All you have to do is plug in the coordinates into the problem to see if it is true or false:

5x - 2y + 1 > 0

5(-2) - 2(-1) + 1 > 0

-10 - (-2) + 1 > 0

-8 + 1 > 0

-7 > 0    ... So the answer would be FALSE

Answer:

False

Step-by-step explanation:

5x - 2y + 1 > 0

plug in  the given  ordered pair  x= -2 and y = -1:-

5(-2) - 2(-1) + 1

= -10 + 2 + 1

=  -7  which is less than 0 therefore the answer is False

Answer:

m = 7

Step-by-step explanation:

2m + -4 = 10

Reorder the terms:

-4 + 2m = 10

Solving

-4 + 2m = 10

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 2m = 10 + 4

Combine like terms: -4 + 4 = 0

0 + 2m = 10 + 4

2m = 10 + 4

Combine like terms: 10 + 4 = 14

2m = 14

Divide each side by '2'.

m = 7

Simplifying

m = 7

David went to a fast-food shop for a meal in a late evening. Only steak, pork chop and grilled chicken were available for main c
Doss [256]

six

Step-by-step explanation:

the reason is this: let steak be (s), pork  be (p), grilled chicken be (gc), tea be (t), and coffee be (c)

now, we want to find the total number of outcomes, and this cannot be determined by a simple roll of the dice. you have to count the sample space required for EVERY outcome, and it has to lie within the conditions. so, assuming David only takes 1 main course and 1 drink, he would be down to six  option, which are :

1. s & t

2. s & c

3. p & t

4. p & c

5. gc & t

6. gc & c
