Answer:
The answers to your questions are given below
Step-by-step explanation:
A. 3 × 9 = 27
B. 2 × 3 × 9 = 54
Next, we shall determine which option will give the same result obtained above.
9 × 3 = 27
9 × 3 × 2 = 54
3 × (4 + 5) = 3 × 9 = 27
(2 × 3) × 9 = 6 × 9 = 54
Therefore,
3 × 9 = 27
9 × 3 = 27
3 × (4 + 5) = 27
2 × 3 × 9 = 54
9 × 3 × 2 = 54
(2 × 3) × 9 = 54
SUMMARY
3 × 9 >>>>>>>>> 2 × 3 × 9
9 × 3 >>>>>>>>> 9 × 3 × 2
3 × (4 + 5) >>>>> (2 × 3) × 9
Answer:
(- 2, - 9 )
Step-by-step explanation:
The axis of symmetry passes through the vertex of the parabola.
Thus the x- coordinate of the vertex is x = - 2
To find y substitute x = - 2 into f(x)
f(- 2) = (- 2)² + 4(- 2) - 5 = 4 - 8 - 5 = - 9
Vertex = (- 2, - 9 )
You can do trial and error to all of the choices. They are presented as coordinates (x,y). Just substitute the x and y values, then if they satisfy the equation, then that is the answer. Among the choices, the answer would be B. Here's why:
x = 3, y = 4
2(3) + 4 > 8
10 > 8 TRUE
3 - 4 < 2
-1 < 2 TRUE
Thus, the answer is B.
Answer:
47.5! Ask if you wanna know how exactly i got this and the formulas!
Step-by-step explanation:
3 x 5 = 15
<em>15 / 2 = 7.5</em>
<em>5 x 5 = 25</em>
14 - 8 = 6
6 x 5 = 30
<em>30/2 = 15</em>
<em></em>
<em>7.5 + 25 + 15 = 47.5</em>
Answer:The answer would be 3/12 and 5/12 Because 4×3 = 12
