Answer:
Step-by-step explanation:
This is awfully hard to read. Use returns to separate paragraphs.
ax = bx + 1 Subtract bx from both sides.
ax - bx = 1 take out x as a common factor
x(a - b) = 1 Divide both sides by a - b
x = 1 / (a - b)
I think the second one is the one you want.
x is the same as the reciprocal of the difference between a and b.
Answer:
11
Step-by-step explanation:
Let's call the white marbles w and the red marbles r. We can write:
w + r = 16 (1)
w = 3r - 4 (2)
3r - 4 + r = 16 (3) (Substitute (2) into (1))
4r = 20 (simplify)
r = 5 (divide by 4) which means w = 16 - 5 = 11
Answer:
Isaac has $4.80 left
Step-by-step explanation:
$1.20 + 2.00 = 3.20
$8.00 - 3.20 = 4.80
It is true that the graph represents a function
<h3>How to determine if the graph represent a function?</h3>
For a graph to represent a function, the following must be true
Each x value on the graph must point to exactly one
The above means that the function must pass the vertical line test
The given graph would pass the vertical line test
This is so because:
Each x value on the graph points to exactly one
Hence, the graph represents a function
