How do I solve these?
1 answer:
Solve liek a normal equation, except when you divide or muliply by a negative, flipi the sign direction
10.
divide both sides by -3
flip sign
p-7≤-7
add 7 to both sides
p≤0
so put a circle at 0 and shade it in and shade to the left and draw an arrow there (see attachment)
12.
times both sides by 15
-9+a>15
add 9 to both sides
a>24
put an open circle at 24 and go to the right (see attachment)

Answer:
- 2 + 5x² - 2x + 4
Step-by-step explanation:
A polynomial in standard form has the leading term( first term) of the term with the largest exponent.
Other terms then follow in descending powers.
Given
5x² - 2 + 4 - 2x
The term with the largest exponent is - 2 ← becomes first term
Thus the polynomial can be expressed as
- 2 + 5x² - 2x + 4 ← in standard form
