Answer: a) 1:1
they are even. if it was 1:2 or 2:1 one of them on the graph would be taller but that are both at the same number
Answer:
x^2 – 4 = 0
Step-by-step explanation:
When x = - 2,
x^2 - 4 = 0
( - 2 )^2 - 4 = 0
4 - 4 = 0
When x = 2,
x^2 - 4 = 0
2^2 - 4 = 0
4 - 4 = 0
The answer is A because if X represents the # of packages sold on Monday, then Tuesday can be represented by x+4 and Wednesday by x+6. Add the three expressions to get 3x+10=28, subtract 10 from both sides. 3x=28, divide by 3 and get x=6
Answer:
WX=36
Step-by-step explanation:
2x+16=7x-29
45=5x
x=9
7x-29
7(9)-29
65-29
36
Answer:
y = (√3)/2
Step-by-step explanation:
The unit circle has equation ...
x^2 +y^2 = 1
For x = 1/2, the value of y can be found to be ...
(1/2)^2 +y^2 = 1
y^2 = 1 - 1/4 = 3/4 . . . . . subtract 1/4
y = √(3/4) . . . . . . . . . . take the square root (y > 0 here)
y = (√3)/2
