On Wednesday, his balance is -$55 this means that Sam had a debt of $55.
A day after, his balance was less than -$55. This means that Sam had a debt of MORE than $55. Notice that after applying absolute value, what was less than a negative number becomes greater when their absolute values are taken.
Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>
Answer:
E=(4,-2) F=(8,-2) H=(2,-6) G=(6,-6)
Step-by-step explanation:
Answer:
Domain: 
Inverse: 
Step-by-step explanation:
Since this is a linear function, the domain and range is simply the set of real numbers.
The inverse is obtain by switching the places of x and y, then solving for y.
Here,
y = -x + 5
So switching x and y,
x = -y + 5
Solving for y again,
y = -x + 5
Thus,
1/5 is the answer. How to slove: You turn the mixed number into an improper fraction which would be 15/4 =, because 4(3)= 12 + 3 = 15 and the denominator stays the same so it would be 15/4. Next, multiply ( the but dont forget to "flip" the improper fraction so it's 4/15) 3/4(4/15)= 1/5
