Answer:x=2
Step-by-step explanation:2x + 8x - 1 = 19
10x=20
x=2
So -x-3>-1
add x to both sides
-3>-1+x
add 1 to both sides
-2>x
so x is any number less than -2 but not including -2
By using variables. x is the quotient, so 1/4 times x is the dividend, which is 3. Find what is x and 12 is your answer.
Answer:
x=-8 or x=-1 (first option)
Step-by-step explanation:
now expand the bracket on the right
now make it a quadratic equation:
Answer:
Step-by-step explanation:
f(x) = x² + 2x + 5
f(x+3) = (x+3)² + 2(x+3) + 5
= (x²+6x+9) + (2x+6) + 5
= x² + 8x + 20
