Answer:

Step-by-step explanation:

y = -5x

When x = -2 ; y = -5* (-2) = 10 ; (-2 , 10)

When x = -1 ; y = -5 *(-1) = 5 ; (-1 , 5)

When x = 0 , y = 0 ; (0 , 0)

When x = 1 ; y = -5 *1 = -5 ; (1 , -5)

When x = 2 ; y = -5 *2 = -10 ; (2 , -10)

Mark these points (-2 , 10) , (-1 , 5) , (0 , 0) , (1 , -5) , (2 , -10) and join them.

For every 5 coins carmen gets ,she gives 2 to her brother Frankie.If carmen has 9 coins,howmany coins does Frankie have?

FrozenT [24]

Answer:

Frankie have 6 coins

Step-by-step explanation:

For every 5 coins Carmen gets ,she gives 2 to her brother Frankie

Out of 5 coins, Carmen given 2 to her brother Frankie

So Carmen has 3 coins and Frankie has 2 coins

Ratio of coins , Frankie to Carmen is

2: 3

We need to find the number of coins Frankie has if Carmen has 9 coins

ratio of Frankie to Carmen is x : 9

Now make a proportion and solve for x

$\frac{2}{3} =\frac{x}{9}$

Cross multiply it

2*9 = 3*x

18 = 3x

Now divide both sides by 3

so x= 6

Frankie have 6 coins

Rufina [12.5K]

The 5 in x - 5 needs to be negative in the table. So, change that and make everything else in that row negative.

You are then left with 3x^2 + x - 15x - 5

Simplify to 3x^2 - 14x - 5

Please consider marking this answer as Brainliest to help me advance. If you have any questions, please let me know.

Bakery has bought 250 pounds of muffin dough. They want to make waffles or muffins in half-dozen packs out of it. Half a dozen o

Alexus [3.1K]

Answer:

250 batches of muffins and 0 waffles.

Step-by-step explanation:

-1

If we denote the number of batches of muffins as "a" and the number of batches of waffles as "b," we are then supposed to maximize the profit function

P = 2a + 1.5b

subject to the following constraints: a>=0, b>=0, a + (3/4)b <= 250, and 3a + 6b <= 1200. The third constraint can be rewritten as 4a + 3b <= 1000.

Use the simplex method on these coefficients, and you should find the maximum profit to be $500 when a = 250 and b = 0. So, make 250 batches of muffins, no waffles.

You use up all the dough, have 450 minutes left, and have $500 profit, the maximum amount.
