To equations are equivalent if and only if they have the same solution set.
Solve for both of the equations.
-2x = 10
x = -5 <-- Divide both sides by -2
-5x = 25
x = -5 <-- Divide both sides by -5
Both have the solution -5.
So, yes both are equivalent.

ANSWER

EXPLANATION
The exponential function that models cell duplication in the lab is given as

We want to determine the time it will take for the cells to increase to

In other words, we want to find the value of

when

This gives us the equation,

Recall that,

We apply this property to the right hand side to obtain,

This implies that,

We divide both sides by 4 to get,

We take the antilogarithm of both sides to base 10 to get,

This implies that,

to the nearest hundredth.
No, because there is a remainder of 15 when P(x) is divided by x−8.
Answer:
It is a function.
Step-by-step explanation:
By definition, a function relates each element in the domain to only one element in the range. This means that each vertical line you draw through the x-axis can intersect the function at only one point. ... y = 2x +1. This is the equation of a straight line with slope 2 and y-intercept 1, so it is a function.
A linear function is two distinct but related notions. So, y=2x-1 is also a linear function.
