"a "and "b^2-4ac" must be negetive
The answer is the option A, which is: A. x-7=x²+2x-4
The explanation is shown below:
To solve this problem you must apply the proccedure shown below:
1. You have the following system equations given in the problem above:
<span>y=x-7
y=x²+2x-4
2. Therefore, when you substitute for y in the bottom equation, you obtain:
</span>x-7=x²+2x-4
Answer:
D. $5,000
Step-by-step explanation:
The amount of money he should deposit is the principal.
The principal P can be gotten by
P = 100 I /RT
Where
I = interest
R = rate
T = Time
Given
I = $240
R = 1.6%
T = 3 yrs
P = 100 x 240 /1.6 x 3
Multiply through
= 24000/4.8
= $5000
Answer:
0.09
Step-by-step explanation:
