A billiards table is twice as long as it is wide . If the perimeter of a billiards table is 24 feet , what is the length and wid

th of the table ?
Mathematics

Answer:

Length=8     Width=4

Step-by-step explanation:

Step 1- make an equation. The equation for perimeter is usually 2l+2w=P, but since the length is twice as long, we'll 2l x 2 =4l. So our equation is

4l + 2w = 24. note that 8+16 = 24

Step 2- Since 16 is 8 x 2, we know that the length is 16 and width is 8. We divide both those numbers because there is 2 lengths and 2 widths.

Answer:

B) 1

Step-by-step explanation:

There are 8 pairs of data in the table but only 7 points plotted in the graph,

complette the square to get vertex form or y=a(x-h)^2+k
(h,k) is vertex
1. group x terms, so for y=ax^2+bx+c, do y=(ax^2+bx)+c <span> <span> </span> 2, factor out the leading coefinet (constant in front of the x^2 term), basicallly factor out a </span><span> <span> </span> 3. take 1/2 of the linear coefient (number in front of the x), and square it ,then add negative and positive of it inside parnthases </span><span> <span> </span> 4. complete the squre and expand </span>


so
y=-1/4x^2+4x-19
group
y=(-1/4x^2+4x)-19
undistribute -1/4
y=-1/4(x^2-16x)-19
take 1/2 of -16 and squer it to get 64 then add neg and pos inside
y=-1/4(x^2-16x+64-64)-19
factorperfect square
y=-1/4((x-8)^2-64)-19
expand
y=-1/4(x-8)^2+16-19
y=-1/4(x-8)^2-3
vertex is (8,-3)

Plz help wit number 5 will mark Brainiest
Nana76 [90]
The function is y=2x
this means that the solutions will have the form (x, y)=(x,2x).
For example: (0,0),(1,2),(2,4),(3,6) are solutions.
The first answer choice satisfies the above conditions.
The second answer choice contains (2,2), and (2,6), both of which do not satisfy the (x,2x) condition, so it's not correct.
The third answer choice contains (4,2), which again does not satisfy (x,2x), so not the right answer.
