Question

Consider this system of equations. Which shows the second equation written in slope-intercept form?

[tex]y = 3x - 2.[/tex]

[tex]10(x + \frac{3}{5} ) = 2y[/tex]

A. [tex]y = 5x + \frac{3}{10}[/tex]

B. [tex]y = 5x + 3[/tex]

C. [tex]y = \frac{1}{5} x + \frac{3}{25}[/tex]

D. [tex]y = \frac{1}{2} x + 6[/tex]

Answer:

B. [tex]y = 5x + 3[/tex]

Step-by-step explanation:

Given

Equation 1: [tex]y = 3x - 2.[/tex]

Equation 2: [tex]10(x + \frac{3}{5} ) = 2y[/tex]

Required:

Equivalent of equation 2

To get an equivalent of equation 2 (in slope intercept form), first we have to simplify equation 2

[tex]10(x + \frac{3}{5} ) = 2y[/tex]

Open the bracket

[tex]10*x + 10 *\frac{3}{5} = 2y[/tex]

[tex]10x + \frac{30}{5} = 2y[/tex]

Simplify fraction

[tex]10x + 6 = 2y[/tex]

Divide through by 2

[tex]\frac{10x}{2} + \frac{6}{2} = \frac{2y}{2}[/tex]

[tex]5x + 3 = y[/tex]

Re-arrange

[tex]y = 5x + 3[/tex]

The next step is to compare each of option A through D with [tex]y = 5x + 3[/tex]

A.

[tex]y = 5x + \frac{3}{10}[/tex] is not equal to [tex]y = 5x + 3[/tex]

We check the next available option

B.

[tex]y = 5x + 3[/tex] is equal to [tex]y = 5x + 3[/tex]

This option is equivalent to the second equation in slope-intercept form.

We check further if there are more equivalent options

C.

[tex]y = \frac{1}{5} x + \frac{3}{25}[/tex]

Convert fraction to decimal

[tex]y = 0.2x + 0.12[/tex]

This is not equal to [tex]y = 5x + 3[/tex]

D.

[tex]y = \frac{1}{2} x + 6[/tex]

Convert fraction to decimal

[tex]y = 0.5x + 6[/tex]

This is not equal to [tex]y = 5x + 3[/tex]

Hence, the only equation that is equivalent to the second equation written in slope intercept form is Option B

Answer:

The answer is B

Can i have Brainliest

The price of the 4rth item is $0.50.

The three prices add to 1.50 + 3.00 + 4.00 = $8.50.

The three prices multiply to 1.50 x 3.00 x 4.00 = $18.00.

You might see that adding another $0.50 will take the total to $9.00, and multiplying by another $0.50 will take the product to $9.00 also, but the answer can also be found using algebra. Let's call the unknown price P:

1.50 + 3.00 + 4.00 + P = 1.50 x 3.00 x 4.00 x P

8.50 + P = 18.00 x P

8.50 = 18.00 x P - P

8.50 = 17.00 x P

8.50/17.00 = P

P = 0.50.

Final answer:

To solve the puzzle, we create an equation with the fourth price as 'x' and set the sum of the prices equal to the product of the prices. After simplifying, we find that the fourth item must cost $2.00 to satisfy the condition.

Explanation:

The student is faced with a mathematical puzzle involving the addition and multiplication of prices of items purchased. The condition is that the prices added together equals the product of the prices. Given three of the prices as $1.50, $3.00, and $4.00, let us assume the price of the fourth item is x. Therefore:

The equation to solve is:

$1.50 + $3.00 + $4.00 + x = $1.50 × $3.00 × $4.00 × x

Simplifying the equation:

$8.50 + x = $18.00 × x

Subtracting $8.50 from both sides gives us:

x = $18.00 × x - $8.50

Dividing both sides by x:

1 = $18.00 - $8.50 / x

Finally, solving for x:

x = $18.00 / ($18.00 - 1)

x = $2.00

Thus, the price of the fourth item is $2.00.

​

Step-by-step explanation:

Answer:

a.

Clear Prints = [tex]2p[/tex]

Sue = [tex]15 + 0.5p[/tex]

b.  10 posters

c.  See Below

d.  Clear Prints

e. See Below

Step-by-step explanation:

Complete Question:

Ms. Chang’s class decides to order posters that advertise a walkathon to raise money for a local charity. Ichiro obtains quotes from two different companies.Clear Prints charges $2 per poster. Posters by Sue charges $15 plus $.50 per poster.

a. For each company, write an equation Ichiro could use to calculate the cost for any number of posters.

b. For what number of posters is the cost the same for both companies? Explain.

c. Which company do you think the class should buy posters from? Explain your reasoning.

d. If Ms. Chang’s class has an $18 budget for posters, which company do you think the class should buy posters from?

e. If Ms. Chang donates an additional $10 for ordering posters, does it impact the decision made? What factors influenced your decision?

Solution:

a.

Let the number of posters be "p" so

Clear Print would take 2 * p or "2p"

Sue would take a fixed cost of $15 and 0.5p, so "15 + 0.5p"

b.

We want cost of both to be same. So we can equate:

[tex]2p=15 + 0.5p[/tex]

Now, using algebra, we can solve for "p", the number at which both of the printers will cost same. Lets do this:

[tex]2p=15 + 0.5p\\2p-0.5p=15\\1.5p=15\\p=10[/tex]

So, for 10 posters, the cost of both will be same

c.

It depends.

If the number of posters they order is LESS THAN 10, they should order from Clear Prints. If the number of posters they print is "10", then they can choose any one of the printers since cost would be same. If they print more than 10 posters, then they should choose to go with Sue, as it will cost less.

d.

If the budget is $18, they can get:

Clear Prints = 18/2 = 9 posters made

Sue = 15 already gone as fixed cost, so remaining is 18 - 15 = 3

At 0.5 per poster, 3/0.5 = 6 posters

So, taking Clear Prints would be better.

e.

The budget of 18 is increase by 10, so the budget is:

18 + 10 = $28

From clear prints, you can get:

28/2 = 14 posters

From Sue, you can get:

28 - 15(fixed cost) = 13 left for posters

13/0.5 = 26 posters

Definitely, Sue gives more, so decision made at $18 budget to get Clear Prints would be impacted because they should now go with Sue since it will give them better deal and more posters.

Simplify:

V = 4/3 * 3.14 * 125 = 523.3 cubic centimeters

The possible solutions are -3 and 7, and the extraneous solution is x = -3,

From the steps shown, the last step is:

[tex]0 = (x + 3)(x - 7)[/tex]

Rewrite as:

[tex](x + 3)(x - 7)=0[/tex]

Split

[tex](x + 3)=0\ or\ (x - 7)=0[/tex]

Remove brackets

[tex]x + 3=0\ or\ x - 7=0[/tex]

Solve for x

[tex]x =-3\ or\ x =7[/tex]

So, the possible solutions are -3 and 7

Substitute -3 and 7 for x in the original equation to determine the extraneous solution.

[tex]\sqrt{30 - 2x}= x - 3[/tex]

[tex]\sqrt{30 - 2(-3)}= -3 - 3[/tex]

[tex]\sqrt{36}= -6[/tex]

Take square root of 36

[tex]6= -6[/tex]

[tex]\sqrt{30 - 2x}= x - 3[/tex]

[tex]\sqrt{30 - 2(7)}= 7- 3[/tex]

[tex]\sqrt{16}= 4[/tex]

Take square root of 16

[tex]4= 4[/tex]

Hence, the extraneous solution is x = -3, because [tex]6 \ne -6[/tex]

Answer:

24 pi/3 or approximately 25.12 cubic feet

Step-by-step explanation:

A cone's volume is a third of a cylinder's volume.

To find Ben's age, we establish an equation based on the given information that Ben is three times as old as Daniel and four years older. Solving this equation reveals that Daniel is 2 years old, therefore, Ben is 6 years old.

The question states that Ben is 3 times as old as Daniel and also 4 years older than Daniel. To solve for Ben's age, let's assign the variable D to represent Daniel's age. Therefore, Ben's age can be expressed as 3D. It's also stated that Ben is 4 years older than Daniel, which gives us another equation, Ben's age equals Daniel's age plus 4 (D + 4).

Setting these two expressions for Ben's age equal to each other gives us: 3D = D + 4. By solving this equation, we subtract D from both sides to get 2D = 4. Dividing both sides by 2 gives us D = 2, which is Daniel’s age.

To find Ben's age, we multiply Daniel’s age by 3, as Ben is three times older than Daniel. So, Ben's age is 3 * 2 = 6 years old.

The equation that have no solution is:  6x + 1 = 3(2x - 4).

The correct option is the first option.

Here, we have to check which of the equations have no solution, we need to solve each equation and see if they lead to a contradiction or an inconsistency.

If the variable (x) cancels out during the solving process, it means that the equation has no solution.

1) 6x + 1 = 3(2x - 4)

Expand the right side: 6x + 1 = 6x - 12

Subtract 6x from both sides: 1 = -12

In this case, we end up with a contradiction (1 = -12), which means there is no solution.

2) 2 - 5x = 7x - 12

Add 5x to both sides: 2 = 12x - 12

Add 12 to both sides: 14 = 12x

Divide by 12: x = 14/12 = 7/6

This equation has a solution.

3) 4(3 - x) = 2(6 - 2x)

Expand both sides: 12 - 4x = 12 - 4x

Subtract 12 from both sides: -4x = -4x

In this case, the variable (x) cancels out, which means any value of x would satisfy the equation.

So, this equation has infinitely many solutions.

4) 5(x + 2) = 2(x - 4)

Expand both sides: 5x + 10 = 2x - 8

Subtract 2x from both sides: 3x + 10 = -8

Subtract 10 from both sides: 3x = -18

Divide by 3: x = -18/3 = -6

This equation has a solution.

5) -4(x + 3) = 4(x - 1)

Expand both sides: -4x - 12 = 4x - 4

Add 4x to both sides: -4x - 4x - 12 = 4

Combine like terms: -12 - 4 = 8x

Combine like terms on the left side: -16 = 8x

Divide both sides by 8 to isolate x: x = -2

This equation has a solution.

So, the equation that have no solution is:  6x + 1 = 3(2x - 4).

Hence, The correct option is the first option.

The area of the blank M is 326.56m²

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes

Given data

Diameter of flower bed d=22m

Radius of flower bed r= 11m

Width of side walk x =4m

To solve for the area of the blank we need to subtract the area of the side walk from the area of the flower bed

But we don't know the diameter of the side walk

Let the diameter of the side walk be D= diameter of flower bed +2(width of the side walk )

D= 22+2(4)

D=22+8

D=30m

Radius of side walk is R=30/2 =15m

Area of blank =area of side walk minus area of flower bed

Area of circle =πr²

Area of blank M = πR²-πr²

M= π(R²-r²)

M= 3.14(15²-11²

M=3.14(225-121)

M=3.14(104)

M= 326.56m²

The area of the blank M 326.56m²
