The cost of mailing a first-class letter is $0.46 for the first ounce and $0.20 for each additional ounce or portion of an ounce. Y is the total cost for mailing a letter that weighs x ounces. What is the cost of mailing a first class letter weighing 2.5 ounces based on the guidelines given in the previous problem?
Answer:linear function
Step-by-step explanation:
The cost of mailing a first class letter weighing 2.5 ounces is $0.96,
What are linear equation?A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now given that,
cost of mailing a first-class letter for the first ounce = $0.46
cost of additional ounce or portion of an ounce = $0.20
Since,the weight of letter is x ounces
cost of mailing a first-class letter = $0.2x
Now,Y is the total cost for mailing a letter
Y = 0.46 + 0.2x
Therefore, the cost of mailing a first class letter weighing 2.5 ounces
Y = 0.46 + 0.2*2.5
⇒ Y = 0.46 + 0.5
Y = $0.96
Thus,The cost of mailing a first class letter weighing 2.5 ounces is $0.96

Find the maximum value of the function
f(x) = –22 – 15.9x – 57 to the nearest hundredth.
The graph of F(x), shown below, resembles the graph of G(x) = x^2?, but it has
been changed somewhat. Which of the following could be the equation of
F(x)?
Answer:
D
Step-by-step explanation:
Slope is negative, derivative of x shows that -3 is the maximum in C/D but C is not negative
The function F(x) = -3(x + 3)^2 + 3.
The correct option is (D).
What is a Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). A variable y is said to be a function of the independent variable x if there is a relationship between them.
As per the given data:
We are given the equation of the functions G(x) and we have to find out the equation of the function F(x).
Equation of G(x) = x^2
For a left shift of 3 units x → x + 3.
⇒ y = (x + 3)^2
For a change in concavity, if the curve, multiply by -3.
⇒ y = -3(x + 3)^2
For an up shift of 3 units y → y -3.
⇒ y - 3 = -3(x + 3)^2
The function F(x) comes out to be:
F(x) = -3(x + 3)^2 + 3
Hence, The function F(x) = -3(x + 3)^2 + 3.

Evaluate the expression n x p + p n=3 p=6
Answer:
24
Step-by-step explanation:
Since we know what the variables are, we can substitute them. So, you’ll get 3 x 6 + 6. Next, do 3 x 6, which equals 18. Then add the 6, which finally equals 24.

2 ( 2x - 7 ) = - 34
Answer:
x = -5
Step-by-step explanation:
Original equation:
2(2x - 7) = -34
Use distributive property
2 · 2x = 4x
2 · (-7) = -14
Plug these values back into the equation
4x - 14 = -34
Add 14 to both sides
4x = -20
Divide both sides by 4
x = -5
Hope this helps :)

Please explain. Thanks so much!
a²b is the same thing as ba²
b and a are two separate variables lets pretend a is 2 and b is 3

3 * 2² = 3 * 4 = 12
this is the commutative property of multiplication

Answer:
m<C = 66°
Step-by-step explanation:
Perpendicular bisector, AB divides angle CAD into two equal parts. Therefore:
(5x + 9)° = (7x + 3)°
Solve for x
5x + 9 = 7x + 3
Collect like terms
5x - 7x = -9 + 3
-2x = -6
Divide both sides by -2
x = 3
✔️m<C + m<CBA + m<BAC = 180° (sum of triangle)
m<C + 90° + (7x + 3)° = 180 (substitution)
Plug in the value of x and solve
m<C + 90 + 7(3) + 3 = 180
m<C + 90 + 21 + 3 = 180
m<C + 114 = 180
m<C = 180 - 114 (Subtraction property of equality)
m<C = 66°

Which sign makes this number sentence true? 560 – 39 [ ] 275 x 2
Answer:
560-39<275*2
Step-by-step explanation:
560-39=521
275*2=550
521<550
Answer:
<
Step-by-step explanation:
560 - 39 [ ] 275 × 2
We can evaluate the expressions first before deciding which sign to use.
521 [ ] 550
As you can see, the left side of the equation is smaller than the right side of the equation, so the sign should be <.
521 < 550
521 is smaller than 550.
Other signs and meanings:
> means the left side is bigger than the right side of the equation.
≤ means the left side is smaller than or equal to the right side of the equation.
≥ means the left side is bigger than or equal to the right side of the equation.
