Answer:

A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound and subtract it from the rounded value for the lower bound.

Determine the values of k for which the equation has no solution:

Bingel [31]

Let's rewrite the equation as

$|3x+k| = 1-4 = -3$

This should be enough to convince you that the equation has no solutions, no matter which value for k you choose. In fact, the left hand side of the equation is an absolute value, which by definition is always positive, or zero in the worst case.

The equality asks for this quantity to equal -3, a negative number.

A non-negative quantity can never equal a stricktly negative quantity, so the equation has no solutions.

11 subtracted from the quotient of a number and 5 is -13

Katyanochek1 [597]

Answer:

n/5 - 11 = -13

Step-by-step explanation:

We must do the division first, before the subtraction:

"the quotient of a number and 5" is n/5."

"11 subtracted from this result" comes out to n/5 - 11 = -13.

This is the answer. We were not asked to simplify it. But if we want to simplify it, we add 11 to both sides, obtaining n/5 - 2.
