Hello,
a-3b=4 (1)
a-b=-2 (2)
(1)-(2)==> -2b=6
=>b=-3 and a=-2+(-3)=-5
Answer D
Proof
-5+3=-2
-5-3(-3)=4
Answer: Option 4
Step-by-step explanation:
The way to tell if a function has an inverse is to see if it passes the horizontal line test (if a horizontal line crosses the graph more than once).

This is probably in the context of a discussion of significant figures and accuracy.
When we record a measurement of 4.15 cm with two significant figures, that means we believe the exact value is in the range from 4.145 cm to 41.155 cm
Similarly 7.34 really means between 7.335 and 7.345 cm.
The minimum area rectangle is
The maximum area rectangle is
Choice A
P(x) = (x^2)(x - 4)^2(x + 4) + some constant(b)
2025 = (1^2)(1 - 4)^2(1 + 4) + b
2025 = 45 + b
b = 1980
Complete Equation:
p(x) = (x^2)(x - 4)^2(x +4) + 1980
or expanded form
p(x) = x^5 - 4x^4 - 16x^3 + 64x^2 + 1980
