It looks like the given equation says
When <em>x</em> = 0, you have
Differentiating both sides with respect to <em>x</em> gives
That is, the derivative operator distributes over sums, and the derivative of a constant is 0; apply the product rule on the first term and chain rule on the second; then use chain rule one more time.
Now plug in <em>x</em> = 0 and <em>y</em> = 5, and solve for <em>y'</em> :
Answer:
0.45
Step-by-step explanation:
Percentages are the number over 100 which is basically 45/100. This fraction can be converted into a decimal, as the decimal places are 0.(tenths 1/10)(hundredths 1/100). 45 going into the hundredths puts the 4 in the tenths and the 5 in the hundredths.
Let the number be x.
2x + 15 = x + 23 | 15 added to 2x is equal to x increased by 23
x + 15 = 23 | Take away x from both sides
x = 8 | Take away 15 from both sides
Answer: The number is 8.
Assume that the number is n.
sum of twice the number and 15 means that you will first multiply the number by 2 then add 15.
the equation us:
2n + 15 = -42
2n = -42-15
2n = -57
n = -28.5
