Answer:
two real, unequal roots
Step-by-step explanation:
This is a quadratic equation. The quadratic formula can be used to determine how many and what kind of roots may exist:
Find the discriminant, which is defined as b^2 - 4ac, if ax^2 + bx + c = 0. In this case, a = 1, b = -2 and c = -8, so that the discriminant value is
(-2)^2 - 4(1)(-8), or 4 + 32 = 36.
Because the discriminant is real and positive, we know for certain that we have two real, unequal roots
I believe it is context clues. The reader typically looks for context clues to understand the reading.
Answer:
p = 
Step-by-step explanation:
To make a perfect square
add ( half the coefficient of the x- term )² to x² - x, that is
x² + 2(- 
)x + with p = , thus
x² - x = (x - )² + 
Answer:
Lucy has $60
Step-by-step explanation:
Mel had 80
Lucy had 40
Now Mel has 100
and Lucy has 60
60/100 = 3/5
4y=5x+4
Divid by 4 to make slop intercept form
Y=5/4y +1
Slop =5/4
