the pay stub at right shows darla's earnings and taxes this week darla says her pay after taxes will be an amount greater than 6
1 answer:
She could round all the numbers to the tens and then subtract the sum of the taxes from the total earnings. She is incorrect.
<h3>How to approximate numbers for estimation?</h3>From the table showing Darle's earnings and taxes, we see that;
Total Earnings = $750
Federal Income Tax = $119.45
State Income Tax = $30.15
Other Taxes = $11.21
Now, looking at the taxes and looking at the total earnings, the best way to start approximating the total taxes to be deducted is to round them each to the nearest tens since the total earnings is also in the nearest tens. Thus, the taxes to the nearest tens are;
Federal Income Tax = $120
State Income Tax = $30
Other Taxes = $11
Thus;
Total tax to nearest tens = 120 + 30 + 11 = $161
Thus, amount left after tax = 750 - 161 = $589
Therefore we can conclude that She could round all the numbers to the tens and then subtract the sum of the taxes from the total earnings. She is incorrect because her statement that after taxes there will be an amount greater than 600 dollars does not tally with the above calculations.

Area of the square can be find:
Answer:
The solutions are:
(-15 , -4) ⇒ 1st
(3 , 2) ⇒ 3rd
(21 , 8) ⇒ 5th
Step-by-step explanation:
To find the solution of the graph let us make the equation of the line by using any two points on the line
The form of the linear equation is y = m x + b, where
- m is the slope of the line
- b is the y-intercept (value y at x = 0)
The formula of the slope is
From the figure
∵ The line passes through points (-3 , 0) and (0 , 1)
- Find the slope of the line
∴
- Substitute the value of m in the form of the equation
∴ y = x + b
∵ b is the value of y at x = 0
∵ y = 1 at x = 0 ⇒ y-intercept
∴ b = 1
∴ y = x + 1
Lets substitute the x-coordinate of each point to find the y-coordinate, if the y-coordinate is equal to the y-coordinate of the points, then the point is a solution
Point (-15 , -4)
∵ x = -15
∴ y = (-15) + 1
∴ y = -5 + 1 = -4 ⇒ same value of the point
∴ (-15 , -4) is a solution
Point (-6 , 1)
∵ x = -6
∴ y = (-6) + 1
∴ y = -2 + 1 = -1 ⇒ not the same value of the point
∴ (-6 , 1) is not a solution
Point (3 , 2)
∵ x = 3
∴ y = (3) + 1
∴ y = 1 + 1 = 2 ⇒ same value of the point
∴ (3 , 2) is a solution
Point (12 , 9)
∵ x = 12
∴ y = (12) + 1
∴ y = 4 + 1 = 5 ⇒ not the same value of the point
∴ (12 , 9) is not a solution
Point (21 , 8)
∵ x = 21
∴ y = (21) + 1
∴ y = 7 + 1 = 8 ⇒ same value of the point
∴ (21 , 8) is a solution
