Answer: -2
Step-by-step explanation: This equation is written in <em>y = mx + b </em>form.
The slope is the multiplier or the coefficient of
the x-term whcih in this case is -2/
Its 20. |-2|+4-(-2)×(7). This simplifies to 2+4+(2×7)
f(x) + g(x) = 3x³ + 8x - 24
that is 3x³ + 7x - 26 + x + 2 = 3x³ + 8x - 24
Answer:
x = 9
