Slope = Change in y / Change in x
= 8 - 2 / 3 - 1
= 6 / 2
= 3
Answer:
A (361)
Step-by-step explanation:
A "perfect square trinomial" has the form
ax^2 + 2ab + b^2. If a happens to be 1, which it is in the given x^2 − 19x + c, then 2(1)(b) = - 19. Solving for b, we get b = -19/2.
Then b^2 in the general "perfect square trinomial" is the same as c: (-19/2)^2, or 90.25, or 90 1/4, or 361/4/
Choosing A (361) makes the given expression a perfect square trinomial.
Answer:
8
Step-by-step explanation:
Distance= √(-4-4)² + (7-7)²
= √(-8)² + (0)²
= √64
= 8

Step-by-step explanation:
Rate of change means how much does the number of snowflakes go up each time (on a different question you might find the number goes down each time)
"Initial value" means whatthe number if snowflakes at step zero. We have to work backwards to find that number. For the equation, fill in the rate in front of the x (we use m for that number) and add in the initial value (b) in the format y=mx+b . The information for the table is in the picture (the step numbers and number of snowflakes)
