Answer:
y = 108°
Step-by-step explanation:
Since AB and CD are parallel lines, then
3x - 12 and 2x + 16 are corresponding angles and congruent, thus
3x - 12 = 2x + 16 ( subtract 2x from both sides )
x - 12 = 16 ( add 12 to both sides )
x = 28
Thus
3x - 12 = 3(28) - 12 = 84 - 12 = 72°
y and 3x - 12 are adjacent angles and supplementary, thus
y = 180° - 72° = 108°
Sine = opposite / adjacent.
since the opposite and adjacent lines are used, you need to use some to solve for x.
the answer is sine.
Total cost independent variable
Pounds of candy dependent variable
Step-by-step explanation:
A variable is a condition that is liable to change. Most experimental hypothesis use variables to draw up suitable statements to test.
- An independent variable is that variable that does not rely on another variable. It induces the change or variation in another variable. In the statement above, the total cost is the independent variable.
- The other variable which is the effect resulting from the variation of the independent variable is the dependent variable. Here it is the number of pounds of the candy that changes when total cost varies.

Distance formula between 2 points (x1,y1) and (x2,y2)
D=

D=29 and one point is (-5,5) and the other is (k,0)
sub
29=

29=

square both sides
841=

841=

minus 25 both sides
816=

square root both sides don't forget positive and negative roots
+/-4√51=-5-k
add 5 to both sides
5+/-4√51=-k
times -1 both sides
-5+/-4√51=k
the possible values for k are
k=-5+4√51 or k=-5-4√51
