Simplify.
3x^2−7x+9 - 2x^2+4x−8
1. 3x^2-2x^2 = x
2. -7x + 4x = -3x
3. 9 - 8 = 1
Combine.
x -3x +1
Thus, 2x^2+4x−8 is x -3x +1 less than 3x^2−7x+9
Answer:
Hi! The correct answer is (1448/3, 686)
Step-by-step explanation:
<u><em>~Solve for the first variable in one of the equations, then substitute the result into the other equation~</em></u>
The equation is -3x/y
Plug in the numbers given for x and y
-3(10)/-3.5
-30/-3.5
divide and that's your answer
Answer:
3rd Option
Step-by-step explanation:
When you find the ratio of the 2 triangles, it is 14/5, so the 2nd option and 4th option are out of the park (The triangles are indeed similar). You are left with options 1 and 3. Option 3 is the best answer as you have to match the vertices of each triangle to each other.
