Answer:
4 or -4 !
Step-by-step explanation:
edit... isolate the variable, so divide 5 on both sides. then take the absolute value of d which is d. therefore d = 4 or -4! it's both positive and negative because absolute value you set it equal to a positive and negative!
Answer:
x = 7, y = 30 and x = 3, y = 10
Step-by-step explanation:
5x - y = 5, then y = 5x - 5
2y - x^2 = 11
2(5x - 5) - x^2 = 11
10x - 10 - x^2 = 11
-x^2 + 10x -10 = 11
-x^2 + 10x -21 = 0
x^2 - 10x + 21 = 0
(x - 7)(x - 3) = 0
x = 7, y = 30
x = 3, y = 10
Answer: Graph A
We can determine the x-intercepts from the equation. X-intercepts are x=-2 and x=-7 which is what Graph A shows.
Answer:
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
A die has 6 sides, in which 3 numbers (2 , 4 , 6) are even.
Simplify: 3/6 = 1/2
There is a 1/2 chance that blue is even and green is even.
