Answer:
The inverse function is
Step-by-step explanation:
Inverse of a function:
To find the inverse of a function, we exchange x by y, then we isolate y.
y = -4x
Finding the inverse:
So
The inverse function is
Answer:
x=60° , y=30° , z= 75°
Step-by-step explanation:
note...an equilateral triangle has the same angles all equal to 60°. so based on this x is 60°
the angle next to y is on a straight line therefore
60 +y =90
y=90-60
y=30°
the triangle with the y and z angles is an isosceles triangle...so the base angles must be equal
z+z+30=180
2z+30=180
2z=180-30
2z=150
z=75°
80p = 80 cents
£1.50 = $1.50.
(changing the signs, that's it)
So if a small bottle is half the size of a large bottle, and is 80 cents.
Amir buys 4 bottles, so 0.80 * 4 = 320 = $3.20.
Now 4 small bottles is the same as 2 large ones, so if he bought 2 large bottles: $1.50 * 2 = $3.00.
$3.20 - $3.00 = 0.20 cents.
Amir would've saved 0.20
P.S. What is "p" in European money
I hope this helps you
3^4/4.2^2/4.x^6/4.y^8/4=2^2/4.3^4/4.x^(c+2)/4.y^8/2
3.2^1/2.x^3/2.y^2=2^1/2.3.x^(c+2)/4.y^2
x^3/2=x^(c+2)/4
3/2=c+2/4
3.4/2=c+2
6=c+2
