Answer:
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product
Step-by-step explanation:
Answer:
y = -x - 4
Step-by-step explanation:
the equation of a linear graph is y = mx + b
you know the m = -1
so now the equation is y = -x + b
from here, what you could do to find b is...
plug (-1, -3) into the equation
1) x = -1, y = -3
2) -3 = -(-1) + b
3) -3 = 1 + b
4) -4 = b
or you can look at the y-intercept which is where the line intersects with the y-axis
it seems to be (0, -4)
so "b" would be equal to -4
this makes the final equation y = -x + (-4) or y = -x - 4

Answer:
Jake
Step-by-step explanation:
The average rate of change is distance divided by time. You want both of their rates in feet per second. 60 feet divided by 10 seconds is 6 feet per second. 25 feet divided by 5 seconds is 5 feet per second. 6>5
