X= 81/2 this is the answer
Answer:
function
Step-by-step explanation:
one input has one output, so it is a function
-2x+ 12 = x^2 +16
-2x -4 = x^2
-4= x^2 + 2x
-4= 3x
-4/3 = 3/3x
-1.333 (repeated) = x
Answer:
A.
Step-by-step explanation:
the second number is just 10 more than the first
The equation ofa line that passes throug (x1,y1) and has s slope of m is
y-y1=m(x-x1)
given
point is (-1,-3) and slope=4
y-(-3)=4(x-(-1)) or
y+3=4(x+1)
B is the answer
