Answer:
y=3x-(-2,-13)
Step-by-step explanation:
Because 1 * 21 = 3 * 7 ( 21 = 21 ) , 1/3&7/21 form a proportion.
Ax^2 + bx + c = 0
x^2 + x + 2 = 0
a = 1
b = 1
c = 2
b^2 - 4ac
1^2 - 4(1)(2)
= 1 - 8
= -7
The value of the discriminant is -7.
Answer:
11 and 16
Step-by-step explanation:
A good way to solve these is to work backwards.
X= larger and Y= smaller
if X is 5 more than 2Y than subtract 5 from the total
38 - 5 = 33
divide by 3
33/3 = 11
11 = Y and double that is 22 so add the five back into X and you get 16
