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:
B) 25
Step-by-step explanation:
First, you add up all the numbers. Then, you divide it by 9 which is the total amount of numbers there are.
Answer:
radius = √5 = 2.24 to nearest hundredth.
Step-by-step explanation:
(x + 3)^2 + (y + 3)^2 = 5 comparing with the standard form
(x - h)^2 + (y - k)^2 = r^2
-h = 2 so h = -3, -k = 3 so k = -3.
r^2 = 5 so r = √5.
Answer:
B. 3.27 x 10^11.
Step-by-step explanation:
There are 11 digits after the first one, so it is
3.27 x 10^11.
