Answer:
y = (x - 5)(4x + 1)
Step-by-step explanation:
The given function y = 4x^2 -19x - 5
Here we have to find the AC method.
Identify the value of A, B and C
A = 4 , B = -19 and C = -5
AC = 4*-5 = -20
Now find the facotr -20 such that when we add those two factors, we have to get the value of B. That is B = -19
Factors are -20 and 1
1 * -20 = -20
1 + (-20) = -19
y = 4x^2 -19x - 5
This can be written using the factors
y = 4x^2 - 20x + 1x - 5
Now let's factor by group the first two terms, then second two terms.
y = 4x (x - 5) + 1(x - 5)
y = (x - 5)(4x + 1)
That's the answer.
Hope this will helpful.
Thank you.
Answer:
n = 13/3
n = 1/2
Step-by-step explanation:
2n + 5 = 5n - 8
2n - 5n = - 8 - 5
- 3n = - 13
- n = - 13/3
n = 13/3
12n - 6 = 0
12n = 0 + 6
12n = 6
n = 6/12
n = 1/2
An irrational number is a number that does not have a end to it
if you mean √8, root 8 does not have a end to it, so it is irrational
pi, or (π) also does not have an end to it
144 - √ does not work as an expression, so it is not an answer
which leaves 0.45, which is rational, because it is terminated already
hope this helps
m=24=+(-9,1,3
3
Step-by-step explanation:
Substitute n=3,\pm 1n=3,±1 into 3m-9n=243m−9n=24
Solve for mm in 3m-(-9,1,3)=243m−(−9,1,3)=24
Hello,
As said T is the point of intersection of f and g, this means that there are only one point and that k=+1.
So dom f=
