Choose the correct graph to fit the equation. 4x - 3y = -1

Mathematics
1 answer:
VladimirAG [237]3 years ago
8 0
For this case we have the following equation:
 4x - 3y = -1

 We can rewrite the equation in the standard form of the line:
 y = mx + b

 Rewriting we have:
 3y = 4x + 1

 Clearing y we have:
 y = (4/3) x + 1/3

 We observe that we have a line with slope 4/3 and with a cut point with the axis y equal to 1/3

At the fast food restaurant, four cheeseburgers and five small fries have a total of 2,310 calories. Three cheeseburgers and two
Svetlanka [38]

<u><em>Answer:</em></u> <em><u>290 calories in a cheeseburger and 230 calories in fries.</u></em>

<em><u>x = calories in a cheeseburger</u></em>

<em><u>y =  calories in an order of small fries</u></em>

<em><u>Four cheeseburgers and five small fries have 2,310 calories. Therefore</u></em>

<em><u>4x + 5y = 2310       (1)</u></em>

<em><u>Three cheeseburgers and two small fries have 1,330 calories. Therefore</u></em>

<em><u>3x + 2y = 1330        (2)</u></em>

<em><u>Equations (1) and (2) model the given situation.</u></em>

<em><u>To solve, multiply (1) by 2, and multiply (2) by 5 to obtain</u></em>

<em><u>  8x + 10y = 4620          (3)</u></em>

<em><u>15x + 10y = 6650          (4)</u></em>

<em><u>Subtract (3) from (4).</u></em>

<em><u>7x = 2030</u></em>

<em><u>x = 290</u></em>

<em><u>From (1), obtain</u></em>

<em><u>5y = 2310 - 4*290 = 1150</u></em>

<em><u>y = 230</u></em>

<em><u> x = 290, y = 23</u></em>

<u><em>Hope this helps!</em></u>

Price for every 6 weeks= $ 156
Price for 1 week = 156/6 = $ 26

Assuming there are approximately 52 weeks in a year
Price for lessons per year = 26*52
= $1352

A student studied for 1 hour and earned a 50% on her test. If she had studied for 2
marshall27 [118]

You have to double 1 and 50 to get 2 and 100

1:50 = 2:100

1x2=2

50x2=100

So the statement, <em>if she studied for 2 hours, she would have gotten 100%</em>,  makes sense

Hope this helps!
