Answer:
It is similar in that you have to move everything to one side and get rid of coefficients on the variable.
It is different in that you aren't solving for the actual numerical value of the variable and are just solving in terms of other variables.
Step-by-step explanation:
One step equations and literal equations both are similar because you have to move everything to the other side to isolate the variable, and also divide or multiply to get rid of any coefficients on the variable to solve it.
However, they are different because one-step equations actually need you to solve for the numerical value of the variable. On the other hand, literal equations aren't solved completely and are not numerical answers, it is just the variable solved in terms of other variables.
Answer:
radius=3.19 km
Step-by-step explanation:
32/3.14159=r^2
r=3.19 km
In order to answer, you need to sketch the given exponential curves and straight lines and ask yourself if and when do they cross each other:
a) 2ˣ + 1 is an esponential curve with base >1 shifted up by 1;
-3x + 6 is a straight line with negative slope, shifted up by 6;
They cross each others only one time.
b) 3ˣ - 3 is <span>an esponential curve with base >1 shifted down by three, thus it can be negative;
2x - 2 is </span><span> a straight line with positive slope shifted down by 2;
They cross each others twice.
c) -4</span>ˣ - 1 is <span>an esponential curve with base >1 flipped over the x axis and shifted down by 1;
3</span>⁻ˣ - 2 is an esponential curve with base <1 ( 3⁻ˣ = (1/3)ˣ )and shifted down by 2;
They never cross each others.
Therefore the correct rder is:
-4ˣ - 1 = 3⁻<span>ˣ - 2
</span>-3x + 6 = 2<span>ˣ + 1
</span>3<span>ˣ - 3 = 2x - 2</span>
we have given y interms of x.
we have given that add 2 to x.
which means
so we have .
so when x.
