Answer:
A polynomial that has a degree of 2 is called a Quadratic.
Step-by-step explanation:
Answer:
x = - 3, y = - 1
Step-by-step explanation:
y = 7x + 20 -----> equation 1
4x - y = - 11
4x - ( 7x + 20 ) = - 11
4x - 7x - 20 = - 11
- 3x = - 11 + 20
- 3x = 9
x = 9 / - 3
x = - 3
Substitute x = - 3 in equation 1,
y = 7 ( - 3 ) + 20
= - 21 + 20
y = - 1
Hence,
x = - 3
y = - 1

Answer:
13 1/3 cups
Step-by-step explanation:
We assume flour is proportional to cookies, so we have ...
cups/dozens = x/10 = 4/3
Multiplying by 10 gives ...
x = 40/3 = 13 1/3
13 1/3 cups of flour are needed for 10 dozen cookies.
