How do i write a Word phrase to represent the numerical expresion 5+(17-8)
Lerok [7]

Answer:

If i was to read this out loud, i would say: 5 plus the quantity of 17 minus 8.

Step-by-step explanation:

5 + (17-8)

Parenthesis need to be done first! That is why you need to say 'the quantity of...' You also have to add 5 to it all, and you might as well do it before 'the quantity of...' becuz it comes before it in the numerical expression.

YAY! ! ! YOU GOT IT!!! =)

Help find domain and range
kolezko [41]

Answer:

d: 4 r:5

Step-by-step explanation:

for domain the x coordinates doesn't go over -2 on the left or 2 on the right so if u add the units of the space in between it's 4 since 2- (-2)=4

for the range, the y coordinates never goes over 3 or -2 so range is 5 is u add the units in between

I hope that makes sense!

Help please!!!!!!! and thank you
GarryVolchara [31]

Answer:

2.50000 or 2.5 or 2 1/2

Step-by-step explanation:

You have the number 250,000. you have to get the decimal between 1.00 and 10.00 to do this we are going to move the decimal over left one at a time.

25,000.0

2,500.00

250.000

25.0000                     25 is really close but not between 1 and 10 so were going to move the decimal one more time

2.50000

2.50000 is between 1 and 10 so its the anwser we are looking for.

PLZ help<br> What system of linear inequalities is shown in the graph?
GarryVolchara [31]

In order find the Inequalities, First we need to Find the Equations of Both the Lines.

<u>Equation of First line :</u>

It is passing through the Points (0 , 2) and (4 , 0)

⇒ Slope = \frac{2 - 0}{0 - 4} = \frac{-2}{4} = \frac{-1}{2}

⇒ Equation of the First Line : y - 2 = \frac{-1}{2}(x)

⇒ Equation of the First Line : x + 2y = 4

<u>Equation of Second Line :</u>

It is passing through the Points (1.5 , 0) and (0 , -3)

⇒ Slope = \frac{0 + 3}{1.5 - 0} = \frac{3}{1.5} = 2

⇒ Equation of the Second Line : y + 3 = 2x

⇒ Equation of the Second Line : 2x - y = 3

As the Shaded Area of the First Line is away from the Origin :

⇒ x + 2y ≥ 4

As the Shaded Area of the Second Line is towards the Origin and it is a Dotted line :

⇒ 2x - y < 3

So, the System of Linear Inequalities are :

⇒ x + 2y ≥ 4

⇒ 2x - y < 3
