X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7

x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19

The sides are 12, 14, and 19 cm. long. Hope this helped!

Graph the system below and write its solution.
Diano4ka-milaya [45]

Answer:

See the graph attached. It has one solution: (6,-4)

Step-by-step explanation:

The slope-intercept form of a line is:

y=mx+b

Where m is the slope and b is the intersection of the line with the y-axis.

Given the first equation  y =\frac{-1}{2}x -1

You can identify that:

b=-1

Substitute y=0 to find the intersection with the x-axis

0 =\frac{-1}{2}x -1\\1(-2)=x\\x=-2

This line passes through the points (0,-1) and (-2,0)

Given the second equation:

-2 + y = -6

Solve for y:

y = -6+2\\y=-4

It passes through the point (0,-4).

Now, you can graph. See the figure attached.

It has one solution,which is the point of intersection of both lines:  (6,-4)

The equation y = x + 1 defines the relationship between x and y, where x is the input and y is the output. Which statements abou
vichka [17]
Hey there!

Let's go through all of our options.

A) It's defintely not curved; it's written in slope intercept form and is indeed a straight line.

B) Yes, the graph is a straight line. Although it's at an angle, it has no curves or flaws, and is completely straight.

C) The graph is not vertical. It has a y intercept and slope and therefore isn't. That's because it has a rate of change, and it crosses the y axis at some point depending on the slope, or rise over run. Vertical lines really don't have that.

D) Yes, the graph is a function. This is because it does not have two x values for one y, and does not fail the straight line test, which states that you can place a straight line anywhere on the graph and it can only go through one point.

E) This is false. If we put in -5 as our input, we add 1 and get -4, which is a negative output. Your output here depends on the input you put in, and the sign usually remains considering it's +1.

F) This graph does not pass through the origin. This is because the origin has a point at 0,0 and since it's x+1, it would be 0,1 instead because your output is adding one to that 0.

Hope this helps!
