Aleks [24]

Answer:

p= -1

Step-by-step explanation:

gradient=<u>y</u><u>²</u><u>-</u><u>y</u><u>¹</u>

<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>x²-x¹

-1 =<u>p</u><u>-</u><u>2</u>

<u> </u><u> </u><u> </u><u> </u><u> </u>9-6

-1=<u>p</u><u>-</u><u>2</u>

<u> </u><u> </u><u> </u><u> </u><u> </u> 3

multiply both sides by 3 to remove the denominators

-1×3=p-2

-3=p-2

put the like terms together

-3+2=p

-1=p

Answer:

∠APB = 106°

Step-by-step explanation:

Method 1: Focus on Triangle APB

Every angle of equilateral triangle ABC is 60°

∠BAP = 60°

∠ABP = 60° - 46° = 14°

Total degrees in one triangle is 180°

∠APB = 180° - 60° - 14° = 106°

Method 2: Exterior Angle Theorm

∠APB = ∠PBC + ∠PCB

∠APB = 46° + 60°

∠APB = 106°

Richard and Teo have a combined age of 20. Richard is 2 years older than twice Teo’s age. How old are Richard and Teo?

boyakko [2]

Richard is 14 years old and Teo is 6 years old.

Step-by-step explanation:

Let,

Richard's age = x

Teo's age = y

Combined age = 20 years

According to given statement;

x+y=20 Eqn 1

x = 2y+2 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(2y+2)+y=20\\2y+2+y=20\\3y=20-2\\3y=18$

Dividing both sides by 3

$\frac{3y}{3}=\frac{18}{3}\\y=6$

Putting y=6 in Eqn 2

$x=2(6)+2\\x=12+2\\x=14$

Richard is 14 years old and Teo is 6 years old.
