Answer:
f(x) = -8
Step-by-step explanation:
f(x) = x² + 2x – 8
f(x) = (-2)² + 2(-2) – 8
f(x) = (-2)² + 2(-2) – 8
f(x) = 4 + (-4) – 8
f(x) = 4 – 4 – 8
f(x) = 0 – 8
f(x) = -8

A) A ratio system
B) The 4 lb peanuts and the 1 lb mixture because the 4lb added to the 1lb of mixture give the correct percentages.
<span>This property is called associativity. It shows that it doesn't matter whether you perform the sum on the first two numbers and then the third, or on the second two and then the first, because you will get the same answer either way. That is because addition is associative.</span>
Turn y - 4 = -2/3(x - 6) into a linear equation.
y - 4 = -2/3(x - 6)
y - 4 = -2/3x + 4
+4 +4
y = -2/3x + 8
The equation that is perpendicular to y = -2/3x + 8 is y = 3x + 4 as shown in the image below using a graph.
The answer is that you are measuring "resistance".
If the segment is DE-energized, which means the entire device is shut down, at that point the main thing you can quantify with the meter- probes on the two ends of the segment is its resistance. The ordinary meter measures volts, amps, and ohms. If you touch
the probes to the two ends of the part and the circuit is empowered, at that point you measure the voltage over the component. If the circuit is DE-energized, at that point you are measuring the component's resistance.
