19. -x-2 = 2/3x + 3
5/3 x + 3 = -2
5/3x = -5
x = -3

20. none are correct, you can double check me by plugging in the x and y values in the coordanates into the first problem none of them worked out in the first equasion so no need to test the second

21. -3 is the answer, capable of being done by using desmos

If f(x) = 5x + 40, what is f(x) when x = –5?
kakasveta [241]

First note that f(x) means the same thing as y. To solve for f(x) or y you need to plug in -5 for x and solve using the rules of PEMDAS

5(-5) + 40

-25 + 40

15

When x is -5 then y is 15

Hope this helped!

yuradex [85]

Answer:

splitting it evenly among all three sides gives us the greatest area. ( for example if we had to split the number 10 into 2 and find the greatest area, out of all possible ways 5*5 is the greatest). Two sides have to be equal since it's a rectangle.

918/3=306

So we can make the two equal sides 306, and the longer side 308 which makes sure that we have the greatest area.

306 * 308
