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
I hope this helps so the first one should be right
Below is the solution:
<span>Using 2 equations:
Quantity: c + p = 10 lbs
Value::: 5.6c + 2.3p = 3.29*10 dollars
</span><span>Multiply thru the Quantity Eq. by 560
Multiply thru the Value Eq. by 100
</span><span>560c + 560p = 5600
</span><span>560c + 230p = 3290
</span><span>Subtract and solve for "p":
330p = 2310
p = 7 lbs (amt. of peanuts needed)
</span><span>Solve for "c" using c+p = 10
c + 7 = 10
c = 3 lbs (amt. of cashews needed)</span>
