Answer:
- 515
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 15 and d = - 35 - (- 15) = - 35 + 15 = - 20, thus
= - 15 + (25 × - 20) = - 15 - 500 = - 515
-515
In this example the first value is −15 and every value afterwards is 20 less.After substituting these values to above formula, we obtain: All we have to do is add 25 twenties or 25 x 20 = 500 and -15 - 500 = -515
10 hot dogs and 5 hamburgers your graph would be 2y:1x
x = 71 and y = 45
(x + 7)^2 + (y + 3)^2 = 4
The standard equation of a circle is:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius. We can substitute the information given to obtain:
