What is the value of x?
nalin [4]

Answer:

  x = 42.9 m

Step-by-step explanation:

Corresponding sides of similar triangles MAB and MNP are proportional. This means ...

  x/MP = MA/MN

However, we don't have a number for MA yet, so we need to find it.

  MA +AN = MN

  MA = MN - AN            subtract AN

  MA = 67.2 m - 32 m = 35.2 m

Now, we can use this to find x.

  x = MP · (MA/MN) = (81.9 m) · 35.2/67.2

  x = 42.9 m

For the line represented by y = 5 x − 7, the slope is ________ and the
Dmitry_Shevchenko [17]

Answer:

For the line represented by y = 5 x − 7, the slope is 5 and the

y-intercept is -7.

Step-by-step explanation:

The equation is in <em>Slope-intercept form</em>.

y=mx+b

The letter 'm' represents the slope.

The letter 'b' represents the y-intercept.

In the equation y=5x-7:

  • 5 is the slope because it replaces 'm' in the equation. The 'm' is the slope.
  • -7 is the y-intercept because it replaces 'b' in equation. The 'b' represents the y-intercept.
