Answer:
-14+77=63
21-82=-61
|-61|=61
So 63-61=2
Step-by-step explanation:
Answer:
k = 2
Step-by-step explanation:
Given the equations:
g(x) = 3x² + 8x + k
f(x) = 2x - 1
At the intersection point:
g(x) = f(x)
3x² + 8x + k = 2x - 1
3x² + 6x + (k+1) = 0
If there is only one intersection point, the discriminant must be equal to zero:
b² - 4(a)(c) = 0
6² - 4(3)(k+1) = 0
36 - 12(k+1) = 0
36 - 12k - 12 = 0
24 = 12k
24/12 = k
2 = k
Answer:
6 units
Step-by-step explanation:
distance between (-2,-2) and (4,-2)
distance formula,
√(x2-x1)²+(y2-y1)²
x2=4
x1=-2
y1=-2
y2=-2
putting the values,
√(4+2)²+(-2+2)²
√6²+0²
6 units
The domain of the inside function exists, and then an analysis of the outside function may yield an extra restriction to the domain.
Answer:
Its the second option. 742.5
