Answer:

Step-by-step explanation:
The expression (t•s)(x) means t(s(x)) or t of s of x. It means to substitute s(x) into the equation for t(x).

Step-by-step explanation:
it says f(-4).
so, x = -4.
into what function segment is this "falling" ?
well, into the x < 3 segment, right ? because -4 < 3.
so, we need to use
f(x) = x² - 5
f(-4) = (-4)² - 5 = 16 - 5 = 11
Answer:
a- 2/5 + 1/4=.65 mixture of red and blue paint
(2/5) / .65 X 1.625=1 gallon of red paint
(1/4) / .65 X 1.625=5/8 gllaons of blue paint, because
1 + 5/8=1 5/8 gallons of purple paint.
b-1/10 + 2/5 + 1/4=.75 mixture of white, red and blue paint
(1/10) / .75 X 3/8= 1/20 gallons of white paint
(2/5) / .75 X 3/8=1/5 gallons of red paint
(1/4) / .75 X 3/8=1/8 gallons of blue paint, because
1/20 + 1/5 + 1/8=3/8 gallons of lighter purple paint.
