Does the table below show a linear relationship between total cost of
balloons in dollars and the number of balloons purchased?

Answer:

D. y = 2x + 3​

Step-by-step explanation:

Use the table to answer the question.

x:-2  -1   0   1    2

y: -1   1   3   5   7

Which equation represents the relationship between x and y shown in the table.

Solution:

The table shows a linear relationship between x and y.

A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change (slope) and b is the value of y when x = 0.

The table (x, y) has the points (-2, -1) and (0, 3). The equation is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-(-1)= \frac{3-(-1)}{0-(-2)} (x-(-2))\\\\y+1=2(x+2)\\\\y+1=2x+4\\\\y=2x+3[/tex]

Answer: 200

Work: If the equation is 2x = 400, you just divide 2 on both sides, meaning the answer is x = 200

Answer:$630

Step-by-step explanation:

What is 80% of 350?

Y is 80% of 350

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 80% * 350

Converting percent to decimal:

p = 80%/100 = 0.8

Y = 0.8 * 350

Y = 280

then u add 280 to 350

Answer:

The length of side of patio is 11.27 feet.

Option A is correct option.

Step-by-step explanation:

Area of patio = 127 ft^2

We need to find side length of the patio.

Since the patio is square, the formula used is:

[tex]Area\: of\: square = l^2[/tex]

where l is the side length of square.

Now, putting value of area we can find area of square.

[tex]Area\: of\: square = l^2\\127=l^2\\Switching\:sides\:\\l^2=127\\Taking\:square\:root\:on\:both\:sides\\\sqrt{l^2}=\sqrt{127} \\l=11.27[/tex]

So, the length of side of patio is 11.27 feet.

Option A is correct option.

Answer:

7n+14

Step-by-step explanation:

There are two sides that both measure 2n+7, we need 2 of those

2n+7+2n+7=4n+14

We still have the third side left, 3n.

4n+14+3n

combine like terms

7n+14

Answer:

C) (4,-7)

Step-by-step explanation:

The value of w-v is (4, -7).

Coordinates is an address, which helps to locate a point in two-dimensional space.

Here, given coordinates;

v ≡ (-13, 2)    and    w ≡ (-9, -5)

Now, we need to find;

w - v ≡ (-9-(-13), -5 - 2)

        ≡ (-9+13 , -7 )

        ≡ (4, -7)

Thus, the value of w-v is (4, -7).
