Answer:
It's the second graph on edge 2020
Step-by-step explanation:
Answer:
y= 9x -4
Step-by-step explanation:
Please see attached picture for full solution.
The integers here are 9 and -4.
There isnt a need to use fractions in this case and hence I did not write the integers into a fraction (e.g. -4 into
) since the question requires them to be in the simplest form.
Answer:
Option B is correct.
the value of discriminant is, -7
Step-by-step explanation:
Given the equation: ![x^2 + x +2 = 0](https://tex.z-dn.net/?f=x%5E2%20%2B%20x%20%2B2%20%3D%200)
To find the value of discriminant ![b^2-4ac](https://tex.z-dn.net/?f=b%5E2-4ac)
A quadratic equation is of the form
where a, b and c are coefficient of the equation.
On comparing with given equation we have;
a = 1 , b = 1 and c = 2
then;
Discriminant = ![b^2-4ac =(1)^2 -4(1)(2) =1 -8 = -7](https://tex.z-dn.net/?f=b%5E2-4ac%20%3D%281%29%5E2%20-4%281%29%282%29%20%3D1%20-8%20%3D%20-7)
Therefore, the value of discriminant is, -7
A four-inch part is connected around the hot water heater as to expand. So d = 20 + 4 + 4 = 28 inches.
The area of a circle is A = <span>π(d/2)^2
A = </span><span>π(28/2)^2 = 3615.7521... inches = 3620 inches (rounded to the nearest tenth)</span>
