Answer:
£60
Step-by-step explanation:
Let the original cost be x.
x × (1 - 20%) = 48
0.8x = 48
x = 48/0.8
x = 60
The original cost was £60 before the sale.
Answer:
Ex 1: f(2)-f(1)+f(1÷2)=9÷4
Step-by-step explanation:
f(2)=2²-2×2+2=4-4+2=2
f(1)=1²-2×1+2=1-2+2=1
f(1÷2)=(1÷2)²-2×(1÷2)+2=5÷4
Answer:
The y-intercept is (0,1)
Step-by-step explanation:
So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).
Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.
y-7=3(0-2)
y-7=3(-2)
y-7= -6.
-6+7= 1, so y=1
The ordered pair is then (0,1). Hope this was useful :)
