das is 20 points per user, just fyi



1. distributive property

recall that a(b+c)=ab+ac

5(3x-4)=5(3x)+5(-4)=15x-20



2. bruh, I can't show that here, wait, nvm, see attachment




3.

100% is double the price

45*2=90

the item will sell for $90 in store



4.

1/2+1/4+1/8=

4/8+2/8+1/8=

7/8

How do I find these equations using substitution y=-3x+5 and 5x-4y=-3 ?
lapo4ka [179]

Answer:

x=1

Step-by-step explanation:

you would change it to 5x-4(-3x+5)=-3, because you put the info for the first equation into the second equation.

5x-4(-3x+5)=-3

5x+12x-20=-3

17x-20=-3

17x=17

x=1

Select the point that is a solution to the system if inequalities yx^2-6
labwork [276]

Answer:

The correct answer is A.

A(0,-2)

Step-by-step explanation:

Method 1

You just have to plot each point on the graph.

The one that falls within the solution region is the correct choice.

From the graph, A(0,-2) falls within the solution region.

See graph

Method 2

If you substitute the points into the inequalities, the only point that will satisfy both inequalities simultaneously is A.

The first inequality is

y\:

If we substitute A(0,-2), we get;

-2\:


-2\:


This statement is true.

The second inequality is

y\:>\:x^2-6

If we substitute A(0,-2), we get;

-2\:>\:(0)^2-6

This gives,

-2\:>\:-6

This statement is also true.

Use the regression calculator to compare the teams’ number of runs with their number of wins. a 2-column table with 9 rows. colu
-Dominant- [34]

The equation of the trend line is ŷ = 0.15x - 23.21

<h3>How to determine the average rate of change of the trend line?</h3>

The points are given as:

hr =>808, 768, 655, 684, 637, 619, 613, 609, 563

w =>  93, 94, 66, 81, 86, 75, 61, 69, 55.

Using a graphing calculator, we have the following calculation summary:

  • Sum of X = 5956
  • Sum of Y = 680
  • Mean X = 661.7778
  • Mean Y = 75.5556
  • Sum of squares (SSX) = 50569.5556
  • Sum of products (SP) = 7547.1111

The regression equation is represented as:

ŷ = bX + a

Where:

b = SP/SSX

b = 7547.11/50569.56

b = 0.14924

a = MY - bMX

a = 75.56 - (0.15*661.78)

a  = -23.20961

This gives

ŷ = 0.14924X - 23.20961

Approximate

ŷ = 0.15x - 23.21

Hence, the equation of the trend line is ŷ = 0.15x - 23.21
