Answer:
x=2
z=80
Step-by-step explanation:
Since (7x+66) and (11x+78) are a linear pair, their measures are supplementary and therefore add up to 180 degrees. z and (7x+66) are also vertical angles, meaning that they are equal.
7x+66+11x+78=180
18x+144=180
18x=36
x=2
z=7x+66=7(2)+66=14+66=80
Hope this helps!
Answer:
-54
Step-by-step explanation:
plug (-4) in for t and solve for k(t)
72 minutes
convert 8 hours to minutes ⇒ =8 × 60 = 480 minutes
15% of 480 = 0.15 × 480 = 72 minutes

Answer:
Only Graph D
Step-by-step explanation:
A trend line indicates the general course (or average course) of the points on the graph. In Graph C, the general trend seems to intercept at a positive y-value. In Graph D, the trend will continue past the X-axis and intercept at the negative Y-axis.
