Answer:
QR = 1
Step-by-step explanation:
PR = PQ + QR
PR = x + 19
PQ = 9
So now put what you know in the equation above.
PR = 9 + 2x + 19
PR also equals x + 19
so
x + 19 = 9 + 2x + 19
x + 19 = 2x + 28
19 - 28 + x = 2x
-9 + x = 2x
-9 = 2x - x
-9 = x
===================
QR = 2x + 19
QR = 2*-9 + 19
QR = -18 + 19
This really is kind of a nasty question. You don't expect to get a minus number of x.
(-2,-5)
you simply move five units to the left, since you are not going up and down, they Y axis stays the same. The X axis is the one you count.
B: Subtraction property of equality
yes
4g-124= -104, g-12= -7
g=5
4g-124= ? g-12
4(5)-124 5-12
4(5)= 20 5-12= -7
20 - 124= -104
