Answer: -1

Step-by-step explanation:

In order to find the slope, you should remember the formula (Y1-Y2)/(X1-X2) the order of the x and ys do not really matter, but the they should be the same for the top and bottom. In this situation, you can do (4-6) which represent your Y1 and Y2 and then divide by (1 minus -1) which are your xs, this simplifies to -2/2 or simply, a slope of -1

Answer:

c. In 2 seconds, the commuter train travels 120 feet.

Step-by-step explanation:

Given

The attached graph

Required

What does x-coordinate of 2 represents

Represent this coordinate with (x,y)

From the graph:

x = 2 when y = 120

Note that:

x = time and y = distance

So:

(x,y) = (2,120)

Which means:

At 2 seconds, the train has travelled a distance of 120ft

<em>From the list of options, (c) is correct</em>

For the following exercises, evaluate the function f at the values f(−2), f(−1), f(0), f(1), and f(2)
MatroZZZ [7]

Answer:

See below.  <u><em>I assume that (x) = 8x2 - 7x + 3 is really (x) = 8x^2 - 7x + 3</em></u>

Step-by-step explanation:

Substitute the value of x given in f(x) into the equation f(x) = 8x^2 - 7x + 3

For example, f(0) would be f(0) = 8(0)^2 - 7(0) + 3.  f(0) = 3

f(-2) would be f(-2) = 8(-2)^2 - 7(-2) + 3.  

                                =   8*4  + 14 +3

                                = 32 + 17        therefore      f(-2) = 49

Solve similar triangles (advanced)
SCORPION-xisa [38]

Answer:

  x = 9/4

Step-by-step explanation:

Locate point G on segment DE so that DG = 1 and GE = 4. CG is parallel to AD, so ΔCGE ~ ΔABC. Corresponding sides are proportional.

  AB/BC = CG/GE

  x/1 = 9/4

  x = 9/4

_____

<em>Additional comment</em>

Using the given triangles, you can write the proportion statement as ...

  (9+x)/x = 5/1

We judge this to take more steps to solve, so we prefer the method shown above.
