Answer:
x = 93.4° ( to 1 dec. place )
Step-by-step explanation:
Given
cos(x - 46.7)° = 4 ( divide both sides by )
cos(x - 46.7)° = 
, thus
x - 46.7 = 
( ) ≈ 46.7° ( add 46.7° to both sides )
x ≈ 93.4°
Answer:
(1/4*d) + 8
Sorry but there's no explanation cause its quick
I think it is!
there are no points that are in the same x unit!
hope this help! :(

You subtract $56.75 from $87.37,which equals $30.62, then you add the 2 checks that the bank didn't return and subtract that amount from the $30.62.
Answer:
(-4, 2)
Step-by-step explanation:
4x+2y=-12
3x+y=-10
Start by dividing the first equation by 2 to simplify it...
2x+y=-6
Then, subtract -2x from both sides to isolate y...
y=-2x-6
Substitute -2x-6 for y in the second equation...
3x-2x-6=-10
Combine like terms...
x-6=-10
Add 6 to both sides
x-6+6=-10+6
x=-4
Plug -4 in for x to solve for y:
3(-4)+y=-10
-12+y=-10
Add 12 to both sides
-12+12+y=-10+12
y=2
(x,y)=(-4,2)
