Ede4ka [16]3 years ago

Answer:

product of the roots= c/a

Step-by-step explanation:

The the two roots(α and β) of the quadratic equation ax²+bx+c=0  as given by shridharacharya formula are

\alpha= \frac{-b+\sqrt{b^2-4ac} }{2a}

\beta= \frac{-b-\sqrt{b^2-4ac} }{2a}

now product of the roots

αβ= \frac{-b+\sqrt{b^2-4ac} }{2a}×\frac{-b-\sqrt{b^2-4ac} }{2a}

use formula (a+b)(a-b)= a^2-b^2 and solve we get

αβ= c/a

therefore product of the roots= c/a

The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

<u>Step 1: Define</u>

y = 3/4x + 2

<u>Step 2: Break Function</u>

<em>Identify Parts</em>

Slope <em>m</em> = 3/4

y-intercept <em>b</em> = 2

Which step can you use to solve the equation m+9=-2? <br> please help !!
nexus9112 [7]

Answer:

Subtract 9 from each side of the equation.

m = – 11

Step-by-step explanation:

m + 9 = – 2

To solve the above equation, we simply subtract 9 from each side of the equation.

This is illustrated below:

m + 9 = – 2

Subtract 9 from each side of the equation

m + 9 – 9 = – 2 – 9

m + 0 = – 11

m = – 11

Therefore, the value of m is – 11
