y=4/5x-11
Answer:
The SI unit for length is the meter (abbreviated m); its definition has also changed over time to become more accurate and precise. The meter was first defined in 1791 as 1/10,000,000 of the distance from the equator to the North Pole.
Answer:
x=3, -1/7
Step-by-step explanation:
7x^2-20x-3=0
Factor.
(x-3)(7x+1)=0
x-3=0 ⇒ x=3
7x+1=0 ⇒7x=-1 ⇒x= -1/7
Answer:
B & C
Step-by-step explanation:
Since x is greater than 38, 40 and 120 matches the condition.
Hope u understand.
Please mark as the brainliest
It is asking for the tangent ratio at B.
In my answer; angle=theta
tan(theta)=opposite/adjacent
tan(theta)= 3/2
