Answer:
a = 17
Step-by-step explanation:
Because all the lines are congruent (same length) as indicted by the lines, this means that every angle is the same.
180 ÷ 3 = 60
So every angle is 60°
This also means that:
4a - 8 = 60
Isolate the 4a by moving the -8 over to the other side, making it a +8:
4a = 60 + 8
4a = 68
Now simply divide both sides by 4 to get the value of 1a:
a = 17
<h3>So a = 17 </h3><h3 /><h2>Hope this helps!</h2>
Answer:
The graph represent a scatter plot between variable A on the horizpntal line and the variable B on the vertical line.
A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line.
As shown by graphinf a line through the maximum number of points, balancing about an equal number of points above and below the line, we can deduce that:
<u>The line of best fit drops from left to right, so the variables have a negative correlation. </u>
Parentheses first
9q-14+3q-3(8)=7
9q-14+3q-24=7
Combine like terms
9q + 3q - 14 - 24 = 7
12q -38=7
add 38 to both sides
12q - 38 + 38 = 7 + 38
12q = 45
divide both sides by 12
q = 45/12
q = 3.75
Option ( C ) is the correct answer.
