On a graph, y 3x 3 would be a line that is 3 units below the line y = 3x. It would have the same slope but lower y-intercept.
To graph y 3x 3, we can first graph y = 3x. To do this, we can pick any two points along the line and plot them. For example, if we choose (0,0) and (1,3), the line would look like this:
(0,0) -------------------------- (1,3)
Now, to graph y 3x 3, we want to move the line 3 units down. Therefore, the new points that we plot should be (0,-3) and (1,0). The graph should look like this:
(0,-3) -------------------------- (1,0)
This line is 3 units below the line y = 3x. It has the same slope, but a lower y-intercept.

Given f(x) = −x² – 8x, find ƒ(−3)
Answer:
15
Step-by-step explanation:
To find f(-3), substitute x with (-3)
f(x) = -x² - 8x
f(-3) = - (-3)² - 8*(-3)
= - (9) + 24
= - 9 + 24
= 15
Answer:
15
Step-by-step explanation:
f ( x ) = - x² - 8x
Accordingly, to find the value of f ( -3 ) you have to replace x with ( - 3 ).
f ( -3 ) = - (-3)² - 8 × -3
f ( -3 ) = - 9 + 24
f ( -3 ) = 15

The radius of a circle is 6 centimeters. What is the circle's circumference?
Answer:
37.7 cm
Step-by-step explanation:
C=2πr=2·π·6≈37.69911
Answer:
37.68 cm.
Step-by-step explanation:
The formula for circumference of a circle is: πd (diameter)
The radius of this circle is 6 centimeters.
To find the diameter, multiply the radius by 2.
6 × 2 = 12.
12 is the diameter.
Lastly, multiply the diameter by pi.
**3.14 IS A SUBSTITUTE FOR PI**
3.14 = 37.68.
Therefore, the circumference of this circle is 37.68 cm.

Verbal expressions are often used to explain math problems or to pose questions.Algebraic expressions, on the other hand, use symbols and operations to express mathematical concepts. Symbols such as +, -, x, and / can be used to represent addition, subtraction, multiplication and division, respectively. Algebraic expressions are also used to simplify equations and can be used to solve math problems. For example, an algebraic expression such as "2x + 3y" can represent the sum of two numbers multiplied by two and three, respectively.The main difference between verbal expressions and algebraic expressions is that verbal expressions use words to explain a mathematical concept while algebraic expressions use symbols and operations.

Answer:
[tex]-3/\sqrt{58}[/tex]
Step-by-step explanation:
tan = opposite / adjacent
opposite side is the y-coordinate of a point on the terminal side
adjacent side is the x-coordinate of a point on the terminal side
if the terminal side is in the second quadrant (the top-left quadrant), a coordinate on the terminal side would have a negative x-coordinate and a positive y-coordinate
This being the case:
the opposite side (y) would be -3 and the adjacent side (x) would be 7
using the Pythagorean theorem:
[tex]a^2+b^2=c^2[/tex]
[tex]7^2+(-3)^2=c^2[/tex]
The hypotenuse is c, so it equals [tex]\sqrt{58}[/tex]
sin = opposite / hypotenuse
so sin(theta) = [tex]-3/\sqrt{58}[/tex]

The slope of the line is given by the equation slope m = 3/2
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , let the first point be P = P ( 0 , 1 )
Let the second point be Q = Q ( 2 , 4 )
Now , the slope of the line between the two points is
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 4 - 1 ) / ( 2 - 0 )
On simplifying the equation , we get
Slope m = ( 3 / 2 )
Therefore , the value of m is 3/2
Hence , the slope of the line is 3/2

The height of the apple trees in an orchard are normally distributed with a mean of 12.5 feet and a standard deviation of 1.2 feet what percentage of the apple trees are taller than 14.9 ft
Answer:
2.275%
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score = 14.9 ft
μ is the population mean = 12.5 ft
σ is the population standard deviation = 1.2 ft
We are to find the percentage of the apple trees are taller than 14.9 ft,
This means x > 14.9, x greater than 14.9
Hence,
z = (14.9 - 12.5)/1.2
z = 2
Probability value from Z-Table:
P(x<14.9) = 0.97725
P(x>14.9) = 1 - P(x<14.9) = 0.02275
Converting to Percentage
= 0.02275 × 100
= 2.275%
Therefore, the percentage of the apple trees that are taller than 14.9 ft is 2.275%

and solve an equation which can be used to determine j, how much each
bottle of juice costs?
The linear equation for jj is ($7.46 - $2.66) / 5 and the cost of each bottle of juice is $0.96.
What in mathematics is a linear equation?
A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.
Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.
The first step to take in order to determine jj, is to determine the total cost of the 5-pack of juice bottles.
Cost of the 5-pack of juice bottles = Total cost before tax - cost of the bag of oranges
Cost of the 5-pack of juice bottles = $7.46 - $2.66 = $4.80
The second step is to determine the cost of each bottle of juice
The cost of each bottle of juice = Cost of the 5-pack of juice bottles / total number of bottles
$4.80 / 5
= $0.96

A, B ≥ 0
For the provide inquilty problem,
a) The feasible region lies in between the following equations,
On or below the line y = 5On or to the left of the line x = 6On or above the y-axis i.e, y = 0On or to the right of the x-axis, x=0 On the linear line 2x + 2y = 14b) The extreme points of feasible region are (2,5) , (6,1) ,(0,0),(6,0),(0,5).
Let consider, x = A and y = B, this changes your inequalities and equations as follows: Maximize x + 2y, such that:
x ≤ 6
y ≤ 5
2x + 2y = 14
x,y ≥ 0
We use graphical method, for getting the solution of problem. So, first change the Inequalities into equality equations.
x = 6y = 52x + 2y = 14x = 0y = 0we would then find the region of feasibility by looking at the areas on the graph that satisfy the inequalities and equations,
x ≤ 6
y ≤ 5
2x + 2y = 14 (this is an equation)
x ≥0
y ≥ 0
a) The graph will look like as present above : we can see that the feasible region is the area on the graph that is:
on or below the line y = 5
on or to the left of the line x = 6
on or above the line y-axis , y = 0
on or to the right of the x-axis, x = 0
on the line 2x + 2y = 14
This says is that your solution has to be on the line of 2x + 2y = 14, have an x-coordinate that is greater than or equal to 0 and less than or equal to 5 and have a y-coordinate that is greater than or equal to 0 and less than or equal to 5. The maximum or minimum value should be at the corner points of the feasible region.
b) The corner points would be at (x,y) = (2,5) and (x,y) = (6,1). Also, plotted some other points on the line just to show the max/min value of function on the corner points of the feasible region.
(2,5) = 12
(4,3)= 10
(3,4) = 11
(6,1) = 8
the maximum solution is at the coordinate of (2,5) and all of your constraints have to be satisfied at the this point. The solution is that the maximum value is when x = 2 and y = 5, that is one of the corner points of the feasible region.
