Answer:
c
Step-by-step explanation:
Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
The answer is check it N=300
Answer:
The answer would be (3,-4) This is because if you replace the variables with the numbers and solve the equation it will come out 0=0
So, lets solve.
y+4=-5(x-3)
-4+4=-5(3-3)
0=-5x0
0=0
So therefore the correct answer will be (3,-4)
Hope this helped
X - c = -b
x - 15 = -67
-67 + 15 = -52
x = -52
-52 - 15 = -67
I hope this helped!!!
