Larry makes sandwiches for lunch everyday. He can make 6 sandwiches with every 3 tomatoes he buys. If he bought 6 tomatoes, how
malfutka [58]

Answer:

12 sandwiches

Step-by-step explanation:

Make a proportion

He can make 6 sandwiches with 3 tomatoes, and x sandwiches with 6 tomatoes

6/3=x/6

Multiply both sides by 6 to isolate the variable, x

6*6/3=x/6*6

12=x

So, with 6 tomatoes, he can make 12 sandwiches

Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t >14 – 4t?
Stells [14]

Answer:

Option (C)

Step-by-step explanation:

There are two inequalities,

t - 4 ≥ 4t + 8 ------(1)

3t > 14 - 4t ------(2)

By simplifying inequality (1),

t - 4 ≥ 4t + 8

t ≥ 4t + 8 + 4

t ≥ 4t + 12

t - 4t ≥ 12

-3t ≥ 12

t ≤ \frac{12}{(-3)}

t ≤ -4

By solving inequality (2),

3t > 14 - 4t

3t + 4t > 14

7t > 14

t > \frac{14}{7}

t > 2

From the given graphs, Option (C) will be the answer.

A problem contains the points (0,0),(1,-2) and (-1,-4). What is the equation of this parabola in standard form?
Bas_tet [7]

Answer:

The general equation of the parabola     y = -3 x² + x

Step-by-step explanation:

<u><em>Step(i):- </em></u>

Given points are (0,0) , (1, -2) and ( -1 , -4 )

Given the standard parabola

                                y = ax²+ b x + c ...(i)

Passing through the point (0,0)

                              c = 0

Passing through the point (1,-2)

                            -2 = a(1) +b(1)

                   a + b = -2 ...(ii)

Passing through the point (-1, -4)

                        - 4 = a - b

               a - b = -4 ...(iii)

<u><em>Step(ii)</em></u>:-

Adding (ii) and (iii) equations , we get

            2 a = -6

              a = - 3

substitute   a = - 3 in equation (ii)

       -3 + b =-2

             b = -2 + 3 = 1

<u><em>Final answer:</em></u>-

The general equation of the parabola

              y = ax²+ b x + c

             y = -3 x² + x + 0

             y = -3 x² + x
