Jika garis 4x+ay = 8 dan ay=9x + 5 saling tegak lurus, maka nilai a

We are given equations as

Firstly, we will write in slope intercept form of line

y=mx+b

Subtract both sides by 4x

now, we can divide both sides by a

we can find slope

so, we get

we are given second equation as

Firstly, we will write in slope intercept form of line

y=mx+b

divide both sides by a

we can find slope

we are given both lines are perpendicular

so, the multiplication of their slopes must  be -1

we can plug values

now, we can solve for a

Multiply both sides by a

now, we can solve for a

we get

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
