Since the two integers are consecutive, we can let the first be x and the second be x+1. Then [x] + [x+1] = -225. Simplifying, 2x + 1 = -225, or
2x = -226. Thus, x = -113 and x+1 = -113+1 + -112.
The two consecutive integers are -112 and -113. Adding these together results in -225, as we had hoped.
Answer:
There are no real solutions
Step-by-step explanation:
Recall that for a quadratic equation in the form:
ax² + bx + c = 0
using the quadratic formula, that the discriminant of the formula is given by the following expression
Discriminant = b² - 4ac
If b² - 4ac < 0 ----> No real roots
If b² - 4ac > 0 ----> Two real roots
If b² - 4ac = 0 ----> One real roots
In our case, a = 3, b = -2 and c = 4
b² - 4ac = (-2)² - 4(3)(3) = 4 - 36 = -32 (which is <0)
Hence there are no real roots.
answer:
center: (-2, 0)
radius: 5
explanation
re write that equation in the form if the standard circle equation
(x - ( -2))^2 + (y - 0)^2 = 5^2
therefore the circle properties are: (a,b) = -2, 0 and the radius is 5
Answer: no solution
Good luck !
Answer:
-2 degrees Celsius
Step-by-step explanation:
Graph at 3 degrees Celsius as your starting point, then go down by 5 degrees Celsius on the number line.
3 - 5 = -2
-2 should be the Temperature at late in the afternoon.
