Answer:
f(-3)
f(a) = -2a² - 5a + 4
Substitute a with its value, -3
f(-3) = -2(-3²) - 5(-3) + 4
f(-3) = -2(9) + 15 + 4
f(-3) = -18 + 19
f(-3) = 1
the value of f(-3) is 1.
In this problem the big angle will be equal to two times the smaller angle so the correct expression is:

Now we can rewrite the equation so:
Answer:
(6+2)/(-4+8)= 8/4= 2
y+2=2(x+8)
y+2=2x+16
y=2x+14
Step-by-step explanation:
Answer:
this is very hard, I do not understand such math, I don't know
Answer:
1100
