The answers to the numbers are shown below.
1.) Divide both sides by two to yield an answer of n > 7.
2.) Cross multiply by multiplying the denominator, 5, by 11. This gives an answer of n ≥ 55.
3.) Divide both sides by -3. Since we have an operation involving a negative number, we invert the sign. Thus, the answer is y ≥ 6.
Answer:
It’s depends on the sign.
Step-by-step explanation:
For example if your question is 3x+16y-8-7x+8y then the answer would be -4x+24y-8 if they have the same variable look at them as a separate equation.
Answer:
y = -1/2x - 1
Step-by-step explanation:
We can use the point-slope form of the equation:
y-y1 = m(x-x1)
Where the given y1 = -2, x1 = 2, and m = -1/2. This yields:
y - (-2) = -1/2(x - 2)
y + 2 = -1/2x + 1
y = -1/2x +1 - 2
y = -1/2x - 1
Answer: E = 56
Step-by-step explanation:
E is proportional to √C
To remove proportionality, introduce a constant (k).
E = k × √C
From question,
E = 40 and C = 25
So,
40 = k ×√25
40 = k × 5
k = 8
Now,
C = 49
k = 8
E = ?
E = k√C
E = 8 × √49
E = 8 × 7
E = 56
