Step-by-step explanation:

\int \bigg( -  \frac{2}{7}  {x}^{3}  - 4 {x}^{4}  - 2x \bigg)dx \\  \\    = -  \frac{2}{7}\int    {x}^{3}dx  - 4 \int {x}^{4}dx  - 2\int x dx  \\ \\  =  -  \frac{2}{7}   \times \frac{ {x}^{4} }{4}  - 4 \times  \frac{ {x}^{5} }{5}  - 2 \times  \frac{ {x}^{2} }{2}  + c \\  \\  =  -  \frac{{x}^{4} }{14}    -  \frac{4}{5}  {x}^{5}  -  {x}^{2}  + c \\

Answer:  16) \bold{\sqrt{x}}        (17) \bold{\dfrac{x-4}{2}}        (18) \bold{\sqrt{x}-2}       (19)  3x - 18

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's and then solve for y

16) Given: y = x²

Swapped: x = y²

                \bold{\sqrt{x} =y}

17) Given:  y = 2x + 4

Swapped: x = 2y + 4

            x - 4 = 2y

            \bold{\dfrac{x-4}{2}=y}

18) Given:  y = (x + 2)²

Swapped: x = (y + 2)²

               √x = y + 2

        \bold{\sqrt{x}-2=y}

19) Given:  y=\dfrac{1}{3}x+6

Swapped: x=\dfrac{1}{3}y+6

            x - 6 = \dfrac{1}{3}y

            3(x - 6) = y

            3x - 18 = y

Mia is thinking of a 3 digit number. When she rounds the number to the nearest 10, it rounds to 750. If she adds 1 to the number
sweet [91]

Answer:

754

Step-by-step explanation:

If the number in the one's place is 5 or greater, the number is rounded up to the next ten. If the number is less than 5, the number gets rounded down.

754 is the answer because it rounds down to 750 as it is, but if 1 was added to it, it'd be 755 which would round up to 760.

X=9y<br> 5x+3y= -48<br> What does x equal?<br> What does y equal?
Anon25 [30]

you can plug the x value (9y) into the second equation

5(9y) + 3y = -48

45y + 3y = -48

48y = -48

y = -1

x = 9(-1)

x = -9
