Answer:

Perimeter = 6x-8

Step-by-step explanation:

a=x+5

b=2x-9

Perimeter = 2*(a+b)

Perimeter = 2*(x+5+(2x-9))

Perimeter = 2*(x+5+2x-9)

Perimeter = 2*(3x-4)

Perimeter = 6x-8

Which of the following could be the system of nonlinear inequalities graphed below?
Ivan

Answer:

Option A.

Step-by-step explanation:

step 1

we know that

The equation of the solid line is

y=5

The solution is the shaded area above the solid line

so

The equation of the first inequality is

y\geq 5

step 2

The equation of the dashed line is

y=x^{2} -5x+6

The solution is the shaded area above the dashed line

so

The equation of the second inequality is

y>x^{2} -5x+6

therefore

The system of inequalities could be

y\geq 5

y>x^{2} -5x+6

A cab charges $1.50 for the first mile and $0.50 for each additional mile. Write and solve an inequality to determine how many m
ValentinkaMS [17]
1.50 + 0.50(x-1) <u><</u> 25 

1.50 + 0.50x - 0.50 <u><</u> 25
1 + 0.50x <u><</u> 25
<u>-1                 -1</u>
      0.50x <u><</u> 24
  <u>    ÷0.50    ÷0.50</u>
               x <u><</u> 48

1.50 + 0.50x <u><</u> 25 ; x <u><</u> 47 miles     3rd option in the choices.

To check:

1.50 + 0.50(47) <u><</u> 25
1.50 + 23.50 <u><</u> 25
25 <u><</u> 25
