Answer:

He have to eat each piece in  \frac{1}{3} \ minute.

Step-by-step explanation:

Given:

Brian claims that he can eat a pie that is divided into six equal pieces In two minutes.

If he can eat the whole pie in two minutes.

Now, to find the time he have to eat for each piece.

So, to solve by using unitary method:

If Brian can eat 6 pieces in = 2 minutes.

Then, he can eat 1 piece in = \frac{2}{6} =\frac{1}{3} \ minute.

Therefore, he have to eat each piece in \frac{1}{3} \ minute.

75/3=25....

ratio is not the same

Its hard to tell....You must know exact cordinations

I can tell you this

I can say this if y=60 and x=2 and....y=120 and x=4...then it is propotional...but it seems not..

The tables below show the values of Y for different values of X
pogonyaev

Answer:

Option D

Step-by-step explanation:

Rate of change of a linear function between two points (x_1,y_1) and (x_2,y_2) is given by,

Rate of change 'm' = \frac{y_2-y_1}{x_2-x_1}

From the given table,

Rate of change of the function between (-2, 6) and (-4, 9),

Rate of change 'm' = \frac{9-6}{-4-(-2)}

                           m = \frac{3}{-2}

Initial value = y-intercept

Let the equation of the line passing through a point (h, k) is,

y - k = m(x - h)

If a point (-2, 6) is lying on the graph of the function,

y - 6 = -\frac{3}{2}(x+2)

y = -\frac{3}{2}x-3+6

y = -\frac{3}{2}x+3

Y-intercept of the function = 3

Therefore, initial value of the function = 3

Option D is the answer.

Solve: 37x + 41y = 70<br>41x + 37y = 86​
AysviL [449]

Step-by-step explanation:

37x + 41y = 70 --- R¹

41x + 37y = 86 --- R²

R¹ + R² : 78x + 78y = 156

78(x + y) = 156

x + y = 2 --- R³

R¹ - R² : -4x + 4y = -16

4(y - x) = -16

y - x = -4 --- R⁴

R³ + R⁴ : 2y = -2

y = -1

R³ - R⁴ : -2x = -6

x = 3
