Mathematics
1 answer:

Answer:

True

Step-by-step explanation:

Dilation changes the size of the image so therefore it can't be congruent with the pre-image as congruent means the same.

8(-2x+1)=30-(-4+3x)<br><br> solve for x
Fittoniya [83]

Answer:

-2

Step-by-step explanation:

8 (-2x + 1) = 30 - (-4 + 3x)   Distribute

-16x + 8 = 30 + 4 - 3x  Combine like terms

-16x + 8 = 34 - 3x   Rearrange terms

-13x = 26 Divide by -13 on both sides

x = -2

If 2x² – 2y = 125 and x - y = 2.5, find the value of<br> x + y
uysha [10]

We can solve this using substitution.

because x-y=2.5

x=y+2.5

Now substitute x into other equation.

2(y+2.5)^2-2y=125

2y^2+10y+12.5-2y=125

2y^2+8y-112.5=0

Now comes the ugly part

y=-4+-sqrt(16+900)

y=-4+-sqrt916

y=-4+-2sqrt229

x=-1.5+-2sqrt229
