A is the point with coordinates (4 6)

B is the point with coordinates (d 12)


The gradient of the line AB is 3


Work out the value of d

Answers

Answer 1

Answer:

d = 6

Step-by-step explanation:

Given the coordinates A(4, 6) and B(d, 12) with the gradient of AB to be 3

Gradient m = y2-y1/x2-x1

Substitute the given values

3 = 12-6/d-4

3 = 6/d-4

Cross multiply

3(d-4) = 6

Expand

3d - 3(4) = 6

3d - 12 = 6

Add 12 to both sides

3d - 12 + 12 = 6 + 12

3d = 18

Divide both sides by 3

3d/3 = 18/3

d = 6

Hence the value of d  is 6

A 12 foot by 8 foot rug covers the hardwood floor of a room. The rug leaves a uniform
strip of bare floor surrounding the rug. If the area of the room is twice the area of the
rug, what is the equation you will use to solve for x?

Answers

Answer: 2(12 × 8)

Step-by-step explanation:

The area of the rug will be gotten by multiplying the length by its width. This will be:

= 12 foot × 8 foot

= 96feet²

Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:

= 2(12 × 8)

= 2(96)

= 192feet²

Consider the following geometric sequence

-5, 20, -30, 40, ...

If the explicit formula for the sequence above is expressed in the form aₙ = b*c^n-1, determine the values of b and c.

Answers

Answer:

b = -5 and c = -4

Step-by-step explanation:

The common ratio here is r = 20/(-5), or -4, and the first term, a(1), is -5.  Thus, the explicit formula is

a(n) = a(1)*r^(n -1)    (must use parentheses, as shown)

and so we have a(n) = -5*(-4)^(n - 1).  b = -5 and c = -4

Tickets for a carnival cost $8 for children 12 and under and $12 for anyone over the age of 12. The carnival sold 233 tickets and collected $2,156. How many children's tickets were sold?

Answers

Answer:

They sold 160 children's tickets.

Step-by-step explanation:

With the information provided, yoou can write the following equations:

x+y=233 (1)

8x+12y=2,156 (2), where:

x is the number of tickets for children 12 and under

y is the number of tickets for anyone over the age of 12

Now, you can solve for x in (1):

x=233-y (3)

Then, you have to replace (3) in (2) and solve for y:

8(233-y)+12y=2,156

1,864-8y+12y=2,156

4y=2,156-1,864

4y=292

y=292/4

y=73

Finally, you can replace the value of y in (3) to find x:

x=233-73

x=160

According to this, the answer is that they sold 160 children's tickets.

Answer:

Step-by-step explanation:

Since x=-2

-2+3y=4

Add 2 on both sides

3y=6

Divide 3 on both sides

y=2

Answer:

x is equal to -2

the equation is x + 3y = 4

so we substitute the value of 'x' which is -2 in equation x + 3 = 4

Step-by-step explanation:

then we move 3y on left side.

then we add 4 + 2 which is 6.

then it will be, y = 6/3

which is 2

therefore we get y = 2
