Step-by-step explanation:
B²-4ac?
<span>5x²+7x-6 = 0 </span>
<span>the form is ax²+bx+c = 0 </span>
<span>a=5, b=7, c=-6 </span>
<span>The discriminant D = b²-4ac </span>
<span>= 7² - 4(5)(-6) = 49 + 120 </span>
<span>= 169 </span>
Step-by-step explanation:
I've used substitution method over here and got the value of X and Y
Answer:
A’ (6,-2)
B’ (1,3)
Step-by-step explanation:
Here, we want to give the coordinates after a counterclockwise rotation of 90 degrees
Given a point with coordinates (x,y)
A counterclockwise rotation at 90 degrees to the origin will yield the coordinates (-y,x)
So A (-2,-6) will be A’ (6,-2) while B (3,-1) will be B’ (1,3)
