Answer:

k(x) = |x - 4| - 2

Step-by-step explanation:

So we know that k(x) is shifted 4 untis to the right and 2 units down. In an absolute value function, the value you move to the left will be positive and the value you move to the right will be negative. Since we are moving to the right, our value will be negative.

When you shift the function up or down, you will either subtract or add that value out side the absolute value. Since we are shifting down 2 units, that means we will be subtracting by 2.

15-(4m - 5) = 32 please help me

Answers

Answer:

m = -3

Step-by-step explanation:

15 - (4m - 5) = 32            (Given)

15 - 4m + 5 = 32             (Distributed)

20 - 4m = 32                  (Added like terms)

20 - 4m - 20 = 32 - 20  (Subtract 20 on both sides)

-4m = 12                         (Simplify)

-4m/-4 = 12/-4                (Divide -4 on both sides)

Create an example of a rational value between -8 and -9 and show the work

Answers

Answer:

-8.75

Step-by-step explanation:

Rational: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.

A rational number is a number that can be expressed as a fraction with an integer numerator and a positive integer denominator. Two different fractions may correspond to the same rational number. 1/2 = 2/4. Every whole number is a rational number. These can be written as N/1 = N, so they are rational numbers.

Every number could be entered as a fraction using an integer is considered a rational number.A quotient p/q for two integral numbers could be expressed as q not equal to 0.The number can be stated as an integer quotient divided by non-zero.Rational numbers could finish or repeat decimals within the decimal form.

Using formula:

[tex]\to \bold{rational\ value =\frac{a+b}{2}}[/tex]

Given:

a=-8

b=-9

Calculating the rational number:

[tex]\to \bold{rational\ number=\frac{-8+(-9)}{2}}[/tex]
