X=25
4x-10=90
Add 10 to both sides
4x=100
Divide both sides by 4
9514 1404 393
Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²
Answer:
x= −5
/3
Step-by-step explanation:
This equals: x^3 + 5x^2 - 4x - 20
making the degree 3, the LC 1, and the y-int 20
hope this helps
Answer:
It is linear because the ratio of the change in the final cost compared to the rate of change in the price tag is constant.
