Answer:
An inequality is a mathematical statement that EXPLAINS the relative values of two expressions.
Answer:
y = -1/5x + 2
Step-by-step explanation:
y = mx + b
m (slope) = -1/5
b (y-intercept) = 2
y = -1/5x + 2
this is using the straight line depreciation formula. you take the initial amount and subtract the amount that it loses each year times x
We have points (-1,3),(0,1),(1,3) so we can set up a system of equations for the general form ax^2+bx+c...
a+b+c=3, 0a+0b+c=1, a-b+c=3 getting differences
a+b=2, -a+b=-2 getting the sum
2b=0, b=0, making a+b=2 become:
a+0=2, a=2, making a+b+c=3 become:
2+0+c=3, c=1 so
y=2x^2+1
