Answer:
Step-by-step explanation:
Therefore, X + Y = 30. Also, Their difference is 6. Therefore, X - Y = 6. Therefore, the two numbers are X = 18 and Y = 12.
Answer:
x ≥ 5y
y ≤ 25
x ≤ 200
Step-by-step explanation:
It is given that Trisha wants to use at least 5 times as many key chains as thumb drives.
x represents the number of key chains and y represents the number of thumb drives.
Therefore, x ≥ 5y.
Total number of thumb drives is 25.
Therefore, y ≤ 25.
Total number of key chains is 200.
Therefore, x ≤ 200.
Answer:
1:3
Step-by-step explanation:
4:12 simplified is 1:3. for every 1 dark blue there are 3 light blues.
Answer:
1). Yes
2). Yes
3). No
Step-by-step explanation:
1). y = 3
We can rewrite this equation in the slope-intercept form as,
y = 0.x + 3
Here, slope = 0
y-intercept = 3
Therefore, it's a linear relation.
YES.
2). 2x - 5y = 10
5y = 2x - 10
y = 
Therefor, it's a linear function.
YES
3). y = x(x + 3)
y =x² + 3x
Since, this equation is a quadratic equation,
It's not a linear function.
NO
Answer:
B
Step-by-step explanation:
The line going with the graph for 1 day meets in-between 1, and 2 dollars, so it is 1.50
