Answer:

2. \frac{1}{4}

Step-by-step explanation:

For 2. I multiplied the denominator by the whole number and added the numerator

3\frac{1}{5}

5 x 3 = 15 + 1 = 16 and with that u get your improper fraction \frac{16}{3}.

Then, you make 12 improper by making it  \frac{12}{1}

Then you multiply by the recirprocal (which means you flip the fraction around)

\frac{3}{16} / \frac{1}{12}

Which graph represents the function f(x)=−3x−2?
LenaWriter [7]

Answer:

Top left

Step-by-step explanation:

We can plug in the y intercept to find which graph has the correct one.

x = 0 is y intercept

Thus

f(0) = -3^0-2 \\f(0) = -1-2\\f(0)=-3

At this point we known the y intercept is -3 so both graph in the left is considerable.

Notice that the base is the negative, thus the graph would goes down. Therefore the top left would be correct.

How to solve number b
Mkey [24]
You're on the right track. If they generated 380 less than 2012, then in 2013 they generated 9782-380 = 9402.
They used 10472 in 2012, so 10472+390 = 10862 used in 2013. now subtract used from produced to see how much they had to buy...
10862-10472 = 390
They had to buy 390khW from the power company.

(u*v)'=u'v+uv'
u=2x²+3 ==> u'=4x
v=sin 5x ==>v'=cos 5x *5

((2x²+3 sin (5x))'=4x* sin (5x) +(2x²+3)*cos (5x) * 5
