Factor using the x method
( please do not answer without showing work )
Answer:
[tex]5(x + 10)(10x - 3)[/tex]
Step-by-step explanation:
We are factoring
[tex]50x^{2} + 485x - 150[/tex]
So:
((2•5^2x^2) + 485x) - 150
Pull like factors :
50x^2 + 485x - 150 = 5 • (10x^2 + 97x - 30)
Factor
10x^2 + 97x - 30
Step-1: Multiply the coefficient of the first term by the constant 10 • -30 = -300
Step-2: Find two factors of -300 whose sum equals the coefficient of the middle term, which is 97.
-300 + 1 = -299
-150 + 2 = -148
-100 + 3 = -97
-75 + 4 = -71
-60 + 5 = -55
-50 + 6 = -44
-30 + 10 = -20
-25 + 12 = -13
-20 + 15 = -5
-15 + 20 = 5
-12 + 25 = 13
-10 + 30 = 20
-6 + 50 = 44
-5 + 60 = 55
-4 + 75 = 71
-3 + 100 = 97
Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 100
10x^2 - 3x + 100x - 30
Step-4: Add up the first 2 terms, pulling out like factors:
x • (10x-3)
Add up the last 2 terms, pulling out common factors:
10 • (10x-3)
Step-5: Add up the four terms of step 4:
(x+10) • (10x-3)
Which is the desired factorization
Thus your answer is
[tex]5(x + 10)(10x - 3)[/tex]
Answer:
[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]
Step-by-step explanation:
we would like to factor out the following expression:
[tex] \displaystyle {50x}^{2} + 485x - 150[/tex]
notice that, in every term there's a common factor of 5 thus factor it out:
[tex] \displaystyle 5( {10x}^{2} + 97x - 30)[/tex]
now we have to rewrite the middle term as sum or substraction of two different terms in that case 100x-3x can be considered:
[tex] \displaystyle 5( {10x}^{2} + 100 - 3x - 30)[/tex]
factor out 10x:
[tex] \displaystyle 5( 10({x}^{2} + 10)- 3x - 30)[/tex]
factor out -3:
[tex] \displaystyle \rm 5( 10x({x}^{} + 10)- 3(x + 10))[/tex]
group:
[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]
and we are done!
hence,
our answer is B)

How do I graph these points on a graph?
(-1/2, -3/2)
Answer:
Start at origin (0,0)
Move 1/2 units left
Move 1 and 1/2 units down
Place your point
Step-by-step explanation:
Start at the origin (0,0)
Move 1/2 units to the left
Then move 1 1/2 units down, and place your point.
The first coordinate is locating the position horizontally, or on the x axis
The second coordinate is locating the position vertically, or on the y axis.
If there is a negative number on the x coordinate, the first one, you move left.
If positive, you move right.
If there is a negative number on the y coordinate, the second one, you move down.
If positive, you move up.
If my answer is incorrect, pls correct me!

The graphs of linear functions fand g are shown on the grid.
which function best represented by the graph of g
Answer:
g(x) = 3f(x)
Step-by-step explanation:
We can see that for function g;
When x = 1, y = 3
When x = 2, y = 6
When x = -1, y = -3
When x = -2, y = -6
For function f;
When x = 1, y = 1
When x = 2, y = 2
When x = -1, y = -1
When x = -, y = -2
We can see that the output of g(x) is always 3 times that of f(x) for same values of x.
Thus;
g(x) = 3f(x)

Answer:
x=41
Step-by-step explanation:
so since this is a right triangle you can use the Pythagorean Theorem to find the missing side. the two sides you know are 'a' and 'b' and the missing side is 'c'. the theorem says that:
a^2+b^2=c^2
so:
9^2 +40^2=c^2
solve for the exponents:
81 +1600=c^2
1681=c^2
and now, since 1681 is the missing side's length squared, we must find the square root of 1681, which is 41

Answer:
The surface area of the parallelogram is;
2x^3 -6x^2 - 14x +24 squared centimeters
Step-by-step explanation:
To get the area of the parallelogram, we need to multiply the base length of the parallelogram by the height of the parallelogram
We have this as follows;
(x-4)(2x^2+2x-6)
= x(2x^2 + 2x-6) -4(2x^2 + 2x-6)
= 2x^3 + 2x^2 - 6x -8x^2 -8x + 24
= 2x^3 +2x^2 -8x^2 -6x-8x+24
= 2x^3 -6x^2 - 14x +24

Be specific, explaining how much the volume will change with each increase of 1 unit on the side lengths. Please give a clear explanation!
Answer:
When the dimensions of the shape, such as radius, height, or length change, both surface area and volume also change. However, the volume of the object always changes more than the surface area for the same change in dimensions.
