13, -7, -1, 0, <, >, 66, -12
Answer:
(6,12)
Step-by-step explanation:
Substitute the value of y into y=2x:
x+6=2x
x=6
Substitute x into the equation of y=2x
y = 2*6 = 12
(6,12)
Answer:
38
Step-by-step explanation:
Given that,
x = -4
f(x)=x² - 4x +6
so,
f(-4)= (-4)² - 4 . (-4) +6
=16 +16 +6
= 38
Answer:
y=1-2x
x=2
(x,y)=(2,-3)
Step-by-step explanation:
Answer:
D) 
Step-by-step explanation:
Basically, if you plug in the x and y-coordinates into an equation, both sides should work out to be equal to each other:
Since 
, we can eliminate choice A
Since 
, we can eliminate choice B
Since 
, we can eliminate choice C
Therefore, since 
, then D is correct. Also,
