What is the slope and y-intercept form for : y=-2/4x+5 PLEASE HELP IT WOULD ME SO MUCH THANK YOU!!!!
ddd [48]

Answer:

  y = -1/2x +5

Step-by-step explanation:

Slope-intercept form is ...

  y = mx + b

Matching this to the equation you have, you see that ...

  m = -2/4 = -1/2

  b = 5

The equation is already in slope-intercept form. The fraction that is the slope can be reduced, but that is not essential to the form.

Tony made $396 for 18 hours of work at the same rate how many hours would he have to work to make $198
tresset_1 [31]

Answer:

9 hours.

Step-by-step explanation:

So, first, you have to determine what he makes per hour to make this as easy as possible. You need to first do 396 divided by 18, which gives you 22. He makes 22$ an hour. Next, now that you know what he makes, you can do 198 divided by 22, and that'll show how long he has to work to make that amount of money.

Hope this helped. Please mark this brainliest if you think this helped. Let me know if you need anymore help and I am more than happy.

fiasKO [112]

Correct choice is B

Step-by-step explanation:

In step 4 were proved that \triangle ABC\sim\triangle DEC.

By definition, similar triangles have proportional lengths of corresponding sides. To the side AB corresponds side ED, to the side AC corresponds side DC and to the side BC corresponds side EC. Thus,

\dfrac{AC}{DC}=\dfrac{BC}{EC}.
