Answer:
y = 90
Step-by-step explanation:
If y varies jointly as x and z, then;
y = kxz
If y = 18 when x = 2 and z = 3
18 = k(2)(3)
18 = 6k
k = 18/6
k = 3
To get y when x = 5 and z = 6
y = kxz
y = 3(5)(6)
y = 15*6
y = 90
Hence the value of y is 90
Answer:
Step-by-step explanation:
<u>The given two points have same x- coordinates, hence the line vertical and is parallel to the y-axis:</u>
Its slope is undefined.
Answer:
f(3) = -11
Step-by-step explanation:
f(x) = -3x-2
let x=3 and replace it in the above equation
f(3) = -3(3) -2
f(3) = -9 -2
f(3) = -11
Answer:
1) pounds
2) grams
3) tons
Step-by-step explanation:
The suitable measurements for the scenarios are:
1) A piano weighs 5.5 × 10² units
550 Ib (pounds)
2) A grain of salt weighs 1.02 × units
0.00102 grams
3) A tractor trailer weighs 8.8 × units
88 ton
10²g = 1kg
10^-3g = miligrams
10^1 g = decagram
