Answer:
- 4
Step-by-step explanation:
Using the rule of exponents
• 
× 
⇔ 
• 
⇔ 
= 
= 
and right side
= 
× 
Hence
= 
× 
= 
Equating exponents on both sides gives
a + 10 = - 2a - 2 ( add 2a to both sides )
3a + 10 = - 2 (subtract 10 from both sides )
3a = - 12 ( divide both sides by 3 )
a = - 4
Average rate of change = change in y ÷ change in x
We already know the change in x because we are measuring the x values from -3 to 0.
change in x = 0-(-3) = 3
To find the change in y find the difference between the corresponding y-values when x=0 and when x=-3.
change in y = 0.5-2 = -1.5
average rate of change = -1.5/3 = -0.5
answer: -0.5
Answer:
x=30
Step-by-step explanation:
53+97+x=180
150+x=180
x=30
Answer:
d
Step-by-step explanation:
Answer:
162°
Step-by-step explanation:
To convert from radian to degree measure
degree measure = radian measure × 
, then
degree = 
× ( cancel π and 10/ 180 to simplify )
= 9 × 18
= 162°
