What is the solution to this system of equations?

Mathematics

mixas84 [53]2 years ago

Answer:

(-2,4)

Step-by-step explanation:

The solution is the point at which the two lines intersect, (-2,4).  That point is the only one that satisfies (works) in both equations:

y = x + 6

4 = -2 + 6

and

y = -0.5x + 3

4 = -0.5(-2) + 3

4 = 1 + 3

====

You can also solve it algebraically:

y = x + 6

y = -0.5x + 3

-0.5x + 3 = x + 6   [Use the value of y from the second equation in the first equation]

-1.5x = 3

x = -2

Use this is y = -2 + 6:

y = 4

(-2,4)

Answer:

B) angle B

Step-by-step explanation:

Since the question is telling you that both the triangles are essentially the same, you just have to look to see which letter of triangle ABC is in the same general place as triangle DEF.

In this case angle B is in the same general spot as angle E, so therefore B is your answer.

Hope this helps you :)

Find the slope through the given points Show your work. (2, 3) and (-5, 4)
belka [17]
The answer is (7,-1).

x1-y1 and x2-y2 gives you 2-(-5) and 3-4, so you now have a point which is (7,-1) which is the slope.

REY [17]
Congrats on getting that far!

From here, simplify the equation by dividing each term by the greatest common factor: 6.

36B + 30C = 822600 becomes 6B + 5C = 137100

Now you have stackable simultaneous equations that you can easily work with:

6B + 5C = 137100

B + C = 24500

Multiply the terms in the second equation by either 6 or 5 so that you can subtract the second equation from the first equation and cancel out the B or C, respectively.

Example:

6B + 5C = 137100

minus 5B + 5C = 122500

equals B = 14600

Then plug your answer into the B + C = 24500 equation to find C.

Finally plug B and C into the A + C + B = 49000 equation to get A.
