Answer:
x=-11
Step-by-step explanation:
-9x-4-8+7x=10
-2x-12=10
+12 +12
-2x=22
-2x/-2=22/-2
x=-11
The points that lie on function h (x) = 3x² is, " (1, 3) and (-1, 3)".
You can put the values in to the equation of the abscissas of the ordered pair and solve for h(x)
A. (1, 3) ; h(x) = 3(1²) = 3 Equal B. (-1, 3) ; h(x) = 3(-1)² = 3 EqualThus, these are the points that lie on function h(x ) = 3x²
If two secants are drawn from a point lying outside a circle, then the product of one secant on its outer part is equal to the product of the other secant on its outer part.
DE*CE = AE*BE
DE = CD + CE = 1 + x + 4 = x + 5
AE = AB + BE = 11 + x + 1 = x + 12
(x+5)(x+4)=(x+12)(x+1)
x² + 4x + 5x + 20 = x² + x + 12x + 12
9x + 20 = 13x + 12
20 - 12 = 13x - 9x
8 = 4x
x = 8/4
x = 2
Yes. 1/1 is a fraction but it can be simplified to 1 which is a whole number.
