I need to step-by- step ways on how this is or isn’t a solvable equation. Please HELP
Darya [45]

Answer:

it is a solvable equation

Step-by-step explanation:

(x + 2) -3(x - 4) = 6 and x = 4

if x = 4 then fill in all the x's with 4 so the equation is now:

(4 + 2) -3(4 - 4) = 6

Use PEMDAS

Now the equation is 6 - 3(0) = 6

-3 times 0 is 0 so it's 6-0=6

6 = 6

when you put the 4 in for the x variables and the numbers on both sides of the equal sign are the same it makes the equation true

hope this makes sense and hope it helps :)

What is the Co ordinates to fill in the grid in the top left?
wolverine [178]

Answer:

a ) x = - 3, y = 5

x = 0, y = 2

x = 5, y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

Step-by-step explanation:

y = 2 - x

When x = - 3,

y = 2 - x

= 2 - ( - 3 )

= 2 + 5

y = 7

When x = 0,

y = 2 - x

= 2 - 0

y = 2

When x = 5,

y = 2 - x

= 2 - 5

y = - 3

b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

A parabola has a vertex at (4, 0) and passes through the point (6, 1). Which of the following is the equation of this parabola i
Doss [256]
Easy

y=a(x-h)^2+k
vertex is (h,k)
we know that vertex is (4,0)
input that point for (h,k)
y=a(x-4)^2+0
y=a(x-4)^2
passes thorugh the point (6,1)
input that point to find a
1=a(6-4)^2
1=a(2)^2
1=a(4)
divide both sides by 4
1/4=a

thefor the equation is
y=(1/4)(x-4)^2
or
y=(1/4)x^2-2x+4
