The solution point is (4,2).

Step-by-step explanation:

Equation of straight line passing through the points (0,0) and (4,2) is given by

⇒ 2y = x ............ (1)

And the other straight line is y = - x + 6 .............. (2)

Now, solving equations (1) and (2) we get, y = - 2y + 6

⇒ 3y = 6

⇒ y = 2

And from equation (1) we get, x = 2y = 4

Therefore, the solution point is (4,2). (Answer)

An arithmetic sequence is defined by the general term tn = 19 - (n - 1)18, where n ∈N and n ≥ 1. What is the recursive formula o
vovikov84 [41]
t_n=19-18(n-1)
t_{n-1}=19-18(n-2)
\implies t_n-t_{n-1}=-18(n-1)+18(n-2)
\implies t_n=t_{n-1}-18n+18+18n-36
\implies t_n=t_{n-1}-18

So the recursive formula is

\begin{cases}t_1=19\\t_n=t_{n-1}-18&\text{for }n>1\end{cases}

What is the rate of change for the linear function f(x)=-2x-5 over any interval?
julia-pushkina [17]

To solve this problem you must apply the proccedure shown below:

1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.

2. You have the equation of the line has the following form:

y=mx+b

Where m is the slope and b is the y-intercept.

3. Then, you have that the slope of the function f(x)=-2x-5 is:

m=-2

Therefore, the answer is: -2

Henry know that the circumference of a circle is 18 pie inches. What is the area of the circle?
Leto [7]

Answer:

B: 81π inches

Step-by-step explanation:

The formula for the circumference of a circle is C = πd and the formula for the area of a circle is A = πr²

  • The formula for the circumference of a circle can also be written as C = 2πr since the diameter is equal to double the radius (d = 2r)
  • So we need to solve for r since that is the variable we are missing in order to solve for the area

Plugging in our known values to the circumference formula we have:

  • 18π = 2πr
  • Then dividing both sides by 2π we have 9 = r

Now that we have solved for the radius, we can plug in this value to the area formula:

  • A = π(9)² = 81π in

The student council is selling cupcakes at the school play. ​The cost to ​make the cupcakes is a fixed $75 plus $0.17 per cupcak
dedylja [7]

Answer:

C = 75 + 0.17x and R = 2x

2x - (75 + 0.17x) > 0

x ≥ 41

Step-by-step explanation:

The cost to make the cupcakes is a fixed $75 plus $0.17 per cupcakes made and the selling price of each cupcake is $2.00.

Part A: Now, the equation for the cost, C, for making x cupcakes is  

C = 75 + 0.17x ......... (1)

Again the equation for the revenue, R, from selling x cupcakes is

R = 2x ............ (2)

Part B: So, the inequality that could be solved to find the number of cupcakes, x, that must be made and sold to make a profit is  

R - C > 0

2x - (75 + 0.17x) > 0 ......... (3)

Part C: Solving inequality (3) we get

(2 - 0.17)x > 75

⇒ x > 40.98

⇒ x ≥ 41 {Since, x can not be a fraction}
