Answer:
Add -4x to both sides--> 6x+9=4x-3 and 2x+9=-3
multiply both sides by -1/4 --> -4(5x+7)=-18 and 5x-7=4.5
multiply both sides by 1/4--> 12x+4=20x+24 and 3x+1=5x+6
multiply both sides by -4--> -5x/4=4 and 5x=-16
add -4 to both sides--> 8-10x=7+5x and 4-10x=3+5x
According to the question, we are to complete a 2-column proof to show that the measure of BC is equal to EF:
Given the following:
AC = AB + BC....................... 1
AC = AB + x ............... 2
From equation 2, AB = AC - x ................. 3
Substitute equation 3 into 1:
AC = AB + BC
AC = AC-x + BC
AC-AC = -c + BC
0 = -x + BC
BC = x
Since AC is greater than AB by a value of x, hence AC > BC

Answer:
Negative linear association/correlation.
Step-by-step explanation:
The type of association that is shown in the scatter plot is negative linear association since it declining at a steady rate with a few outliers. It resembles a line going downwards or sloping downwards.
Add up all of your X’s!! then Try and add up all of the degrees I think. Check me if i’m wrong !
