s(4) This means that t = 4, so you can plug in 4 for "t" in the equation
s(t) = 9t - 4
s(4) = 9(4) - 4
s(4) = 36 - 4
s(4) = 32
(4 , 32) This is the point on the graph. To graph it, each unit/square can be 4 [so go by 4's]
Answer:
j+1
Step-by-step explanation:
j/k + 1/k = ?/k
Since the denominator is the same, we can add the numerators
j/k + 1/k = ?/k
(j+1)/k = ?/k
Answer:
Last year the cost was $28.
This year the cost is $36.
$36 - $28 = $8
Percent of increase = amount of increase ÷ original amount
$8/$28 = $0.286
$0.286 · 100 = 28.6%
There has been a 28.6% of change in the cost.
Answer:
Step-by-step explanation:
Somebody plays 30 times
L+W = 30, where L and W are number of losses and wins, respectively.
L = 30-W
Net after 30 plays is $6
2W - 1L = 6
2W - (30-W) = 6
3W = 36
W = 12
W = 18
17 wins
