The best answer is A. The possible roots of this polynomial function 9i and -9i. It is possible that this polynomial function is a quadratic equation. It has a degree of two which means there are two roots and it is possible that the positive and negative value of 9i are its roots.
No, the given point does not satisfy the inequality
<em><u>Solution:</u></em>
Given inequality is 6x + y > -11
We have to find whether the point (-2, 1) satisfies the inequality
When we subsitute the given point into given inequality, values in both sides of inequality must satisfy the condition
Let us substitute the given point (x, y) = (-2, 1) in given inequality
6(-2) + 1 > -11
-12 + 1 > -11
-11 > -11 which is not true, Since -11 is equal to -11
So the given point does not satisfy the inequality
Please note translations are just movements on a axis, they are not changing the length of a segment at all. In fact, only dilations change the figure. The length of E'F' is going to be the same as the length of EF.
You can multiply the second equation by -2
-5x + y = 15 everything by -2
10x - 2y = -30
now you can solve them
2x + 2y = -6
10x - 2y = -30
y cancels
2x= -6
10x = -30
12x = -36
/12. /12
x = -3
now to solve for y you substitute x for -3
-5(-3) + y = 15
15 + y = 15
-15 -15
y= 0
