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 =
Formula for this case is
(a+b)∧3=a∧3+3a∧2b+3ab∧2+b∧3
(2x+5)∧3=(2x)∧3+3*(2x)∧2*5+3*2x*5∧2+5∧3=8 x∧3+3*4x∧2*5+3*2x*25+125=
=8x∧3+60x∧2+150x+125
Good luck!!!
The answer is y = 3x - 2. To find slope, you subtract y2 - y1 and x2 - x1. In this case, y2 - y1 = 10 - 4 and x2 - x1 = 4 - 2. You would result in 6/2, which can be reduced to 3. Your slope is 3, so the first and second answer automatically are eliminated. Next, you could either draw it out on a coordinate plane or just visualize it. The starting point that goes through each line would be -2, which means D, or y = 3x - 2, is the correct answer.
When you round 9.55555 to the nearest hundredth you would get 9.56 which you would then round to 10
