The answer is 65. Because if you use the discriminant formula which is b^2 - 4(a)(c)

Explain prime factorization

kozerog [31]

Prime factorization is when a number can only be multiplied by 1 so 2 is a prime number because nothing times it self equals 2 or nothing but 1 ×2 is 2 prime factorization is just using prime numbers to break down bigger number like 50 5 and 10 and break down the 10 2 and 5

find the equation of the line using the slope formula. Write the final equation using the slope-intercept form. the x- intercept

Roman55 [17]

Answer:

$y=- 4x + 4$

Step-by-step explanation:

The slope formula for a straight line is:

$y=mx+b$

Where, 'm' is the slope and 'b' is the y-intercept.

To find the x-intercept of a line, we need to equal 'y' to zero, and then solve for 'x'. In this case we know that the x-intercept is 1, so we have the point (x1, y1)=(1,0). We are given a second point which is: (x0, y0)=(-2, 12).

To find the slope, we use the following formula:

$m = \frac{y1-y0}{x1-x0} = \frac{0-12}{1-(-2)} = -4$

Now, The equation of the line is: y - y0 = m(x-x0). Then, substituting the values of 'm', 'x0' and 'y0' we have that:

$y - 12 = -4(x+2) ⇒ y = -4x-8 + 12 ⇒ y=- 4x + 4$

The equation of the line using the slope-intercept form is:

$y=- 4x + 4$
