Answer:
d= -5
Step-by-step explanation:
The slope of a line is found by finding the ratio of change is y values to change is x values

The points on the line have coordinates at: (-1,7) (-3,d)
where ;

Applying the formula with values as;

The value of d = -5
The coordinates of the points (-1,7) (-3,-5)
<h2>sorry I can't help you to solve the equation</h2>
So, h(t) is how far is Daniel's head from the surface of the water, namely the surface itself is when the height is nill, so his head is at the surface and the height of it is just 0, thus h(t) = 0. Namely, what is "t" when h(t) is 0?

clearly the seconds cannot be a negative unit, so is not -3/2.
Step-by-step explanation:
just opposite it mesn 113/14
1/2 + 4x = 5x - 5/6
1/2 = x - 5/6
3/6 = x - 5/6
x = 8/6
