Answer:
x = 0
Step-by-step explanation:
Substituting the given "point" into the equation gives the possibilities for x.
<h3>Substitution</h3>Using (x, y) = (x, 8), the inequality becomes ...
3x -4 < 8
Solving for x gives ...
3x < 12 . . . . . . . add 4
x < 4 . . . . . . . divide by 3
Any value of x less than 4 will make (x, 8) a solution to the inequality. For example, ...
x = 0 . . . . . . (0, 8) is a solution to the inequality
{ y ≥ 2x + 1; y > -2x - 3 } Unbound

Answer:
The correct answer is option 3.
Step-by-step explanation:
Given : ΔPQR, QM is altitude of the triangle
PM = 8
MR = 18
To find = QM
Solution :
PR = 8 + 18 = 26
Let, PQ = x , QR = y, QM = z
Applying Pythagoras Theorem in ΔPQR
..[1]
Applying Pythagoras Theorem in ΔPQM
..[2]
Applying Pythagoras Theorem in ΔQMR
..[3]
Putting values of and
from [2] and [3 in [1].
z = ±12
z = 12 = QM ( ignoring negative value)
The length of QM is 12.
