Answer:

y -4 = 3(x +1)

Step-by-step explanation:

The point-slope form of the equation of a line with slope m passing through point (h, k) is ...

y -k = m(x -h)

Your values for these parameters are ...

m = 3

(h, k) = (-1, 4)

Filling these into the form gives the equation you're looking for:

y -4 = 3(x +1)

Which of the following must describe a irrational number? A. a number with a repeating or terminating decimal expansion B. a num

Olenka [21]

Answer:

Step-by-step explanation:

A irrational number can be defined as those numbers which are real but can NOT be expressed in simple fractions. The term 'irrational' means 'a number which can not be expressed in ratio of two integers', 'no ratio.'

<u>When a irrational number is expressed in decimal, the numbers keep on expanding without repeating andd without terminating, which means it keeps on expanding infinitely.</u>

For example, π (pi) is an irrational number. When it is expressed in decimals it keeps on expanding non-repeatedly and unendingly.

Another example of an irrational number is √2.

Thus the correct statement that defines irrational number is option D.

If ab = c - d, which of the following is an expression for d in terms of a, b, and c?

horsena [70]

ANSWER

$d = - ab + c$

EXPLANATION

The given expression is

$ab = c - d$

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.

This means that, we need to isolate d on one side of the equation while all other terms are on the other side.

We subtract from both sides of the equation to obtain,

$ab - c = - d$

We now divide through by -1, to get,

$- ab + c = d$

Or

$d = - ab + c$
