Answer:
1/2 x^2 + 2x - 6 = 0
(1/2 x - 1)(x + 6) = 0
zeroes are 2 and -6
so the graph intersects x axis at -6 and 2
The only one to do that is diagram A
Step-by-step explanation:
Answer:
B) -9
Step-by-step explanation:
31+2= 33 --> -33 + 49= --> 16
-5x-5= 25
16 -25 = -9
To split this trinomial into two binomials, let's try and find two numbers which add to 6 and multiply to 8. To do this, we can list all the factors of 8 and then choose which factors also add to 6.
Factors of 8: (1, 8), (2, 4)
1 + 8 = 9, meaning that 1 and 8 are not the factors we are looking for. However, 2 and 4 do add to 6. By combining these numbers which an x (so that we can produce the
term at the front of the trinomial), we find the binomials:
and 
The answer is x + 2 and x + 4.
Y=x+2 solve for x and then reverse labels...
y-2=x so
y=x-2
f^-1(x)=x-2 is the inverse of f(x)=x+2
you can just split the figure in 2 separate figures and them add the areas:
area rec. 1:
3m×3m= 9m²
area rec. 2:
3m× (2m+3m)
= 3m×5m
=15m²
total area:
9m²+15m²= 24m²
