3 is the y-intercept

and -6 is the x-intercept

usually they don't have y behind the y-intercept so usually its the one that doesn't have x, they usually only put x.

The correct answer to this equation is X-inter=(-3.15,0) and Y-inter=(0,6.3) and heres why:

To solve this problem we must isolate the y-variable and then graph. Here are the steps to do that

$-6x+3y=18.9$ Now add 6x to both sides to get:

$3y=18.9+6x$ Next we divide both sides by the 3 next to the "y" to get: $y=\frac{18.9+6x}{3}\\$

Then you can simply graph this new equation to find your points. There is also another way to do it without graphing but it will take a lot more explaining and this way is faster.

If you find out that my answer is wrong, please tell me and I promise I will come back and rework my math. Thanks :)

Given the points (3, 0) and (-1, -3), which of the statements below is true?

nalin [4]

Answer:
We know the x-intercept only

Explanation:
To answer this equation, we need to go through the options individually and use both points to determine if they are true or false.

• Option 1 - False
According to the the first point given, we know the x-intercept is (3, 0).

• Option 2 - True
We only know the x-intercept. It is (3, 0) which is the first point given. We do not know the y-intercept.

• Option 3 - False
We do not know the y-intercept. We only know the x-intercept. In order to know the y-intercept the second point given must include a zero as the x point. The second point give does not include a zero. It is (-1, -3).

• Option 4 - False
We do not know the y-intercept

Judy is pulling on a trunk with a 12-N force. Ike pulls at right angles to Judy. With how much force must Ike pull to make the r

Ratling [72]

To understand the problem, let's first draw a free body diagram of the forces exerted by Judy and Ike on the truck. (Refer to the left side of the attachment).

To solve for the resultant, we just use the tip-to-tail method. This is illustrated on the right side of the attachment.

We can see that the tip-to-tail method forms a right triangle thus we can just apply the Pythagorean theorem in solving for Ike's force.

$20^{2} = 12^{2} + F^{2}$
$400 = 144 + F^{2}$
$256 = F^{2}$
$F = 16.0$

ANSWER: Ike must pull the truck with a force of 16.0 N.
