The degree of polynomial 5x-7 is
jolli1 [7]
Hello!

The degree would be one because the x in this particular equation doesn’t have an exponent, so you assume that the exponent is one because 5x to the first power is equal to 5x.

I hope this helps!

Jade has $451.89 in her checking account. After 3 checks, each for the same amount, are deducted from her account, she has $358.
steposvetlana [31]

Answer:

3rd, 4th, and 5th options.

Step-by-step explanation:

The way this was formatted was a little weird, but the 3rd, 4th, and 5th options are correct I think.

If there was 358.92 left, it has to be divided 3 ways (after subtracting 451.89 - 358.92). So that means that 3c or c+c+c could be correct, as well as using dis. property to switch around the last one I guess.

if this helped, brainliest is appreciated.

Find the federal income tax of a married couple with two children, who have a combined income of $100,000.
Galina-37 [17]

Answer:

 $9,937.50

Step-by-step explanation:

Given

Total income of a married couple = $100,000

Number of children the couple has = 2

The taxable income of the family can be calculated by

Taxable income = total income - exemption deduction - standard deduction

We know that the exemption deduction for a married couple with two children as fixed by the U.S. government is $15,600.

And the standard deduction for a married couple with two children as fixed by the U.S. government is $12,200.

Thus the taxable income can be calculated by

Taxable income = total income - exemption deduction - standard deduction

                           = $100,000 - $15,600 -  $12,200

                           = $72,200.

So the taxable income is $72,200.

Now if the taxable income is in the range between

$17,850 to $72,500, the tax is $1,785 plus the marginal rate of 15% of the amount of $72,200 that is over $17,850.

Now in order to calculate tax ---

add $1,785 plus the marginal rate of 15% of the amount of $72,200 that is over $17,850.

Now deducting $17,850 from $72,200 will give $54,350.

So 15% of $54,350 is $8152.50

Therefore add $1,785 and $8,152.50 = $9,937.50

Therefore the tax payed by the couple is $9,937.50
