Answer:

Linear, the linear term is -21x and the constant term is -20. Last option is the answer

Step-by-step explanation:

We are given the following function:

$y = (x - 5)(5x + 4) - 5x^2$

First we have to simplify y, before solving the question:

$y = (x - 5)(5x + 4) - 5x$

Applying the distributive property:

$y = 5x^2 + 4x - 25x - 20 - 5x^2$

$y = 0x^2 - 21x - 20$

$y = -21x - 20$

No quadratic term, so it is linear.

The linear term is -21x and the constant term is -20.

34kurt

Answer: the cost of a milkshake is $2.59

Step-by-step explanation:

Let x represent the cost of a banana split.

Let y represent the cost of a milkshake.

At the ice cream shop, one banana split and five milkshakes cost $16.24. This is expressed as

x + 5y = 16.24- - - - - - - - - - - - -1

If three banana splits and two milkshakes cost $15.05. This is expressed as

3x + 2y = 15.05- - - - - - - - - - - - -2

Multiplying equation 1 by 3 and equation 2 by 1, it becomes

3x + 15y = 48.72

3x + 2y = 15.05

Subtracting, it becomes

13y = 33.67

y = 33.67/13

y = 2.59

Substituting y = 2.59 into equation 1, it becomes

x + 5 × 2.59 = 16.24

x + 12.95 = 16.24

x = 16.24 - 12.95

x = 3.29

Examine the diagram and information to answer the question. Square ABCD has vertices at A(−2,1), B(2,7), C(8,3), and D(4,−3). Ho

BigorU [14]

Answer:

Option (1)

Step-by-step explanation:

Coordinates of the vertices are A(-2, 1), B(2, 7), C(8, 3) and D(4, -3)

Since ABCD is a square,

Perimeter of a square = 4 × (length of a side)

= 4 × (AB)

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Therefore, distance between two points A(-2, 1) and B(2, 7) will be,

AB = $\sqrt{(2+2)^2+(7-1)^2}$

AB = $\sqrt{4^2+6^2}$

AB = $\sqrt{52}$

AB = $2\sqrt{13}$

Now area of square ABCD = 4 × $2\sqrt{13}$

= $8\sqrt{13}$ unit

Therefore, option (1) will be the answer.
