Which point is NOT on the line y = 5x + 1?
12345 [234]

To find which point is NOT on the line y = 5x + 1, we just need to plug each point into equation y=5x+1 to see which one point satisfies this equation.

check for (1,6)

y=5x+1

or 6=5*1+1

or 6=5+1

or 6=6

Which is TRUE.

--------

check for (2,11)

y=5x+1

or 11=5*2+1

or 11=10+1

or 11=11

Which is TRUE.

--------

check for (0,1)

y=5x+1

or 1=5*0+1

or 1=0+1

or 1=1

Which is TRUE.

--------

check for (-1,6)

y=5x+1

or 6=5*(-1)+1

or 6=-5+1

or 6=-4

Which is FALSE.

--------

Since only point (-1,6) fails to satisfy the given equation hence point (-1,6) is the final answer.

If ΔLMN ~ ΔPON, what is MN?
Assoli18 [71]

Answer:

MN = 36

Step-by-step explanation:

You can find a ratio between the two triangles based on what you're given.

If LM ~ OP the ratio is 42/14 which = 3

So if MN ~ ON and ON = 12, 12(3) = 36

A right triangle has one side that measures 4 in. The angle opposite that side measures 80o. What is the length of the hypotenus
mojhsa [17]
In order to find the length of the hypotenuse, we use knowledge on trigonometric functions which would be sine and is expressed as:

sine (theta) = opposite side / hypotenuse

sine 80 = 4 / hypotenuse
Hypotenuse = 4.1 in <---- OPTION B
