Could someone please help me with #7 and #8?

2 answers:

7 0

7. Plug in 3x + 8 for y in second equation
2(3x + 8) = 6x + 16
6x + 16 = 6x + 16
It would be all solutions

8. Plug in 4x + 5 for y in second equation
12x - 3(4x + 5) = 9
12x - 12x - 15 = 9
12x cancels out
-15 = 9
There would be no solution

Answer: I'm not sure If i'm right because I did this since 8th grade.

For number 7, I think it would be (the equation form)= 6 x + 16

For number 8, I think it would be nothing because there is no solution.

Hope this helps:)

Find the exact angular velocity in radians per hour wind W= 4.1 rpm

nataly862011 [7]

Answer:

1545.66 rad/h

Step-by-step explanation:

We need to find the angular velocity in rad/hour when wind is moving with a speed of 4.1 rpm.

We know that,

1 revolution = 2π rad

1 hour = 60 minute

So,

$4.1\ rmm = 4.1\times \dfrac{2\pi }{(\dfrac{1}{60})}\ rad/h\\\\=1545.66\ rad/h$

So, the required angular velocity is 1545.66 rad/h.

Find the midpoint of the line using the midpoint formula.<br> Midpoint of AB:______

dimaraw [331]

Answer: MP=(1,1)

Step-by-step explanation:

$MP= (\frac{x_1+x_2}{2})(\frac{y_1+y_2}{2})$

$MP= (\frac{-2+4}{2})(\frac{-3+5}{2})$ -2+4=2 -3+5=2

$MP= (\frac{2}{2})(\frac{2}{2})$ 2/2=1

$MP= (1,1)$
