We are given with two solutions: y = x2 + 12x + 30 and 8x – y = 10 and is asked to determinte the solutions of the system of equations. We get y in the second eqn which is equal to 8x -10. we substitute this to first eqn resulting to
8x-10 = x^2 + 12 x + 30. this is a second order equation. x is equal to -2 + 6i and -2 - 6i.
I feel like it would be 5/12, but im not 100% sure
Answer:
<em>3.2 units</em>
Step-by-step explanation:
Find the distance between points P(9, 2) and Q(6, 1) to the nearest tenth.
The distance between two points is expressed as;
D = √(x2-x1)²+(y2-y1)²
D = √(1-2)²+(6-9)²
D = √(-1)²+(-3)²
D = √1+9
D = √10
<em>Hence the distance between the two points is 3.2 units</em>
Answer:
True
Step-by-step explanation:
6x² - 4y - 3x + 6x² + 8x = 12x² + 5x - 4y
Regroup terms on left
6x² + 6x² - 3x + 8x - 4y = 12x² + 5x - 4y
Combine like terms
on left
12x² + 5x - 4y = 12x² + 5x - 4y True
