den301095 [7]

Answer:

  (a) 100 Wacky News

  (b) 40 Daily News

Step-by-step explanation:

Multiplying the first ratio numbers by 4, we get ...

  daily : wacky = 8 : 20

and multiplying the second ratio numbers by 5, we get ...

  wacky : truthful = 20 : 5

Then we can combine these ratios to ...

  daily : wacky : truthful = 8 : 20 : 5

Multiplying this set of ratio numbers by 5 again, we get ...

  daily : wacky : truthful = 40 : 100 : 25

This makes the Truthful News ratio value match the actual number in part (a).

__

(a) If 25 Truthful News papers were sold on Friday, then 100 Wacky News papers were sold.

__

(b) The same day, 40 Daily News papers were sold.

Which graph shows a line with the same y intercept as the graph of 10x - 16y = 40
Amanda [17]

Answer:

The graph option where the y-axis is intercepted at y = -2.5 by the line of the graph.

Step-by-step explanation:

The answer choices for the possible graphs that have the same y-intercept as the graph of 10x - 16y = 40 is missing here.

However, the answer can still be explained here.

We can figure out how the graph would look like.

First, understand that the y-intercept of a graph is the value of y, of the point where the line intercepts the y-axis.

Let's figure out what the y-intercept is given a graph represented by the equation, 10x - 16y = 40.

Rewrite the equation in slope-intercept form.

10x - 16y = 40

-16y = -10x + 40

y = -10x/-16 + 40/-16

y = ⅝x - ⁵/2

Therefore, the y-intercept of the graph of 10x - 16y = 40 is -⁵/2 or -2.5.

✅The graph shows a line with the same y-intercept as the graph of 10x - 16y = 40, would have it's y-axis intercepted at y = -2.5.
