Compare the calculations displayed in GeoGebra with the calculations you completed in parts A through D. Look in the Algebra
margin too. Do the results in GeoGebra match the results you obtained earlier? If not, where do the discrepancies occur? You
might have to rearrange equations algebraically to determine whether two equations match. Part 6
You've seen two methods for finding the area of AABC-using coordinate algebra (by hand) and using geometry software.
How are the two methods similar? How are they different? Why might coordinate algebra be important in making and using
geometry software?

Hope This Helps!!!

Hello.

First, let's use the Distributive Property and distribute -4:

[tex]\mathrm{-4(x+2)=24}[/tex]

[tex]\mathrm{-4x-8=24}[/tex]

Now, add 8 to both sides:

[tex]\mathrm{-4x-8+8=24+8}[/tex]

[tex]\mathrm{-4x=24+8}[/tex]

[tex]\mathrm{-4x=32}[/tex]

Now, divide both sides by -4:

[tex]\Large\boxed{\sf{x=-8}}[/tex]

I hope it helps.

Have a nice day.

Answer:

p = 170

Setting up the formula:

The mean is the sum of the digits divided by the total digits in the set.

[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = \text{Mean}[/tex]

[tex]\rightarrow \dfrac{\text{Sum of digits}}{\text{Total digits}} = 39[/tex]                                                                     [Mean = 39]

[tex]\rightarrow \dfrac{25 + p}{\text{Total digits}} = 39[/tex]                                                     [Sum of digits = 25 + p]

[tex]\rightarrow \dfrac{25 + p}{5} = 39[/tex]                                                                         [Total digits = 5]

Step-by step calculations:

Use cross multiplication:

[tex]\rightarrow 25 + p= 39 \times 5[/tex]    

Simplify the RHS:

[tex]\rightarrow 25 + p= 39 \times 5[/tex] 

[tex]\rightarrow 25 + p= 195[/tex] 

Subtract 25 both sides:

[tex]\rightarrow p = 195 - 25[/tex]

[tex]\rightarrow p = 170[/tex]

Answer:

x=3/2

y=4

Step-by-step explanation:

3y=6x+3

3y=4x+6

we see that 3y=3y so even the right side of the equations are equal.

6x+3=4x+6

6x-4x=6-3

2x=3

x=3/2

so easily we find y

we found that x=3/2 so

3y=6*(3/2)+3=9+3=12

y=12/3=4

so the solution of simultaneous equation is

x=3/2

y=4

Step-by-step explanation:

I think original price is $350

the discount will be 25% of 350 so it will be 25/100 x 350 to get 87.5 dollars

the new price's percentage is 100% -25% so to get the new price it'll be 75% of 350 to get 262.5 dollars

Answer:

  B.  Option 2 (only)

Step-by-step explanation:

A geometric sequence is a sequence of terms that have a common ratio.

The deposits are ...

  100, 50, 50, 50, ...

The ratios of terms of this sequence are ...

  1/2, 1, 1, 1

So, the ratio is not constant, and the sequence is not geometric.

__

The deposits are ...

  5, 10, 20, 40, ...

The ratios of terms of this sequence are ...

  10/5 = 2, 20/10 = 2, 40/20 = 2, ...

The ratio is constant, so the sequence of deposits for Option 2 is geometric.

The equation, which is used to find any corresponding length and width that fit the pattern in the provided table is,

[tex]I=\dfrac{k}{w}[/tex]

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

[tex]A=a\times b[/tex]

Here, (a)is the length of rectangle and (b) is the width of the rectangle.

A rectangle with constant area has possible lengths and widths as shown in the table below.

Width vs. Length of a rectangle

In the above table, the length of a rectangle is decreasing with increasing the width of a rectangle.

For such relation, the value of w should be inversely proportional to the length of it. The first option given as,

[tex]I=\dfrac{k}{w}[/tex]

Here l is the length, w is the width, and k is a constant (w not-equals 0).

In this expression, the length of the rectangle is inversely proportional to the width of the rectangle.

Thus, the equation, which is used to find any corresponding length and width that fit the pattern in the provided table is,

[tex]I=\dfrac{k}{w}[/tex]

Answer:

24 minutes

Step-by-step explanation:

Given:

Distance per lap = 2 miles

Speed of Lou Lambert = 160 miles/hr

Speed of Ralph Redding = 170 miles/hr

Speed difference between the two = 170 - 160 = 10 miles/hr

Therefore, we can say that Ralph gains 10 miles in 60 minutes over Lou.

We have to find the time in which Ralph will gain 2 laps i.e. 2 [tex]\times[/tex] 2 = 4 miles.

Let us use unitary method to find the required time.

10 miles are gained by Ralph in 60 minutes

1 mile will be gained in [tex]\frac{60}{10} = 6\ minutes[/tex]

4 miles will be gained in 6 [tex]\times[/tex] 4 = 24 minutes
