2 ways
zero product property
easy way
zero product
factor perfect square
m^2-3^2=0
(m-3)(m+3)=0
set each to zero
m-3=0
x=3
m+3=0
m=-3
m=-3 or 3
easy way
add 9 to both sides
m^2=9
sqrt both sides remember to take postive and negative roots
m=+/-3
m=-3 or 3
B is answer
It’s wether dividing or multiplying
The largest change in temperature was between July and March/April
1. is D) 4/3 To find the slope we will insert the numbers into this formula: y2 - y2 / x2 - x1, so... 1 + 3/ 1 + 2 (the negatives canceled each other out)
now simplify and it becomes 4/3
so ur answer to 1. is D) 4/3
2. Plot this one...it rly helps...then use the slope to find the point ur looking 4, the answer is C) -2
3. The answer is B) -2
Hope that helps u out!! :)
