Answer:

2. (5, -5)

3. (-3, 2)

4. (2, 4)

Step-by-step explanation:

Each vertex can be found using two simple steps.

1) The number being added or subtracted from x.

-The x coordinate of your vertex is the opposite of that number.

2) The number after the absolute value symbol.

-The y coordinate is that value.

Victoria is 4 years older than her neighbor. the sum of their ages is no more than 14 years.enter an inequality that can be used

elena55 [62]

V is 4 more tha x
v=4+x
sum is no more than 14
v+x≤14

sub 4+x for v
4+x+x≤14
4+2x≤14
minus 4 both sides
2x≤10
divide both sides by 2
x≤5
5+4=9

the neighboor's age is at most, 5 years
and victoria is 9 at most

Answer:

The system of inequalities is

$2x+10y\leq 40$

$x+y\geq 5$

The solution in the attached figure

Step-by-step explanation:

<u><em>The question is</em></u>

Write a system of linear inequalities.

x ---> number of scarves knitted per week

y ---> number of knitted sweaters per week

we know that

Mary would like to spend no more than 40 hours per week knitting

The word "No more" means "less than or equal to"

$2x+10y\leq 40$ ----> inequality A

Mary would like to knit at least 5 items per week

The word "at least" means "greater than or equal to"

$x+y\geq 5$ ----> inequality B

Solve the system by graphing

The solution is the triangular shaded area

see the attached figure
