Variation Constant: k = 7/6
y = 245/6 when x = 7 and z = 5
====================================
Explanation:
"y varies jointly as x and z" means that y = kxz
We have (x,y,z) = (4,14,3) as one triple, so,
y = kxz
14 = k*4*3
14 = 12k
12k = 14
k = 14/12
k = 7/6 is the variation constant
The equation goes from y = kxz to y = (7/6)xz
----------------
Plug in x = 7 and z = 5 to find y
y = (7/6)xz
y = (7/6)*7*5
y = (7/6)*(7/1)*(5/1)
y = (7*7*5)/(6*1*1)
y = 245/6
Divide the top by bottom. So 17 divided by 4. Which would be around 4.25
Answer:
y-2=1/3(x-3)
Step-by-step explanation:
Point slope formula: y-y1=m(x-x1)
m is slope.
y-2=1/3(x-3)
Hope this helps!
If not, I am sorry.
You can seperate it into two triangles then take the area of each of those (a=1/2bh) and add each triangles area together
