A photograph was enlarged to a width of 15 inches. If the scale factor was 3 /2 , what was the width of the original photograph?

1 answer:

6 0

If the width is 15, and the scale factor from width to length is 3:2, then you will have to divide 15 by 3 to get your original width.
15/3 = 5.
5 is your original width.

Which of the following systems of inequalities represents the graph?

mixer [17]

Answer:

Option D.

Step-by-step explanation:

Consider the below figure attached with this question.

If a line passes through two points $(x_1,y_1)$ and $(x_2,y_2)$ , then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

From the below figure it is clear that the a solid line passes through the points (-2,0) and (0,4). So, the equation of related line is

$y-0=\frac{4-0}{0-(-2)}(x-(-2))$

$y=2(x+2)$

$y=2x+4$

$-2x+y=4$

All area above the solid line is shaded. It means the sign of inequality is ≥.

$-2x+y\geq 4$

From the below figure it is clear that the a dashed line passes through the points (2,0) and (0,2). So, the equation of related line is

$y-0=\frac{2-0}{0-(2)}(x-(2))$

$y=-1(x-2)$

$y=-x+2$

$x+y=2$

All area below the dashed line is shaded. It means the sign of inequality is <.

$x+y$

System of inequality is

$-2x+y\geq 4$

$x+y$

Therefore, the correct option is D.

You can set up rations to do this.
So we know that they accept 2:5.
So It would be 180: 450.
