Answer:

-1.3

Step-by-step explanation:

The graph shows the straight line passing through the points (3,-1) and (-3,7).

The slope of the line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is

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

In your case, the slope is

$\dfrac{7-(-1)}{-3-3}\\ \\=\dfrac{7+1}{-6}\\ \\=-\dfrac{8}{6}\\ \\=-\dfrac{4}{3}\\ \\\approx -1.3$

The rate of change is -1.3

Y = –5x + 30<br> x = 10<br> What is the solution to the system of equations?

PtichkaEL [24]

Answer:

x=10, y = -20

Step-by-step explanation:

y = –5x + 30

x = 10

Substitute the second equation into the first

y = –5*10 + 30

y = -50 +30

y = -20

x=10, y = -20

State what additional information is required in order to know that the triangles are congruent by SAS

zalisa [80]

<h3>You are correct. The answer is the second choice.</h3>

BC = JC by the single tickmarks shown

CD = CD because of the reflexive property

The angles between these two pairs of sides, that you've marked in the second answer choice, are needed to use SAS (side angle side).

See the diagram below. In the diagram, angle BCD (green) is between segments BC and CD. Also, angle JCD (blue) is between JC and CD.
