OL is perpendicular to ON, which means that there is a 90 degree angle being created between these two line segments. So, angle LON is equal to 90 degrees. Because LON is a 90 degree angle and we have two angles within it, those two angles are complimentary. We can add LOM and MON together and they will equal 90 degrees.

3x - 15 + 5x - 23 = 90

8x - 38 = 90

8x = 128

x = 16 degrees

Angle MON = 5x - 23

5(16) - 23 = 57 degrees

Angle MON = 57 degrees

Hope this helps!! :)

Answer:

LOM 3x-15 Lets say x is 15 = 3x

3x= 45-15 = 30

MON, therefore 5x-23= 75-23=52

It is a right angle we want 8 more divided by 3+5=8/8

Lets say x is now 16

LOM 3x= 48 48-15 = 33

MON 5x -23= 80 = 80-23= 57

Both angles add up to 90 degree making the right angle.

Phil is riding his bike. He rides 46 miles in 4 hours, 57.5 miles in 5 hours, and 69 miles in 6 hours. Find the constant of prop

FromTheMoon [43]

Answer:

The constant of proportionality k = 11.5.

The equation will be: $\mathbf{y=11.5(x)}$

Step-by-step explanation:

If x represents number of hours than y represents miles

We are given:

x y

4 46

5 57.5

6 69

The constant of proportionality can be found using formula: $k=\frac{y}{x}$

Putting values and finding k

x y k ( $k=\frac{y}{x}$ )

4 46 11.5

5 57.5 11.5

6 69 11.5

So, the constant of proportionality k = 11.5

Now, The equation will be:

$k=\frac{y}{x}\\or \\y=kx\\Put \ k=11.5\\y=11.5(x)$

So, the equation will be: $\mathbf{y=11.5(x)}$

Which ordered pairs are solutions to the inequality y - 3x < -8?

7nadin3 [17]

Answer:

Option B,C and E are solution to given inequality $y - 3x < -8$

Step-by-step explanation:

We need to check which ordered pairs from given options satisfy the inequality $y - 3x < -8$

Ordered pairs are solutions to inequality if they satisfy the inequality

Checking each options by pitting values of x and y in given inequality

A ) (1, -5)

$-5-3(1)$

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

B) (-3, - 2)

$-2-3(-3) < -8\\-2-9$

So, this ordered pair is solution of inequality as it satisfies the inequality.

C) (0, -9)

$-9-3(0)$

So, this ordered pair is solution of inequality as it satisfies the inequality.

D) (2, -1)

$-1-3(2)$

So, this ordered pair is not the solution of inequality as it doesn't satisfy the inequality.

E) (5, 4)

$4-3(5)$

So, this ordered pair is solution of inequality as it satisfies the inequality.

So, Option B,C and E are solution to given inequality $y - 3x < -8$
