Tell whether the order pair is a solutionof the given system.(3,1) x+3y=6 4x-5y=7

1 answer:

3 0

If the ordered pair is a solution, then the two equations in the system should be true after we plug in the points, like so:

(3) + 3(1) = 6 and 4(3) - 5(1) = 7

Then you simplify. 3 + 3 = 6 and 12 - 5 = 7, therefore the ordered pair is a solution of the given system.

Find the slope of the line passing through the pair of points: (-6,-1), (-6,4)

Dima020 [189]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-6, -1) and (-6, 4).

Substitute:

$m=\dfrac{4-(-1)}{-6-(-6)}=\dfrac{4+1}{-6+6}=\dfrac{5}{6}\ !!!$

Dividing by 0 is not possible, therefore the slope is undefined.

It's a vertical line x = -6.

Find P(7). 1 2 3 4 5 6 7 8 where hand points to 3 1/8 1/4 1/2

ale4655 [162]

Answer:

1/2

Step-by-step explanation:

Every time clock moves 1 (like for example it move from 3 to 4) 1/8 it covers

3->4->5->6->7 => 1/8+1/8+1/8+1/8 => 4/8 => 1/2
