Answer:

The first one is incorrect

Step-by-step explanation:

I only looked at the first one, and it's incorrect, the higher the wind speed is, the more likely the wave is to grow in size and speed. I can answer the rest if you want, but I'm assuming you're probably finished already.

4x-12y=-20 substitution method
worty [1.4K]

If we solve the equations x-2y=5 and 4x+12y=-20 then we will get x=1 and y=-2.

Given two equations x-2y=5 and 4x+12y=-20.

We are required to find the value of x and y through substitution method.

Equation is like a relationship between two or more variables expressed in equal to form. Equations of two variables look like ax+by=c. Equation can be a linear equation,quadratic equation, cubic equation or many more depending on the power of variable.

They can be solved as under:

x-2y=5---------------1

4x+12y=-20--------2

Finding value of variable x from equation 1.

x=5+2y--------------3

Use the value of variable  x in equation 2.

4x+12y=-20

4(5+2y)+12y=-20

20+8y+12y=-20

20y=-20-20

20y=-40

y=-40/20

y=-2

Use the value of variable y in equation 3.

x=5+2y

x=5+2*(-2)

x=5-4

x=1

Hence if we solve the equations x-2y=5 and 4x+12y=-20 then we will get x=1 and y=-2.

Question is incomplete as it should include one more equation x-2y=5.

ΔDEF is formed by lines tangent to the circle, where = 13.7, = 9, and = 14. Determine the perimeter of ΔDEF.
Dominik [7]

Answer:

Option (2)

Step-by-step explanation:

To solve this question we will use the property of tangents drawn to a circle.

"Tangents drawn from an external point to a circle are equal in length"

From the figure attached,

In ΔDEF,

DA = DC = 14 units [Equal tangents]

EA = EB = 13.7 units [Equal tangents]

FB = FC = 9 units [Equal tangents]

Therefore, DE = DA + AE = 14 + 13.7 = 27.7 units

EF = EB + BF = 13.7 + 9 = 22.7 units

DF = DC + FC = 14 + 9 = 23 units

Perimeter of ΔDEF = DE + EF + DF

                               = 27.7 + 22.7 + 23

                               = 73.4 units                            

Option (2) will be the answer.
