An orange costs x cent and an apple cost y cent more than the orange . Express the cost of 8 oranges and 12 apples in terms of x and y.

PL SOLVE THIS !!

8x+12y

Step-by-step explanation:

One orange costs xcent

8 oranges cost ?

Cross multiply

?=8x

One apple costs ycent

12 apples cost?

Cross multiply

?=12y

Combine the two together

8x+12y

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

(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.
