Answer:
Second option: (-2,-3) and (1,0)
Step-by-step explanation:
Given the system of equations
, you can rewrite them in this form:

Simplify:
Factor the quadratic equation. Choose two number whose sum be 1 and whose product be -2. These are: 2 and -1, then:

Substitute each value of "x" into any of the original equation to find the values of "y":

Then, the solutions are:
(-2,-3) and (1,0)
Answer:
x^3 +x^2 +x+1
Step-by-step explanation:
Your welcome!!!!!!!!!!!
That's a copy of the figure from the other post; I didn't look at the answer.
We have Start(0,0)




Your team takes the direct path at a constant speed of 6 miles per hour.
<span>Our team.

</span><span>
Team Red follows the riddle and travels at 8 mph from Start to Post A, 9 mph from Post A to Post B, and 11 mph from Post B to Finish.
Team Blue follows the riddle and travels at a constant speed of 10 mph.
</span>

<span>
Team Yellow follows the riddle and travels at a constant speed of 11 mph, but stops at Post A for 30 minutes and stops again at Post B for another 30 minutes.</span>

Winner: our team, then Blue, then Red, then Yellow

Your answer is ab -c
multiply both sides by B
Then subtract C
Follow PEMDAS
22 x 12 = 264
11 + 5 = 16
264 + 16 = 280
280 - 10 = 270
270 is your answer
hope this helps
