Answer:
2
Step-by-step explanation:
f(x) = 3x^3 + 5x^2
f(-1)
so just substitute in the value -1 for x, and solve
f(-1) = 3(-1)^3 + 5(-1)^2
= 3 * -1 + 5 *1
= -3 + 5
= 2

a
$993 = $425s - $17.75
b
$993 = $425s + $17.75

What is the slope of a line perpendicular to Line AB given A (6,2) and B (-3,2)
Answers
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m of AB using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(- 3, 2)
m = [tex]\frac{2-2}{-3-6}[/tex] = [tex]\frac{0}{-9}[/tex] = 0
A line with a slope of zero is a horizontal line, parallel to the x- axis.
Thus a line perpendicular to AB is a vertical line parallel to the y- axis.
The slope of a vertical line is undefined

Cabletown charges $5 signup fee and a $0.50 charge per video.
Networkflicks charges a $12 signup fee and a $0.15 charge per video. How
many videos do you need to watch in a month for the two companies to cost
the same?
Answers
Given parameters:
Signup fee for Cabletown = $5
Charge per video = $0.50
Sign up fee for Networkflicks = $12
Charge per video = $0.15
Unknown:
The number of videos watched in which the cost of both months will be thesame = ?
Solution:
Let the number of videos= x
Now let us set up algebraic equations to solve this problem;
5 + 0.5x = 12 + 0.15x
Collect like terms and solve;
5 - 12 = 0.15x - 0.5x
-7 = -0.35x
x = 20
The number of videos watched will be 20 videos

What is an improper fraction?A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.
Given, a car used [tex]1\frac{2}{5}[/tex] gallons of gasoline to travel [tex]50\frac{3}{4}[/tex] Miles.
In order to solve the problem:
First, we solve covert the mixed fraction to improper fraction.
That means,
[tex]1\frac{2}{5}[/tex] = 7/5
[tex]50\frac{3}{4}[/tex] = 203/4
That means, a car used 7/5 gallons of gasoline to travel 203/4 miles.
To find the distance of car can travel on 1 gallon of gasoline:
203/4 ÷ 7/5
= 203/4 x 5/7
= [tex]36\frac{1}{4}[/tex] Miles.
Therefore, car can travel [tex]36\frac{1}{4}[/tex] Miles on 1 gallon of gasoline.

Graph XY with endpoints X(−3, 1) and Y(4,−5) after the composition. Translation: (x, y)→(x, y+2) Rotation: 90° about the origin
Answers
Answer:
X’ is (3,3) and Y’ is (-3,-4)
Step-by-step explanation:
Here, we want to get the coordinates of the point XY after translation and rotation about the origin at 90 degrees
X (-3, 1 ) and Y (4,-5)
Using the translation we have
(-3, 1 + 2) and (4, -5 + 2)
= (-3,3) and (4 , -3)
Rotation about the origin, we have
(x , y) = (y , -x)
So the new set of points will be:
(3,3) and (-3, -4)
Transformation involves changing the position of a point or line or shape.
See attachment for the graph of X"Y"
The endpoints are given as:
[tex]\mathbf{X = (-3,1)}[/tex]
[tex]\mathbf{Y = (4,-5)}[/tex]
A translation of [tex]\mathbf{(x,y) \to (x,y+2)}[/tex] means that:
[tex]\mathbf{X' = (-3,1+2)}[/tex]
[tex]\mathbf{X' = (-3,3)}[/tex]
[tex]\mathbf{Y' = (4,-5 + 2)}[/tex]
[tex]\mathbf{Y' = (4,-3)}[/tex]
A 90 degrees rotation about the origin is:
[tex]\mathbf{(x,y) \to (y, -x)}[/tex]
So, we have:
[tex]\mathbf{X" = (3, 3)}[/tex]
[tex]\mathbf{Y" = (-3, 4)}[/tex]

Line A has a slope of −3 . Line B has a slope of 4. Line C has a slope of 2
Which Line Is The Closest To Being Horizontal?
- Line A
- Line B
- Line C
- I dont Know
Answers
The line whose absolute value of the slope is least will be the slope which is close to being horizontal. Hence, line C is the answer.
An horizontal line has will have a slope value of 0. Hence, the steeper the slope, the greater the absolute value of the slope obtained. This means that a line deviates more from being horizontal as the absolute value of the slope increases.Therefore, the line with least absolute value would be the closest to being horizontal, hence, line C with an absolute value of 2.

A horizontal line is an example of a functional relationship
Each output value of a function can correspond to only one input value
Answers
Answer:
The true statemens are:
All function have (at least) a dependent variable. That is why you can write y = f(x), x is the independent variable, while y depends on x values, so y is the independent variable.
All function have and independent variable (explained above).
A horizontal line is an example of a funcitional relationship (because given a value of x, you can always tell the value of y)
The other statements are false:
The range of a function includes its domain is false.
Domain are the values that x can take and the range are the values that the function (y) can take. One is not included in the other.
A vertical line is an example of a functional relationship is false, because you can not tell the value of y for any value of x.
Each output value of a function can correspond to only one input value is false. An output can be generated by more than one value of x. The horizontal line is an example of that: the same value of y (output) corresponde to any value of x.

A: All functions have a dependent variable.
B: All functions have an independent variable.
