.5 * .5 *.5 = 1/8
-
-
the probability to have head is .5 so the probability of tails 1-.5
-
then the first time is head
the second time is head
the third time is tail
so
.5 * .5 *.5 = 1/8
Y = 4 - x
3x + 4(4-x) = 14
3x + 16 -4x = 14
-x = -2
x = 2
y = 2
Answer:
Hope it helps!
Step-by-step explanation:
Sub y=5x into y=2x+3
so
5x=2x+3
3x=3
x=1
plug x=1 into y=5x
y=5
Checking work
Plug (1,5) into y=2x+3
5=2(1)+3
5=5
Plug (1,5) into y=5x
5=5(1)
5=5
