Answer: (-2, -2)
Step-by-step explanation:
We will graph the equations. Then, we will decide which of the points is a solution. See attached for the graph. The point of intersection is the solution. This means the only solution is,
(2, 2)
Answer:
the first one im pretty sure
Step-by-step explanation:
Answer:
11 dollars
Step-by-step explanation:
First, we take 2 3/4 and make it a decimal: 2.75
We know one pound is 4 dollars, so 2.75 pounds of avocados would be 4 times 2.75 - 11 dollars.
Hope this helps!!! <3
The 3rd one because 0.12 is 0.120 0.34 is 0.340 0.695 is 0.695 and 0.9 is 0.900 its all in order
<span>A quadratic equation of the form ax^2 + bx + c has a general solution of the form
x = - b +- b^2 - 4ac/2a
We shall use the expression under the radical in the formular method. The expression under the radical is called the discriminant.
If the discriminant D = b^2 - 4ac > 0 then the quadratic has two distinct real number solutions since the square root of any positive number is it self a positive number.
If D = b^2 - 4ac = 0 then we get expressions of the form (-b + 0) and (-b - 0). Regardless we end up with -b. This means when D = 0 we have one solution.
If D < 0 the quadratic equation has a conjugate pair of complex roots of the form a + bi</span>
