Amount in the bank account = 1000(1 + 0.05)^5 = $1,276.28
Answer: C, 7s + 3t and 3t + 7s.
Step-by-step explanation: Nothing is changing between the expressions except for their position. In addition, position does not matter though, so these two are the SAME EXPRESSION
The answer is b because all you have to do is just subtract if I am wrong so sorry
Answer:
8X2-38X-380
Step-by-step explanation:
(2x+10)(4x-38)
Expand the brackets.
2X(4X-38)+10(4X-38)
Multiple the inner ones by the outer ones
(2X)(4X)-(38)(2X)+(10)(4X)-(10)(38)
=> 8X2-78X+40X-380
8X2-38X-380
Answer:
f(x) = 12x = 10
Step-by-step explanation:
We need a linear equation in the slope-intercept form.
y = mx + b
where y = total pay, m = hourly salary, x = number of hours worked, and b = y-intercept, or initial value
Let's look in the table.
1 hour: $22
2 hours: $34
The difference in pay between 1 hour and 2 hours is $34 - $22 = $12.
The difference in time between 1 hour and 2 hours is 1 hour.
In 1 hour he earns $12. That means the slope is 12.
We know he earns $22 for working a total of 1 hour.
Start at 1 hour and $22 on the table.
Subtract 1 hour from 1 hour to get 0 hours.
Subtract $12 form $22 to get $10.
That means for 0 hours he gets $10. b = 10
The equation is
y = 12x + 10
In function form, we have:
f(x) = 12x = 10
