Answer:

y = 6 * 3ˣ

Step-by-step explanation:

y = a * bˣ

(-1 , 2): 2 = a * (b)⁻¹ = a/b a = 2b

(2 , 54) 54 = a * b² = 2b * b² = 2b³

b³ = 54/2 = 27 b = 3

a = 6

Function: y = 6 * 3ˣ

Solve the system of equations:<br> y = x + 2<br> y = x2 + 5x + 6<br> HELP PLZ

soldier1979 [14.2K]

Answer:

x=2(twice)

y=0(twice)

Step-by-step explanation:

This question can be solved using substitution method

So let's solve

y=x+2....(1)

y=x2+5x+6....(2)

Substitute (1) into(2)

X+2=x2+5x+6

Collect like terms

X2+5x-x+6-2=0

X2+4x+4=0

X2+2x+2x+4=0

X(x+2)+2(x+2)=0

(X+2)(x+2)=0

X+2=0

Substrate 2 from both sides

X=-2

X+2=0

X=-2

Let's substitute the value of x into (1)

y=x+2

y=-2+2

Y=0(twice)
