The table shows input and output values of a function given a rule. Which function represents the rule?
Input: x, a number; Output: y, 3 less than 2 times x
Input,x -2 -1 0 1 2
Output,y -7 -5 -3 -1 1
A. Y= 2x - 3
B. Y= -2x + 3
C. Y= -3x - 2
D. Y= 3x + 2
Answers
Because 2 times x is 2x, and 3 less than that is -3. So we can write them into 2x - 3 = Y
The correct function for the given rule will be;
⇒ Y = 2x - 3
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Input: x, a number
Output: y, 3 less than 2 times x
And,
Input, x -2 -1 0 1 2
Output, y -7 -5 -3 -1 1
Now,
Since, For the function we have;
Input: x, a number
Output: y, 3 less than 2 times x
So, We get;
The function is,
⇒ Y = 2x - 3
And, Here given that;
Input, x -2 -1 0 1 2
Output, y -7 -5 -3 -1 1
Substitute all the values and check it as;
⇒ Y = 2x - 3
Put Y = - 7 , x = - 2
⇒ - 7 = 2 × - 2 - 3
⇒ - 7 = - 4 - 3
⇒ - 7 = - 7
Thus, The value of function is,
⇒ Y = 2x - 3

Factor out the coefficient of the variable. 1/3y-3/2
Answers
Answer:
[tex]\frac{1}{3} \left(y-\frac{9}{2} \right)\\[/tex]
Step-by-step explanation:
Remeber that factoring is the same thing as applying the distributive property in reverse. Take the example 3(y + 4). To distribute, we multiply each term by the factor 3 to get the expression 3y + 12. To factor out the 3, we do the opposite, dividing the 3y and the 12 by 3, and pulling the 3 out front to again get 3(y + 4).
Here, we'd like to factor out 1/3 from the expression [tex]\frac{1}{3}y-\frac{3}{2}[/tex]. Dividing each term by 1/3 (the same thing as multiplying each term by 3), we get the expression [tex]y-\frac{9}{2}[/tex]. Remember though, the 1/3 never went away, we just pulled it out of the expression, so our full answer is
[tex]\frac{1}{3} \left(y-\frac{9}{2} \right)\\[/tex]
Diana's parents keep a chart on the wall where they mark how much Diana grows each year. When Diana was 15, she grew 5/6 of an inch and when she was 16, she grew 1/3 of an inch. In total, how much did Diana grow in during those two years?
a. 1 and 1/2
b. 1 and 1/6
c. 1/2
d. 3/6
Answers
Answer:
d?
Step-by-step explanation:
To explain:
5/6 and 1/3 are different denominators, so we need to multiply 1/3 by two.
1/3*2=2/6
5/6+2/6=7/6
7/6 is another way of saying 1 and 1/6!
Hope that helps:)

1. What is the expanded form of the expression 3.6(t + 5)?
2. If you know the value of t, would the evaluated expression be different if you added the known value of t and 5 and then multiplied by 3.6? Explain.
Answers
Answer:
Step-by-step explanation:
1) The expanded form of 3.6(t + 5) is 3.6t + 18.
The expression 3.6(t + 5) is equivalent to 3.6t + 18 and yes, the given value will be different for different values of [t].
What is equation modelling? What is a mathematical equation and expression?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.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the expression as -
3.6(t + 5)
We have the following expression -
3.6(t + 5)
3.6t + (3.6 x 5)
3.6t + 18
YES, the given value will be different for different values of [t].
Therefore, the expression 3.6(t + 5) is equivalent to 3.6t + 18 and yes, the given value will be different for different values of [t].

Answers
Answer:
The answer is C. a = -4,000 m
Step-by-step explanation:
If you subtracted 31,000 from 35,000, you would get 4,000 in a minute. Do the same for the rest, you would also get 4,000 m in a minute, so the answer would be a = -4,000 m
Answer:
A= -4,000m + 39,000
Step-by-step explanation:
If your doing the calculation it would be right
Given: -4,000m + 39,000
-4,000(1) + 39,000 = 35,000ft
-4,000(2) + 39,000 = 31,000ft
I don't know how to explain, but ig if you have the negative 4000, and you mutiply and add 39,000 it would decrease the ft
