Answer:
y=1x+1
Step-by-step explanation:
We already know the Y intercept is 1 from the first set of points given
The change in x is 2 and the change in Y is also 2 so when you make the slope equation y/x you get 1
Pluggin in the numbers you get: y=1x+1
Answer:
$ 27.6.
Step-by-step explanation:
Let the cost of tea be C.
Let the mass of tea be M
From the question given, we were told that the cost of tea varies directly with the mass. This can be expressed as:
C & M
C = KM
K is called constant of proportionality.
C is the cost of the tea.
M is the mass of tea.
Next, we shall determine the constant of proportionality, K.
Cost (C) = $ 10.35
Mass (M) = 4.5 kg
Constant (K) =..?
C = KM
10.35 = K × 4.5
Divide both side by 4.5
K = 10.35/4.5
K = 2.3
Finally, we shall determine the cost of 12kg of tea as follow:
Mass (M) = 12 kg
Constant (K) = 2.3
Cost (C) =..?
C = KM
C = 2.3 × 12
C = $ 27.6
Therefore, the cost of 12 Kg of tea is $ 27.6
Answer:
3/8 mile
Step-by-step explanation:
The number of miles farther Raymond needs to walk to get to the bus stop is calculated as:
Total number of miles he needs to walk to the bus stop - Number of miles he has walked so far
Total number of miles he needs to walk to the bus stop = 3/4 mile
Number of miles he has walked so far = 3/8 mile
Hence,
3/4 mile - 3/8 mile
Lowest Common Denominator = 8
2 × 3 - 3 × 1/8
6 - 3/8
= 3/8 mile
Option c is correct
rs=3x , rt=6x-3 and st=3x.
We are given point s is between r and t points.
So, the end points are r and t.
Because s is between r and t, the sum of rs and st equals rt.
Weo, we can setup an equation as,
rs + st = rt.
Plugging values of rs , st and rt in above equation.
3x + 3x = 6x - 3.
Adding 3x+3x, we get 6x.
6x = 6x - 3
Subtracting 6x from both sides, we get
6x-6x = 6x-6x - 3 .
0=-3.
But that is not possible.
So, we could say, rs + st = rt could not be possible for given values of rs, st and rt, that is rs=3x , rt=6x-3 and st=3x.
For the given points and , we have to find the ordered pair that represents YZ.
YZ is calculated by finding the difference between the coordinates Z and Y.
So,
Magnitude of coordinate (x,y) is calculated by the formula =
Magnitude of YZ=
=
units.
