Answer:
a=4, b=5/2
Step-by-step explanation:
Assuming the given equation is
We expand the left hand side to get:
If this equation must have infinitely many solutions, then
Also we must have
Put a=4 to get:
Answer:
yes
Step-by-step explanation:
think about just past the decimal is 431 greater than 419
It is important to note that when we say proportional, the increase in the value of the independent variable (in this case, distance x) will also increase the value of the dependent variable (density, d). Using k as the proportionality constant, the answer to this question would then be,
d = kx
I think
