Answer:

$\large\boxed{q=\dfrac{40}{11}}$

Step-by-step explanation:

$-4q+9=7q-31\qquad\text{subtract 9 from both sides}\\\\-4q+9-9=7q-31-9\\\\-4q=7q-40\qquad\text{subtract }\ 7q\ \text{from both sides}\\\\-4q-7q=7q-7q-40\\\\-11q=-40\qquad\text{divide both sides by -11}\\\\\dfrac{-11q}{-11}=\dfrac{-40}{-11}\\\\q=\dfrac{40}{11}$

Answer:

q = 3.636363636 repeating

Step-by-step explanation:

- 4q + 9 = 7q - 31

+ 4q + 4q

9 = 11q - 31

+ 31 + 31

40 = 11q

$\frac{40}{11} = \frac{11q}{11}$

Answer:

$3y^{2}+2y-11$

Step-by-step explanation:

we have

$(-y^{2}-4y-8)-(-4y^{2}-6y+3)$

Eliminate the parenthesis

$-y^{2}-4y-8+4y^{2}+6y-3$

Group terms that contain the same variable

$-y^{2}+4y^{2}-4y+6y-8-3$

Combine like terms

$3y^{2}+2y-11$

IS ANYONE HERE GOOD AT CALCULUS?? IF SO, PLEASEEEE HELP ME!!!! An object’s velocity at time t is given by v(t) = –2 sin t. Let s

Bingel [31]

Answer: C

Step-by-step explanation:

Since we are given velocity, which is the first derivative, we have to fidn the antiderivative of velocity to get position.

∫-2sint dt

s(t)=2cos(t)+C

Since we are given s(0)=0, we can plug in the values to find C, constant.

0=2cos(0)+C

0=2(1)+C

0=2+C

C=-2

Now that we know our constant, we can find out position.

s(t)=2cos(t)-2
