Hello,
answer in the jointed picture
Discriminant, D = b² - 4ac
x² - 4x + 5 = 0 comparing to ax² + bx + c = 0
a = 1, b = -4, c = 5
D = b² - 4ac = (-4)² - 4*1*5 = 16 - 20 = -4
In taking the square root of the discriminant of -4, √-4 = 2i = Not Real. So:
Discriminant is -4, so the equation has no real roots.
The second option is correct.
Answer:
It is reasonable.
Step-by-step explanation:
If you add 468 (amount of animals already there) and add how ever many more coming (192) then you'll get 680. If you add 100 more that will only be 780 animals.
Answer:
(m) increased, (b) unchanged. g(x)
(m) decreased, (b) unchanged. m(x)
(m) unchanged, (b) increased. h(x)
(m) unchanged, (b) decreased. n(x)
f(x): m = -1/2 b = 2
g(x): m = 1/3 b = -3
h(x): m = 2 b = 0
Slope-intercept form is y = mx + b, where the variable m represents the slope of the line and the variable b represents the y-intercept. Because we are given these values, all we have to do is plug in the given values into the equation for their respective variables.
y = mx + b
y = -5x + 8
Therefore, your answer is y = -5x + 8.
Hope this helps!
