Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)
Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)
Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.
(Hard) A composite number n is called a Carmichael number bn−1 ≡ 1 (mod n) for every number b such ... Base case: When n = 2 the formula a + c ≡ b + d (mod m) was already given. ... The sequence goes 1, 3, 7, 15, 31,... guess that it is equal to 2n+1 − 1. ... Prove (now using induction on n) that fm|fmn for all n ≥ 1.
Inequalities are used to show the relationship between unequal expressions.
The inequalities that represent the maximum weights are:
- <em>2 axles - </em><em>.</em>
- <em>3 axles - </em><em>.</em>
- <em>4 axles - </em><em>.</em>
<em />
Let the maximum weight be represented with x
In inequality, maximum means less than or equal to i.e.
<u>(a) 2 axles</u>
The maximum weight, here is 40000.
So, the inequality is:
<u>(b) 3 axles</u>
The maximum weight, here is 60000.
So, the inequality is:
<u>(c) 4 axles</u>
The maximum weight, here is 80000.
So, the inequality is:

he change 3/4 instead of 5/7
Answer:
On the first one, multiply 6 by 3 (18) and subtract from 27 = $11
Step-by-step explanation:
$11 divided by three
About $3.66 Per day. I don't know how to do those graphs you doin but that's the answer to the question itself. Hope I helped?
The second one:
Divide 77 by 7 days (11)
Then subtract 4 from that (which gives you 7) because you need to know how much water is used on the flowers, not the shrubs. So, the answer should be 7. Correct me if I'm wrong, people.
