Answer:the slope is 5
Step-by-step explanation: your slope is always next to your x remember the formula mx+b=y in this case m = slope and b=y intercept so 5 is your slope :)
Answer:
f(1)=10
f(n)=nf(n-1)+5
f(2)=2f(1)+5=2*10+5=25
f(3)=3f(2)+5=3*25+5=75+5=80
f(4)=4f(3)+5=4*80+5=320+5=325
f(5)=5f(4)+5=5*325+5=1625+5=1630

Answer:
Step-by-step explanation:
<u>Given equation:</u>
- x² + y² + 8x - 4y - 7 = 0
<u>Convert this to standard form by completing the square:</u>
- (x - h)² + (y - k)² = r², where (h, k) - center, r - radius
- x² + 2*4x + 4² + y² - 2*2y + 2² - 16 - 4 - 7 = 0
- (x + 4)² + (y - 2)² - 27 = 0
- (x + 4)² + (y - 2)² = 27
- (x + 4)² + (y - 2)² = (√27)²
The center is (- 4, 2) and the radius is √27
