A local kids play sold 8 adult tickets and 9 child tickets for a total of $205. On day two they sold only 4 adult tickets and 3

Naya [18.7K]

Answer:

The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13

Step-by-step explanation:

Let x be the cost of 1 adult ticket

Let y be the cost of 1 child ticket

Cost of 8 adult tickets = 8x

Cost of 9 child tickets = 9y

We are given that A local kids play sold 8 adult tickets and 9 child tickets for a total of $205

So, 8x+9y=205 ----- 1

Cost of 4 adult tickets = 4x

Cost of 3 child tickets = 3y

We are given that 4 adult tickets and 3 child tickets for a total of $83.

4x+3y=83 ----2

Plot 1 and 2 on graph

8x+9y=205 -- Red line

4x+3y=83 -- Blue line

Intersection point provides the solution

So, Intersection point =(11,13)

So, The price of 1 adult ticket is $ 11 and price of 1 child ticket is $13

What is the answer?????

Verdich [7]

4:7=m:42
7*6=42
so multiply 4*6 also and m=24
or 4:7=24:42

Simplify the expression. Write your answer as a complex number.

prohojiy [21]

Answer:

$15-8i$

Step-by-step explanation:

we know that

The algebraic expression is equal to

$5\sqrt{9}-\sqrt{-64}}$

Remember that

$\sqrt{9}=3$

and

$i=\sqrt{-1}$

$\sqrt{-64}=i\sqrt{64}=8i$

substitute

$5\sqrt{9}-\sqrt{-64}}=5(3)-(8i)=15-8i$

The graph represents function 1, and the equation represents function 2:

kvv77 [185]

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the slope or rate of change of the function can be:

positive

negative

zero, or

undefined

Function 1

From the function 1 graph, it is clear that the graph is a horizontal line. We must note that the horizontal line has a slope or rate of change zero. The reason is that the horizontal line can not rise vertically. i.e. y₂-y₁=0

so using the slope formula

Rate of change = m = y₂-y₁ / x₂-x₁

Taking two points (x₁, y₁) = (0, 4), (x₂, x₁) = (1, 4)

Rate of change = m = 4-4 / 1-0

Rate of change = m = 0/1

Rate of change = m = 0

Thus, the rate of change of function 1 is zero.

Function 2

We know the slope-intercept form of linear equation is

$y = mx+b$

where m is the rate of change or slope of the function and b is the y-intercept

Given the function

$y = 8x+12$

comparing with the slope-intercept form i.e. y = mx+b

Therefore, the rate of change of function 2 = m = 8

Conclusion

The rate of change of function 1 = 0

The rate of change of function 2 = 8

8 - 0 = 8

Therefore, function 2 has 8 more rate of change of function than the rate of change of function 1.
