What is the vertex of the absolute value function defined by f(x)=|x+2|+4?

1 answer:

5 0

There is no maximum value for the term inside the absolute value signs, but there is an absolute minimum, being zero when x=-2. And when x=-2, y=4, and that is your vertex:

(-2, 4)

The length of rectangle is 2 meters more than its width . The area of the rectangle is 80 square meter . what is the length and

stich3 [128]

Let the width of the rectangle be x
then the length is x+2
we are given the area as 80 square meter
and we know the area of a rectangle is given by
area=L*W
area=(x+2)*x
but our area=80
80=(x+2)*x
x^2+2x=80
x^2+2x-80=0
we use the quadratic formula to solve this which gives us
x=8
therefore our width is 8
and our length is 10

What is the least common denominator for the fractions and ?<br> 9<br> 18<br> 27<br> 36

Mademuasel [1]

$\\ \sf\longmapsto \dfrac{9}{18}$

Cancel by 3

$\\ \sf\longmapsto \dfrac{3}{6}$

Cancel by 2

$\\ \sf\longmapsto \dfrac{1}{2}$

$\\ \sf\longmapsto \dfrac{27}{36}$

Cancel 9

$\\ \sf\longmapsto \dfrac{3}{4}$

Hence the denominator will follow the rule 2n means a multiple of 2

Answer:

The associative property will be:

$(14\textbf{.}\frac{1}{7})\frac{2}{5}$

So, Option C is the correct option.

Step-by-step explanation:

We need to write the expression that uses the associative property to make it easier to evaluate: $14(\frac{1}{7}\textbf{.}\frac{2}{5} )$

The associative property of multiplication states that: $a(b\textbf{.}c)=(a\textbf{.}b)c$

So, For the given expression:

$14(\frac{1}{7}\textbf{.}\frac{2}{5} )$

The associative property will be:

$(14\textbf{.}\frac{1}{7})\frac{2}{5}$

So, Option C is the correct option.

$56 they are 25% off wants to know what is the discount price

iVinArrow [24]

Answer:

$42

Step-by-step explanation:

This is an example of a percentage decrease.

To work out the percentage decrease you would first need to convert the percentage of 25% into a decimal. You can do this by dividing the percentage of 25 by 100, this gives you 0.25. This is because percentages are out of 100.

The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.

To work out the discounted price you would multiply the amount of $56 by 0.75, this gives you $42.

1) Divide 25 by 100.

$25/100=0.25$

2) Minus 0.25 from 1.

$1-0.25=0.75$

3) Multiply $56 by 0.75.

$56*0.75=42$
