Answer:
No solution
Step-by-step explanation:
Assume x - 4 ≠ 0 and x + 5 ≠ 0,
note (x - 4)(x + 5) = x² + x - 20, so x² + x - 20 ≠ 0
Multiply by (x - 4)(x + 5) both sides and
get
x(x + 5) - 4(x - 4) = 36
x² + 5x - 4x + 16 = 36
x² + x - 20 = 0
But we have assumed x² + x - 20 ≠ 0
So the equation has no solution
Answer:
For example, 6(1001) + 3(110) = 6006 + 330 = 6336 is a palindrome. Since 11 is a factor of both 1001 and 110, we conclude that all four digit palindromes are divisible by 11.
Answer:
x= -11
Step-by-step explanation:
the coefficient is variable that appears before a number . bearing this in mind, the coefficient of x is therefore 2 .
the value of x is:
>32+2x=10
>2x=10-32
>2x= -22
>x= -11
Answer
D
Why?
Because one of the x value is used twice
Answer:
-19/36
Step-by-step explanation:
We can find the slope using
m = ( y2-y1)/(x2-x1)
m = ( 94-56)/( 28 -100)
= 38 / -72
= -19/36
