Answer:

y x (2x +y) x (7x +y)

Step-by-step explanation:

14x^2y + 9xy^2 +y^3

(Factor the expression)

y x (14x^2 +9xy +y^2)

(Rewrite the expression)

y x (14x^2 + 7xy +2xy +y^2)

(Factor the expression)

y x (7x x(2x +y) + y x (2x +y) )

(Factor the expression)

y x (2x +y) x (7x +y)

F(x) = x ^ 2 . What is g(x) ?
Bond [772]

Given:

The function is:

f(x)=x^2

The graphs of functions f(x) and g(x).

To find:

The function g(x).

Solution:

We have,

f(x)=x^2

The function f(x) is vertically compresses to get the graph of the function g(x). So, the function g(x) is:

g(x)=kf(x)

g(x)=kx^2               ...(i)

From the given graph it is clear that the graph of the function g(x) passes through the point (3,3). So, putting x=3 and g(x)=3 in the above function, we get

3=k(3)^2

3=9k

\dfrac{3}{9}=k

\dfrac{1}{3}=k

Putting k=\dfrac{1}{3} in (i), we get

g(x)=\dfrac{1}{3}x^2

Therefore, the correct option is D.

Shanta got 215 marks in an examination. if she had got 10 marks more, she would have scored 60% of the total marks. What are the
ololo11 [35]
She got 215....but if she would have gotten 10 more, she would have scored 60% of the total marks......so if she got (215 + 10) = 225 she would have scored 60% of the total marks...

so 60% of the total marks = 225
0.60x = 225
x = 225/0.60
x = 375 <===

Can somebody please help m eits 9th grade math im so confused !
prisoha [69]

Answer:

Option 3: (5, 1)

Step-by-step explanation:

There are several ways of solving for systems of linear equations, either through graphing, substitution, or elimination.  

The graphing method is the easiest, as you only need to plot points on the graph using the y-intercepts and the slopes.  

I will be demonstrating the <u>graphing method</u>.  

Given the systems of linear equations:  

Equation 1:  y = x - 4

where the <u>slope</u>, <em>m</em> = 1, and <u>y-intercept </u>(0, -4).

Equation2: y = -x + 6

where the <u>slope</u>, <em>m </em>= -1, and <u>y-intercept</u> (0, 6).

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b).

<h3>Graphing Instructions:</h3>

For Equation 1, plot the y-intercept, (0, -4) on the graph. Then use the <u>slope</u>, m = 1 (rise 1 unit, run 1 unit) to plot other points on the graph. Repeat this process until you have enough points to connect a line with.  

Repeat these same procedures for graphing Equation 2, start by plotting its y-intercept at (0, 6), and its slope, m = -1 (down 1 unit, run 1 unit).

<h3>Solution: </h3>

The intersection of both lines occurs at point, (5, 1), which is solution to the given systems of linear equations.  Therefore, the correct answer is the third option, (5, 1).

Attached is the screenshot of the graphed systems of linear equations, where it shows the point of intersection at (5, 1).
