Answer:
x = -1/3 and x = 4 choose 4
Step-by-step explanation:
3x2 + 11x – 4= 0
...
3xx - 12x + x - 4 = 0
3x(x -4) + x - 4 = 0
(x-4)(3x + 1) = 0
The amount paid in tax based on the information is Rs 13500.
<h3>How to compute the tax?</h3>
From the information given, the monthly salary is 45000. Therefore, the yearly salary will be:
= 45000 × 12
= 540000
Also, it's stated that the tax rate for first 450000 is 1% and next 100000 is 10%. Therefore, the amount that will be paid in tax will be:
= (450000 × 1%) + (90000 × 10%)
= 4500 + 9000
= 13500
Therefore, the amount paid in tax will be Rs 13500.

Answer:
y=-3x+7
Step-by-step explanation:
y=mx+b is the formula you are going to end up once completed.
This, by given two points:
(4,-5) (3,-2)
= Point-Slope Intercept Form
= After subtracting both from above
-3 = is your slope, decreasing.
Substitute -3 for y=mx+b
y=-3x+b
Use one of the given points (any) to find what b equals.
(4,-5)
x y
-5=-3(4)+b
-5= -12+b
7=b
Final Equation:
y=-3x+7
Answer:
51.96 (real answer) but then 52 ft is the rounded up answer
Step-by-step explanation:
1) Subtract 30 from 90 because that is the fallen or chopped off part of the pole.
2) Use Pythagorean theorem.
3) 30 squared + x squared = 60 squared
4) 900 + x squared = 3600
5) subtract 900 from 3600 = 2700
6) Get the square root of 2700 which is 51.96....
7) Round up to 52 feet because your teacher wanted you to round to the nearest foot.
