Answer:
5/2 , 5/-2
Step-by-step explanation:
0ne is :
4+2x-5=4
4+2x=4+5
2x=9-4
x=5/2
anf another is:
4+2x-5=4
4+5-4=-2x
9-4=-2x
5=-2x
5/-2=x
Answer:
The area of the sector BOC is A' = 31.4 
Step-by-step explanation:
Radius of the circle = 10 cm = 0.1 m
Angle of sector 
= 36°
Area of the circle A = 
A = 3.14 × 
= 0.0314 
Now area of the sector BOC is
A' = 0.00314 = 31.4
Therefore the area of the sector BOC is A' = 31.4
Answer:
80 sacks for $959.2
Step-by-step explanation:
2 tons = 4000 lbs.
If each sack cost $11.99, and is weighted at 50 pounds than
4000/50 = 80
80 x $11.99 = $959.2
Answer:
f⁻¹(x) = x/4 + 1/2
Step-by-step explanation:
To find the inverse of a function, switch the x and y variables, then isolate y.
f(x) replaced y, so you can replace it back.
y = 4x - 2
x = 4y - 2 Switched x and y
x + 2 = 4y Added 2 to both sides
y = x/4 + 2/4 Divided both sides by 4
y = x/4 + 1/2 Simplified
f⁻¹(x) = x/4 + 1/2 Use function notation
