Step-by-step explanation:

For two lines to be parallel they must have the same slope that is,M1=M2

For two lines to be perpendicular the slope of one must be the negative reciprocal of the other

Let's first find the slope of all three lines.

For line 1

6x-6=10y

2/5x-2/5=y

slope=2/5

For like 2

slope=5/3

For line 3

y=5/3x+2/3

We can therefore say that:

line 1 and line2 are neither parallel nor perpendicular

line 1 and line 3:

neither parallel nor perpendicular

line 2and line 3:

parallel lines

Answer:

x = ± [tex]\sqrt{\frac{p}{m} }[/tex]

Step-by-step explanation:

Given

mx² = p ( divide both sides by m )

x² = [tex]\frac{p}{m}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{p}{m} }[/tex]

Answer:

$21

Step-by-step explanation:

starting money: 51

Answer:

Number of small candles = 12

Number of large candles = 16

Step-by-step explanation:

Total candles = 28

x + y = 28 ---------------(I)

Cost of 'x' small candles = 4 *x = 4x

Cost of 'y' large candles = 6 *y = 6y

Total amount = $144

4x + 6y = 144 -------------(II)

Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'

(I) * (-4)            -4x - 4y = -112

(II)                    4x  + 6y = 144              {Now, add}

                              2y = 32

                               y = 32/2

y = 16

Plug in y = 16 in equation (I)

x + 16 = 28

      x = 28 - 16

x = 12

Answer:

12

Step-by-step explanation:

Answer:

1.Add or Subtract the same value from both sides.

2.Clear out any fractions by Multiplying every term by the bottom parts.

3.Divide every term by the same nonzero value.

4.Combine Like Terms.

5.Factoring.

6.Expanding (the opposite of factoring) may also help.

7.Recognizing a pattern, such as the difference of squares.

Answer:

16

Step-by-step explanation:

Always do multiplication first:

6*4 = 24

(-2)(4) = -8

Note: A negative times a positive always equals a negative

After multipying, do addition:

24+ (-8) = 24-8 = 16

Answer:

11/20 is a simplified fraction for 55/100

Answer:

x = 4

Step-by-step explanation:

4(2x - 5) = 5x - 8

Distribute 4: 8x - 20 = 5x - 8

Add 20 to both sides: 8x = 5x + 12

Substract 5x from both sides: 3x = 12

Divide both sides by 3: x = 4

Answer:

Rotational symmetry, also known as radial symmetry in biology, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.

Answer:

A shape symmetry if it appears the same after a rotation

Answer:

Jordyn spent $17 at the fair.

Step-by-step explanation:

From the information given, you know that the amount spent at the fair would be equal to the entrance fee plus the result of multiplying the price for every ride for the number of rides, which could be express as:

Total amount=5+2x, where:

x is the number of rides

With this formula, you can find the amount that Jordyn spent at the fair if she paid for admission and to go on 6 rides by replacing x with 6:

Total amount=5+(2*6)

Total amount=5+12

Total amount=17

According to this, the answer is that Jordyn spent $17 at the fair.

Answer:

of wht?....................

Answer:

w=0

Step-by-step explanation:

We know a point (3,1) and the slope (-8/3), so we can use point-slope form, which is y-y1=m(x-x1)

For reference, y1 is the y in the point, m is the slope, and x1 is the x in the point

So we subsitute it

y-1=-8/3(x-3)

do distributive prop.

y-1=-8/3x+8

add 1 to both sides

y=-8/3x+9

This is the equation of the line.

Now to find w, which is the x value.

The point will pass through line, so we can susbtitute the point into the equation.

9=-8/3x+9

subtract 9 from both sides

0=-8/3x

multiply by -3/8 on both sides (the reciprocal of -8/3), we need to isolate x

0=x

x=w

therefore, w=0

Answer:

15% discount

Step-by-step explanation:

Given:- Prices for a day ticket entrance at Disneyland Paris resort are

adult=55

child=45

family(2 adults ,2 children)=170

To find:- The family discount in percentage

Solution:- According to the question, Prices for a day ticket entrance at Disneyland Paris resort are

adult=55

child=45

So the price for two adults is 2×55=110

and the price for two child is 45×2= 90

but for the family(2 adults ,2 children),the price is 170

So, though the number of members are same but here a family is getting (110+90-170)=30 rupees less than the actual price (200)

so the discount is 100×30/200 =15%

So the family will get 15% discount.
