Let f(x) = 9x − 2 and g(x) = −x + 3. Find f(g(x)).

Answers

f(x) = 9x - 2
g(x) = -x + 3

f(g(x)) = 9(-x + 3) - 2
f(g(x)) = 9(-x) + 9(3) - 2
f(g(x)) = -9x + 27 - 2
f(g(x)) = -9x + 25
f(g(x))=9(-x+3)-2
So: f(g(x)=-9x+27-2=-9x+25

Solve the equation for y (Y-3)^2=4y-12

Answers

If you would like to solve the equation for y, you can do this using the following steps:

(y - 3)^2 = 4y - 12
y^2 - 6y + 9 - 4y + 12 = 0
y^2 - 10y + 21 = 0
(y - 7) * (y - 3) = 0
1. y = 7
2. y = 3

The correct result would be y = 7 or y = 3.

Janet invested $10,000, part at 2% and part at 12%. if the total interest at the end of the year is $600, how much did she invested at 2%

Answers

Janet invested $6000 at 2 %.

Let x = amount invested at 2 %. Then 10 000 - x = amount invested at 12 %

interest at 2 % + interest at 12 % = 600

0.02x + 0.12(10 000 – x) = 600

0.02x + 1200 – 0.12x = 600

0.10x = 600

x = 600/0.10 = 6000

What is 75%,1/6,3/8,and 0.625 from least to greatest

Answers

Convert each term in decimal form. This is avoid confusion and for uniformity and ease in comparing the value of each term.

75%   is   0.750
1/6     is   0.167
3/8     is   0.375
0.625 is   0.625

From least to greatest, the order is: 

0.167 , 0.375 , 0.625 , 0.750

To find the volume of a cube, the equation is V=s^3, where s is the side length of the figure.

The lengths of the cubes in this problem are 8 and 6

8^3=512
6^3=216

512:216 is the ratio of the larger cube to the smaller cube
Simplify the ratio

512:216=128:54=64:27
