Answer:
Therefore the value of x is 5.
Step-by-step explanation:
Given:
△ABC ≅ △DEF,
EF = x 2 - 7, and
BC = 4x - 2.
To Find:
the values of x. = ?
Solution:
△ABC ≅ △DEF ........Given
If two Triangles are congruent then the Corresponding Parts of Congruent Triangles are Congruent.
∴ BC ≅ EF ...................CPCTC
Substituting the values we get
![4x-2=x^{2}-7\\x^{2}-4x-5=0](https://tex.z-dn.net/?f=4x-2%3Dx%5E%7B2%7D-7%5C%5Cx%5E%7B2%7D-4x-5%3D0)
Now By Factorizing we get
![x^{2}-5x+x-5=0\\x(x-5)+1(x-5)=0\\(x+1)(x-5)=0\\x+1=0\ or\ x-5=0\\x=-1\ or\ x=5\\x\ cannot\ be\ negative\\\therefore x=5](https://tex.z-dn.net/?f=x%5E%7B2%7D-5x%2Bx-5%3D0%5C%5Cx%28x-5%29%2B1%28x-5%29%3D0%5C%5C%28x%2B1%29%28x-5%29%3D0%5C%5Cx%2B1%3D0%5C%20or%5C%20x-5%3D0%5C%5Cx%3D-1%5C%20or%5C%20x%3D5%5C%5Cx%5C%20cannot%5C%20be%5C%20negative%5C%5C%5Ctherefore%20x%3D5)
Therefore the value of x is 5.

Hope that helps!
y<2x+2
2 is your y intercept and your slope is 2 (positive)
no or equal to so we have a positive slanted dotted line
your answer is the last one
