Here is the question: Alicia wrote numbers:2,9,15,21 what of the numbers is not a composite number?

Answer:

[tex]\large\boxed{\text{The slope}\ m=3}[/tex]

Step-by-step explanation:

The slope-intercept form of an equation of a line:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the equation of a line in the standard form:

[tex]12x-4y=3[/tex]

Convert to the slope-intercept form:

[tex]12x-4y=3[/tex]         subtract 12x from both sides

[tex]-4y=-12x+3[/tex]        divide both sides by (-4)

[tex]y=\dfrac{-12}{-4}x+\dfrac{3}{-4}\\\\y=3x-\dfrac{3}{4}[/tex]

Answer:  The required slope of the given line is 3.

Step-by-step explanation:  Given that Helaine graphed the following equation :

[tex]12x-4y=3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We are to find the slope of the line.

We know that

the slope-intercept form of a straight line is given by

[tex]y=mx+c,[/tex] where m is the slope of the line.

From equation (i), we have

[tex]12x-4y=3\\\\\Rightarrow 4y=12x-3\\\\\Rightarrow y=\dfrac{12x-3}{4}\\\\\\\Rightarrow y=3x-\dfrac{3}{4}.[/tex]

Comparing with the slope-intercept form, we get

slope, m = 3.

Thus, the required slope of the given line is 3.

Both Jenna and Juan are INCORRECT.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1 job / 2 hours + 1 job / 1.5 hours = 1 job / x  When they work together.

1/2 + 1/1.5 = 1/x                Basic Equation. Change to decimal form

0.5 + 0.6666 = 1/x          Add like terms on the left

1.1666666 = 1/x              Multiply by x on both sides.

1.1666667 x = 1               Divide by 1.16666667

x = 1 / 1.166667               Do the division.

x = 0.8571428              

x = 6/7 of an hour.

This kind of question will always produce an answer that is less than the smallest number.

So the answer must be smaller than 2 hours or 1.5 hours.

The correct statement about rhombuses and parallelograms is that rhombuses always have four equal sides while parallelograms sometimes do not. The other options are not true for rhombuses and parallelograms.

The correct statement about rhombuses and parallelograms is option A) Rhombuses ALWAYS have four equal sides; parallelograms sometimes do not. A rhombus, by definition, is a four-sided figure with all sides having equal length while a parallelogram is a four-sided figure with only opposite sides being equal.

Options B, C, and D are incorrect. Rhombuses do not always have four right angles; that is characteristic of a rectangle. Parallelograms always have opposite sides equal and parallel, so C and D are not true.

ANSWER

[tex]x + y = 6[/tex]

EXPLANATION

Given the x- intercept: (a,0)

and the y-intercept : (0,b)

The equation in standard form is given by:

[tex] \frac{x}{a} + \frac{y}{b} = 1[/tex]

The given x-intercept is N(6,0) and y-intercept is M(0,6).

This implies that:

a=6, and b=6.

We substitute into the formula to obtain:

[tex]\frac{x}{6} + \frac{y}{6} = 1[/tex]

Multiply through by 6 to get the standard form of the equation as:

[tex]x + y = 6[/tex]

Answer:

60%

Step-by-step explanation:

p/100 = 18/30

Multiply each side by 100

p/100 *100 = 18/30 *100

p = 60

18 is 60 percent of 30

The number 18 out of the number 30 is 60 percent.

We need to find what percent is 18 out of 30.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Here, 18/30

= 9/15

= 3/5

= 0.6

In percentage 0.6×100

= 60%

Therefore, the number 18 out of the number 30 is 60 percent.

I agree with the one above.

Answer:

see explanation

Step-by-step explanation:

given

2x² - 5x - 3 = 0 ← in standard form

To factor the quadratic

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 3 = - 6 and sum = - 5

The factors are - 6 and + 1

Use these factors to split the x- term

2x² - 6x + x - 3 = 0 ( factor the first/second and third/fourth terms )

2x(x - 3) + 1(x - 3) = 0 ← factor out (x - 3)

(x - 3)(2x + 1) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]

3x-2

-(-5x+7)

☝️this is your equation

distribute your subtraction sign to -5x+7 and you get

Answer:

[tex]\large\boxed{(3x-2)-(-5x+7)=8x-9}[/tex]

Step-by-step explanation:

[tex](3x-2)-(-5x+7)\\\\=3x-2-(-5x)-7\\\\=3x-2+5x-7\qquad\text{combine like terms}\\\\=(3x+5x)+(-2-7)\\\\=8x-9[/tex]

Answer:

Step-by-step explanation:

To calculate how much more Lynn owes in taxes, we need to subtract her deductions from her total income to find her taxable income, then apply the tax rate from the provided table (which is missing in this case) to determine her tax liability. Unfortunately, without the tax table, we cannot accurately compute her tax obligation or the additional amount owed beyond the $3,150 withheld.

The question involves calculating how much more in taxes Lynn will owe after her deductions. Lynn's total income before deductions is $38,900. After subtracting her total deductions of $11,450, her taxable income becomes $27,450. Without the tax table provided in the question, we cannot determine the exact tax rate applicable to Lynn's taxable income nor can we calculate the precise amount of taxes she owes or how much more she will have to pay on top of the $3,150 already withheld by her employer. Typically, to find out how much more Lynn owes, we would apply the appropriate tax rate to her taxable income and then subtract the amount already withheld.

Without specific tax rates and brackets from the tax table, we can only outline the steps to calculate Lynn's tax liability. This scenario underlines the importance of having complete information to accurately determine tax obligations.

The amount Lynn owe in taxes is determined as $399. (Option D).

How to calculate the amount Lynn owe in taxes?

The amount Lynn owe in taxes is calculated  by applying the following method as shown below.

Lynn income before tax = $38,900

the total deduction in Lynn income = $11,450

amount withheld for taxes = $3,150

Lynn total income after tax is calculated as;

total income after tax = $38,900  - $11,450

total income after tax = $27,450

From the tax table attached, the tax payable for a head of household earing an income between $27,450 and $27,500 is $3,549.

So if the employer withheld $3,150 for tax, the remaining amount to be paid for tax is;

remaining amount for be paid for tax is calculated as;

= total tax - amount withheld

= $3,549 - $3,150

= $399

Thus, the amount Lynn owe in taxes is $399.

The complete question is below:

Lynn is a single mother with two children. She qualifies to file as head of household. Her total income before deductions was $38,900 last year. Her total deductions were $11,450. Her employer withheld $3,150 from her pay for tax. Use the tax table below. How much more will Lynn owe in taxes?

A. $570

B. $563

C. $407

D. $399

Answer:

True

Step-by-step explanation:

2(4)+(3)=11

8+3=11

11=11

(3)=(4)-1

3=4-1

3=3

all you have to do is substitute 4 for you x-values, and substitute 3 for your y-values, and then solve the equations.

True. X= 4 and Y= 3.

2(4) + 3 = 11

Answer:

all reals, except at x=0

Step-by-step explanation:

because x is in the denominator, x cannot equal 0

For this case we have a function of the form [tex]y = f (x),[/tex]where:

[tex]f (x) = \sqrt {\frac {3} {x}}[/tex]

we must find the domain of the function.

The domain is given by all the values for which the function is defined.

Note that "x" is not defined for negative numbers or for zero. Then x can only take strict higher values to zero.

Domain: {x | x> 0}

Answer:

Domain: {x | x> 0}

Answer:

80.73 each month

Step-by-step explanation:

The original price of the computer is $598. It is offered for 25% off. This means you pay 75% of the original price or 0.75(598) = 448.5. The sales price is $448.50. You will pay 8% tax on this price. This means you'll pay 100% of the price plus 8% more. So this is 1.08(448.5) = 484.38.

In total you pay 484.38 over 6 months. This means each month you pay 484.38/6 = 80.73.

The ratio of the number of gallons of oil to the number of gallons of solvent is 2:3.

The ratio of the number of gallons of oil to the number of gallons of solvent can be determined by subtracting the number of gallons of oil from the total volume of the mixture and then dividing by the number of gallons of solvent. In this case, the total volume of the mixture is 45 gallons and the number of gallons of oil is 18. So, the number of gallons of solvent is 45 - 18 = 27. Therefore, the ratio of the number of gallons of oil to the number of gallons of solvent is 18:27, which can be simplified to 2:3.
