Answer:
-7/4
Step-by-step explanation:
change in y over (/) change in x
or
f(b) - f(a) over (/) b - a
= 2-(-5) / -3-1
= 2+5 / -3-1
= 7 / -4
Number of red cards including 2 red queens = 26
Number of black queens = 2
Therefore, number of red cards including 2 red queens and 2 black queens = 26 + 2 = 28
Number of cards neither a red card nor a queen = 52 - 28 = 24
Answer:
Relationship is :linear
Rate of change : 3
Y-intercept : (0,1)
Equation that models the data : y=3x+1
Step-by-step explanation:
Answer:
The
number 2
Step-by-step explanation:
What we need here is just the sign of the discriminant
From the question in this case, the discriminant is positive
Thus, whenever we have a positive discriminant, then the number of real solution is 2 and these two are distinct (different from one another).
Hi there.
Glad to see you using Brainly!
Equation:
a^2-b^2c^2
Then, multiply the terms with equal exponents.
(We can do this by multiplying their bases)
After:
a^2 - (b c)^2
Now, using a^2 - b^2 = (a-b)(a+b) we factor.
Therefore, after using that we get:
(a-bc) x (a+bc)
Therefore, our solution is
(a - bc) x (a+bc)
Thanks for using Brainly!
