Algebra 2 willing to give points to all of my questions

Hello from MrBillDoesMath!

Because logarithms convert exponents to multiplication.

log (a^b) = b * log(a)

Discussion:

For example, it's not easy to solve for x in 10^x = 3 withtout logarithms. With logarithms,  take (base 10) log's of both sides:

x * log10 = log3                 => as log10 = 1

=> x = log3

so x, former;y an exponent, becomes easy to solve for.

Thank you,

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

ask goog great chance of finding the solution there
