3. If a and b are positive integers such that a+b=9, then what is the value of b-9/4a ?

The scatter plot of Credit balance ($) versus Size show that the slope of the „best fit‟ line is upward (positive);this indicates that Credit balance varies directly with Size. As Size increases, Credit Balance also increases vice versa. Correct

h. Copy the value of an existing double variable z into an existing int variable x.

From graph a, we can see that there is a weak negative liner relationship between AGE and English scores; the correlation is -0.042; the equation of regression is ENGLISH=-0.0814809*AGE+24.469; the slope is -0.0814809 which is negative; when the predictor

STEP 3: This time, however, since we are treating it as 3 x 10 = 30. We multiply 38 x 3.

Problems 1 through 5: Find the roots (values of x when the expression is equal to zero) using factoring. Prove your answers are correct by checking, or showing that the values of x you computed satisfy the original equation.

was 40, and C was 41, but I needed to get 80 but when you add B+C when A is forty then it's wrong. So
