What is the rate of change of the linear relationship modeled in the table? (4 points) x y −2 5 −1 4 0 3 1 2 a −2 b −1 c negativ

Ostrovityanka [42]

Answer:

rate of change=slope= y2-y1/x2-x1

Step-by-step explanation:

x: -2|-1|0|1

y : 5|4|3|2

so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)

now we plug them in: $\frac{4-5}{-1-(-2)}$

4-5=-1

-1-(-2)=1

so -1/1 is equal to -1, meaning it's answer option b.

Tickets for admission to a high school football game cost $3 for students and $5 for adults. During 1 game, $2995 was collected

Sveta_85 [38]

Answer:

Number of student tickets = 325

Number of adult tickets = 404

Step-by-step explanation:

Let,

x be the number of student tickets

y be the number of adult tickets

According to given statement;

x+y=729 Eqn 1

3x+5y=2995 Eqn 2

Multiplying Eqn 1 by 3

3(x+y=729)

3x+3y=2187 Eqn 3

Subtracting Eqn 3 from Eqn 2

(3x+5y)-(3x+3y)=2995-2187

3x+5y-3x-3y=808

2y=808

Dividing both sides by 2

$\frac{2y}{2}=\frac{808}{2}\\y=404$

Putting y=404 in Eqn 1

x+404=729

x=729-404

x=325

Hence,

Number of student tickets = 325

Number of adult tickets = 404

Can some one explain to me how I do it step by step to understand and with answer what is the area and perimeter and type please

frozen [14]

This is a square. because the lengths and the widths are equal. I mean, all four sides are equal.

the area of a square is the square of a side
${s}^{2} = {5.4}^{2} = 29.16$

and the perimeter of a square is a side multiplied by 4
$4s = 4 \times 5.4 = 21.6$

hope this helps

good luck
