Answer:
Step-by-step explanation:
Given system:
- x + 4y = -8
- -1/4x + y = -1
1. Multiply the second equation by - 4 to get:
- (- 4)(-1/4x + y ) = (- 4)(- 1)
- x - 4y = 4
2. Now, add this up with the first equation:
- x + 4y + x - 4y = - 8 + 4
- 2x = - 4
- x = - 2
3. Find the value of y:
- - 2 + y = - 8
- y = - 8 + 2
- y = - 6
The solution is (- 2, - 6)
Answer:
the missing side value is 6.7.
Step-by-step explanation:
so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.

Dilation and reflection
-multiplication of - =reflection
example -(x)
-multiplication of any number other than 1=dilation
example 3x
-addition/subtraction inside the function=horizontal translation
Example (x-3)
-addition/subtraction outside the function=vertical translation
Example x-3
