Answer:
(3, 1 )
Step-by-step explanation:
Given the 2 equations
x + 2y = 5 → (1)
3x + 5y = 14 → (2)
Rearrange (1) expressing x in terms of y by subtracting 2y from both sides
x = 5 - 2y → (3)
Substitute x = 5 - 2y in (2)
3(5 - 2y) + 5y = 14 ← distribute and simplify left side
15 - 6y + 5y = 14
15 - y = 14 ( subtract 15 from both sides )
- y = - 1 ( multiply both sides by - 1 )
y = 1
Substitute y = 1 into (3) and evaluate for x
x = 5 - (2 × 1) = 5 - 2 = 3
Solution is (3, 1 )
1. Input:1, output:4
2. Input:1, output:6
3. Input:5, output:8
3. Input:5, output:10
The different between the inputs and outputs are 3, 5, 3, 5. See the pattern?
Hope this helped.

Explanation:</h2><h2 />
Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll assume you want an explanation for polygons, quadrilaterals and parallelograms. So let's get started:
1. Polygon: A <em>polygon </em>is any flat shape that is closed and has straight lines as its sides.
2. Quadrilateral: A <em>quadrilateral </em>is a polygon that has four sides. Those sides can be either equal or not.
3. Parallelogram: A <em>parallelogram </em>is a polygon and also a quadrilateral because it has four sides such that the opposite sides are parallel and equal in length.
<u>In conclusion:</u>
- A parallelogram is both a polygon and a quadrilateral
- A quadrilateral is a polygon

Split it up
3x^2+12x-5x-20
group
(3x^2+12x)+(-5x-20)
factor
(3x)(x+4)+(-5)(x+4)
undistribute (x+4) like ab+ac=a(b+c)
(3x-5)(x+4)
Answer:
Reflect over x=-2 and dilate G'H'I' by a scale factor of 2 from point G
Step-by-step explanation:
First you'd have to reflect from x=-2 because its still on that line but the opposite way.
So we can already narrow it down to the second or last answer.
It wouldn't translate because that doesn't change the size. Its a dilation because the size has changed. Its dilated from point G because as you can see, G is the same point on both.
So the last answer choice is correct.
