Answer:

They are neither perpendicular nor parallel.

Step-by-step explanation:

Find the gradient of 2x + 6y = 42 by rearranging it in the form y = mx + c:

6y = -2x + 42

y = -(1/3)x + 7

The gradient is the co-efficient of x

Therefore the gradient is -(1/3)

The gradient of y = 2x - 1 is 2.

If they were parallel they would have the same gradient.

If they were perpendicular then the gradient of one would be the negative reciprocal of the other, e.g: if one was 2, the other would be -(1/2).

Neither of these are true, so they are neither perpendicular nor parallel.

The lines 3x+6y=42 and y=2x-1 are perpendicular

Two lines are parallel if they have equal slope

Two lines are perpendicular if the product of their slopes equals -1

The given lines are:

3x+6y=42 and y=2x-1

Rewrite each of the equations in the form y = mx + c

For line 3x + 6y = 42:

[tex]6y = -3x + 42\\\\y=\frac{-3}{6} x+\frac{42}{6}\\\\y=-0.5x+7[/tex]

The slope, m₁  =  -0.5

For line y = 2x - 1

The slope, m₂ = 2

Since m₁  ≠ m₂, lines 3x+6y=42 and y=2x-1 are not parallel

m₁ m₂  =  -0.5(2)

m₁ m₂  = -1

Since the product of the slopes equals -1, the lines 3x+6y=42 and y=2x-1 are perpendicular

Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.

So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 170 dollars.

The solution would still clear your concept though.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

[tex]c(x) = 18x -10[/tex]

The slope-intercept form of the line equation

We know that the slope-intercept form of the line equation

y=mx+b

where m is the slope and b is the y-intercept

so

[tex]c(x) = 18x - 10[/tex]

comparing with the slope-intercept form of the line equation

here:

and

'x' represents the number of tickets

Assuming the total cost i.e. c(x) = $170

In order to determine the value of x, set c(x) = 170

i.e.

170 = 18x -10

switch sides

18x - 10 = 170

add 10 to both sides

18x - 10 + 10 = 170 + 10

18x = 180

Divide 18 to both sides

18x/18 = 180/18

x =  10

Therefore, if you can buy x = 10 tickets if you pay  170 dollars.

The number line that represents opposite numbers is (a) number line 1

From the question, we understand that:

The numbers are opposite numbers

Take for instance, we have a number x.

The opposite of the number x is -x

So, the number line that represents opposite numbers must have points at x and -x

Let x = 10.

So, we have:

Opposite numbers = 10 and -10

So, the number line that represents opposite numbers must have points at 10 and -10

Hence, the number line that represents opposite numbers is (a) number line 1

Answer:

The value of the sales that week was £1,600

Step-by-step explanation:

The wage of a salesman is made of two parts: A fixed-wage of £160 per week plus a commission of 30%  (0.3) of the sales he makes that week.

The wage can be modeled by the function:

W = 160 + 0.3x

Where x is the amount of sales per week.

If he had a total wage of £640, then we can find the values of the sales by solving for x the equation

160 + 0.3x = 640

Subtracting 160:

0.3x = 640 - 160

0.3x = 480

Dividing by 0.3:

x = 480/0.3

x = 1,600

The value of the sales that week was £1,600

21 = 4x - 9 - x

21 = 3x - 9

30 = 3x

10 = x

Answer:

x = 10

Step-by-step explanation:

Given

21 = 4x - 9 - x, that is

21 = 3x - 9 ( add 9 to both sides )

30 = 3x ( divide both sides by 3 )

10 = x

Step-by-step explanation:

x^2+9x<-20

x^2+9x+20<0

( x+5)(x+4)<0

x+5<0,x+4<0

x<-4 (because x<-5 is extraneous solution)

Answer:

$0.18 sales tax will be added to the purchase price.

Step-by-step explanation:

Given that:

Cost of cupcake = $3

Sales tax applied = 6%

Amount of sales tax = 6% of cost of cupcake

Amount of sales tax = [tex]\frac{6}{100}*3[/tex]

Amount of sales tax = 0.06 * 3 = $0.18

Hence,

$0.18 sales tax will be added to the purchase price.

Step-by-step explanation:

(i) Using the law of cosines, we can find that

[tex]cos(O) = \frac{8^{2}+8^{2} - 7^{2}}{8*8*2}[/tex] ≈ 0.62, so O ≈ 0.9

(ii) Since the whole pie has 2π radians (or 360 degrees), we can divide 0.9 by 2π to get around 6.9 slices from the pie

(iii) The area of the shaded segment can be found by finding sector OAB and subtracting triangle OAB from that. Sector OAB can be found by finding the area of the pie (π*8², since 8 is the radius) and dividing that by 6.9, so we get 64π/6.9 ≈ 29. Then, the area of the triangle is √p(p-a)(p-b)(p-c), with p being the perimeter and a, b, and c being the sides. Plugging 7, 8, and 8 in, we get 25.1781 as our area, so the difference is around 3.8
