I have 3 questions First: "Mia is 18 and Nova is 33. In how many years will Nova be 3/2 of Mia's age" Second: "Alice is 9 years old, Brad is 12 years old/ In how many years will alice be 6/7 of brads age." Last: "A rectangle has a length that is 15 more than its width. A second rectangle with a perimeter of 72 has a width that is 5 wider and a length that is 2 shorter than the first rectangle. Find the dimensions of the first rectangle.

12 years

Step-by-step explanation:

Let's say the number of years we're looking for is x.

Nova's age: 33+x

Mia's age: 18+x

and of course: 33+x = 3/2 * (18+x)

This is an equation you can solve.

33+x = 3/2 x + 27

x - 3/2 x = 27-33

1/2 x = 6

x = 12

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
