Iiiiiiiidddddddddkkkkkkkkk

  • Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept

So remember that <u>parallel lines have the same slope.</u> And since Line a's slope is 5/7, and line a and b are parallel to each other, this means that <u>line b's slope is 5/7.</u>

Factorise the following​
Irina18 [472]

Answer:

see explanation

Step-by-step explanation:

(a)

2x + 10 ← factor out 2 from each term

= 2(x + 5)

(b)

5x - 15 ← factor out 5 from each term

= 5(x - 3)

(c)

8x + 6 ← factor out 2 from each term

= 2(4x + 3)

(d)

12x - 8 ← factor out 4 from each term

= 4(3x - 2)

Factor the polynomial completely using the X method. X2 13x – 48 An x-method chart shows the product a c at the top of x and b a
Ratling [72]

X method is the method to find the factors of the polynomial equation.The factor of the given polynomial is,

x^2+16x-3x-48=(x+16)(x-3)

Thus the option 3 is the correct option,

<h3>How to find factor of polynomial using X method?</h3>

X method is the method to find the factors of the polynomial equation.

The standard form of the quadratic equitation is given as,

ax^2+bx+c

Given information-

The equation given in the problem is,

x^2+13x-48

Compare the above equation with the standard form. We get,

a=1\\b=13\\c=-48

To find out the factor of above equation using X method, follow the steps.

  • Step 1) Multiply a and c and place ac at the top of X as shown in the image.

        ac=1\times(-48)\\ac=-48

  • Step 2) Place b at the bottom as shown in the image below.

       b=13

  • Step 3) Find two numbers that multiply the top number ac and to the bottom number b.

  • Step 4) Write the polynomial from the X box as,

         x^2+16x-3x-48=x(x+16)-3(x+16)

         x^2+16x-3x-48=(x+16)(x-3)

Hence the factor of the given polynomial is,

x^2+16x-3x-48=(x+16)(x-3)

Thus the option 3 is the correct option,
