Step 1: Define
f(x) = -3x + 17
f(x) = 2
Step 2: Solve for x
Substitute: 2 = -3x + 17Isolate x term: -15 = -3xIsolate x: 5 = xRewrite: x = 5Step 3: Check
Plug in x to verify it's a solution.
Substitute: f(2) = -3(5) + 17Multiply: f(2) = -15 + 17Add: f(2) = 2Here we see that f(2) does equal 2.
∴ x = 5 is the solution.

A))5
B))6
C))7
D))8
E))9
Answers
Answer:
A altura máxima é 5
Step-by-step explanation:
Matematicamente, a altura máxima pode ser obtida
A altura máxima é simplesmente o vértice da parábola
Começamos diferenciando a função Isso será -8x
Agora, defina -8x como 0
Isso significa que x = 0
Agora, substitua x = 0 de volta na equação temos
f (0) = -4 (0) ^ 2 + 5
f (0) = 5
A altura máxima é 5

The weight, y, in pounds, of puppies was tracked for the first 10 weeks after birth where t represents the number of weeks after birth. The linear model representing this relationship is ŷ = 2.3 + 5.73t. Collin wanted to predict the weight of a puppy at 14 weeks.
What is this an example of, and is this method a best practice for prediction? Explain your reasoning.

Answer:
This is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks.

This is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks
What is Linear model?
A linear model is a model in which the terms are added, such as has been used so far in this section, rather than multiplied, divided, or given as a non-algebraic function. Linear modeling can predict the behavior of complex systems or analyze experimental, financial, and biological data.
Linear regression is a statistical method used to create a linear model. The model describes the relationship between a dependent variable y (also called the response) as a function of one or more independent variables Xi (called the predictors).
Given data ,
Weight of the puppies = y pounds
Number of weeks after birth = t
Linear model representing the relationship between weight of puppies and time after birth in weeks is y = 2.3 + 5.73t
This is a clear idea of Linear models because the data describe a continuous response variable as a function of one or more predictor variables.
Hence , this is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks

Describe the two types of transformations that occur between function f and function g. (use words like up, down, left, right, compression or stretch in your answer.)
Answers
Answer:
g(x) = [tex]4^{(x-1)}+3[/tex]
Step-by-step explanation:
Given exponential function is,
f(x) = [tex]4^{x}[/tex]
If the given function is shifted 1 unit to the right,
h(x) = f(x - 1)
= [tex]4^{(x-1)}[/tex]
If the function 'h' is shifted 3 units up,
g(x) = h(x) + 3
= [tex]4^{(x-1)}+3[/tex]
Therefore, transformed function will be,
g(x) = [tex]4^{(x-1)}+3[/tex]

Hello, please, I need the answers!! Each year a school booster club holds a dance to raise funds. In the past, the profit of the club makes after paying for the bank and other costs has been modeled by the function p(t) = -16t^2 - 800t - 4000 where t represents the ticket price in dollars. a. What ticket price gives the maximum profit? b. What is the maximum profit? c. What ticket prices would generate a profit of $5000?
Answers
Answer:
Step-by-step explanation:
Given the profit a club makes after paying for the bank and other costs modeled by the function
p(t) = -16t^2 - 800t - 4000
t is the ticket price
The maximum profit occurs when dp/dx = 0.
dp/dx = -32t-800
since dp/dx
0 = -32t-800
32t = -800
t = -800/32
t = - 25
Hence ticket price gives the maximum profit is $-25
b) to get the maximum profit, substitute t = -25 into the modelled function
p(t) = -16t^2 - 800t - 4000
p(-25) = -16(-25)² - 800(-25)- 4000
p(-25) = -10000+20000-4000
p(-25) = 6000
Hence maximum profit is $6000
c) To get the ticket prices would generate a profit of $5000, we will substitute p(t) = 5000 and find t
p(t) = -16t^2 - 800t - 4000
5000 = -16t^2 - 800t - 4000
-16t^2 - 800t - 4000 -5000 = 0
16t^2 + 800t + 9000 = 0
Answer:
Step-by-step explanation:
Given the profit a club makes after paying for the bank and other costs modeled by the function
p(t) = -16t^2 - 800t - 4000
t is the ticket price
The maximum profit occurs when dp/dx = 0.
dp/dx = -32t-800
since dp/dx
0 = -32t-800
32t = -800
t = -800/32
t = - 25
Hence ticket price gives the maximum profit is $-25
b) to get the maximum profit, substitute t = -25 into the modelled function
p(t) = -16t^2 - 800t - 4000
p(-25) = -16(-25)² - 800(-25)- 4000
p(-25) = -10000+20000-4000
p(-25) = 6000
Hence maximum profit is $6000
c) To get the ticket prices would generate a profit of $5000, we will substitute p(t) = 5000 and find t
p(t) = -16t^2 - 800t - 4000
5000 = -16t^2 - 800t - 4000
-16t^2 - 800t - 4000 -5000 = 0
t^2 + 50t + 562.5= 0
Factorize
-50±√2500-4(562.5)/2
t = -50±√2500-2250)/2
t = -50±15.81/2
t = -65.81/2 and -34.19/2
t = -32.91 and -17.09

The equation, [tex] y = 1600 + 90x [/tex], given to us tells us much about the situation described above.
y = total pay
x = number of copies of Math is fun
1600 = y-intercept, that is the starting value or the pay he gets only if Sam sold 0 copy of Math is fun. That is, when x = 0, y = 1,600.
90 = unit rate or the change in the total pay for each copy of Math is fun that Sam sells.

A line parallel to it would have the same slope which is -5/3 so then you can plug in the points you were given and find b for the line parallel which would be 1 = -5/3(-3) + b and that would simplify into 6 = b so then you know your y intercept and you can now plug it in for the new equation y = -5/3 + 6

6/3 + (-1/6) = 6/3 - 1/6
= 6/3 - 1/6
6/3 = 2
= 2 - 1/6
2 = 6 x 2 over 6
= 6 x 2 over 6 - 1/6
= 12/6 - 1/6
apply fraction rule --> a/c - b/c = a - b over c
12/6 - 1/6 = 12 - 1 over 6

Mary bought a shirt on sale for $15.00. The sales tax was 10%. If Mary paid with a $20 bill, what was her change?
A-$4.90
B-$5.00
C-$3.50
D-$1.50
Answers
Answer:
Her change was: $3.5
Step-by-step explanation:
Mary bought a shirt on sale for $15.00.
As the sales tax was 10%.
i.e. 10/100 × 15 = $1.5
so the sales tax on $15.00 was $1.5.
Hence, the total cost Mary had to pay to buy the shirt was:
$1.5 + $1.5 = $16.5
As Mary paid with a $20 bill, therefore the change can be calculated as
20 - 16.5 = $3.5.
Therefore, her change was: $3.5
