78 Solve for x, with variables on both sides of equation. (Note: x is the same thing as 1x) You must show your work!

Feliz [49]

9x= x+4

Subtract x on both sides to balance the equation.

8x= 4

Divide 8 into both sides. (the inverse of multiplication)

x= 1/2

We can check this by plugging in x.

9(.5)= .5+4

4.5= 4.5

I hope this helps!

Graph the image of this triangle after a dilation with a scale factor of 2 centered at the origin.

Svet_ta [14]

Answer:

Since, the coordinates of the given triangle are (0,0), (4,-4) and (-4,-2)

In the dilation by the scale factor k with centered at origin,

$(x,y)\rightarrow (kx,ky)$

Thus, If the dilation occurs by the scale factor of 2 with centered at origin,

New coordinates of the triangles are,

$(0,0)\rightarrow (2\times 0, 2\times 0)$

$(-4,4)\rightarrow (2\times -4, 2\times 4)$

$(-4,-2)\rightarrow (2\times -4, 2\times -2)$

Thus, the coordinates of new triangle are,

(0,0) ( -8, 8) and (-8,-4)

spayn [35]

Answer:

y = 3x + 6

Step-by-step explanation:

y = ax + b, and since we know the gradient =>

y = 3x + b

y(-1) = -3 + b = 3 => b = 6
