Answer:
Clare didn't change the inequality symbol in the last step to >
Step-by-step explanation:
Given inequality is:
Clare's error was in the last step where she multiplied the inequality by -4 to remove the minus sign with x. When an in equality is multiplied/Divided by a negative number then the sign of inequality is reversed. < is changed to > and > is changed to less than.
The answer must have been x > -5
The correct way to solve is:
Hence,
Clare didn't change the inequality symbol in the last step to >
The minimum value for |x+5| is 0, so the minimum for f(x) is 0-8=-8.
There is no maximum for |x+5|, so neither does f(x).
Therefore the range of f(x)=|x+5|-8 is [-8,+inf) in interval notation, or
from -8 to infinity in words.
Answer:
1-4y+y
1-3y
Step-by-step explanation:
Answer: 7 blocks west
Step-by-step explanation:
she goes 8 blocks south
13 blocks west
8 blocks north
and 6 blocks east.
the 8 blocks south and then north cancel each other out, so she is on the same street horizontally, but the 13 blocks west only get 6 blocks back east, so she ends up 7 blocks west of her starting point because 13 - 6 = 7
Answer:
y= 1/3x -6
Step-by-step explanation:
you just have to plug the given values into the slope intercept formula:
y = mx +b
where M is the slope and B is the y-intercept
