Answer:
x = -4; y = -3
Step-by-step explanation:
2x - 5y = 7
3x - y = -9
Rewrite top equation. Multiply both sides of bottom equation by -5. Add equations. This eliminates y, and we solve for x.
2x - 5y = 7
(+) -15x + 5y = 45
----------------------------
-13x = 52
Divide both sides by -13.
x = -4
Substitute -4 for x in the first original equation and solve for y.
2x - 5y = 7
2(-4) - 5y = 7
-8 - 5y = 7
-5y = 15
y = -3
Answer: x = -4; y = -3
-5 =
I think BD is 16 and EC is 9. hope this helps
The two bottom graphs demonstrate translations.
<h3>
Which figures demonstrate a translation?</h3>
We will have a translation only if:
- The size of the figure does not change (like in option 1, which we can discard).
- If the "direction" of the figure does not change, like in option 2, where you can see that there is a reflection.
The images where the figures are only moved a little bit are the ones that demonstrate just a translation, and these are the two lower ones.
