Answer:
y = 5
Step-by-step explanation:
The answer would be (-6,5)
Answer:
One solution: x=6, y=7. (6, 7).
Step-by-step explanation:
y=x+1
y=2x-5
-----------
x+1=2x-5
1=2x-x-5
x-5=1
x=1+5
x=6
y=6+1=7
Add all the numbers that are the same, for example add the x’s and then leave the 35 next to it.. for example: 4x - 35!!
Answer:
Factor this polynomial:
F(x)=x^3-x^2-4x+4
Try to find the rational roots. If p/q is a root (p and q having no factors in common), then p must divide 4 and q must divide 1 (the coefficient of x^3).
The rational roots can thuis be +/1, +/2 and +/4. If you insert these values you find that the roots are at
x = 1, x = 2 and x = -2. This means that
x^3-x^2-4x+4 = A(x - 1)(x - 2)(x + 2)
A = 1, as you can see from equation the coefficient of x^3 on both sides.
Typo:
The rational roots can be
+/-1, +/-2 and +/-4
