Answer:
Solution of equation :-
x = 1 or x = -4
Step-by-step explanation:
The given quadratic equation is x² + 3x - 4 = 0
<u>To find the solution</u>
<u>Using splitting method</u>
x² - x + 4x - 4 = 0
x(x - 1) + 4(x - 1) = 0 (take x and 4 as common)
(x - 1)(x + 4) = 0
(x - 1) = 0 or (x + 4)= 0
If x - 1 = 0 then x = 1
If x + 4 = 0 then x = -4
AB=DE is a true statement
Answer:
C
Domain: {-2, -1, 1, 3}
Range: {-4, 0, 4, 6}
Step-by-step explanation:
The domain is the set containing all x-coordinates.
Domain: {-2, -1, 1, 3}
The range is the set containing all y-coordinates.
Range: {-4, 0, 4, 6}
Answer:
C
Domain: {-2, -1, 1, 3}
Range: {-4, 0, 4, 6}
Answer:
-6
Step-by-step explanation:
Substitutet -7 for y in -3(9+y): -3(9 - 7) = -3(2) = -6
