Algebra help please?

Mathematics
1 answer:
Alika [10]3 years ago

Ok, basically if you want to find when both equations are equal just make them equal to each other. 0.925x^2 - 4x + 20  = -1.125x^2 + 6x + 40.

From there use algebraic steps to find out what x is ( the break - even point ).

0.925x^2 - 4x + 20 = -1.125x^2 + 6x + 40

0.855625x - 4x + 20 = 1.265625x + 6x + 40

-0.41x - 4x + 20 = 6x + 40

-4.41x + 20 = 6x + 40

20 = 10.41x + 40

-20 = 10.41x

-1.92122958694 = x

Rounded to the nearest tenth it's -1.9 = x.

Tell me if I got something wrong :)

7(x+2)

Let's find the common term in this expression to factor it out. it is 7.

Factoring is the opposite of distributing.

If we distribute, we will get the original expression.

Next:

45-27k

Here, the common term is 9:

9(5-3k)

12ab+7b - the common term is b:

b(12a+7)

y^2-9y.

Here the common term is y:

y(y-9)

8r-32r² the common term here is 8r:

8r(1-4r)

16gh+28gh: the Common Term is 4gh:

4gh(4+7)

21w²-77wx The common term is 7w:

7w(3w-11x)

Hope it helps! Please mark Brainliest! =)

The slope of the line ​
rjkz [21]
Answer:
-3 or -3/1
Explanation:
It’s going down so it will be negative, it’s always rise over run so rise would be -6 (even tho it goes down which is why it’s a negative) run would be how much it goes over so it would be 2, so it’s -6 over 2 , but then you make the number smaller (simplify) , divide both sections by 2, it would come out to -3 over 1 but the one basically goes away

A surveyor starts at the southeast corner of a lot and
elena-s [515]

Find the difference vertically( North and South) and the difference horizontally ( East and West)

Then use  the Pythagorean Theorem.

600 North - 200 South = 400 m

400 West - 100 East = 300 m

Now using the Pythagorean Theorem;

400^2 + 300^2 = total displacement^2

Total displacement^2 = 160,000 + 90,000

Total displacement^2 = 250,000

Total displacement = √250,000

Total displacement = 500 m
