Answer:

1.6 ft

Step-by-step explanation:

If you use the Pythagorean Theorem to solve for x, you get:

$x=\sqrt{2.1^2-1.4^2}$

$x=\sqrt{2.45} = 1.56524758425$

Rounded to the nearest tenth, the answer is 1.6

Now try 50 for x. If x=50,what I'd y when y=x-20? Does that work with the other equation?

X= 50
Replace the x with the given number.
Y= 50-20
Y= 30

Please someone do this for me

nlexa [21]

Answer:

A = -12

B = -8

C = -4

Step-by-step explanation:

$y=2x-8$

x = -2

$y=2(-2)-8=-4-8=-12$

A = -12

x = 0

$y = 2 (0)-8=-8$

B = -8

x = 2

$y = 2 (2) -8 = 4-8 = -4$

C = -4

What is the input if the output is 0 ?

Elodia [21]

In other words, what is y if x is 0.

Look on the graph, a line passes through point, $A(x,y)\longrightarrow A(0,-3)$

So we can conclude that at that very point the input x was 0 and the output y was -3 therefore,

$\boxed{f(-3)=0}$

Hope this helps.
