Answer:
5x+2y+z
Step-by-step explanation:
just count all of the variables
This is not a function. The input 7 in set A maps to outputs -1 and -3 at the same time in set B, which is why we don't have a function.
For a function to be possible, each input must map to exactly one output only.
Yes, it is faster. hope I helped
Answer:
y=7
Step-by-step explanation:
2x2=4 +3 =7 y
∠GBE = y (alternate angles)
∠DBG + ∠GBE = 180 (Adjacent angles on a straight line adds up to 180)
⇒ x + y = 180
∠DBG = ∠ABE (Vertially opposite angles)
⇒ x = 5y - 18
--------------------------------------------------
Solve for x and y :
--------------------------------------------------
x + y = 180 -------- (1)
x = 5y - 18 --------- (2)
Sub (2) into (1) :
5y - 18 + y = 180
6x = 198
x = 33 --------- Sub into (1)
x + y = 180
33 + y = 180
y = 147
-----------------------------------------------------
Answer: x = 33°, y = 147°
-----------------------------------------------------
