Answer:
y =-3000x +12000
Step-by-step explanation:
answer is
1) 12000 is the constant therefore when the number of hours is 0 the tickets are 12000
2) the number of tickets (y) are reducing by 3000 for each hour(x). thus the coefficient of variable x should be -3000 (negative because it is reducing)
Answer:
x = -1
x = 3
Step-by-step explanation:
Add 1 to both sides:
Factor the left side:
Square root both sides:
Therefore:
Given:
Composite figure
To find:
The shapes in the composite figure.
Solution:
The image splitted into three shapes.
- Draw a line from top vertex to bottom vertex.
- We get one triangle.
- Similarly, draw another line adjacent to the previous line.
- We get another triangle and rectangle.
Therefore a composite figure divided into a rectangle and two triangles.
Y=mx+b m- slope b- y-intercept(where the line crosses the y axis)
31=.5(15)+b plug in your values
31=7.5+b simplify
23.5=b subtract 7.5 from both sides and your given b
y=.5x+23.5 plug everything into slope intercept form (y=mx+b)
Answer:
y= -2/7x-7
Step-by-step explanation:
slope intercept form is just a fancy way of saying y=mx+b
x being your input, y your output, m your slope, and b your y intercept
you can use the slope to determine your equation will look something like: y=-2/7x+b. To find your y-intercept all you do is determine how much the point will increase or decrease so it is equal to (0, y). In this case it will increase by 14 on the x's (so x is equal to 0) and 14*-2/7. When you have determined your y-int and slope you can then plug them into the equation instead of the variables.
