The answer to this equation is 1
Basically get two slopes -50(1)+100 will get you 1,50 (1 is x and 50 is y since its the answer)
-50(0)+100 (0,100) Y₂-Y₁/X₂-X₁ 50-100/1-0
Rate of change per month = -$50
Answer:
1. 10√3
2. -√5
3. 21√3 -9√5
4. 12√7-√11
5. 8√5-3(√5*√4) = 8√5- (3*2)√5= 2√5
6. √5*√4 -√5= 2√5-√5= √5
7. 3√5*√9 +√5*√4 -√49*√5 = 15√5+2√5-7√5= 10√5
8. √6*√4 - √6*√9 + √16*√6= 2√6-3√6+4√6= 3√6
Hope it helps you :)
