A bag of potatoes weighs 9.42 pounds on a weighing scale.

In order to find least significant digit we have these rules,

1. The leftmost non zero digit is the most significant digit.

2. If there is no decimal point, the rightmost non zero digit is the least significant digit.

3. If there is a decimal point, the rightmost digits is the least significant digit even if it is a zero.

4. All digits between the least and most are also significant digits.

In our case rule number 3 is to be applied.

Our number is 9.42, the rightmost digits that is 2 is the least significant digits.

Answer:

-3, -4, -4, 0, 16, 64, 192.

Step-by-step explanation:

I don't know for sure if this is correct, but when i did it theses are the answers i got. You do y=8*2^x. Meaning you substitute the x for the x values such as -3, -2, and -1.  

Also if you have one there's a setting you can go to on an actual calculator and type in this on a Y/X chart. I didn't use one this time because i don't have one, but thought you'd find that information useful.

I NEED HELP...finding the slope-intercept form equation
Simora [160]

Answer: y=-13/12x-7

Step-by-step explanation:

To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }. We use the two given points to find the slope.

m=\frac{32-6}{-36-(-12)} =\frac{26}{-24} =-\frac{13}{12}

Now that we have our slope, we can start filling out the slope-intercept form equation.

y=mx+b

y=-13/12x+b

Since we don't know the y-intercept, we can use one of the given points and solve for b.

6=(-13/12)(-12)+b                              [multiply (-13/12) and -12]

6=13+b                                              [subtract both sides by 13]

b=-7

With the y-intercept, we can complete our equation.

y=-13/12x-7

Can anyone help with this question pleasee
Vladimir [108]

Answer:

y = 1

Step-by-step explanation:

Given:

a^{3y - 5} = \frac{1}{a^2}

Apply the negative exponent rule

a^{3y - 5} = a^{-2}

The bases will cancel each other

3y - 5 = -2

3y - 5 + 5 = -2 + 5

3y = 3

\frac{3y}{3} = \frac{3}{3}

y = 1

Write the formula for calculating taxable income.
Harlamova29_29 [7]

Answer:

taxable income = adjusted income - (deductions + Allowances/Exemptions)

Step-by-step explanation:

Taxable income is the type of income on which a person has to pay tax to the government. Taxable Income is calculated by subtracting the deductions and exemptions from the adjustable income.

With deductions you can either have itemized deductions or standard deductions.

Standard deduction consist of deductions like if a couple is married then they will have the deductions and if there are dependents of a person then he will have a standard deduction.

Itemized deductions consist of mortgages values, medical expenses, charity works etc.

This will help us to find the value of our taxable income

What is the solution of the inequality [3x+6]-2<10?
Ber [7]

Answer:

x > -3_2/3

Step-by-step explanation:

(3x+6)-2 < 10

Distribute  

-6x-12 < 10

    +12   +12

    -6x < 22

-6x/-6 < 22/-6

When you divide by a negative number you flip the inequality

x > 22/-6

Simplify

x > -3_2/3
