So, we divide 1200 by 25 to find out how many words per minute he types. 1200 / 25 = 48 So, he types 48 words per minute. Now, we multiply this by 45 to find out how many words he can type in 45 minutes. 48 x 45 = 2,160 Joseph can type 2,160 words in 45 minutes!

Given that (2,8) is on the graph of f(x),find the corresponding point for the function -3/4 f(x)
yuradex [85]

Answer:

Corresponding point to (2,8) along -3/4 f(x) = ( -1.5 , -6 )

Explanation:

 When a graph f(x) is multiplied by a factor k, the points on the graph also changes by (kx, ky).

Here it is given that (2,8) is on the graph of f(x)

Now we need to find corresponding point to (2,8) along -3/4 f(x)

x - coordinate = \frac{-3*2}{4} =-1.5

y - coordinate = \frac{-3*8}{4} =-6

So corresponding point to (2,8) along -3/4 f(x) = ( -1.5 , -6 )

Which expression is represented by the diagram? ( Marked 1-4, I can't paste the question.)
wel

Answer:

-6-(-1)

Step-by-step explanation:

Since all the boxes are negative, and there are 6 boxes, the first part of the equation is -6.  Then since the last box is being taken away, we are subtracting it.  The last box is still negative though so the last part is -1.  Since -6 subtracted by -1 is -6-(-1), the answer is:

-6-(-1)
