a) The value of x is 42.6 when k =16/3 is directly proportional to y.
b) The value of x is -56 when k is -7 is directly proportional to y.
What kind of variation is one where x and y are directly proportional?
If x = ky for some constant k can be used to indicate the relationship between the variables y and x, then we may say that y varies directly with y or that x is directly proportional to y.x varies directly as y
x α y
x = ky
a) x=6 ; y = 32
x = ky
6 = k(32)
k = 16/3
if y = 8
then,
x = (16/3) * 8
= 128/3
x = 42.6
Hence, the value of x is 42.6 when k =16/3 is directly proportional to y.
b) x= 14 and y = -2
x = ky
14 = k(-2)
k = -7
if y = 8
then,
x = ky
x= (-7) 8
x = -56
Hence, the value of x is -56 when k is -7 is directly proportional to y.

A store sells 8 cans of for $22. How much would it cost you to buy 3 cans of fruit cocktail? ?
the answer is 8.25 or 8 1/4
you can get this by dividing 22 by 8 to see the price for one can. this gives you 2.75
now you want to know how much 3 cans would cost. we know one can costs 2.75, so we multiply that by 3.
this would give you 8.25 which is your answer

If an object is projected upward into the air from ground level, then the height h(t) of the object
in feet at time t in seconds is given by:
h(t) = -16t^2+ 344t
How long does it take for the object to hit the ground? SHOW ALL WORK clearly and neatly - do not skip
steps. The show all work part cannot be stressed enough.
Answer:
21.5secs
Step-by-step explanation:
Given the function that models the height of an object as
h(t) = -16t^2+ 344t
The object hit the ground at h(t) = 0
Substitute
0 = -16t^2+ 344t
16t^2 = 344t
16t = 344
t = 344/16
t = 21.5
Hence it takes 21.5secs for the object to hit the ground

Solve for x using
cross multiplication.
x 1 = 2x + 4 5
x = [?]
Answer:
x = -7
Step-by-step explanation:
Given:
[tex] \frac{x - 1}{4} = \frac{2x + 4){5} [/tex]
Required:
Find x using cross multiplication
Solution:
Cross multiply
(2x + 4)*4 = (x - 1)*5
8x + 16 = 5x - 5
Collect like terms
8x - 5x = -16 - 5
3x = -21
Divide both sides by 3
x = -21/3
x = -7

In ΔPQR, sin P = 0.3, sin R = 0.8 and r = 16. Find the length of p. Please show your work.
Answer:
p = 6Steps:
sin(P)/p = sin(R)/r
given: sin(P) = 0.3 , sin(R) = 0.8 , r = 16
0.3/p = 0.8/16
0.3/p = 8/10×1/16
0.3/p = 8/160
0.3/p = 1/20
p = 3/10×20
p = 60/10
p = 6
