Answer = 150 minutes
So 1 class has 50 minutes
Addition way )
50 + 50 + 50 = 150 minutes
multiplication way )
50 * 3 = 150 minutes
make the equation slope-intercept form:
subtract 2x from both sides:
4y = -2x + 12
divide by 4 to get y by itself:
y = -1/2x + 3
to make the new line perpendicular to the existing line, completely flip the slope of the line:
y = 2x + 3
Answer:
None of these statements are true.
Step-by-step explanation:
a) The derivative of (fg)(x) is f'g +fg' according to the product rule for derivatives.
__
b) The derivative of |x² +x| is a 3-part piecewise linear function equal to 2x+1 for |x+1/2| > 1/2, and equal to -2x-1 for |x+1/2| < 1/2. It is undefined for x=0 and x=1.
__
c) for y = √f(x), y' = f'(x)/(2√f(x))
109.31
To find this you can convert 58% to decimal form, which is .58. Once you have a decimal form of a percent, you can multiply it by the number you are taking the percent of and get an answer. So .58 times something equals 63.4. You can write this as an equation:
.58x = 63.4
and solve for x, which would get 63.4/.58, which equals 109.31.
