Answer:
(2x +1 ) (x -5 )
Step-by-step explanation:
2x^2-9x-5
(2x ) (x )
The factors of 5 are 1 and 5
One will be positive and one is negative, but which one
We want to get to -9 in the middle
2* -5 = -10 +1 = -9
(2x +1 ) (x -5 )
Lna^b = blna
let y = lne^e
so y = lne^e = e lne
lne = 1
y = e which is a constant (Euler's number) ~= 2.718
For Euler's number estimating methods request in a comment.
Hey there!
We can see that the y-intercept is 6, or (0, 6), because when x is equal to 0, that is the y-intercept.
Hope it helps and have a great day! Let me know if you need more help!
answer:
15
step-by-step explanation:
9, 10, 15, 17, 15, 14, 37, 45, 42, 13
- mode means the number that appears the most
- in the set of numbers, 15 appears twice, which the others appears only once
So we have the following system of equations:
We need to solve it by substitution. This means that we have to take the expression for x given by the second equation and replace x with it in the first equation:
So y=-1. If we use this value in the second equation:
So we have x=2 and y=-1 which means that there's one solution. Then the correct answer is A and the solution is (2,-1).
