Answer:
y = -1x + 6 or y = -x + 6
Step-by-step explanation:
First, let's identify what slope-intercept form is.
y = mx + b
m is the slope. b is the y-intercept.
We know the slope is -1, so m = -1. Plug this into our standard equation.
y = -1x + b
To find b, we want to plug in a value that we know is on this line: (2, 4). Plug in the x and y values into the x and y of the standard equation.
4 = -1(2) + b
To find b, multiply the slope and the input of x(2)
4 = -2 + b
Now, add 2 from both sides to isolate b.
6 = b
Plug this into your standard equation.
y = -1x + 6
This is your equation.
Check this by plugging in the point again.
y = -1x + 6
4 = -1(2) + 6
4 = -2 + 6
4 = 4
Your equation is correct.

Submarines use sonar systems, which are similar to radar systems, to detect obstacles. Sonar systems use sound to detect objects underwater.
a. You are traveling underwater in a submarine. The sonar system detects an iceberg 4000 meters ahead, with an angle of depression of 34∘ to the bottom of the iceberg. How many meters must the submarine lower to pass under the iceberg?
The submarine must lower at least ____ meters.
Question 2
b. The sonar system then detects a sunken ship 1500 meters ahead, with an angle of elevation of 19∘ to the highest part of the sunken ship. How many meters must the submarine rise to pass over the sunken ship?
The submarine must rise at least ____ meters.
Answer:
a. tan(34)= O/4000 and follow the solving to get the distance it must be lowered
b. (Same idea as a) tan(19)=1500/A and solve to get the distance
The submarine must lower at least 2698 meters and the submarine must rise at least 516.45 meters.
Given that, the sonar system detects an iceberg 4000 meters ahead, with an angle of depression of 34∘ to the bottom of the iceberg.
What are trigonometric angles?Trigonometric angles are the angles in a right-angled triangle using which different trigonometric functions can be represented. Some standard angles used in trigonometry are 0º, 30º, 45º, 60º, 90º.
a) We know that, tan θ = (Perpendicular/Base)
Let the number of meters must the submarine lower to pass under the iceberg be x.
tan θ = x/4000
⇒ tan 34° = x/4000
⇒ 0.6745 = x/4000
⇒ x = 0.6745 × 4000
⇒ x = 2698 meters
b) Let the number of meters must the submarine rise to pass over the sunken ship be y.
tan θ = y/1500
⇒ tan 19° = y/1500
⇒ 0.3443 = y/1500
⇒ y = 0.3443 × 1500
⇒ y = 516.45 meters
Therefore, the submarine must lower at least 2698 meters and the submarine must rise at least 516.45 meters.

Can you please help me solve for x for this triangle please!!
Answer:
See below, please!
Step-by-step explanation:
Since this triangle is a right triangle, the two acute angles are always going to be complementary (adding up to 90 degrees). So we can set up an equation: 2x+3x+5=90. Solve this and we get x=17.

Write the equation of the line in fully simplified slope-intercept form?
Answer:
y=-[tex]\frac{1}{2}[/tex]x+1
Step-by-step explanation:
So the first number after the y= is the slope which is - 1/2 then you add an X after that. Then you add the y-intercept point which on this graph is 1.
Which proportion can be used to find the arc length, s, in units?
Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = [tex]\frac{150}{360}(2\pi )(42)[/tex]
[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]
[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]
Therefore, Option B will be the answer.

Rewrite this expression without using absolute value
I nEeD hElP qUiCk!
Answer:
Step-by-step explanation:
Normally when you are doing an absolute value question, you do it like this
y = abs(4x - 12) and you write the absolute value equation as
y = 4x - 12 and
y = - 4x + 12
These two are shown in graph27a
to show both wings of the absolute value curve
This is slightly different.
I think you would write this as
y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b
