Answer:

65 degrees.

Step-by-step explanation:

It's hard to explain, but I'll try:

The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do

180-140=40. The inside is 40.

And then 180-105=75.

Then you add the two and subtract them from 180:

40+75= 115

180-115=65

Voila!

Answer:

$y=3x-3$

Step-by-step explanation:

The equation of the line with the slope $m$ and passing through the point $(x_0,y_0)$ is

$y-y_0=m(x-x_0)$

In your case,

$m=3\\ \\x_0=3\\ \\y_0=6$

Hence, the equation of the line is

$y-6=3(x-3)\\ \\y-6=3x-9\\ \\y=3x-9+6\\ \\y=3x-3$

S is slope
S= rise/run
S1=3/12=1/4
S2=2/16=1/8
S3=5/15=1/3
S4=4/20=1/5

Which inequality statement best represents the graph?

Akimi4 [234]

Answer:

Step-by-step explanation:

If you have choices, you really should list them.

Here is the graph for y = (x + 0.25)(x - 1.75) which will look like yours. There are all sorts of variations that are possible, but at least I could reproduce a similar looking graph.

A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal?

aleksandr82 [10.1K]

Answer:

41 units

Step-by-step explanation:

Pythagorean's theorem,

Hypotenuse² = base² + adjacent²

Diagonal² = length² + width²

= 40² + 9²

= 1600 + 81 = 1681

Diagonal = √1681 = 41 units
