What is the approximate value of 2 -3
Lemur [1.5K]

Assuming you are doing x minus y, the value would be -1.00

The number line can help - go left three times from 2 and you get an answer.

Assuming you are doing x times (-y), the value would be -6.00

Add -3 to itself 2 times

4. Ariel loves to go to baseball games. This season she has already attended 23 New York Ducks games. If
san4es73 [151]

Answer: She attended to 7 weekday games.

Step-by-step explanation:

Let's denote our variables as:

Wd = number of weekday games that she attended.

We = number of weekend games that she attended.

We know that in total, she attended to 23 games, so we have:

Wd + We = 23.

"If  Ariel attended nine more weekend games than weekday games" can be written as:

We = Wd + 9.

Then we have the system of equations:

Wd + We = 23.

We = Wd + 9.

The first step would be to replace the second equation into the first one, as:

Wd + We = 23.

Wd + (Wd + 9) = 23

Now we can solve this for Wd.

2*Wd + 9 = 23

2*Wd = 23 - 9 = 14

Wd = 14/2 = 7

She attended to 7 weekday games.

And:

We + 7 = 23

We = 23 - 7 = 16

She attended at 16 weekend games.

aleksley [76]

Answer:

x=0

Step-by-step explanation:

Evaluate all the arithmetic first, and then remember absolute value equations have two possible ways to go (+ and -).

You can see how I split them on the 3rd line, later demonstrating how the 2nd one is invalid.

|3-x|-x+1=4\\\\|3-x|-x=3\\\\3-x-x=3\\-(3-x)-x=3\\\\3-2x=3\\-3+x-x=3\\\\-2x=0\\-3\neq 3\\\\x=0\\-3\neq 3\\

Therefore, the solution is x=0

What is the area of this triangle in the coordinate plane?
Klio2033 [76]
Hey. Let me help you on this one.

In order for us to solve this problem, we will be needing to find both length and width of the triangle on this coordinate plane. We will also need to know how to use the triangle area formula. 

I will be attaching an image containing the shown difference between a rectangle, and a triangle, and on how to understand why the area of a triangle is like this.

First of all, let's find the length of the triangle. It's 11 units, and we can determine that by counting up all of the units, or simply finding the difference between x-point 13 and 2, which is going to be 11.

Same applies to the width of the triangle. We will need to either count up all the units individually, or find a difference between a higher y-point and lower y-point. That difference is going to 5 units, since 9-4=5.

Now, let's use the formula for the triangle area and substitute the values.

S= \frac{a*b}{2}
S= \frac{11*5}{2}
S= \frac{55}{2}
S=27.5

Answer: Area of the triangle on the coordinate plane is 27.5 units squared.

In 2014, The population of West Palm Beach, Florida was 99,919. Write The 2014 population of West Palm Beach in scientific notat
frez [133]

Answer:

9.9919*10^4

Step-by-step explanation:

we have

99,919

we know that

99,919=9.9919(10,000)

10,000=10^4

substitute

9.9919(10^4)

therefore

The 2014 population of West Palm Beach in scientific notation is equal to

9.9919*10^4
