B. Low risk so you won’t lose to much money if the investment goes bad and you want to start slow and low return because slowly does not mean you are putting the money into an expected booming stock.

The answer is B; x=18 and y = -20
Proof:
Solve the following system:
{4 x + 3 y = 12 | (equation 1)
{7 x + 5 y = 26 | (equation 2)
Swap equation 1 with equation 2:
{7 x + 5 y = 26 | (equation 1)
{4 x + 3 y = 12 | (equation 2)
Subtract 4/7 × (equation 1) from equation 2:
{7 x + 5 y = 26 | (equation 1)
{0 x+y/7 = (-20)/7 | (equation 2)
Multiply equation 2 by 7:
{7 x + 5 y = 26 | (equation 1)
{0 x+y = -20 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{7 x+0 y = 126 | (equation 1)
{0 x+y = -20 | (equation 2)
Divide equation 1 by 7:
{x+0 y = 18 | (equation 1)
{0 x+y = -20 | (equation 2)
Collect results:
Answer: {x = 18, y = -20
Answer:
1.) The sum of 12 and x 12 + x or x + 12
2.) The product of 25 and p 25 × p or 25p
3.) 24 increased by twice a number z 24 + 2z or 2z + 24
4.) The quotient of a number x and 4 x ÷ 4 . or x/4
5.) 6 less than a number x x - 6
6.) One-half of n squared n² ÷ 2 or n²/2
Step-by-step explanation: In most cases, the first expression uses symbols that are commonly used in arithmetic or elementary math. As you advance into Algebra, the ÷ and × are rarely used in favor of / or fraction form like
and
for division. Parentheses replace × for multiplication, for example (25)(p)=25p to avoid confusion with <em>x, </em>commonly used as an unknown or variable.
