Which equation represents the line with slope −2/3 that passes through (3, 0)?
The following equation [tex]y=\frac{-2x}{3}+2[/tex] represents the given line.
Linear FunctionAn equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=3x+1. Where:
a= the slope. It can be calculated for [tex]a=\frac{\Delta y}{\Delta x}[/tex].
b= the constant term that represents the y-intercept.
For solving linear equations, you should organize variables on one side of the equation and the numbers on the other side. When a number or variables change side, its signal also is changed.
For the given example: a=3 and b=1
The question gives:
the value of the slope (a) = -2/3the coordinates of a point = (3,0)Thus, you can write from the question information :
y=ax+b
0= -2/3*(3)+b
0= -2 + b
b=2
Now, you know the value of the slope and the constant term.
Therefore, the standard form for the linear equation is:

A scale factor is a number that can be used to adjust the size of any geometrical figure or object in relation to its original size. It's used to draw the enlarged or reduced shape of any given figure, as well as to calculate the missing length, area, or volume of an enlarged or reduced figure. It should be noted that the scale factor only affects the figure's size and not its shape.
A scale factor is a number or conversion factor used to adjust the size of a figure without changing its shape. It is used to enlarge or reduce the size of an object. If the dimensions of the original figure and the dimensions of the dilated (increased or lowered) figure are known, the scale factor can be determined. A rectangle, for example, has a length of 5 units and a width of 2 units. If we raise the size of this rectangle by a factor of two, the sides will become 10 and 4, respectively. As a result, we can use the scale factor to determine the dimensions of the altered figures.

work out the volume of cylinder B
Answer:
720cm³
Step-by-step explanation:
Volume of a cylinder is given by Base Area (A) x Height (h)
or V = Ah
Volume of cylinder A = 18 x 5 = 90 cm³
Base Area A = πr² where r is the radius of the base
For cylinder A, if radius = rₐ
Area = π x (rₐ)² = 18
We can see that cylinder B has twice the height of cylinder A. That means cylinder B radius is twice the radius of cylinder A
So radius of cylinder B = 2 x rₐ = 2rₐ
Base Area of Cylinder B = π x (2rₐ)² = 4π(rₐ)² = 4 x Base Area of cylinder A = 4 x 18 = 72
So while the heights are in the ration 1:2, the base areas are in the ratio 1:4 because the areas are directly proportional to the square of the radius
Hence Volume of Cylinder B = 72 x 10 = 720 cm³
Another way to look at this is that the volume of cylinder B = 8 (2 x 2 x2) times the volume of cylinder A = 8 x 90 = 720cm³

share. Express her capital gain
She sold them in 2007 for $55.10 per
as a percent, rounded to the nearest tenth of a percent.
Maria's capital gain is 55.2%.
Here, we are given that Maria purchased 1,000 shares of stock for $35.50 per share in 2003.
Thus, the total cost price of these shares = 1000 × 35.5
= $35500
In 2007, she sold all of the stocks for $55.10 per share
Thus, the total selling price of these shares = 1000 × 55.1
= $55100
Now, absolute gain = selling price - cost price
Here, Maria's absolute gain will be-
= 55100 - 35500
= 19600
Now, her percentage gain will be given by-
Gain % = absolute gain/ initial value × 100

If all the widgets from the three machines are mixed together, then the probability that a good widget will be drawn at random is 0.78 or 78%.
Probability is defined as how likely an event is to occur, or how likely it is that a proposition is true.
If machine 1 makes 3000/hour and 80% are good, then the chances of it being good is 80% also or, 2400 out of 3000.
80% of 3000 is 2400
If machine 2 makes 4000/hour and 90% are good, then the chances of it being good is 90% also or, 3600 out of 4000.
90% of 4000 is 3600
If machine 3 makes 3000/hour and 60% are good, then the chances of it being good is 60% also or, 1800 out of 3000.
60% of 3000 is 1800
Mixing together the widgets from the three machines, use the formula to calculate the probability of an event which is as follows.
Probability(Event) = Favorable Outcomes/Total Outcomes = x/n
Probability(good) = (2400 + 3600 + 1800)/(3000 + 4000 + 3000)
Probability(good) = 7800/10000
Probability(good) = 0.78 or 78%

how do you find the y-intercept from vertex form
It is found that the intercepts can be found from vertex form, if the graph is hovering above the x axis (k<0).
What is y-intercept of a function?The intersection of the graph of the function with the y-axis gives y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.
Assume that we've got: y = f(x) At y-axis, we've got x = 0, so putting it will give us the y-intercept. Thus, y-intercept of y = f(x) is y = f(0)
If a quadratic equation is written in the form y=a(x-h)² + k
therefore it is called to be in vertex form. It is called so because when you plot this equation's graph, we will see vertex point(peak point) is on (h,k)
To convert the given equation to vertex form, We will take out coefficient of x squared, and then inside the bracket, we try to make perfect square like situation.
To find the intercepts, if the graph is hovering above the x axis (k<0) then there will be no real solutions for the x intercept.

if the length of a rectangle is increased by 30 percentage and the width of the same rectangle is decreased by 30 what is the affect on the area
Answer:
The area will decrease by 9%.
Step-by-step explanation:
The area of a rectange is given by the formula below.
[tex]\boxed{\text{Area of rectangle}= \text{length}×\text{width}}[/tex]
Let the original length and width of the rectangle be L and W respectively.
Start by finding the original area:
Original dimensions
Length= L= 100%L
Width= W= 100%W
Original area= LW
Let's find the dimensions of the new rectangle in terms of L and W.
New dimensions
Length= (100% +30%)L= 130%L
Width= (100%-30%)W= 70%W
New area
[tex] = \frac{130}{100} L \times \frac{70}{100} W[/tex]
[tex] = \frac{91}{100} LW[/tex]
= 91% LW
Comparing the new area with the original area:
100% LW- 91% LW= 9% LW
∴ The area will decrease by 9%.
