Hello,

Solving Process:
1. Isolate y
2. Make coefficient of y equal 1

Steps:
1. (2y - 4x) / 2 = 18 / 2
2. y - 4x = 9
3. y = 4x + 9 <<<<

Good luck to you!

I need help with this word problem please ​
Anika [276]

Answer:

-60 m/s²

Step-by-step explanation:

We are not given the velocity of the plane at landing but we are given velocities at two time periods

V₅, the velocity of the plane 5 seconds after landing is 110 m/s

Plugging this into the velocity equation we get

\bold{v_5 = a.5 + v_0 = 5a + v_0}                (1)

Similarly

\bold{v_{15} = a.15 + v_0 = 15a + v_0}           (2)

Subtract (1) fromv_{15} - v_5 = (15a + v_0) - (5a + v_0) = (15a-5a) + (v_0-v_0) = 10a

Therefore a = \frac{v_{15} - v_5}{10}

Given v_{15}= 50 m/s \textrm{ and } v_5 = 110m/s

this evaluates to

a = (50-110)/10 =  -60 m/s²

The negative value is because the plane is actually decelerating which is a negative number

In the following exercises, simplify each expression.
jasenka [17]

Answer:

The answer would be 8.3*10^7.

Step-by-step explanation:

This is because the beginning factor in scientific notation (in this case it is 8.3) must be no less than one, and no more than ten. Once we figured that out, we simply count the number of decimal points from 3 to the final 0. Try it yourself. You will discover that the resulting answer is 7 decimal movements. Now, since we are using scientific notation, we will want to multiply by ten to the power of the number of decimal movements (in this case it is 7.) And that's all! The answer is 8.3*10^7. I hope this helped (:

Answer:

4

Step-by-step explanation:

The ratio is 1:2

The longer side ratio is 4:8 so that is how I got it

The shorter side would be 2:X.  X=4
