What is the equation of the line that passes through the point<br> (5,-2) and has a slope of 6/5
LenKa [72]

Answer:

y = \frac{6x}{5} - 8

Step-by-step explanation:

given slope m = \frac{6}{5}

point (5, -2) for (x1, y1)

equation for point slope form

y - y1 = m(x- x1)

y - (-2) = \frac{6}{5} (x -5)

y + 2 = \frac{6}{5}x - 6, simplify

y = \frac{6x}{5} - 8,

further you can multiply by 5 to get rid of fraction

5y = 6x - 40

What are the 3 angle measures in the triangle shown below
7nadin3 [17]

9514 1404 393

Answer:

  B.  39°, 106°, 43°

Step-by-step explanation:

The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.

  (3x +1) +(11x -4) +(5x -7) = 180

  19x -10 = 180 . . . . . collect terms

  19x = 190 . . . . . . . . add 10

  x = 10 . . . . . . . . . . . divide by 19

__

Then the three angle measures are ...

  • 3·10 +1 = 31
  • 11·10 -4 = 106
  • 5·10 -7 = 43

The appropriate choice is ...

  B.  31°, 106°, 43°

A contractor is building the base of a circular fountain. On the blueprint, the base of the fountain has a diameter of 18 centim
Daniel [21]
The answer is 1808.64 ft²

To calculate area of square we need to find radius r. Radius is a half of a diameter:
r = d/2

The blueprint:
d = 18 cm
r = 18/2 = 9 cm

<span>The blueprint has a scale of three centimeters to four feet. Actual radius r1 is:
</span>3 cm : 4 ft = 18 cm : r1
After crossing the products:
r1 = 4 ft * 18 cm : 3 cm
r1 = 24 ft

The area of the circular base of the fountain is:
A = r1² * π
π = 3.14
r1 = 24 ft

A = 24² * 3.14
A = 1808.64 ft²
