Answer:

B

Step-by-step explanation:

Not A cause the ratios are different, as the first ratio is -1/3 and the rest are 1/3

B is correct cause the ratio is 1/3 and the first term is 1

Not C cause the ratio is not 1/3

Not D cause the ratio is 3

Have a nice day! :)

The graphed line shown below is y=-3x+6
Bezzdna [24]
<h2>Answer:</h2>

y=-3\left(x+6\right)

<h2>Step-by-step explanation:</h2>

From the given graph, we can know two points:

P_{1}(x_{1},y_{1})=(2,0) \ and \ P_{2}(x_{2},y_{2})=(1,3)

Using the slope intercept form of the equation of a line, we get:

y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1}) \\ \\ y-0=\frac{3-0}{1-2}(x-2) \\ \\ y=-3(x-2) \\ \\ y=-3x+6

Where the slope is m=-3 and the y-intercept is b=6

From mathematics, we know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept. So, from the options, the second equation is:

y=-3(x+6)

And the slope intercept form of this equation is:

y=-3x-18

So the slope is m=-3 and the y-intercept is b=-18, the systems formed by these two equations has no solution.

Determine the number of solutions for the system of equations y=2/3x+4 and y=2/3-x2
Phoenix [80]

2/3x+4=2/3-2x

2/3x-(-2x)

2/3x+2x

2 2/3x+4=2/3

2/3-4=-3 1/3

2 2/3x=-3 1/3

(3 1/3)/(2 2/3)=1 1/4

x = 1 1/4

y=2/3-2x

y=2/3-2(2/3)

y=2/3-4/3

y=-2/3

The answer is (1 1/4, -2/3)

Help me please ! Thank you so so much :)

#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side

#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS
