the numeric constants by the GCF of the coefficients.

In this problem:

• The coefficients of a are 3, 2 and 0, hence the GCF is .

• The coefficients of b are 0, 5 and 4, hence the GCF is .

• As for the numeric term, the terms are 1, 25 and 35, hence the GCF is 1.

Thus:

As Isaiah did not take into account the coefficients that are zero, his calculation is not correct.
