I must assume that you meant the following:
10(Q-3R)
P = ----------------
R
Multiplying both sides by R, we get PR = 10R(Q-3R), or PR = 10RQ - 30R^2.
Rearranging these terms so that powers of R are in descending order:
30R^2 - 10RQ + PR = 0
Factoring out R, we get
R(30R - 10Q + P) = 0. This has two solutions:
R = 0, and 10Q - P
30R = 10Q - P, so that R = --------------
30
Answer:y=1/3x
Step-by-step explanation:
you know this by simply plugging in the x variable such as if you plug in the number 3, x=3 then your equation looks like y=1/3(3). when solving y=1 matching the graph.
The first thing we must do in this case is to calculate the surface area of the rectangular prism.
We have then:
A = 2 * ((L * h) + (L * w) + (h * w))
Where,
L: long
w: width
h: height
Substituting the values:
A = 2 * ((7.5 * 10) + (7.5 * 2) + (10 * 2))
A = 220
Then, "Manufacturing each box requires 10% more cardboard than the box's surface area"
Ar = 220 * 1.10
Ar = 242
242-220 = 22
Answer:
is needed 22 in ^ 2 cardboard to make each box
Hello,
not enough data:
y=k(x-3)²+0 With a point of the parabola, we can determine k.
