So we have the equation:
Then we need to multiply by 4 on both sides to get rid of the denominator on the left:
Then we subtract 9 on both sides to solve for z:
Therefore the answer is z = -0.6.
Answer:A
Step-by-step explanation:
Answer:
2.3011
Step-by-step explanation:
This is because if you round this to the nearest tenth, the digit is 0 so it stays the same. When you round to the nearest hundredth, you would look at the 1 in the thousandth place and know that it is less than 5 so you would round down to 2.3. When you round to the nearest thousandth place, you would look at the very last number, which is less than 5, round down to 2.301 and realize that it is not equivalent to 2.3 :) I hope this helps
Answer: A = -3, B = 1, and C = 19 OR A = 3, B= -1, C = -19 (look at the explaination)
Step-by-step explanation:
You will need to expand the equation given to you.
y-7 = 3(x+4)
y-7=3x+12
y- 7 + 7 = 3x + 12 +7
y = 3x + 19
-3x + y = 19
Therefore, A = -3, B = 1, and C = 19
But, you can also write it as:
y = 3x + 19
3x - y = -19
A = 3, B= -1, C = -19
So, I don't know what your teacher wants but both answers should be right.
