Answer:

The slope is $\frac{7}{4}$ .

Step-by-step explanation:

Remember: $m = \frac{y_2 - y_1}{x_2 - x_1}$

☆And now we just plug in!

$m = \frac{1 - 8}{5 - 9} = \frac{ - 7}{ - 4} = \frac{7}{4}$

A piece of wire in the form of a rectangle with the dimensions 12 m by 10 m is bent to form a circle . Find the diameter of the

irakobra [83]

Answer:

14.01m

Step-by-step explanation:

Perimeter of the rectangular wire = circumference of the circle

Perimeter of the rectangular wire = 2(L+W)

Perimeter if the rectangular wire = 2(12+10)

Perimeter if the rectangular wire = 2(22)

Perimeter if the rectangular wire = 44m²

Circumference of the circle = πd

44 = πd

d = 44/3.14

d = 14.01m

Hence the circumference of the circle is 14.01m

Identify the values a, b, and c is the first step in using the quadratic formula to find the solution(s) to a quadratic equation

zlopas [31]

The values are a = 7, b = -9, c = -18.

<u>Step-by-step explanation:</u>

The given quadratic equation is $7x^{2} - 9x = 18$

The general form of the quadratic equation is $ax^{2} + bx + c = 0$

where,

a is the coefficient of x².
b is the coefficient of x.
c is the constant term.

Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.

So, bring the constant term 18 to the left side of the equation for equating it to zero.

⇒ $7x^{2} - 9x - 18 = 0$

Compare the above equation with general form $ax^{2} + bx + c = 0$

⇒ a = 7

⇒ b = -9

⇒ c = -18

Therefore, the values of a, b, and c are 7, -9 and -18.
