Which equation has a graph that is a parabola with a vertex at (1,HI)? Oy=(-12+1
O y--1-
O y=(«+ 1) +1
O y=x+1)-1

Step-by-step explanation:

Given

Required

Determine the equation

The equation of a graph from a vertex is:

Where

Substitute these values in

Express -(-1) as 1

Express +(-1) as -1

Hence, the equation is:

at home andrea has 1 2/3 kilograms of rice

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
