Answer:
(x,y)=(-2,-5)
Step-by-step explanation:
y=1/2x-4
y=-2x-9
(y=) 1/2x-4=-2x-9
1/2x +2x=-9+4
1/2x +4/2x=-5
5/2x=-5
5x=-5*2
5x=-10
x=-2
x=-2
y=-2x-9=-2*(-2)-9=4-9=-5
(x,y)=(-2,-5)

6c-7+d+4-6d=6c-5d-3
Answer:
thank you very much
Step-by-step explanation:
The domain (input values) of the cosine function is all negative and positive angle measures.
Let the function be f(x) = cos(x)
The domain of cos(x) is -∞ < x < ∞
The range is -1 ≤ f(x) ≤ 1
Hence, domain of cos(x) is all (+) and (-) angle measures.
Same goes with sine function as well
For function f(x) = sin(x)
The domain is -∞ < x < ∞ and range -1 ≤ f(x) ≤ 1
However for f(x) = tan(x) the same is not applicable.
Answer:
Area = Length × width
16 = (3x +2 ) × ( x)
16 = 3x² +2x
3x² +2x -16=0
( 3x+8 ) ( x -2 ) =0
3x +8=0 —> 3x = – 8 —> x = – 8/3 —> x = – 2.6
x-2=0 —> x = 2
I hope I helped you^_^
