X/y = 4 , x = 4y
x^2 -12y^2 = (4y)^2 - 12y^2 = 16y^2 -12y^2 = 4y^2
Step-by-step explanation:
load=1000N
effort=250N
load arm=25cm
effort arm=?
Now,
E×E.D=L×L.D
250×E.D=1000×25
E.D=1000×25÷250
E.D=100cm
therefore,effort arm is 100cm.
A quotient is a answer or the sum
A. y=6.50x+100
B. How many shirts were ordered
Answer:
Step-by-step explanation:
To find the inverse of a function, you want to replace x with y and y with x. Then, you solve for y.
[replace y with x and x with y]
[subtract both sides by 7/2]
[multiply both sides by -2/3]
[distribute]
Now, we have our inverse function.
