Answer:
0.44
Step-by-step explanation:
-3x^2 + 2y^2 + 5xy - 2y +5x^2 - 3y^2
Combine like terms
-3x^2 + 5x^2 = 2x^2 2y^2 - 3y^2 = -1y^2
2x^2 - 1y^2 + 5xy - 2y
Now plug in the solutions Note: it is easier if you have all decimals or all fractions (-1/10=-.1
2(0.5)^2 - 1(-0.1)^2 + 5(0.5)(-0.1) - 2(-0.1)
Simplify:
0.5 - 0.01 - 0.25 + 0.2
0.5 + 0.2 - 0.01 - 0.25
0.7 - 0.26
0.44
Answer:

The expression for 7 less than the product of a number and 8, increased by a number multiplied by 2 is 8n-7 +2n
Given :
7 less than the product of a number and 8, increased by a number multiplied by 2
We need to write the given statement in an expression
Lets 'n' be the unknown number
the product of a number and 8
Product means multiplication
the product of a number and 8 mean n times 8 that is 8n
7 less than the product of a number and 8, subtract 7 from 8n
Expression becomes 8n-7
This is increased by a number multiplied by 2
number multiplied by 2 is 2n
So the final expression for the given statement is 8n-7 +2n
