The lines whose equation is x = a, are vertical lines that pass through the point (a, y) where y is any real number. Additionally, vertical lines have an indefinite slope.
You can see it in the graph of this equation:
Answer:
13n +9
Step-by-step explanation:
There is nothing to solve. We can simplify the expression by eliminating parentheses and combining like terms.
7n +6(n +4) -15 . . . . . . given
7n +6n +6(4) -15 . . . . use the distributive property
(7 +6)n +(24 -15) . . . .identify and group like terms
13n +9 . . . . . . . . . . combine like terms
Hint #2 is a or b so ya, and 3 is c
Answer:
$7,000 at 7%; $13,000 at 8%
Step-by-step explanation
x: the amount invested at 7%
y: the amount invested at 8%
x + y = 20,000
7%.x + 8%.y = 1,530
⇒ x =7,000
y = 13,000
Answer:
2x - 4
Step-by-step explanation:
Expand the brackets.
10x - 2(4x+5) + 6 = 10x - 8x - 10 + 6
Evaluate like terms.
10x - 8x - 10 + 6 = 2x - 4
