Answer:
m= -7/5
Step-by-step explanation:
(x1,y1)=(3,4)
(x2,y2)=(8, -3)
Use the slope formula:
m = y2 - y1
x2 - x1
(-3-4)/ (8-3)
= -7/5
167 multiplied by 235 would equal 39,245
Answer:
<h2>22.5 feet</h2>
Step-by-step explanation:
The formula for circumference is 2(3.14)r
So, we divide 141.3 by 6.28 and get 22.5
The radius is 22.5 feet.
Answer:
k=(5x+6)/(3x+6) and k<3/5
Step-by-step explanation:
- 3k(x+2)+2 = 5x+8
- 3k(x+2)=5x+6
- 3k=(5x+6)/(x+2)
- k=(5x+6)/(3x+6)
it is solved for k
and considering the condition for x<3:
- 3k(x+2)+2 = 5x+8
- 3kx+6k=5x+6
- (5-3k)x=6k-6
- x= (6k-6)/(5-3k)
- x<3 ⇒ (6k-6)/(5-3k)<3 ⇒ 6k-6<15-9k ⇒ 15k<9 ⇒ k<9/15 ⇒ k<3/5
So,
k=(5x+6)/(3x+6) and k<3/5
Combine like terms 2n+3n= 5n, then you subtract 7 from both sides and get 5n=-48 -48/5= -9.6
