7n-1>-169
+1 both sides
7n>-168
÷7 both sides
n>-24
Answer:
In this equation X is independent variable while Y is dependent variable.
Step-by-step explanation:
Equation:
Y=10x+100
Independent variable in math:
A variable in an equation that may have its value freely chosen without considering values of any other variable.
Dependent variable in math:
A dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value of other variable.
<u>According to above definitions Y is dependent of x. As we changes the value of x the value of Y changes.</u>
For example if x = 1, Y will be 110.
And if x = 10, Y will be 200.
Answer:
Distance = rate x time or d = rt...that means time t = d/r...and we have
t = 21 km / .5 km/hr = 42 hr
