WILL GIVE BRAINLIEST PLEASE HELP NOT A TIMED TEST more than on answer possible
If f(x) = 2x - 9, which of the following are correct?

f(-1) = -11

f(2) = 5

f(3) = -3

f(0) = -9

f(-3) = 15

f(-1)=-11,f(3)=-3,f(0)=-9

Step-by-step explanation:

by substitution of -1,3,0then will get answer

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
