Answer:
x = 4
Step-by-step explanation:
subtract 2 from both sides. then -4x is equal to -16. divide by -4 which gives you 4. Hope this helped!
First one and the last one are rational. And the other two of them are irrational.
Answer:
A, B, C, E
Step-by-step explanation:
It can be seen from the figure that the points A, B, C and D, all are lying in the line t.
=> So that it can be concluded that AC and BC and BD have the slopes which are equal to each other and also equal to the slop of line t
So that all answer A, B, C are true.
In addition, as FD is parallel with x - axis, so that slope of the line t is equal to <em>tan angel FDB </em>
As FDB is the right triangle with BFD = 90°
=> tan angel FDB = FB/ FD (tan of an acute angel in the right triangle = opposite side/ adjacent side)
=> Slope of the line t is equal to FB/ FD
=> Answer E is true
Answer:
(a)
Step-by-step explanation:
using the rule of exponents
• 
⇔ 
, hence
= 
= 
→ (a)
