The value of f(-3) for the function f(a) = -2a² - 5a + 4 is 1.
<h3>What are functions?</h3>
Function relates input and outputs. The outputs are called the ranges of dependent variables while the input are called domain or independent variables.
Therefore,
f(a) = -2a² - 5a + 4
Hence,
f(-3) = -2(-3)² - 5(-3) + 4
Therefore,
f(-3) = -18 + 15 + 4
f(-3) = -3 + 4
f(-3) = 1

Answer:
5(2x + 6) = -4(-5 -2x) + 3x
10x + 30 = 20 + 8x + 3x
10x + 30 = 20 + 11x
Applying the additive inverse property, we get,
10x + 30 - 10x - 20 = 20 + 11x - 10x - 20
10 = x
