Answer:
To find the inverse equation, switch the x and y variables then solve for y.
Original equation: .
y = 100 - x²
Inverse:
x = 100 - y²
y² = 100 - x
y = + √(100 - x) or the first option
Step-by-step explanation:
2a + c = 1850
2a + c (-c) = 1850 (-c)
2a = 1850 - c
2a/2 = (1850 - c)/2
a = 925 - (c/2)
hope this helps
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 >
