New price is 1.05 because if you multiply 1.50 by .30 then your answer is 45. subtract 45 from 1.50 you get 1.05
Answer:
10000
Step-by-step explanation:
Answer:
<em>The rate of the equation is r when r is a constant</em>
Step-by-step explanation:
We need to solve for the rate of the equation
d = rt
Differentiating on both sides with respect to time
= 
Considering r as a constant
= r×
where, = 1
= r
<em> The rate of the equation is r when r is a constant</em>

I don't know about how to put that in standard form, but an equation has to have an equals sign... So, that would be an equation.
Answer:
x = -2 or x = 1/2
Step-by-step explanation:
First get the eq in standard form, which means:
x² should not have that 2 in front of it
move the other 2 to the left
so first let's divide by 2:
x² + 3/2 x = 1
now move the 1 to the left
x² + 3/2 x - 1 = 0
now look for two numbers that, when multiplied, give -1, and when added, give 3/2. This is a bit of trial-and-error if you want to solve in this way.
The numbers are 2 and -1/2, since 2*-1/2 = -1, and 2 - 1/2 = 3/2
The factorization thus is:
x² + 3/2 x - 1 = (x+2)(x-1/2) = 0
Either factor (x+2) or (x-1/2) can be zero to solve the solution, hence x = -2 or x = 1/2
