Hello :
by : <span>an = an-1 + 9. 
n= 2 : a2 =a1+9
         a2 = -12+9 = -3
n=3 : a3 = a2 +9 
        a3 = -3+9 = 6
n = 4 : a4 = a3 +9

Use the table below. Do x and y have a proportional relationship? Explain.
nydimaria [60]

Answer:

No

Step-by-step explanation:

For x and y to have a proportional relationship, then

the ratio of k = \frac{y}{x} must be equal for all points

(2, 5) → k = \frac{5}{2} = 2.5

(3, 7.5) → k = \frac{7.5}{3} = 2.5

(5, 12.5) → k = \frac{12.5}{5} = 2.5

(18, 8) → k = \frac{18}{8} = 2.25 ≠ 2.5

k is not equal for all values , hence no proportional relationship exists

WARRIOR [948]

Answer:

-------------------Heya Kjowanpreet!--------------

\large{ \tt{ \star\: S \: O \: L \: U \: T \: I \: O \: N : }}

GiveN :

  • Sides of the triangle : 3 in , 5 in and 4 ft

To FinD :

  • Area of the provided right angled triangle

FormulA :

  • Area of right angled triangle = 1/2 b × p where b = base & p = perpendicular. Here , Perpendicular = 3 in and base = 4 in

SolvinG :

\large{ \boxed{ \bf{Area \: of \:right \: angled \: triangle : \frac{1}{2} b \times p  }}}

\longrightarrow{  \tt{} \frac{1}{2}  \times 3 \times 4}

\longrightarrow{ \boxed{ \tt{6 \: in ^{2} }}}

  • Yay ! Finally , We solved. Our final answer is 6 square inches.

Write the slope-intercept form of the equation of the line.<br> slope = 0, y - int=1
saveliy_v [14]

Answer:

y= 1

Step-by-step explanation:

This is because there will be no increase or decrease of x since we have no slope to take us there so it will remain constant at the y value

Hope This Helps :)
