6x + 7y = 4x + 4y
y = -4
Step 2: Solve for x
Substitute: 6x + 7(-4) = 4x + 4(-7)Multiply: 6x - 28 = 4x - 28Add 28 on both sides: 6x = 4xSubtract 4x on both sides: 2x = 0Divide both sides by 2: x = 0Answer:

In sailing, it is not possible to head straight into the wind. In order to get upwind, a sailboat simply sails at an angle to the wind and then turns to sail back toward where it wants to go. Assume that a boat needs to get directly upwind 6000 m. If it sails off at a 45 degree angle to the wind and then turns back 90 degrees towards the original goal, how far would it have to sail to get directly upwind 6000 meters? Round to the nearest tenth.
Distance to get directly upwind 6000 meters: ____________________ meters
6000
4242.6
8485.3
10392.3
Answer:
C. 8485.3 meters
Step-by-step explanation:
Think of the sailboat’s path as a 45-45-90 right triangle.
The hypotenuse is the 6000 meter distance.
In this way the leg will be the hypotenuse divided by √2.
So 6000/√2 or 4242.64 meters.
Remember that the sailboat has to turn and head back toward its goal and travel another 4242.64 meters.
Thus, your answer is 4242.64 x 2 = 8485.28 meters or 8485.3 meters.
In this exercise we have to use the knowledge of triangles to calculate the distance that one of the sides has:
Letter C
Some information given in the statement about the triangle:
Sailboat’s path as a 45-45-90 right triangle.The hypotenuse is the 6000 meter distance.So performing the calculation we have:
[tex]6000\sqrt{2}=4242.64 \\4242.64 * 2 = 8485.28[/tex]

Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t is measured in seconds. Which of the following gives the rate at which the area covered by the oil is changing at time t=10 ?
Answer:
By an online search, i found that the options are:
Option A. A(10)
Option B. A(11)-A(9)
Option C. A(10)/10
Option D. A’(10)
Let´s start by defining the concept of a derivative.
When we have a function f(x), the derivative, f´(x), is a measure of the rate of change of f(x) with respect to the variable x.
Then if A(t) represents the area covered by the oil, A´(t) is the rate of change of this area as a function of t.
Particularly, A´(10), will be the rate of change at t = 10.
Then the correct option is: Option D. A´(10)

They aren't parallel because the intersections with Via La Playa do not make equal alternate interior, alternate exterior angles, or corresponding angles.
Step-by-step explanation:
Angle a is 140 degrees since it and 40 degrees are supplementary. The angle supplementary to 130 degrees is 70 degrees. All of the vertical angles are congruent.

a. 34 in.
b.8 in.
c. 6 in.
d.30 in.
I NEEP HELPP FAST
Answer:
8 in
Step-by-step explanation:
Area of a square = l×w
Since it is a square then l and w are equal to each other.
So we can instead just say l^2 = A
l^2 = 68.2
l = square root of 68.2
l = 8.26

A light-year is a unit used to measure large distances in space. One light-year is approximately equal to 5.88 trillion miles. On a map of the Milky Way Galaxy, the scale is 1 inch:70 light-years. If two stars on the map are 19 inches apart, about how far apart are they in the galaxy?
Answer:
[tex]7.8204\times 10^{15}\ \text{miles}[/tex]
Step-by-step explanation:
In the map the scale is
[tex]1\ \text{inch}=70\ \text{light-years}[/tex]
So
[tex]19\ \text{inches}=19\times 70=1330\ \text{light-years}[/tex]
In miles
[tex]1\ \text{light-year}=5.88\times 10^{12}\ \text{mi}[/tex]
[tex]1330\ \text{light-years}=1330\times 5.88\times 10^{12}=7.8204\times 10^{15}\ \text{miles}[/tex]
The galaxies are [tex]7.8204\times 10^{15}\ \text{miles}[/tex] apart.
