Answer:
y = 3x - 2
Step-by-step explanation:
The number beside the x is the slope. The number at the end of the equation is the y-intercept.
All the answers are in this form:
y = mx + b
m is the slope.
b is the y-intercept.
With a 3 filled in for slope and -2 filled in for the y-intercept, you get:
y = 3x + -2
is the same as,
y = 3x - 2
Answer:
c = -2
Step-by-step explanation:
4(3+c)+c=c+4 =
4(3+c)+c-c=c+4-c =
4(3+c)=4 =
[4(3+c)]/4=4/4 =
3+c=1 =
3+c-3=1-3 =
c = -2
Answer:
10 2/3
Step-by-step explanation:
16 x 2/3
32/3 or 10 2/3
Answer:
you did not provide the numbers to answer any question...
but the formula that you want is probably this one
Combination Formula nCr=n!(n−r)!r!
Step-by-step explanation:
Given:
Eighteen 2.5 gallon buckets are needed to fill a cistern with water.
To find:
The constant of variation.
Solution:
If y is directly proportional to x, then
Where, k is constant of variation.
In the given problem, water in cistern (w) is directly proportional to number of buckets (n).
(Capacity of each bucket is 2.5 gallons)
Therefore, the constant of variation is 2.5.
