Answer:

See Explanation

Step-by-step explanation:

The options are not given; however, the solution is as follows;

[tex]3y = 27x[/tex]

Required

Determine relationships with the same constant of proportionality (k)

[tex]3y = 27x[/tex]

Divide both sides by 3

[tex]\frac{3y}{3} = \frac{27x}{3}[/tex]

[tex]y = \frac{27x}{3}[/tex]

[tex]y = 9x[/tex]

The relationship between y, x and k is:

[tex]y = kx[/tex]

Comparing [tex]y = kx[/tex] with [tex]y = 9x[/tex]; then

[tex]k = 9[/tex]

Hence, any of the options with k=9 answers the question.

Take for instance:

[tex]2y = 18x[/tex]

Dividing both sides by 2 gives

[tex]y = 9x[/tex] and hence; [tex]k = 9[/tex]

mutiply and open bracket minus each other

Answer:

So we know the shop spent $250 on equipment and they also purchased 300 T-shirts  for $2 each.

Knowing this, we only have to add to the $250, what they have paid for the  T-shirts.

So if each T-shirt is purchased by $2 and they have bought 300, we multiply:

2 * 300 = $600

So we add the $600 spent on T-shirts to the $250:

600 + 250 = $850

We could also have done it with by replacing T for 300 in C = 2T + 250:

C = 2*300 + 250 --> C = 600 + 250 --> C = $850

Answer:

you would need to find the area of the quantity of sheet metal needed for a roof

Step-by-step explanation:

The area is used to find the quantity of sheet metal needed for a roof.

We need to check whether the perimeter or area would be used to find the quantity of sheet metal needed for a roof.

Area: Area is defined as the amount of space that is occupied by any shape, object, or flat surface. The total number of square units that can fit into a shape or object or a flat surface defines the actual area.

Perimeter: The word 'perimeter' is derived from the Greek word 'Perimetron'. 'Peri' means 'around' and 'Metron' means 'measure'. The perimeter of a shape is calculated by adding up the length of all the sides or by measuring the outer boundary of a shape or an object.

Therefore, the area is used to find the quantity of sheet metal needed for a roof.

Answer:

y = -1/5x + 2.6

Step-by-step explanation:

Put the equation into slope intercept form:

5x - y = 12

-y = -5x + 12

y = 5x - 12

The slope of a perpendicular line will be the opposite reciprocal.

So, the slope of the new line will be -1/5

Then, plug this slope and the given point into the equation y = mx + b to find b

y = mx + b

3 = -1/5(-2) + b

3 = 0.4 + b

2.6 = b

So, the equation will be y = -1/5x + 2.6

Answer:

  x + 5y = 13

Step-by-step explanation:

When the equation of the line is given in the form ...

  ax -by = c

The perpendicular line can be written in the form ...

  bx +ay = constant

where "constant" is found by using the given point values for x and y.

Here, your equation will be ...

  x +5y = (-2) +5(3) = 13 . . . . for point (-2, 3)

The perpendicular line through (-2, 3) is x +5y = 13.

Answer:

Yes

Step-by-step explanation:

You can find the answer to this question by finding the value of x in both equations.

Let's start off with the first equation: [tex]x+4=5[/tex]

To find the value of x, you're going to have to subtract 4 from both sides. This is because you're looking for the value of only x, not x + 4. To leave x alone, you'd have to subtract 4, leaving that side with just x.

[tex]x+4-4=5-4[/tex]

[tex]x=1[/tex]

The answer to the first equation is x = 1.

Now let's start on the second equation: [tex]2x+8=10[/tex]

Like before, you're looking for x alone and in this equation, 8 is being added to 2x. Although x itself isn't alone, you'll first start off with 2x since you can simplify it thrughout the process. In this equation, you're going to subtract 8 from both sides to leave the variable x alone.

[tex]2x+8-8=10-8[/tex]

[tex]2x=2[/tex]

Now you're left with 2x = 2. Since you're looking for the value of x alone, you're going to divide both sides by 2. Because x is being multiplied by 2(2 times x = 2x) you're going to divide(opposite of multiply), which will cancel out the 2(in 2x).

[tex]\frac{2x}{2} = \frac{2}{2}[/tex]

[tex]x = 1[/tex]

The answer to the second equation is x = 1.

Since both equations have the same solution, the answer to your question would be yes.

Hello There!

Yes

If you want to know if your two equations are equivalent, let's try finding the answer to both of them.

[tex]x+4=5[/tex]

Let's find x.

We all know addition and subtraction. So let's just do

[tex]5-4=x[/tex]

So 5-4 is equal to 1.

So the answer for this equation is

[tex]x=1[/tex]

Let's move on to your second equation.

[tex]2x+8=10[/tex]

Now we must subtract 8 from both sides.

[tex]2x+8-8=10-8[/tex]

And this equals

[tex]2x=2[/tex]

Let's divide the both sides by 2.

[tex]\frac{2x}{2}=\frac{2}{2}[/tex]

The fraction [tex]\frac{2}{2}[/tex] is gonna equal one.

So [tex]x=1[/tex]

Now you have your answer for the second equation. Both answers were the same.

So the answer to your question is YES.

Answer: The length of [tex]\overline{NP}[/tex] is 10 units.

Step-by-step explanation:

We are given that,

Point O is on line segment [tex]\overline{NP}[/tex] .

Then, [tex]\overline{NP}=\overline{NO}+\overline{OP}[/tex]   (i)

Since we have given that OP=8 units and NO=2 units .

Now we will substitute these values in (i), we will get

[tex]\overline{NP}=8\ units+2\ units\\\\\Rightarrow\ \overline{NP}=10\ units[/tex]

Hence, the length of [tex]\overline{NP}[/tex] is 10 units.

Answer:

[tex]\Large \boxed{\displaystyle y=\sqrt{\frac{z \cdot w}{x}}}[/tex]

Step-by-step explanation:

Cross multiplication.

[tex]x \cdot y^2 =z \cdot w[/tex]

Dividing both sides by [tex]x[/tex].

[tex]\displaystyle \frac{x \cdot y^2 }{x} =\frac{z \cdot w}{x}[/tex]

[tex]\displaystyle y^2 =\frac{z \cdot w}{x}[/tex]

Taking the square root of both sides.

[tex]\displaystyle \sqrt{y^2 } =\sqrt{\frac{z \cdot w}{x}}[/tex]

[tex]\displaystyle y=\sqrt{\frac{z \cdot w}{x}}[/tex]

Answer:

14

Step-by-step explanation:

5(2)² - 2 - 4 = 14

The required value of the given expression 5z²-z-4 is 14 when z = 2,

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers. Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.

The expression is given in the question below as:

5z²-z-4​

To determine the value of the expression 5z²-z-4 when z=2, we need to substitute 2 for every occurrence of z in the expression and then simplify the expression.

5z²-z-4 when z = 2 is :

= 5(2²)-2-4

= 5(4)-2-4

= 20-2-4

= 14

Therefore, the required value is 14.

Given :

All the natural numbers below 1000 that are multiples of 3 or 5 .

To Find :

The sum of all the multiples of 3 or 5 below 1000.

Solution :

Max multiple of 3 is 999 .

Max multiple of 5 id 995 .

So , number of multiple of 3 is :

[tex]999=a+(n-1)d\\\\999=3+3(n-1)\\\\n=333[/tex]

Similarly for 5 .

[tex]995=a+(n-1)d\\\\995=5+5(n-1)\\\\n=199[/tex]

Now , sum of all multiple of 3 is given by :

[tex]S_3=\dfrac{n}{2}(2a+(n-1)d)\\\\S_3=\dfrac{333\times (2\times 3+332\times 3)}{2}\\\\S_3=166833[/tex]

Also , sum of all multiple of 5 is :

[tex]S_5=\dfrac{n}{2}(2a+(n-1)d)\\\\S_5=\dfrac{199\times (2\times 5+198\times 5)}{2}\\\\S_5=99500[/tex]

Therefore , total sum :

[tex]T=S_3+S_5\\\\T=166833+99500\\\\T=266333[/tex]

Now , there are some common number which we add two times like :

15 , 30 , 60 ......

So , we should subtract the sum of all multiple of 15 from T .

Now , sum of all multiple of 15 is 33165 .

So ,

[tex]T=266333-33165\\\\T=233168[/tex]

Therefore , the  sum of all the multiples of 3 or 5 below 1000 is 233168 .

Step-by-step explanation:

Using the sum/ difference → product formula

cos x - cos y = - 2sin( [tex]\frac{x+y}{2}[/tex])sin ([tex]\frac{x-y}{2}[/tex] )

sin x - sin y = 2cos ([tex]\frac{x+y}{2}[/tex] )sin ([tex]\frac{x-y}{2}[/tex] )

Given

(cosA - cosB)² + (sinA - sinB )²

= [ - 2sin([tex]\frac{A+B}{2}[/tex])sin([tex]\frac{A-B}{2}[/tex] ) ]² + [ 2cos([tex]\frac{A+B}{2}[/tex] )sin([tex]\frac{A-B}{2}[/tex] ) ]²
