Answer: k=9/4
Step-by-step explanation: We can do this by finding a number that adds up to 3 when multiplied by 2. The best way to do this is to use ((b^2)/4) which can usually find you the number for a perfect square based on b, which we have. So, 3^2 / 4 =9/4, meaning k=9/4. We can check:
>x^2 +3x +9/4
> (x+3/2)(x+3/2)
Perfect square.
Answer:
The equation of the line will be:
Step-by-step explanation:
Given the points
Finding the slope between (3, 4) and (12, 9)
The equation of the line can be obtained using the point-slope form of the equation of the line
substituting the values m = 5/9 and the point (3, 4)
Therefore, the equation of the line will be:
Cost of 380 gram of sweets = (2.1/50) * 380 = $15.96
Answer:
a) the initial value is $125, and it represents the cost Navin has to pay in the beginning
b) the rate of change is $20 per month, and it represents the cost he has to pay per month
c) linear; the equation for it is y = 20x + 125
d) The rate of change is constant because each month, Navin always has to pay $20.
e) This is <u>partial variation</u> because the equation y = 20x + 125 doesn't follow y = kx
