Answer:
-1/3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.
c first:
and
and
c - 8 = 272 s0
c = 280
For a:
and
and
-34a = 3 so

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.
Answer:80
Step-by-step explanation:
31.205= 31
4.97=5
1.925=2
31*5/2=155/2=77.5=80 (1 significant figure)
Answer:
-450
Step-by-step explanation:
Say the first number is x to get the idea.
The first 150 terms are 150x - 5 * 150
15x - 750
300 - 750 = -450
Answer:
percentage change= 500%
Step-by-step explanation:
After diet the weight reduced = 30 pounds
Before diet her weight = 180 pounds
percentage change = { (180 - 30) ÷ 30 } × 100
= ( 150 ÷ 30) × 100
= 5 × 100
= 500 %
∴percentage change= 500%
