It is the last one. A closed circle means less than or equal to, so that crosses out the top two. The third says five is greater and we know that is not true because the line is decreasing in value. It must be the fourth.

What is the value for x in the form of p does 4(px+1)=64

spayn [35]

Step-by-step explanation:

4(px + 1) = 64

Step 1: Add -4 to both sides.

4px = 60

Step 2: Divide both sides by 4p.

4px = 60

Answer:

a) x =3 and x=5

c) x =-1 and $x = \frac{-7}{3}$

i) x =0 and $x = \frac{-9}{2}$

Step-by-step explanation:

Given that the quadratic equation

x² - 8x +15 =0

The factors of 15 = 5 × 3

x² - 5x -3x +15 =0

x(x -5) -3(x-5) =0

(x-3)(x-5) =0

x =3 and x=5

3 x² + 10 x +7 =0

⇒ 3x² + 3x + 7x +7 =0

⇒ 3x (x +1) +7(x+1) =0

⇒ (x+1) ( 3 x +7) =0

⇒ x =-1 and $x = \frac{-7}{3}$

2 x ² + 9 x =0

⇒ x( 2 x + 9) =0

⇒ x =0 and 2 x = -9

⇒ x =0 and $x = \frac{-9}{2}$
