Answer:
Let's solve for x.
−2(x+3y)=18
Step 1: Add 6y to both sides.
−2x−6y+6y=18+6y
−2x=6y+18
Step 2: Divide both sides by -2.
−2x/−2
=
6y+18
−2
x=−3y−9
Answer:
−3y−9
Slope = ∆y/∆x
= (8 -(-5))/(-5-5)
= 13/-10
= -1.3
The slope of the line through the given points is -1.3.
Answer:
4
Step-by-step explanation:
5 + 3/1 + 1 =
8/2 =
4/1 =
4
This is because of slope formula which is x-x/y-y
The angle is the cosine inverse function because base over hypotenuse. Then the angle will be 37°.
<h3>What is trigonometry?</h3>
The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
The triangle with base of 4 units and hypotenuse of 5 units.
We know that the angle is given by the cosine inverse function because base over hypotenuse. Then we have
⇒ cos⁻¹ (4/5)
Then the angle will be
⇒ 36.869 ≈ 37°
