Answer:
What is the question or only
-12*F
Temperature in morning=-4*F
Temperature has dropped by=8*F
Temperature now=-4-8= -12*F
X-intercept: (8,0)
Y-intercept:(0,-12)
(x^2-5x-6)= (x+1)(x-6)
one of them has to be zero...
x=-1, x=6.
Hope this helps!
Answer:
44
Step-by-step explanation:
2x² - 2x - 5 = 0 is written in standard form ax^2 + bx + c = 0.
By looking at the formula, we can see that;
a = 2
b = -2
c = -5
Now, we can substitute these variables into the equation we are given and solve.
= b² - 4ac
= -2^2 - 4(2)(-5)
= 4 - 4(-10)
= 4 - (-40)
= 4 + 40
= 44
Best of Luck!
