Step-by-step explanation:
each 20m miles takes 1g gallon.
Answer:
[tex]y=-\frac{1}{20} x + 20[/tex]
Step-by-step explanation:
The slope equation is always [tex]\frac{rise}{run}[/tex]. In this case, the gallons went down by 1- so we can call the rise -1. When it went down by 1, the miles went up by 20- so we can call the run 20. This gives us a fraction (the "m" value) to put in the slope equation [tex]y=mx+b[/tex]. To find the y intercept (the "b" value), you find out what y is when x = 0, which is given in the chart: 20.

Write an equation in standard form of the line shown.
Answers
Answer: y= -2x + 4
Hope this helps.
Explanation: You have to find your slope first in order to put it into standard form. What you have to do to find your slope is y1-y2/x2-x1 so you plug your points into that formula and have 0-2/2-1 which equals -2, so your slope is -2. You now have to put this into standard form, the easy way of doin this is y=mx+b, you have to find b so to do so you have to plug your numbers in from only one pair of points. We’ll use (2,0) so then you’ll have 0=-2(2)+b, we multiply -2*2 and get 4 and you can’t divide 4 into 0 because then you’ll have an undefined line. so your b is 4 which means your equation is -2+4x.
This question concerns bit strings of length six. These bit strings can be divided up into four types depending on their initial and terminal bit. Thus the types are: 0XXXX0, 0XXXX1, 1XXXX0, 1XXXX1. How many bit strings of length six must you select before you are sure to have at least 6 that are of the same type?
Answers
Answer:
We have to choose 21 strings to be sure we have chosen at least 6 strings of the same type.
Step-by-step explanation:
Since the string type is determined by the initial and terminal bits as understood from the question, then the value of the bits between the initial and terminal bits is of no concern to us.
Now, to be sure you have atleast 6 of the same type, we select each string five times. By doing this, we have already selected 20 strings because we have 4 strings there. Now if you choose any of the string one more time, we are certain that we must have chosen atleast 6 strings that are the same. This means we have to choose 21 strings to be sure we have chosen at least 6 strings of the same type.

x>9
Step-by-step explanation:
Remark
You have to watch this question when you divide by a minus. We should try to eliminate that possibility.
Equation
7 - 2/3 x < x - 8 Add 2/3 x to both sides
7 < x + 2/3 x - 8 Combine the like terms on the right.
7 < 1 2/3 x - 8 Add 8 to both sides
7 + 8 < 5/3 x Combine the left
15 < 5/3 x Multiply both sides by 3/5
15*3/5 < 5/3*3/5 x
9 < x
Since all the answers have the x on the left, we have to put this answer so that x is on the left. Be very careful. The big end of the arrow is towards the x. We have to make sure it stays that way.
x > 9
The answer is A

Solve the system of equations by any method.
5x+9y =16
x+2y =4
Answers
Answer:
The system of equations has one solution at (-4, 4).
Step-by-step explanation:
We are given the system of equations:
[tex]\displaystyle\left \{ {{5x+9y=16} \atop {x+2y=4}} \right.[/tex]
We can use elimination to solve this system. We need to multiply the second equation by -5 so we can cancel out our x-terms.
[tex]-5\times(x+2y=4) \rightarrow -5x - 10y = -20[/tex]
Therefore, our system now becomes:
[tex]\displaystyle\left \{ {{5x+9y=16} \atop {-5x-10y=-20}} \right.[/tex]
Now, we can add these two equations together and solve for y.
[tex]\displaystyle(5x + 9y) + (-5x - 10y) = 0 - y\\\\16 + (-20) = -4\\\\-y = -4\\\\\frac{-y}{-1}=\frac{-4}{-1}\\\\y = 4[/tex]
Now, we can substitute our value for y into one of the equations and solve for x.
[tex]x+2(4)=4\\\\x + 8 = 4\\\\x = -4[/tex]
Therefore, our final solution is (-4, 4).

A. y=-2x-4
B. y=-10x+3
C. y=3x-10
D. y=3x+10
Answers
Answer:
y=-2x-4
Step-by-step explanation:
Given that,
Slope, m = -2
It passes through the point (1,-6).
We need to find the equation of line that passes throgh the given point. It can be calculated as:
[tex]y-y_1=m(x-x_1)[/tex]
Put y₁ = -6, x₁ = 1 and m = -2
[tex]y-(-6)=(-2)(x-1)\\\\y+6=-2x+2\\\\y+2x+6-2=0\\\\y=-2x-4[/tex]
Hence, the equation of line is y=-2x-4.

An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale. Let A be the amount of the sale in dollars and C be the charge of the online auction. Explain whether the solutions A=−5 and C=1.1 are viable.
The solutions are not viable because the amount charged is not a whole number.
The solutions are viable because the amount of the sale is an integer.
The solutions are viable because the amount charged is positive.
The solutions are not viable because the amount of the sale cannot be negative
Answers
Answer:
The solutions are not viable because the amount of the sale cannot be negative
Step-by-step explanation:
We are told that;
Let A be the amount of the sale in dollars and C be the charge of the online auction
This means that both values of A and B should be non-negative integers.
Now, we are also told that An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale.
We can conclude that the solution is not viable because the amount of sale of -1.1 cannot be negative.
