Coordinates of P: (a,b)
coordinates of Q:(3a,b)
coordinates of R:(2a,0)
i jus got a 100% on the quiz
Rearrange so x is the subject:-
(im assuning the f unction f(x) = (x + 2) / 7):-
f(x) = (x + 2)/7
7f(x) = x + 2
x = 7f(x) - 2
replace f(x) by x and x by another function
f = 7x - 2
Its D
<h3>Answer:</h3>
A) x = 2
<h3>Explanation:</h3>
<em>Try the answers</em>
Of the offered choices, the only ones that go through the given point are ...
... x = 2
... y = -5
The latter is horizontal and parallel to y = 7, so is not the choice you want. The appropriate choice is ...
... A) x = 2
_____
<em>Figure out the answer</em>
The given line is horizontal, so the line you want is vertical—of the form ...
... x = constant
The constant must be chosen so the line will go through a point with x=2. It should be obvious that the constant must be 2.
... x = 2 is perpendicular to y = 7 and goes through (2, -5).
Answer:
This is called a <u><em>parallelogram</em></u>
<u><em>Now, Area:</em></u>
Area = base * Height
Area = 4 * 3
Area = 12 cm²
