Answer:
-5/2
Step-by-step explanation:
With Distributive property, we get 4x + 4 = -6. Subtract 4 from both sides and we get 4x = -10. Divide both sides by 4 and we get x = -5/2.
Answer:
490kpa
Step-by-step explanation:
V1 = 70ml and P1 = ? kpa
V2 = 15ml and P2 = 105kpa
if 15ml will give me 105kpa
then how many times is 70ml greater than 15ml
70/15 = 4.6667
then multiply it by 105kpa
4.6667 * 105 = 490kpa
meaning that if 15ml will give me 105kpa
then 70ml which is (15*4.667) will give 490kpa
Answer:
Number of courses would best be considered a discrete variable and drive time would be considered a continuous variable.
Step-by-step explanation:
Discrete variable:
Countable amounts(0, 1, 2, 3,...)
Continuous variables:
Can be decimal values.
In this question:
The number of courses is a countable amount(0,1,2,3,...), you cant take half a course, for example, so it is discrete. Otherwise, drive time accepts half minutes, for example, 10.5 minutes, so is continuous.
Number of courses would best be considered a discrete variable and drive time would be considered a continuous variable.
B. because anything raised to a power besides 1 isnt linear.
