Answer:
-7/3
Step-by-step explanation:
substitute 3
w(3)=-2(3)-1
3w=-6-1
3w=-7
divide by 3
w=-7/3
-1 because -3x+1=2 (4 total spaces) so,
2+1 is 3
you have life numbers and x values separate.
divide positive 3 by negative 3 to get -1.
check your answer by plugging it in
-1*-3 is 3
so - 3+1 world be 4 which is where the 2 is on the number line because it goes into negatives
answer is x= -1
What he has left in the bank is here :
(123.17 + 34.68) - 50 = 107.8
He still has $107.8 left in the bank and he has $50 in his pocket.
I hoped I helped!

Step-by-step explanation:
Answer:
C 200
Step-by-step explanation:
It does not appear to be LINEAR so
Start with :
pulse rate = y = 73e^kx
sub in x = .7 when y = 155
155 = 73 e^(.7 * k)
ln ( 155/73) = .7k
.75296567 = .7k
k = 1.07567
for x = 0.9 :
pulse rate = y = 73 e^(1.07567 * .9) = ~ 192 so I expect answer is 200
