Answer:
x = 7
Step-by-step explanation:
b = 19
substitute x = - into the equation and solve for b
5(- )² - b + 12 = 0
+ = b
= b
multiply both sides by 5 and divide by 4
b = = 19
2 13/15. take 4 1/5-1 1/3 and convert to have common denominator. then it is 4 3/15- 1 5/15 which is 2 13/15
Answer:
false bc the y intercept is in a different place which in return would alter the entire equation
n/7 - 8 < -11
add 8 to each side
n/7 < -3
multiply by 7
n< -21
False
The only time we flip the inequality symbol is when we multiply or divide by a negative.
