Answer:
slope =2
y intercept = (0,-4)
Step-by-step explanation:
y = 2x - 4
Since this is in the form y = mx+b where m is the slope and b is the y intercept
The slope is 2 and the y intercept is -4
slope =2
y intercept = (0,-4)
Answer:
4: 32a^5 5: 2a / bc^2
Step-by-step explanation:
4. (2a)^3 / (2a)^-2
= (2a)^3 * (2a)^2
= 8a^3 * 4a^2
= 32a^5
5. 10a^7 b^9 c^6 / 5a^6 b^10 c^8
= 2a^7 b^9 c^6 / a^6 b^10 c^8
= 2a / bc^2
Answer:
The system of equations has no solutions
Explanation:
Given the system of equations:
3x - 9y + 9z = 44 ..........................................................(1)
2x + 6y - 5z = -18 ..........................................................(2)
x - 3y + 3z = 14 ...............................................................(3)
Solving by elimination, multiply (3) by 2
2x - 6y + 6z = 28 ............................................................(4)
Subtract (2) from (4)
-12y + 11z = 46 .................................................................(5)
Multiply (3) by 3
3x - 9y + 9z = 42 ............................................................(6)
Subtract (6) from (1)
0x + 0y + 0z = 30
This is impossible, and we conclude that the equation has no existing solutions
