Answer: 12x-4, 14 counters, 8 more counters
Step-by-step explanation: There are 2x yellow, 4x+6 red, and 6x-10 blue counters. We need to add all of this up to get the total number of counters. We first add the x's : 2x+4x+6x = 12x. Then we add the numbers. 6+ (-10) is -4. So, our expression is 12x-4. Next, we need to find out how many blue counters are in the bag. We know that there are 44 total counters and we need to find x because all the counters have x in them. 12x-4 = 44. We first add 4 to both sides to get 12x= 48 and x = 4. blue has 6x-10 counters so, blue has 24-10 = 14 counters. Red has 16+6 = 22 counters. 22-14 = 8 more counters
We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.
Equation:
y = 2x + 125

Answer:
The correct answer is 30
Step-by-step explanation:
Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.
The line passes through the points 
and 
To find: The rise-over-run value for the relationship in the graph.
Thus, the rise-over-run value for the relationship represented in the graph is 30.
Answer:
y-intercept = (0, -2)
x-intercept = (2, 0)
Step-by-step explanation:
The y-intercept is the value of y when x = 0. Therefore, Given the linear equation, y = x - 2:
Let x = 0:
y = 0 - 2
y = -2.
Therefore, the y-intercept of the linear equation, y = x - 2 is (0, -2).
The x-intercept is the value of x when y = 0.
Therefore, let y = 0:
y = x - 2
0 = x - 2
Isolate x by adding 2 to both sides of the equation:
0 + 2 = x - 2 + 2
2 = x
Therefore, the x-intercept is (2, 0).
