(0, 9) represents the y-intercept of the graph.

Since the slope is 1/3, this means that y will rise 1 for every 3 that x runs.

The points that can be used to make a line in this graph are (3, 10) and (6, 11).

Which expression is equivalent to 64x^3-343
In-s [12.5K]

Answer:

B:  (4x - 7)(16x^2 + 28x + 49)

Step-by-step explanation:

64x^3-343 can be rewritten as 4^3x^3 - 7^3 or (4x)^3 - 7^3.  This is the difference of two cubes.  The appropriate formula for factoring such is

       a^3 - b^3 = (a - b)(a^2 + ab + b^2).  Therefore,

our (4x)^3 - 7^3 = (4x - 7)(16x^2 + 28x + 49).  This is Answer B.

Goshia [24]

Let

x-------> the number of dinner

y-------> the number of lunch

we know that

8x+5y \leq 42 -------> equation A

x=y ------> equation B

Substitute equation B in equation A

8[y]+5y \leq 42

13y \leq 42

y \leq 42/13

y \leq 3.23

so

the greatest number of lunch is y=3

x=y

Hence

the greatest number of dinner is x=3

therefore

the greatest number of meals is

x+y=3+3=6

<u>the answer is</u>

6
