Answer:

<em>D.</em>

Step-by-step explanation:

The number lines goes by the scale of 0.1 per each line, meaning that if the dot is one line after 0, then the dot is 0.1. This can be interpreted by counting the number of lines from one number to another.

A. is 0.5

B. is 0.7

C. is 0.6

D. is 0.4

So, the correct answer is D.

4/10 = 0.4

The only line that proves this is line d.

Hope this helps!

Let f(x)=4x+9. Write a function g whose graph is a reflection in the y-axis of the graph of f. g(x)= ?
frez [133]

Answer:

g(x)=-4x+9

Step-by-step explanation:

So we know that:

f(x)=4x+9

To reflect across the <em>y-axis</em>, instead of x, use -x. Therefore:

g(x)=f(-x)=4(-x)+9

Simplify:

g(x)=-4x+9

And that's our answer :)

(2x + y)2 – (3x – 2y)2 + (x – 4y)(x + 4y<br>11​
Vinvika [58]

Answer:

Step-by-step explanation:

(a+ b)² = a² +  b² + 2ab

(2x + y)² = (2x)² + y² + 2*2x *y

             = 4x²  + y² + 4xy

(a- b)² = a² + b² - 2ab

(3x - 2y)² = (3x)² + (2y)² - 2*3x *2y

              = 9x² + 4y² - 12xy

(a - b)(a +b) = a² - b²

(x - 4y(x + 4y) = x² - (4y)²

                     = x² - 16y²

(2x + y)² - (3x - 2y)² + (x - 4y)(x +4y)

  = 4x²  + y² + 4xy - (9x² + 4y² - 12xy) + x² - 16y²

  = 4x²  + y² + 4xy - 9x² - 4y² + 12xy + x² - 16y²

  = 4x² - 9x² + x²  + y² - 4y² - 16y²+ 4xy + 12xy

 =    -4x² - 19y² + 16xy

Step-by-step explanation:

the equation ofa line in slope-intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = 1 and c = 3, hence

y = x + 3 ← is the equation of the line
