Answer:

Step-by-step explanation:
Open the brackets.



To convert hour into minute: (No. of hour × 60) minutes
So, 2/5 hours = (2/5 × 60) minutes = (120/5) minutes = 24 minutes
Answer:
0.8
Step-by-step explanation:
-2.8 + 3.6 = 0.8
Answer:
As x decreases without bound, f(x) increases without bound
As x increases without bound, f(x) approaches 0
Step-by-step explanation:
As x gets more and more negative f(x) gets bigger and bigger
f(x) = (7/10) ^ x but x is negative so flip it and then x is a larger number
(10/7) ^ large number so it will get larger
as → -∞ f(x) →∞
As x gets more and more positive f(x) gets smaller and smaller
f(x) = (7/10) ^ x closer and closer to 0. The denominator gets larger faster than the numerator = 1 / large number
as → ∞ f(x) →0
<em>So to solve for a variable, you have to isolate that variable onto one side.</em>
<h3>14.</h3>
Firstly, multiply both sides by j: 
Next, divide both sides by k and <u>your answer will be:
</u>
<h3>15.</h3>
Firstly, add g on both sides: 
Next, multiply both sides by 5 and <u>your answer will be:
</u>
<h3>16.</h3>
Firstly, subtract 5p on both sides: 
Next, divide both sides by 9 and <u>your answer will be
</u>
