Two numbers have a difference of 0.7 and a sum of 1. what are the numbers?
Fofino [41]
<span>In order to determine the value of the numbers, we can set up algebraic equations to solve. For this case, we need to set up two equations since we have two unknown numbers. We do as follows:
 let x = first number and y = second number
 From the problem statement, we set up equations.
 Equation 1 - the numbers have a difference of 0.7
 x - y = 0.7
 Equation 2 - the numbers have a sum of 1
 x + y = 1
 Solving for x and y via substitution method,
 x - y = 0.7
(1-y) - y = 0.7
1 - 2y = 0.7
-2y = 0.7 - 1 = -0.3
y = 0.15 or 3/20
 x - 0.15 = 0.7
x = 0.85 or 17/20
 Thus, the two numbers are 0.15 and 0.85.</span>

PLEASE HELP 20 POINTS<br> multiply and simplify. <br> -3x^2y^2*y^4x^3
Elena-2011 [213]
You group the like terms and multiply, and remember that when you multiply two like terms like x^4 times x^3 you ADD the exponents, so you would have x^7.
For this problem:
so for the x's: -3x^2(4x^3) = -12x^5;
now for the y's: y^2(y^4) = y^6;
so your final answer is -12x^5y^6
