we can take a peek at two of those lines hmmm say y = 5x + 3 and y = 5x + 7.
let's notice, those two equations for those lines are in slope-intercept form, so let's solve the system.
since y = y then
5x + 3 = 5x + 7
3 = 7 what the?
well, notice, both lines have the same slope of 5, but different y-intercept, one has it at y = 3 and the other at y = 7, what does that mean?
it means that both lines are parallel to each other, one may well be above the other, but both are parallel, and since a solution to the system is where their graphs intersect, well, parallel lines never touch, so a system with two parallel lines has no solutions.
1 cm is regular
but 1 cm 2
means that you multiply 1 by 1 which is 1
for example if you have 15cm 2 you would multiply 15 by 15 and get 225
and 15 cm 3 would be 15*15*15 and you would get 3375
Answer:
The solution is (x,y)=(-4,-1)
Step-by-step explanation: Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
The answer is B. Genetic Drift is events that change in a frequency of a gene variant (allele) in a population due to random sampling of organisms.
