Csc(60) -4 cot (-45) sin (330)
I think they mean how to make it an improper fraction. My guess would be 7 over 1, but I could be wrong.
Answer:
No
Step-by-step explanation:
The first coordinate is x and the second is y so that makes the equation 3=6 which is not true.
Let's call the two numbers a and b. So we know that the difference of the two numbers is 36:
a - b = 36
And we know that their sum is 286:
a + b = 286
We can use either of these equations to solve for one of the variables in terms of the other variable. Let's use the first and solve for a:
a - b = 36
a = 36 + b
Now we plug this into the other equation and solve for b there:
(36 + b) + b = 286
36 + 2b = 286
2b = 250
b = 125
Answer:
a)
(x,y)
(-2,-3),(-1,0),(1,-4),(2,-3),(3,0),(4,3)
b) A
c) -1.75
just substitute the number in.
d) quadratic formula used
x=3.2
x= -1.2
