Y = 4/x
so when x = 1 y = 4/1 = 4
answer is A. (1,4)
14. B Add the equations
Since the equations have x and -x, if you add, it cancels out to 0 and x will be eliminated.
15. 7 weeks, $230 D
30x+20=20x+90
10x+20=90
10x=70
x=7
Plug x in
y=20(7)+90
y=140+90
y=230
16. B
4a+c= 60
a+c=27
16 children and 11 adults since 11+16=27 and 4(11)+16= 44+16=60
Answer:
A) rational number
Step-by-step explanation:
56 is a rational number because it can be expressed as the quotient of two integers like 56 ÷ 1.
If the length is taken as l , height is taken as h and breadth is taken as b . then
Area of the rectangular prism= 2( (l*b) + (b*h) + (h*l) )

The distance between the two points (-1, 4) and (5, 4) is 6 units.
<u>Step-by-step explanation:</u>
The given Coordinate points are (-1, 4) and (5, 4).
The points are considered as (x1,y1) and (x2,y2).
Here,
x1 = -1 and x2 = 5
y1 = 4 and y2 = 4
<u>The distance formula is given by :</u>
Distance =
<u>To find the distance between these two points :</u>
The distance formula is used,
Distance =
⇒ √(6)²
⇒ √36
⇒ 6
Therefore, the between the points is 6 units.
