What are the zeroes of the function y=3(x-a)(x+b) in terms of a and b?

Mathematics
1 answer:
juin [17]3 years ago
4 0

Answer:

a, -b

Step-by-step explanation:

When x is a, the function becomes

f(a)=3(a-a)(a+b)

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

f(-b)=3(-b-a)(-b+b)

As you see -b+b is 0, and once again, this would make the whole function 0.

Round 23.2736 to the nearest thousandth​
alekssr [168]

Answer:

23.274

Step-by-step explanation:

Here, rounding to the nearest thousandth means rounding to the nearest 0.001.

Hence, due to the digit being rounded having a number larger than 5 after it (0.2736), it is rounded up.

what is the equation of the line that passes through (-2,-3) and is perpendicular to 2x-3y=6? ...?
sergij07 [2.7K]
The equation given in the question is

2x - 3y = 6
Dividing both sides of the equation by 3, we get
2/3 x - y = 2
y = 2/3 x - 2
Then, from the above equation we can tell that the slope of the line in the graph is 2/3. The slope of a line perpendicular to this slope will be - 3/2. The line also contains the points (-2,-3). 
Then, the equation of the perpendicular line will be
y = mx + b
- 3 = (- 3/2)(- 2) + b
- 3 = 3 + b
b = - 6
Then
y = (-3/2)x - 6
y + 6 = (- 3/2)x
2y + 12 = - 3x
3x + 2y = - 12
