This is just a porportion. So if 250 meters is 1 meter than: 250/1

And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x

Set them equal to each other 250/1=212/x

Cross multiply: 212=250x

Divide to find x: 212/250=x
x=212/250
x=0.848

So the height of the model, to the nearest 10th would be 0.8 meters.

Plez halp with question bc im smol brain
Studentka2010 [4]

Answer:

B. y= 2x–15

Step-by-step explanation:

The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15

"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)

(8, 1) and (10, 5)

x in the first bracket is 8 and x in the second bracket is 10.

y in the first bracket is 1 and y in the second bracket is 5.

When this equation is applied to find the value for y we get:

y= 2x-15

y= 2(8)-15

y= 16-15

y= 1

y= 2x-15

y= 2(10)-15

y= 20-15

y= 5

We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)
