Answers

Answer 1

Answer: d=5+n
0.1(5+n)+0.05n=1.7
0.5+0.15n=1.7
0.15n=1.2
n=8
d=13

Write an equation of the line that passes through the points (3,6) and (4,10) using function notation. A.) f(x) = 4x - 6

B.) f(x) = x + 4

C.) y = x + 4

D.) y = 4x - 6

Answers

Given:
(3,6) and (4,10)

a) f(x) = 4x - 6
f(3) = 4(3) - 6 f(4) = 4(4) - 6
f(3) = 12 - 6 f(4) = 16 - 6
f(3) = 6 f(4) = 10

b) f(x) = x + 4
f(3) = 3 + 4 f(4) = 4 + 4
f(3) = 7 f(4) = 8

c) y = x + 4
y = 3 + 4 y = 4 + 4
y = 7 y = 8

d) y = 4x - 6
y = 4(3) - 6 y = 4(4) - 6
y = 12 - 6 y = 16 - 6
y = 6 y = 10

Among the choices, choice A and D have the same value. However, the problem says functions notation. Choice A. is the function notation. A.) f(x) = 4x - 6

What is the maximum value of P = 4x + 2y, given the constraints on x and y listed below?

Answers

P = 4x + 2y

additional info.
x+2y < 10
y < 2
x > 0
y > 0

y can only be 0, 1, and 2.

x + 2(0) < 10 = x < 10
x + 2(1) < 10 = x + 3 < 10 = x < 10 - 3 = x < 7
x + 2(2) < 10 = x + 4 < 10 = x < 10 - 4 = x < 6

x = 10 ; y = 0 : P = 4(10) + 2(0) = 40 + 0 = 40
x = 7 ; y = 1 : P = 4(7) + 2(1) = 28 + 2 = 30
x = 6 ; y = 2 : P = 4(6) + 2(2) = 24 + 4 = 28

The maximum value of P is 40. Where x is 10 and y is 0.

Answer:

The maximum value of P is 40. Where x is 10 and y is 0.
