Answer:
$163
Step-by-step explanation:
Bob worked 26 hours and earn $7 per hour. Multiply 26 with 7:
26 x 7 = 182
Bob made a total of $182 last month.
Bob then spent $19. Subtract 19 from the total earned:
182 - 19 = 163
Bob has $163 left.

I do believe it would be x=30
Answer:
-2 =y
Step-by-step explanation:
-12 = 2 + 5y + 2y
Combine like terms
-12 =2+7y
Subtract 2 from each side
-12-2 = 2+7y-2
-14 = 7y
Divide each side by 7
-14/7 = 7y/7
-2 =y
Answer:
$3027.80
Explanation:
The compound interest formula is the following.

where
A = final amount
P = principle amount
r = interest rate / 100
n = number of compounds per interval
t = time interval
Now in our case,
A = unknown
P = $1900
r = 10.4/100
n = 12 months / year ( because the interest is compounded monthly)
t = 4.5 yrs
Therefore, the compound interest formula gives

Using a calculator, we evaluate the above to get

which is our answer!
A negative average rate of change means that as x increases, y decreases. That means that the graph goes down to the right.
