Answer:
the answer of this question is number D. 2
HOPE IT HELPED YOU !!!
Answer:
D. x = 2
Step-by-step explanation:
Rearrange so that the variable is on one side and the rest are on the other
0.6x = 2.4 - 1.2
0.6x = 1.2
To make x on its own, you divide 0.6 from both sides
x = 2

Write a quadratic function in standard form with zeros 1 and -10
Answer:
f(x)=x^2+9x-10
Step-by-step explanation:
Standard Form of Quadratic Function
The standard form of a quadratic function is:
[tex]f(x)=ax^2+bx+c[/tex]
where a,b, and c are constants.
The factored form of a quadratic equation is:
[tex]f(x)=a(x-\alpha)(x-\beta)[/tex]
Where [tex]\alpha[/tex] and [tex]\beta[/tex] are the roots or zeros of f, and a is constant.
We know the zeros of the function are 1 and -10. The function is:
[tex]f(x)=a(x-1)(x-(-10))[/tex]
[tex]f(x)=a(x-1)(x+10)[/tex]
Operating:
[tex]f(x)=a(x^2+10x-x-10)[/tex]
Joining like terms:
[tex]f(x)=a(x^2+9x-10)[/tex]
Since we are not given any more restrictions, we can choose the value of a=1, thus. the required function is:
[tex]\boxed{f(x)=x^2+9x-10}[/tex]
Eva, Josh, and David gather and shell pecans for their mother. Eva gathers 2 1/2 pounds of pecans, Josh collects 3.25 pounds, and David harvests 4 3/8 pounds. If they place all the pecans in one basket and each shells the same amount of pecans, how many pounds would each person shell? Group of answer choices
Answer:
3.375 pounds.
Step-by-step explanation:
Total number of pounds of pecans =
2 1/2 pounds of pecans + 4 3/8 pounds + 3.25 pounds
= (6.875 + 3.25) pounds
= 10.125 pounds.
The total number of person = 3 person.
Therefore, the number of pounds each person would shell =
10.125 pounds/3
= 3.375 pounds

After 4 minutes of reading, Aaron was on page 14 of his book. After 8 minutes he was on page 20. Which equation models the page number, y, in terms of minutes x?
Group of answer choices
y = 8x + 1.5
y = 1.5x + 8
y = −1.5x + 8
y = –8x + 1.5
Answer:
The answer would be (B) y = 1.5x + 8
Step-by-step explanation:
The equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Aaron who is reading a book. After 4 minutes of reading, Aaron was on page 14 of his book and after 8 minutes he was on page 20.
Now -
(x) represents the number of minutes and (y) is the number of pages.
At x = 4, y = 14
At x = 8, y = 20
The slope of the line will be -
m = (20 - 14)/(8 - 4)
m = 6/4
m = 3/2
The general equation can be written as -
y = 3x/2 + c
20 = 3/2 x 8 + c
20 = 12 + c
c = 8
Now, we can write the equation as -
y = 1.5x + 8
Therefore, the equation that models the number of pages (y) and number of minutes (x) is y = 1.5x + 8.

Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.
According to a study, for every 50C increase in rental price, the average business can expect to lose 4 rentals a day.
Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50 price increases.
b(x)= x + x+ [
Answer:
b(x) = -2X² + 19X + 114
Step-by-step explanation:
b(x) = total revenue generated per day
total revenue formula ⇒ b(x) = price x quantity
price = $3 current price + 0.5X price increase = 3 + 0.5X
quantity = 38 current quantity sold - 4 books per X = 38 - 4X
b(x) = (3 + 0.5X) · (38 - 4X)
b(x) = 114 -12X + 19X - 2X²
b(x) = -2X² + 19X + 114
