The son is 4 years old and the dad is 24 years old.
Answer:
B
Step-by-step explanation:
It has a slope of -1/4
and it's y intercept is 2
y = -1/4x + 2
The correct answer is C as it has the same line of equation. We can make this clear by verifying that these two points make the same equation or not. So as we can see if we calculate the gradient using the formula y2 - y1 / x2 - x1.
As we now know that the gradient is -1. We can simply put any one point in the equation y - y1 = m(x - x1) to get the line of equation. WHen we calculate the line of equation it come out to be y = -x + 7
Answer:
The ratio of blue to red marbles is 3 to 8.
Hope this helps :) have a good day!
It is both equations are equal to -0.076.
