Answer:
-2/5
Step-by-step explanation:
p(x) = 5x + 2
plug p(x) = 0
5x + 2 = 0
5x = - 2
x = - 2/5
Yes I think so because she write 42 per minute the question doesn't tell you anything else.
I am not sure :(
Answer:
Step-by-step explanation:
y = x²+3
y = 3x+1
x² + 3 = 3x +1
x² - 3x + 2 = 0
(x-2)(x-1) = 0
x = 2, 1
Two solutions
(2,7) and (1,4)
Answer:
1) The length of 
is 20.
2) The length of 
is 17.
Step-by-step explanation:
1) If 
and 
, then we can use the following proportionality ratio:
(1)
Where 
is the length of segment 
.
If 
, then the value of is:
The length of is 20.
2) If 
and 
, then we can use the following proportionality ratio:
(2)
Where is the length of segment 
.
If 
, then the value of is:
The length of is 17.
