Answer:
m = -6/7
b = -2
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1) = (-2 - 4)/(0 - (-7)) = -6/7
y = mx + b
m = -6/7
y = -6/7 x + b
Use point (-7, 4).
4 = (-6/7)(-7) + b
4 = 6 + b
b = -2
y = -6/7 x - 2
m = -6/7
b = -2
Answer:
Ram: 21, Hari: 12
Step-by-step explanation:
To solve the problem, we can use the following notation. We call:
= Ram's age at present
= Hari's age at present
We know that:
- Ram is 9 years older than Hari --> mathematically, this can be written as
- Three years ago, Ram was two times as old as Hari was --> mathematically, this can be written as
where (r-3) is Ram's age 3 years ago, while (h-3) is Hari's age 3 years ago
Substituting eq.(1) into eq.(2), we find:
So, Hari's age is 12; therefore, Ram's age is
Answer:
Example 2 Solve for x and check: - 3x = 12. Solution. Dividing each side by -3, we obtain ... At this point we note that since we are solving for c, we want to obtain c on one side ... Example 7 Graph x > -5 on the number line.
Step-by-step explanation:
Whenever you reflect a point over the x axis, the x coordinate stays the same and the y coordinate is negated. In this case, the y coordinate which is 3 will be negated to become -3, and the x coordinate which is -5 will remain the same. Therefore, the new point is (-5,-3).
I hope this helps.
