Strike441 [17]

Answer:

  • y + 2 = 5x

Step-by-step explanation:

<u>Point-slope form: </u>

  • <em>y - y1 = m(x - x1)</em>

<u>Slope formula:</u>

  • <em>m = (y2 - y1)/(x2 - x1)</em>

<u>Given points:</u>

  • (0, -2) and (3, 13)

<u>Finding the slope:</u>

  • m = (13 - (-2))/(3 - 0)
  • m = 15/3
  • m = 5

<u>Using point 1</u>

  • y - (-2) = 5(x - 0)
  • y + 2 = 5x

HELP ME PLEASE!<br><br> In triangle FGH, GH=1, FG=12, and GH=sq. root of 145
topjm [15]

Answer:

B&C: tan F=0.0833 & tan H=12.0000

Step-by-step explanation:

The tangent relationship is always opposite/adjacent.

When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.

1/12 is 0.0833

When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.

12/1 is 12.

Un vendedor de celulaes tiene una meta diaria de venta si al momento lleva el Q.2,000.00 de la meta que equivale el 20%
astra-53 [7]

Answer:

Sales goal, S = Q. 10,000

Step-by-step explanation:

  • Let the daily sales goal be S.

<u>Given the following data;</u>

  • Amount sold = Q. 2,000.00
  • Percentage of the sales goal = 20%

To find his daily sales goal;

\frac {20}{100} * S = 2000

0.2 * S = 2000

Dividing both sides by 0.2, we have;

S = \frac {2000}{0.2}

<em>Sales goal, S = Q. 10,000</em>
