Step-by-step explanation:
1.x +y = 1 Yes
2. Power of variable e is 3. So, it is not a linear equation
No.
3) Great than symbol is there. No, it is not a linear equation.
4. 2x -y = 2x + 5
2x - y - 2x = 5
-y = 5 is not a linear equation with two variable.
No.
5. No.
1) (5,14) ; (19,7)
[tex]Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{7-14}{19-5}\\\\=\dfrac{-7}{14}\\\\=\dfrac{-1}{2}[/tex]
2) (-10 , 1) ; (-10 ,4)
x- coordinate is same for both the points. So, the line is parallel to y-axis
Slope = undefined
[tex]3) (-3,-3) ; (15,13)\\\\slope=\dfrac{13-[-3]}{15-[-3]}\\\\=\dfrac{13+3}{15+3}\\\\=\dfrac{16}{18}\\\\=\dfrac{8}{9}[/tex]
[tex]4)(\dfrac{-1}{2},\dfrac{1}{7}) ; (\dfrac{-3}{2},\dfrac{2}{7})\\\\Slope=\dfrac{\dfrac{2}{7}-\dfrac{1}{7}}{\dfrac{-3}{2}+\dfrac{1}{2}}\\\\\\=\dfrac{\dfrac{1}{7}}{\dfrac{-2}{2}}\\\\\\=\dfrac{\dfrac{1}{7}}{-1}\\\\\\=\dfrac{-1}{7}[/tex]
Compare with y = mx + b ; here m is slope
1. y = -2x - 8
slope = -2
2. x = 3
Line is parallel to y-axis.
So, slope = undefined
3.2x - y = 4
2x - 4 = y
y = 2x - 4
Slope = 2
4.) 2x + y - 5 = 0
y = -2x + 5
Slope = -2

A girl can run 6 2/3 metres in one second. How long will it take her to run 100 metres?
HELP PLEASE.
Answers
Answer:
15 seconds
Step-by-step explanation:
How did i get this answer? It is apparent that the girl is capable of running 6 2/3 metres per one second and she must run 100 metres.
First, let's convert 2/3 into a decimal so that it is easier to calculate later. 2/3=0.667 (you can also just do 2 divide by 3 and will end up with the same number)
Now our numbers are 6.667 and 100. Let's divide 100 by 6.667 which estimates to 15
Answer:
It will take the girl 15 seconds to run 100 meters
Step-by-step explanation:
100÷6 2/3 is 15
reverse it to see if your right: 15×6 2/3 is 100

A dog kennel charges a daily boarding rate as shown on the graph. use the information to mark 5-8 as true or false. if false, rewrite the statement correctly. 1. The dog kennel charges $60 per day. 2. The equation y = 30x can represent the graph. 3.Third is It costs $200 to board a dog for 7 days 4. The graph will contain the coordinate (9,270) Please give me all answers to all questions or i will go into trouble
Answers
The relationship between the cost charged for the daily boarding of dogs
by the kennel is a directly proportional relationship.
The correct responses are;
1. The dog kennel charges $60 per day is; False
Correct statement; The dog kennel charges $30 per day
2. The equation y = 30·x can represent the graph; True
3. It costs $200 to board a dog for 7 days is; False
Correct statement; It costs $210 to board a dog for 7 days
4.The graph will contain the coordinate point (9, 270); True
Reasons:
Points on the graph of the given graph of the Cost to Number of days are;
(2, 60), (4, 120)
The slope of the graph is [tex]m = \dfrac{120 - 60}{4 - 2} = 30[/tex]
Equation of the graph is therefore; y - 60 = 30·(x - 2)
Which gives;
y = 30·x - 2×30 + 60 = 30·x
The equation of the graph is; y = 30·x
Therefore, the statement;
2. The equation y = 30·x can represent the graph is; TrueThe cost of the dog kennel a day is given by the value of 'y', when x = 1, as
follows;
Cost per day, y = 30 × 1 = 30
The cost per day = $30 per day
Therefore;
1. The dog kennel charges $60 per day is; FalseThe correct statement is; The dog kennel charges $30 per day
3. The statement; It costs $200 to board a dog for 7 days is; FalseThe amount it costs to board a dog for 7 days is y = $30×7 = $210
Therefore, the correct statement is; It costs $210 to board a dog for 7 days
4. When x = 9, we have; y = 30 × 9 = 270Therefore, the statement; the graph will contain the coordinate point (9, 270) is; True
