Diagonals of a rect. are equal...
diagonals bisect each each other...
from these two properties we get ,
4x-12 = 1/2 (7x-18)
2 (4x-12)=7x-18
8x-24=7x-18
x=6
HOPE IT HELPS YOU '_'
Hey there i can help ya !
check the slope between the moving points
slope between (–6, –1) & (–3, 2) = 1 slope between (-3, 2) & (–1, 4) = 1 slope between (-1, 4) & (2, 7) = 1
the points are collinear and make an angle of 45 degrees with the x-axis
we can have an equation of a line passing through (-6,-1) and slope 1 as
(y + 1) = 1(x + 6) y = x + 5 is your linear model mostly
ANSWER
Q(5,-2),S(-3,4)
The given points have coordinates,
P(5,2) and R(-3,-4).
The mapping for a reflection across the x-axis is
This implies that,
and
The correct choice is A.
The linear approximation means that you assume the function is linear. So, just do :
f(5) + f'(5) (x-5)
This works out, in this specific case
3 + 4 (- 0.2)
Hope this helps
Answer:
A: -2
Step-by-step explanation:
You want some factor k such that k(5x) +(10x) = 0. That is, 5k+10 = 0. The solution to this is k=-2, corresponding to selection A.
