Answer:
a) -4
b) 1/4
Step-by-step explanation:
a) -4. This is because parallel lines have the same slope.
b) 1/4. This is because the product of perpendicular slopes will be -1. (This can be seen as -4 * 1/4 = -1)

write the smallest whole number that make this statement correct 1142 > >981
Answer:
982
Step-by-step explanation:
The teacher is asking for the smallest number which fits the statement. 982 is correct because it is only one more than 981.
The smallest whole number that make this statement correct 1142 > >981 is,
⇒ 982
As, 1142 > 982 > 981
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.

Consider the functions f(x) = 6x - 5 and g(x) = 6x + 3. Which statement compares the
relationship between the graphs of the two functions?
A) The graph of g(x) is the same as the graph of f(x) translated down 2 units.
B) The graph of g(x) is the same as the graph of f(x) translated up 8 units.
C) The graph of g(x) is the same as the graph of f(x) translated up 2 units.
D) The graph of g(x) is the same as the graph of f(x) translated down 8 units.
Answer:
D
Step-by-step explanation:
since we have -5 and 3, in order to translate f(g) into f(x), we subtract 8 from f(g)
The graph of g(x) is the same as the graph of f(x) translated up 8 units. Therefore, option B is the correct answer.
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Given that, f(x)= 6x-5 and g(x)= 6x+3.
When the shape is moved up by k units, then replace y with y + k.
Here, g(x)=6x-5+8
g(x)= 6x+3
The graph of g(x) is the same as the graph of f(x) translated up 8 units. Therefore, option B is the correct answer.

Using a system of equation to represent the scenario described, the cost is purchase made is $12.70
Cost per bag of chip = $1.35 Cost per bottle of soda = $0.85Cost of 5 bags of chips and 7 bottles of soda :
5(1.35) + 7(0.85) = $12.70

x=1/3 4/3*1/4=1/3
We want to see the properties used to solve the given equation.
The properties used are:
Existence of the multiplicative inverse.Associative property of the multiplication.Let's write step by step and see which property we used on each step.
We start with:
[tex]\frac{4}{3} *(\frac{3}{4} *x) = \frac{4}{3} *\frac{1}{4}[/tex]
Now we use the associative property of the multiplication (says that we can multiply in any order we want) we rewrite this to:
[tex](\frac{4}{3} *\frac{3}{4} )*x = \frac{4}{3} *\frac{1}{4}[/tex]
Now we use the existence of the multiplicative inverse, this says that for a number a, there exist a number b such that:
a*b = 1
And we have that b = 1/a.
Then we apply that to the first factor to get:
[tex](\frac{4}{3} *\frac{3}{4}) *x = \frac{4}{3} *\frac{1}{4} \\\\x = \frac{4}{3} *\frac{1}{4}[/tex]
Again, using the same but with the numerator of the first factor of the right side and the denominator of the second factor of the right side we get:
[tex]x = \frac{4}{4} *\frac{1}{3} = \frac{1}{3}[/tex]

To solve an equation, you must
which means you must perform
whatever operations are necessary so that the variable appears by itself on one side of
the equation but not on the other side.
A.use substitution
B.isolate the variable
C.check your answer
D.apply the Symmetric Property of Equality
The process of isolating the variable is the primary step involved in solving an equation.
Thus, option (B) is correct.
A) Substitution refers to the act of replacing a variable with a known value in an equation, which can be a useful strategy in some cases but is not a fundamental step in solving equations.
B) To solve an equation, it is necessary to perform operations that isolate the variable on one side of the equation and keep the other side free of the variable.
C)To verify if the obtained solution satisfies the original equation, but it is not a step required to solve the equation.
D) It states that if a = b, then b = a.
It is a property that allows us to interchange the positions of two equal expressions in an equation but is not directly related to solving equations.

The solution is, the slope of the line below is 1/2.
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
from the given graph, we get,
the line is passing through the points (-2, -3 ) and, (2, -1 )
now , we know that,
We can find the slope of a line given two points by using the following:
m = ( y2-y1)/(x2-x1)
so, substituting the values of the coordinates of the points,
we get,
m = -1 + 3 / 2 + 2
= 2 / 4
= 1/2
Hence, The solution is, the slope of the line below is 1/2.

The total amount of candy sold at Cassandra's Candy Corner can be represented by the function C(x) = 4x3 + 10x2 + 54x + 520, where x represents the number of years since the store opened. The amount of types of candy can be modeled by the linear function T(x) = 2x + 10. Which expression represents the amount of candy sold each year per type at Cassandra's Candy Corner?
2x^2 – 5x + 52
2x^2 + 5x + 52
4x^3 + 10x^2 + 52x + 510
4x^3 + 10x^2 + 56x + 530
Using polynomial division, it is found that the expression that represents the amount of candy sold each year per type at Cassandra's Candy Corner is:
[tex]2x^2 - 5x + 52[/tex]
The amount of candy sold per type is given by the following division:
[tex]\frac{C(x)}{T(x)} = \frac{4x^3 + 10x^2 + 54x + 520}{2x + 10}[/tex]
The denominator can be written as:
[tex]2x + 10 = 2(x + 5)[/tex]
At the numerator, to see if we can simplify, we verify if x = -5 is a factor:
[tex]C(-5) = 4(-5)^3 + 10(-5)^2 + 54(-5) + 520 = 0[/tex]
Since C(-5) = 0, it is a factor of the numerator, and thus, since the numerator is of the 3rd degree, it can be written as a 3 - 1 = 2nd degree polynomial multiplying x + 5:
[tex](ax^2 + bx + c)(x + 5) = 4x^3 + 10x^2 + 54x + 520[/tex]
[tex]ax^3 + (5a + b)x^2 + (5b + c)x + 5c = 4x^3 + 10x^2 + 54x + 520[/tex]
Equaling both sides:
[tex]a = 4[/tex]
[tex]b = 10 - 5a = -10[/tex]
[tex]5c = 520 \rightarrow c = 104[/tex]
Thus:
[tex]C(x) = (4x^2 - 10x + 104)(x + 5)[/tex]
And:
[tex]\frac{C(x)}{T(x)} = \frac{(4x^2 - 10x + 104)(x + 5)}{2(x + 5)} = 2x^2 - 5x + 52[/tex]
Thus, the expression is:

If f(1)=6 and f(n) = F(n - 1) + 2 then find the value of f(4).
Hi there!
[tex]\large\boxed{f(4) = 12}[/tex]
We know that:
f(1) = 6
F(n) = F(n - 1) + 2 (Meaning, the next "n" is 2 added to the previous)
We can count up to f(4) using this logic:
f(2) = F(2 - 1) + 2 = F(1) + 2 = 6 + 2 = 8
f(3) = F(2) + 2 = 8 + 2 = 10
f(4) = F(3) + 2 = 10 + 2 = 12
