48. (3) 3

50. (4) 25x - 75

Step-by-step explanation:

Question 46

Let red marbles be 2x + 3 and black marbles be x
2x + 3 + x = 42
3x = 39
x = 13
No. of red = 2(13) + 3 = 29 marbles
(3) 29

Question 47

Parallel to a line means the slope is the same
(1) y = -4x + 3

Question 48

For the expression to be undefined, the denominator has to be 0
x - 3 = 0
x = 3
(3) 3

Question 49

Slope = -4 - 1 / 4 + 6
Slope = -5/10
Slope = -1/2
(3) -1/2

Question 50

Total = 25x
Left 3 boxes at home = -3x = -3(25) = -75
(4) 25x - 75

A(t)=934(1/2)t/30 for 20 years and 100 years

vichka [17]

$\bf A(t)=934\left( \frac{1}{2} \right)^{\frac{t}{30}}\qquad \qquad \stackrel{t=20}{A(t)=934\left( \frac{1}{2} \right)^{\frac{20}{30}}\implies A(t)=934\left( \frac{1}{2} \right)^{\frac{2}{3}}}
\\\\\\
\stackrel{t=100}{A(t)=934\left( \frac{1}{2} \right)^{\frac{100}{30}}\implies A(t)=934\left( \frac{1}{2} \right)^{\frac{10}{3}}}$

nothing to it, t = year, and you can just plug that in your calculator.
