Final answer:
The answer explains the graph of y=x+1.5, a direct relationship with a positive slope, and the graphical representation of the dependence of y on x.
Explanation:
Mathematics: The graph represents the rule y=x+1.5, showing a straight line with a positive slope where the y-intercept is 1.5. As x-values increase, the line gradually rises on the graph.
Direct Relationship: The line's slope remains the same, indicating a direct relationship between x and y.
Slope and Graphical Representation: By connecting points like (1,5), (2,10), (3,7), and (4,14), the dependence of y on x can be graphically illustrated.

find the distance between the two points 5,6 and 0,-6. Show your work
Answer:
The distance between two points is √169 or 13.
Step-by-step explanation:
In the question we need to find the distance between two points 5,6 and 0,-6 given.
Distance between two points can be found using the formula:
[tex]d(P1,P2) = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}[/tex]
Putting the given points in the formula we get,
x₂ = 0, x₁ = 5, y₂= -6, y₁= 6
[tex]=\sqrt{(0-(5))^2 + (-6-(6))^2} \\=\sqrt{(0-5)^2 + (-6-6)^2}\\=\sqrt{(-5)^2 + (-12)^2}\\=\sqrt{25 + 144}\\=\sqrt{169}\\=13[/tex]
So, the distance between two points is √169 or 13.
A toy manufacturer uses 90 pints of plastic to make 600 action figures. If they use 810 pints of plastic in an 8 hour shift, how many action figures are made per hour?
A) 600 action figures per hour
B) 625 action figures per hour
C) 650 action figures per hour
D) 675 action figures per hour
Answer:675(d)
Step-by-step explanation:so you take ratio
90-600
810-x
x=5400
After you divide 5400 by 8 hours and you get 675- to get how much figures he get for one hour
Final answer:
To find out how many action figures are made per hour, divide the amount of plastic used per hour by the amount of plastic used to make one action figure. In this case, 113 action figures are made per hour.
Explanation:
To find out how many action figures are made per hour, we need to determine the amount of plastic used per hour and then divide it by the amount of plastic used to make one action figure.
First, we need to find the amount of plastic used per hour. Since 810 pints of plastic are used in an 8-hour shift, we divide 810 by 8, which gives us 101.25 pints of plastic per hour.
Next, we need to determine how many action figures can be made with 101.25 pints of plastic. We divide 101.25 by 90 (the amount of plastic used to make 600 action figures), which gives us 1.125 action figures per pint of plastic.
Finally, we multiply 1.125 by 101.25 to find the number of action figures made per hour. This gives us 113.4375 action figures per hour. Since we can't have a fraction of an action figure, we round this to the nearest whole number, which is 113 action figures per hour.

A rectangular prism has a height of 12 centimeters and a square base with sides measuring 5 centimeters. A pyramid with the same base and half the height of the prism is placed inside the prism, as shown in the figure.
The volume of the space outside the pyramid but inside the prism is
cubic centimeters.
Answer:
250 cubic cm
Step-by-step explanation:
First step is to measure the volume of the rectangular prism... which is easy... it's the width * length * height. Since we have a square base, the width and length are the same: 5 cm. The volume is then: 5 * 5* 12 = 300 cubic cm.
The volume of a pyramid is obtained by the following formula:
V = (1/3) * base_area * height
We have the base area (5 * 5 = 25) and we have the height: 6 cm (half of 12 cm).
So, the volume of the pyramid is:
V = (1/3) * 25 * 6 = (1/3) * 150 = 50 cubic cm
The volume inside the prism but OUTSIDE the pyramid is then the volume of the prism (300 cubic cm) - the volume of the pyramid (50 cubic cm), so 250 cubic cm.

identify the type of variation represented by y=3/x
Answer:
Inverse variation
Step-by-step explanation:
Given equation is [tex]y=\frac{3}{x}[/tex].
Now we need to identify the type of variation represented by [tex]y=\frac{3}{x}[/tex].
We know that there are two type of variations direct and inverse.
If y and x are in direct variation then we write equation as [tex]y=kx[/tex].
where k is the constant of variation.
If y and x are in inverse variation then we write equation as [tex]y=\frac{k}{x}[/tex].
Given equation [tex]y=\frac{3}{x}[/tex] looks similar to [tex]y=\frac{k}{x}[/tex].
So that means finala answer is "Inverse variation".

What is the inverse of the following function?
y= 2^x + 3
Answer: [tex]y=log_2(x-3)[/tex]
Step-by-step explanation:
To obtain the inverse of the function [tex]y= 2^x + 3[/tex], you need to solve the equation for the variable "x":
[tex]y= 2^x + 3\\\\y-3=2^x\\\\log_2(y-3)=log_2(2^x)\\\\x=log_2(y-3)[/tex]
Now you need to exchange the variable "x" with the variable "y". Then:
[tex]y=log_2(x-3)[/tex]
Finally, you get that the inverse of the function [tex]y= 2^x + 3[/tex] is:
[tex]y=log_2(x-3)[/tex]

17) A marble paperweight shaped like a pyramid weighs 0.15 lbs. How much does a similarly shaped
marble paperweight weigh if each dimension is three times as large?
Answer:
The weight of the larger marble paperweight is 4.05 lb
Step-by-step explanation:
we know that
If two solids are similar, then the ratio of its weights (or volumes) is equal to the scale factor elevated to the cube
Remember that the scale factor is the ratio between corresponding sides
Let
z ------> the scale factor
x -----> the weight of the larger marble paperweight
y -----> the weight of the original marble paperweight
[tex]z^{3} =\frac{x}{y}[/tex]
In this problem we have
[tex]z=3[/tex]
[tex]y=0.15\ lb[/tex]
substitute and solve for x
[tex]3^{3} =\frac{x}{0.15}[/tex]
[tex]x=(27)(0.15)=4.05\ lb[/tex]
therefore
The weight of the larger marble paperweight is 4.05 lb

What is the linear function equation represented by the graph?
Answer:
y = (3/5)x + 3
Step-by-step explanation:
You can see immediately that the y-intercept is (0, 3).
As we go right from the point (-5, 0) to the point (0, 3), x increases by 5 and y increases by 3. Thus, the slope of this line is m = rise / run = 3/5.
Starting with the generic y = mx + b, we get y = (3/5)x + 3.
Answer:
Y=3/2x-3
Step-by-step explanation:
3/2 is the slope. Remember, rise/run. so the rise is 3 and the run is 2. so up three since its positive and right 2 cuz its positive. and the -3 is the y inercept. hope this helps love :)
