Answer:
44
Step-by-step explanation:
f(x) = -7x + 5x^2 + 10
f(-2) = -7(-2) + 5(-2)^2 + 10
= 14 + 20 + 10
= 44

<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>Let's find 'a' using Pythagoras theorem.</u>
- => 4² = 2² + a²
- => 16 = 4 + a²
- => 12 = a²
- => a = √12
- => a = √2 x 2 x 3
- => a = 2√3
- => a = 2 x √3
- => a = 2 x 1.732
- => a = 3.464 = 3.5 (Estimated)

Answer:
2
Step-by-step explanation:
We can find the slope of the line using
m = (y2-y1)/(x2-x1)
= (-2-2)/(-3- -1)
= -4/(-3+1)
= -4/(-2)
