Answer:

False

Step-by-step explanation:

This is because if you have a function which is Y=2x-4 , then trying to give an example using the given points which (3,2) , here we will have Y=2 upon replacing 3 in the function cause 3 is the value of x and vice versa if we have 2 as the value of Y then x will be 3 . However,if we get the (1,2) the answer for Y will be -2 which is different from the one we have in the question hence this concludes false

Quadrilateral RJFT is similar to quadrilateral SYPA . JF=60 mm , AP=40 mm , and YP=25 mm . What is TF ?
Hoochie [10]
The two quadrilaterals are similar. Which means the ratios of respective sides of two quadrilaterals will be the same. 

So, for the given quadrilaterals, ratio of sides JF and TF of quadrilateral RJFT will be equal to the ratio of sides YP and AP of quadrilateral SYPA. Mathematically, we can write:

JF:TF = YP:AP \\  \\ 
 \frac{JF}{TF} = \frac{YP}{AP}  \\  \\ 
 \frac{60}{TF} = \frac{25}{40}  \\  \\ 
60* \frac{40}{25}=TF \\  \\ 
TF=96mm

So the measure of TF will be 96mm

A scale drawing of a building has the scale 0.5in : 6ft. A wall is 30 ft long. How long will the wall be on the drawing?
g100num [7]
The scale 0.5 in : 6 ft, means that

any distance of 0.5 in on paper, represents 6 ft in reality


for example:
 
0.5*2= 1(in) represents 6*2=12 (ft)

0.5*4= 2(in) represents 6*4=24 (ft) 

0.5*10=5(in) represents 6*10=60 (ft) and so on...


Let the wall be x (in) in the drawing:

0.5 (in) represents 6 (ft),
 x (in) represents 30 (ft)
----------------------------------------

thus x = (0.5*30)/6 = 15/6= 2.5 (in)


Answer: 2.5 in
