Answer:
x = 6, -8
Step-by-step explanation:
If (x - 6)(x + 8) = 0, that would imply that either (x - 6) or (x + 8) would equal zero. Using this, we can find that solving the two equations:
x - 6 = 0
and
x + 8 = 0
would yield the two solutions to the equation.
x - 6 = 0
Add 6 to both sides of the equation.
x = 6
So one of the solutions would be x = 6.
x + 8 = 0
Subtract 8 from both sides of the equation.
x = -8
So the other solution would be x = -8.
The two solutions are x = 6 and x = -8.
I hope you find my answer and explanation to be helpful. Happy studying.
A triangle ABC is similar to a triangle A´B´C´ The scale factor of the dilatation : s.
0 * s =0
4 * s = 10
6 * s = 15
s= 10/4=15/6=2.5
The scale factor of the dilatation is 2.5. It is shown in the attachment.

ANSWER
x=3, y=-4
EXPLANATION
The given system is :
First equation:
Second equation:
Let us multiply the first equation by 7 to get,
Third equation;
Let us multiply the second equation too by 10 to get,
Fourth equation:
Subtract the fourth equation from the third equation:
Divide both sides by 59.
Put y=-4 into the second equation and solve for x.
The solution is x=3, y=-4
