Subtracting a negative would make it a positive, so the new expression would be 13 + 17.

13 + 17 = 30.

Hope this helped and Happy Thanksgiving!

Given market demand Qd=50-p, and market supply p=Qs+5.what would be the state of the market if market price was fixed at Birr 25

Lemur [1.5K]

The state of the market if market price was fixed at Birr 25 per unit is excess demand

<h3>Quantity demanded</h3>

Qd = 50 - p

p = Qs + 5

p - 5 = Qs

if market price was fixed at Birr 25 per unit?

Qd = 50 - p

= 50 - 25

Qd = 25

Qs = p - 5

= 25 - 5

Qs = 20

The state of the market if market price was fixed at Birr 25 per unit is excess demand (demand greater than supply) leading to an increase in price.

Which quadratic regression equation best fits the data set?

nata0808 [166]

Answer: $y = 1.87x^2 -5.16 x + 10.54$

Step-by-step explanation:

Since the general quadratic equation is,

$y = ax^2 + bx+c$

Here the given table is,

x 1 2 3 4 5 6 7

y 5.9 8.9 13.4 20.1 30.1 45.1 67.7

By the graphing calculator,

a = 1.87024 ≈ 1.87

b= -5.15833 ≈ -5.15

c = 10.5429 ≈ 10.54

By putting the values of a, b and c,

The required quadratic equation is,

$1.87 x^2 -5.15x + 10.54$

⇒ First Option is correct.

The table below shows some values that satisfy a linear function.

Makovka662 [10]

Answer:

1.5

Step-by-step explanation:

Given the pair of points on the table.

Now the formula for slope, $m=\dfrac{y_2-y_1}{x_2-x_1}$

To calculate the slope we only require two pair of points.

Let us take: $(x_1, y_1)=(-5,0)$ and (x_2, y_2)=(-3,3)$

$m=\dfrac{3-0}{-3-(-5)}\\=\dfrac{3}{-3+5}\\=\dfrac{3}{2}\\m=1.5$

The slope of the linear function represented by the values in the table is 1.5.

Note: You can use any two set of values. The result will be the same.
