Is y= 19x - 5 proportional or non-proportional

Answer:

The given equation of the line is non proportional.

Step-by-step explanation:

If y is proportional to x then it will be represented by y ∝ x

Or y = kx where k = proportionality constant

And this linear equation when graphed, the line passes through (0, 0) and there will be no y-intercept.

But the equation y = 19x - 5 given in the question shows the y intercept of (-5).

Therefore, this equation can not show the proportionality relation between x and y. It's non proportional.

non-proportional because it has a y-intercept

Find the value of x.
zepelin [54]

Answer:

Step-by-step explanation:

Using the Z theorem, the upper  angle on the right = 60 degrees.

The angle which includes 3x is 120  because this is a parallelogram and consecutive angles must add to 180. So 180 - 60 = 120

The angle above the 3x is 120 - 3x

120 - 3x + 90 + 2x = 180 These angles make a straight line line. Combine.

210 - x = 180                    Subtract 210 from both sides.

- x = 180 - 210                  Combine

-x = - 30                           Multiply both sides by - 1

x = 30

Akayo claims that there are centers of dialstiond through ehich a dialation of line n by a factor of 1.5 leaves line n unchanged
mars1129 [50]

Answer:

See Explanation

Step-by-step explanation:

This question requires further details. In absence of the details, I will answer on a general term.

When a line is dilated (whether expanded or compressed), the new line will be on the same line with the dilated line; however, the length of both lines will be different

Take for instance:

<em>Line AB of coordinate (1,3) is horizontally dilated by 2, </em>

<em>Horizontal dilation rule is: y = f(cx) where c is the dilation factor</em>

<em />

<em>So, the new point will be </em>

<em>A'B' = (1, 3 * 2)</em>

<em>A'B' = (1,6)</em>

<em />

<em>When you compare the x coordinate of both line, you will observe that they have the same x coordinate of 1. </em>

<em>This implies that they are on the same level but different length</em>

<em />

The same is applicable to vertical dilation

<em />

<em>the new point will be:</em>

Tanisha's plant is 9 7/10 cm tall.
neonofarm [45]

Answer:

5 3/10

Step-by-step explanation:

9 7/10 = 97/10

4 2/5 = 4 4/10 = 44/10

97/10 - 44/10 = 53/10

53/10 = 5 3/10
