3x + 3(3x + 17) = -9
3x + 9x + 51 = -9
12x + 51 = -9
12x = -60
x = -5
Answer:
The equation of this line would be y = -8
Step-by-step explanation:
Since y = 9 is a horizontal line, the parallel line must also be horizontal. All horizontal lines can be written as y = (a number). That number can be found as the y-coordinate in the ordered pair, which is -8.
y = -8

Answer:
407.22 foot is the boat from the base of the lighthouse
Step-by-step explanation:
Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.
Let x foot be the distance of the object(boat) from the base of the lighthouse
Angle of depression =
[Alternate angle]
In triangle CAB:
To find AB = x foot.
Using tangent ratio:
Here, BC = 50 foot and
then;
or
Simplify:
AB = x = 407.217321 foot
Therefore, the boat from the base of the light house is, 407.22'
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled. The value of x will be 85.
<h3>What is a relative frequency table?</h3>
A relative frequency table is a graph that depicts the popularity or pattern of a certain piece of data based on the population sampled.
When we examine the relative frequency, we examine the number of times a certain event happens in comparison to the overall number of events.
We have the following equation for the adult column;
Hence the value of x will be 85.
