This graph represents the relationship between the x and y.

s344n2d4d5 [400]

Answer:

Therefore, x is 1 and 2.

Step-by-step explanation:

As you plot both equations on the same graph, you will get something like this, shown in the graph.

Then, you have to find the x solutions where they intersect.

So, both equations intersect at x = 1 and 2.

Subtract 8 y^2 − 5 y + 7 from 2 y^2 + 7 y + 1 1 The answer is: −6y ^2 +12y+4

lys-0071 [83]

Answer:

$\large\boxed{-6y^2+12y+4}$

Step-by-step explanation:

$(2y^2+7y+11)-(8y^2-5y+7)\\\\=2y^2+7y+11-8y^2-(-5y)-7\\\\=2y^2+7y+11-8y^2+5y-7\qquad\text{combine like terms}\\\\=(2y^2-8y^2)+(7y+5y)+(11-7)\\\\=-6y^2+12y+4$

Emmit says the dilation can be represented by (1/2X, 1\2Y)Emily says the dilation can be represented by(1\3X, 1\3Y)Who is correc

schepotkina [342]

In the triangle LJK, the length of side LK=18.

In the triangle L'J'K', the length of side L'K'=6

Therefore,

$L^{\prime}K^{\prime}=\frac{1}{3}LK=\frac{1}{3}\times18=6$

Therefore, the scale factor for dilation is 1/3.

So, the dilation can be represented as

$\frac{1}{3}X,\frac{1}{3}Y$

So, Emily's statement is correct.
