Choice A is the answer which is the point (1,-1)
=========================================
How I got this answer:
Plug each point into the inequality. If you get a true statement after simplifying, then that point is in the solution set and therefore a solution. Otherwise, it's not a solution.
-------------
checking choice A
plug in (x,y) = (1,-1)



This is true because -3 is equal to itself. So this is the answer.
-------------
checking choice B
plug in (x,y) = (2,4)



This is false because 0 is not to the left of -3, nor is 0 equal to -3. We can cross this off the list.
-------------
checking choice C
plug in (x,y) = (-2,3)



This is false because 7 is not to the left of -3, nor is 7 equal to -3. We can cross this off the list.
-------------
checking choice D
plug in (x,y) = (3,4)



This is false because -2 is not to the left of -3, nor is -2 equal to -3. We can cross this off the list.
AB/DE = BC/EF
CA/FD = AB/DE
MJ/QN = JK/QP
LM/PQ = MJ/OP
Answer:
18
Step-by-step explanation:
Since he does 90 cars-----5 days
x cars--------1 day
we multiply 90 by 1 then over 5
Answer:
y = 2x - 3
Step-by-step explanation:
The slope intercept form of a linear equation is y = mx + b
We know that m = 2
We can plug in x and y values to find b
17 = 2(10) +b
b = 17 - 20
b = -3
Therefore,
y = 2x - 3
To solve the two sets of equations simultaneously, subtract one equation from the other to obtain
3x^5 + 2x^2 - 10x + 4 - (4x^4 + 6x^3 - 11) = 0
3x^5 - 4x^4 - 6x^3 + 2x^2 - 10x - 7 = 0
This is a polynomial of degree 5 to be solved for zeros.
A graphing calculator will yield 3 real zeros (verifiable by Descartes Rule of Signs).
