what does x = -6(4x+3) = 6(-4x-3)

Answer:

y = - [tex]\frac{1}{6}[/tex] x - [tex]\frac{8}{9}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Rearrange 3x + 18y = - 16 into this form

Subtract 3x from both sides

18y = - 3x - 16 ( divide all terms by 18 )

y = - [tex]\frac{3}{18}[/tex] x - [tex]\frac{16}{18}[/tex], that is

y = - [tex]\frac{1}{6}[/tex] x - [tex]\frac{8}{9}[/tex] ← in slope- intercept form

Answer:

2y-1

The expression to determine the total amount Joe spent on gasoline and oil is 2.85 * g + 3.15 * c. If Joe bought 8.4 gallons of gasoline and 6 cans of oil, he will have spent 42.84 dollars in total.

Part A: To determine the total amount Joe spent on gasoline and oil, we need to calculate the cost of gasoline and the cost of oil separately, and then add them together.

The expression to calculate the cost of gasoline is: 2.85 * g, where 'g' represents the number of gallons of gasoline Joe bought.

The expression to calculate the cost of oil is: 3.15 * c, where 'c' represents the number of cans of oil Joe bought.

Therefore, the expression to determine the total amount Joe spent is: 2.85 * g + 3.15 * c.

Part B: If Joe bought 8.4 gallons of gasoline and 6 cans of oil, we can substitute these values into the expression we derived in Part A.

The total amount Joe spent can be calculated as follows:

Total amount spent = 2.85 * 8.4 + 3.15 * 6

Simplifying the expression:

Total amount spent = 23.94 + 18.90

Total amount spent = 42.84 dollars

Answer:

Step-by-step explanation:

Let

The relationship between x and y can be represented through a linear equation.

y = a . x + b

where,

a is the slope

b is the y-intercept

The slope refers to the price per print, that is, a = $0.15/p.

Then,

y = $0.15/p . x + b

Even if x = 0, there is a fixed cost of $3.00 (y = $3.00). We can replace these values in the expression above.

$3.00 = $0.15/p . 0 + b

b = $3.00

The final equation is:

y = $0.15/p . x + $3.00

If MaryAnn has $35,

$35 = $0.15/p . x + $3.00

$32 = $0.15/p . x

x = 213 p

She can order 213 prints.

Answer:

MOP = DAB

Step-by-step explanation:

the sides have to be matched up as well. the side with only one dash (MO) has to correspond with the side with one dash from the other triangle (DA). Thus, the letters in the sequence (MOP) have to match up in the same order (DAB)

The correct congruency statement with regards to the congruence of the triangles is the fourth statement

The details of the steps by which the congruence statement can be found can be presented as follows;

The marks on the segment indicates;

PO is congruent to BA

MO is congruent to DA

PM is congruent to BD

Therefore, the triangle MOP is congruent to the triangle DAB

The order in which the markings on the triangles are located can also be used to find the correct congruence statement

The name of the triangle MOP indicates that the vertice of the triangle between the segment with three marklings, III, and the segment with one marking, I, is considered first, which is the vertice M and D on each triangle

The next mentioned vertice is the vertice between the segment with one marking and the segment with two markings, which is the vertice O and A on each triangle

The third considered vertice is the third vertice on both triangles, which corresponds to the vertice P and B on each triangle

The congruency statement is therefore ΔMOP ≅ ΔDAB

A car is worth $300

Step-by-step explanation:

A board game allows players to trade and sell game pieces of equal value

We need to find how much the car is worth

Assume that the car is worth $x and the house is worth $y

∵ Player 1 traded three cars plus $100 for a house

∴ 3 x + 100 = y

- Subtract 100 from both sides

∴ 3 x = y - 100

- Subtract y from both sides

∴ 3 x - y = - 100 ⇒ (1)

∵ Player 2 sold two houses and a car for $2300

∴ x + 2 y = 2300 ⇒ (2)

Now we have system of equation to solve it

Multiply equation (1) by 2 to eliminate y

∵ 6 x - 2 y = - 200 ⇒ (3)

- Add equations (2) and (3)

∴ 7 x = 2100

- Divide both sides by 7

∴ x = 300

Answer:

The sell price of the truck rental after applying the coupon of 20 % is       $ 120  .

Step-by-step explanation:

Given as :

The regular rented price for the truck = $ 150

The discount as off coupon = 20 %

Let The sell price for truck after discount = x

So , Discount % = [tex]\dfrac{\textrm market price - \textrm Selling price}{\textrm market price}[/tex]

Or, 20 % = [tex]\dfrac{\textrm 150 - \textrm x}{\textrm 150}[/tex]

Or, [tex]\dfrac{x}{150}[/tex] = 1 -  [tex]\dfrac{20}{100}[/tex]

Or,  [tex]\dfrac{x}{150}[/tex] = [tex]\dfrac{100 - 20}{100}[/tex]

or,  [tex]\dfrac{x}{150}[/tex] = [tex]\dfrac{80}{100}[/tex]

Answer:

k = 5 and (6,2).

Step-by-step explanation:

Since (1,-1) is a solution of the equation 3x - ky = 8, so the point (1,-1) will satisfy the equation above.

Hence, putting x = 1 and y = -1 in the equation will give left-hand side = right-hand side.

So, 3(1) - k(-1) = 8

⇒ 3 + k = 8

⇒ k = 5 (Answer)

Therefore, the equation of the straight line is 3x - 5y = 8 ....... (1)

Now, putting x = 6 , then from equation (1) we get y = 2

Therefore, (6,2) is also a point on the graph of equation (1). (Answer)

The value of the expression 5w - (w/x) when w=6 and x=2 is 27.

The original expression given with the variables w and x is: 5w - (w/x). The question asks us to evaluate this expression when w=6 and x=2. So, we simply substitute w with 6 and x with 2 into the expression:

5*6 - (6/2) = 30 - 3 = 27

Therefore, the value of the expression 5w - (w/x) when w=6 and x=2 is 27.

Answer:

f(x)=5-x

Step-by-step explanation:

The equation y + x = 5 in function notation is f(x) = 5 - x, done by isolating the dependent variable, y, and expressing it as a function of x.

The equation y + x = 5 can be rewritten in function notation by isolating the dependent variable, y, which is standard procedure in function notation. To isolate y, we need to subtract x from both sides of the equation. Thus, the equation y + x = 5 becomes y = 5 - x. In function notation, where y is typically written as f(x), this would become f(x) = 5 - x.

Final answer:

To find the cost of 33 inches of wire, we calculate the cost per inch from the given 17 inches costing 51 cents, which is 3 cents per inch, and then multiply by 33 inches to get a total cost of 99 cents.

Explanation:

The student is asking to determine the cost of 33 inches of wire based on the given rate of 17 inches costing 51 cents. To solve this, we can set up a proportion where we compare the given inches of wire to the given cost and then find the cost for the desired inches of wire.

Step-by-Step Calculation:

First, we determine the cost per inch of wire by dividing the total cost by the total length of wire: 51 cents ÷ 17 inches = 3 cents per inch.

Next, we multiply the cost per inch by the desired length of wire to find the total cost: 3 cents/inch × 33 inches = 99 cents.

Therefore, 33 inches of wire will cost 99 cents at the same rate.

Answer:

x = 4 ± [tex]\sqrt{19}[/tex]

Step-by-step explanation:

Given

x² - 8x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 3 + 16

(x - 4)² = 19 ( take the square root of both sides )

x - 4 = ± [tex]\sqrt{19}[/tex] ( add 4 to both sides )

x = 4 ± [tex]\sqrt{19}[/tex], that is

x = 4 - [tex]\sqrt{19}[/tex], 4 + [tex]\sqrt{19}[/tex]

Final answer:

The solution set for the quadratic equation x² - 8x = 3 is found by completing the square, resulting in (4 - √19, 4 + √19).

Explanation:

To solve the quadratic equation by completing the square, we start with x² – 8x = 3. First, we move the constant term to the other side of the equation:

x² – 8x + ____ = 3 + ____

Now we need to find a number to fill in the blanks that makes the left side a perfect square trinomial. To do this, take half of the coefficient of x, which is -8/2 = -4, and then square it, which gives us 16. Add 16 to both sides:

x² – 8x + 16 = 3 + 16

x² – 8x + 16 = 19

The left side is now a perfect square, (x – 4)² = 19. Taking the square root of both sides gives us:

x – 4 = ±√19

Add 4 to both sides to solve for x:

x = 4 ±√19

Therefore, the solution set for the equation x² – 8x = 3 is (4 – √19, 4 + √19).
