IRINA_888 [86]3 years ago
4 0

Answer:

  y +3 = -6(x +9)

Step-by-step explanation:

The point-slope form of the equation of a line is ...

  y -k = m(x -h)

for a line with slope m through point (h, k).

You want the line with slope -6 through point (-9, -3), so its equation is ...

  y -(-3) = -6(x -(-9))

  y +3 = -6(x +9) . . . . . matches the last choice

Answer:

The given expression is written as 5^{1+a}

Step-by-step explanation:

Given as :

The expression is written as  x = 5^{a}

Now foe 5 x , the expression is written as

5^{1} × 5^{a}

Now <u>from base indices method </u>

Level, x       1      0.8    0.65
time, y        0        1       2

The graph is not a straight line, it is curved. You can observe this only if you include the point (1,0), which is the level at the begining (100%)

The y - intercept is the full level, at the beginning of the experiment.

Calculate the mean for each set of data.<br>a 12, 18, 9, 14, 8, 7​
Vinil7 [7]

Answer:

11.3, rounded

Step-by-step explanation:

mean = average. Add them all up, then divide by how many entries/data points you have.

12 + 18 + 9 + 14 + 8 + 7 = 68

There are 6 numbers we added, so 68/6 = 11.3333333

<h3>Answer:  53/108</h3>

======================================================

Explanation:

  • Step 1) add up all the values in the circles "drama" and "music". Those values are 51, 15, 12, 11, 7, 63. So we get 51+15+12+11+7+63 = 159. There are 159 students that are in drama, music, or both. Some take athletics as well, but we aren't concerned with that third class.
  • Step 2) Divide 159 over the total number of juniors, which is 324. We get 159/324.
  • Step 3) Reduce the fraction 159/324 to get the answer 53/108. You would divide both parts of 159/324 by the GCF 3. So we have 159/3 = 53 and 324/3 = 108

If you want the decimal approximation, then use a calculator to get roughly 53/108 = 0.4907, though your teacher wants the exact fraction form.
