Answer:

94cm

Step-by-step explanation:

wingspan         length

60 meters        70.5 m

----------------- = ----------------

80 cm                   x

Cross multiply

(60 m)x = (70.5 m)(80 cm)

Solve for x by dividing both sides of equation by 60 m:

x = (70.5 m)(80 cm) / (60 m) = 94 cm

The length of the model is 94 cm.

A+44=B<br> A=1x+76<br> B=-6x+134 <br> What is the value of A?
Rashid [163]
Hi there! A = 78

A + 44 = B
We can plug in the values of A and B into the equation. We then get an equation with only one variable (x), which we can solve.

1x + 76 + 44 = - 6x + 134
Collect terms.

1x + 120 = - 6x + 134
Add 6x to both sides.

7x + 120 = 134
Subtract 120 from both sides

7x = 14
Divide both sides by 7

x = 14 / 7 = 2

A = 1x + 76
Now plug in the value of x we just found

A = 2 + 76 = 78

What is the input if the output is 0 ?
Elodia [21]

In other words, what is <em>y</em> if <em>x</em> 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 <em>x</em> was 0 and the output <em>y</em> was -3 therefore,

\boxed{f(-3)=0}

Hope this helps.
