For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b
a. ( 2b, 2b+7)
b. ( 2b, x + 7)
c.( x, x + 7 )
d. (x, 2b + 7)

A. (x,y)=(2b,2b+7)

Step-by-step explanation:

We have the function and we have to replace x=2b in the function.

Observation:

This means:

Then when x=2b, y=2b+7. The ordered pair corresponding to x=2b is

(x,y)=(2b,2b+7)

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
