Answer:
4
Step-by-step explanation:
The product of a number m and 4 is 16
=m×4=16
16÷4=4
Answer:
It is proportional, as y increases in line with x, and they have a linear relationship.
Solution:
The question given is a negative exponent.
To solve this, we apply the law of indices for negative exponents.
Negative exponent law is indicated below;
Thus, applying this law to the question;
Given:
a = 6
Substituting a = 6 into the expression, we have;
Therefore, the correct answer is;
Answer:
When travelling downstream, the speed of the boat and the current add up.
Let the speed of the boat is b and the speed of the current is c.
<u>Use distance formula: </u>
- d = st, d-distance, s- speed, t- time
a)
<u>Then we have equation:</u>
b)
<u>If c = 2, then the equation is</u>:
- 12(b + 2) = 336
- b + 2 = 28
- b = 26 km/h
If the value of a is positive, the line slopes upwards.
