Answer: -28 + 8 = -20
Step-by-step explanation:
This is simple. If a dolphin is at -28 ft. below sea level and it is going up towards the surface. You add because it is going up and you are adding more feet. You subtract if it is going deeper into the water and that is because it is going further away from sea level. Sea level is 0. Above is positive. Down is negative.

The zeros of the quadratic function when y = 0
so (-5 , 0) and (-2 , 0)
Answer
C) x = -2 and x = -5
Answer:
x = 1 and y = - 4
Step-by-step explanation:
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line goes through.
Here the line passes through (1, - 4) with x- coordinate 1, thus
x = 1 ← equation of vertical line
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line goes through.
Here the line passes through (1, - 4) with y- coordinate - 4, thus
y = - 4 ← equation of horizontal line
Answer:
to find a y-value, plug in any number for <em>x</em> in the equation and then solve the equation for <em>y</em>.
if you're given a table that has x-values filled in, plug each of those in for <em>x </em>in order to solve for their corresponding y-value.
if the table is blank, pick whatever numbers you want to use as x-values. don't use any numbers that are astronomically large, though. i always find that the best, most basic numbers to stick with are -2, -1, 0, 1, and 2.
i hope this helps! have a lovely day <3
