Answer:

x=14

Step-by-step explanation:

28/16 = 1.75

1.75 is the constant of proportionality

63/1.75 = 36

therefore, 2x+8 should be equal to 36

2x+8 = 36    >> subtract 8 from both sides

2x = 28        >> divide both side by 2 to get x alone

x = 14

In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of m?
katen-ka-za [31]
<span>The table to represent a linear function with a rate of change of +5
</span>
so, m = 13 + 5 = 18

The correct answer is option 3 ⇒ <span>m = 18
</span>
========================================
another solution :
The table represents a linear function
the general equation of the linear function is ⇒ y = ax+b
where a is the slope and b is constant
By using the first and the third points from table to find the equation of the linear function
at x = 3  ⇒ y = 13   and   at x = 5 ⇒ y = 23
∴ 13 = 3a+b → (1)

23 = 5a+b → (2)
solve (1) and (2) to find a and b
So,  a = 5  and b = -2
∴ y = 5x - 2

After that by substitution with x = 4 int the equation of y
∴ y = 5*4-2 = 18

∴ m = 18

Given: m∠AOC = 120°, m∠BOD = 150°. Find: m∠BOC.
Molodets [167]

angleBOC = 270°

All 3 angles meet at O thus

angleBOC = angle AOC + angle BOD = 120° + 150° = 270°
