Answer: 16.09
Step-by-step explanation:
Because you need to add it says total that means add
It will be a J-shaped graph. As X increases, Y will increase at a sharper rate, so it will look exactly like a J when graphed
Answer:
1
Step-by-step explanation:
If you are just looking for the derivative, then all you need to use the power rule for this. Technically the x in (x-9) has a power to the 1, so really x^1-9. To use power rule, you bring down the exponent, in this case, 1, and then minus 1 from what the exponent was.
1x^(1-1) = 1x^0. The derivative of any constant is 0, so don't even worry about the -9. We know that anything raised to the zero is just 1, so in this case your answer is 1.
Hope this helps :)
Answer:
$ 158.95
Step-by-step explanation:
Reduction = 25% of 199
= 0.25 * 199
= $ 49.75
Price of the tablet after reduction = 199 - 49.75 = $ 149.25
Sales tax = 6.5% of 149.25
= 0.065 * 149.25
= $ 9.70
Total price that he need to pay = 149.25 + 9.70
= $ 158.95
Answer:
x < 4
Step-by-step explanation:
-8x + 2x - 16 < -5x + 7x
Put the <em>x </em>values together on both sides.
6x - 16 < 2x
Subtract the <em>6x</em> from both sides.
-16 < -4x
Divide the <em>-4x</em> from both sides.
4 > x
<u><em>(NOTICE:</em></u><em> The inequality sign flipped when we divided by a NEGATIVE number. This will always happen when multiplying or dividing by a NEGATIVE)</em>
<em />
<em>Most teachers will want the variable in front so the answer will be </em><em>x < 4</em>
<em>(</em><u><em>NOTICE:</em></u><em> The inequality sign flipped again! This happens whenever you flip the order of the numbers. Meaning, the variable on the left or right side. Usually, you will want the variable on the left side.)</em>
