You can plug -x - 1 for y in the first equation
2x - (-x - 1) = 10
2x + x + 1 = 10
Combine
3x = 9
Divide
x = 3
Plug 3 for x in any equation ( I'll use th second equation )
y = - (3) - 1
y = - 3 - 1 = -4
x = 3 ; y = -4
(3, -4)
1. 1000 2. 0.001. hope this helps.
<span>The correct option is "20" because
f(n)=<span>n2</span>−n
(−4)=(−4<span>)2</span>−(−4)
=16+4
=20</span>
In the given expression 6X² + 13X +6, we can easily identify the values of a, b and c. These values are a=6, b=13 and c=6
For the value of "ac", we have:
ac=6*6
ac=36
For a sum of b are 4, we have
ac+b=36+13=49
Therefore, the answer for the last question "The two numbers that have a product of ac and a sum of b are 4 and 9".
Answer:
Option C is correct.
The y-intercept of the graphed function is; 
Explanation:
To find the y-intercept of the graphed function:
The point where the graph crosses the y-axis is call y-intercept.
You can also find the y-intercept by looking at the given graph and seeing which point crosses the y-axis also this point will always have an x-coordinate of 0.
End behavior of a polynomial function is the behavior of the graph of function as x approaches
or
Also, the degree and the leading coefficient of a polynomial function determine the end behavior of the graphed function.
therefore, the y-intercept of the graphed function is; (0, -9)
