Answer:
25.6
Step-by-step explanation:
To work this out you would first divide 65 by 10, which gives you 6.5. This is because by dividing it by 10 you are working out 10%. Then to work out 40% you would multiply 10% which is 6.5 by 4, which gives you 25.6.
1) Divide 65 by 10.
![65/10=6.5](https://tex.z-dn.net/?f=65%2F10%3D6.5)
2) Multiply 6.5 by 4.
![6.5*4=25.6](https://tex.z-dn.net/?f=6.5%2A4%3D25.6)
Answer:
x = 35
This equation is not a triangle!!!
The rate of change is -0.9.
Since the function f defined by f(x) = -0.9x + 665 is in slope-intercept form
f(x) = mx + b, we identify the coefficient on x to be the slope. And the slope is the rate of change.
For every one unit increase in x, y decreases by 0.9 units.
46.98 ... you move multiply 43.50 by .08 which is the tax percentage and that gives u how much tax it is
