Answer:
b. 7x + 2.8y
Step-by-step explanation:
distribute the negative sign:
= -2x + 8.1 + -1(-9x + 5.3y)
= -2x + 8.1 + -1(-9x) + -1(5.3y)
= -2x + 8.1 +9x + -5.3y
combine like terms:
= (-2x + 9x) + (8.1 + -5.3y)
= 7x + 2.8y
Answer:
Prime number
Step-by-step explanation:
That is the question?
I think i need to picture of the graph
From G to K the graph increases and then decreases
Answer:
y = 0
x = 8
Step-by-step explanation:
subtract second equation from first one
3x - 6y - (3x - y) = 24 - 24 the - sign in front of the parenthesis effects the inside expressions
3x - 6y - 3x + y = 24 - 24 add/subtract like terms
-5y = 0 and so y = 0
to find the value of x we can use this information
3x - y = 24 since y = 0
3x = 24 divide both sides by 3
x = 8
