Answer: If a solution results in zero when subsitituted into the denominator of the equation, the solution is extraneous.
This is because you obtained the solution from a simplified version of the original equation, but you have to check if the solution obtained is a real solution of the original equation
In the case that when you substitute the solution in the original version the denominator becomes zero, this solution must be rejected, because the division by zero is not defined.
Answer:
m<CGD = 26°
m<CGF = 100°
Step-by-step explanation:
m<CGD = 2x - 2
m<EGF = 37
m<CGF = 7x + 2
Since GE bisects <DGF, m<DGF = 2*m<EGF.
m<DGF = 2*37 = 74°
m<CGD + m<DGF = m<CGF (angle addition postulate)
(2x - 2) + (74) = (7x + 2)
Find the value of x using the equation above.
2x - 2 + 74 = 7x + 2
Collect like terms
2x + 72 = 7x + 2
-2 + 72 = 7x - 2x
70 = 5x
70/5 = 5x/5
14 = x
x = 14
m<CGD = 2x - 2
Plug in the value of x
m<CGD = 2(14) - 2 = 28 - 2
m<CGD = 26°
m<CGF = 7x + 2
m<CGF = 7(14) + 2 = 98 + 2
m<CGF = 100°
The last one. because you are starting 1sec after the can has begun to pour. So, (1, 9.60) and the subsequent ordered pairs are correct
Step-by-step explanation:
May you reword it? I don't quite understand.
This line y = 4/5 x - 3 has slope = 4/5
Perpendicular lines, slope is opposite and reciprocal so slope of a line that is perpendicular to the line y = 4/5 x - 3 is -5/4
Answer
- 5/4
