Answer:
7y²
Step-by-step explanation:
First u group them like 4+3+y+y=7y²
Let 'x' be the distance from THE far bank where 700 is the distance to the NEAR bank
boat one has travelled 700 (rate = 700/unit time) boat two has travelled x rate = x / unit time
boat one then travels x + 400 more and boat two travels 700 + (700+x -400) more when they meet
The time is the same rate x time = distance distance/rate = time equate the distances divided by the respective rates
(700 + x + 400)/700 = ( x + 700 + (700+x-400) )/x
1100x + x^2 = 1400x + 700000
x^2-300x -700000 = 0 quadratic formula yields x = 1000
One boat travels 700 the other 1000 whe they first meet.....width of river = 700+ 1000 = 1700 m
Answer:
Jace gets $18.00 while Chris keeps $27.00
Step-by-step explanation:
Jace
2/5 of $45.00
2/5 × 45
= $18.00
Jace gets $18.00
Chris:
$45.00 - $18.00 = $27.00
Answer:
There are none.
Step-by-step explanation:
<u>No calculus involved:</u>
The line, in slope-intercept form, has equation 
, ie is always decreasing (easy to spot applying the definition)
Meanwhile, 
is always increasing over its domain.
At no point the tangent will be decreasing.
<u>Let's use calculus</u>
We are to solve the equation 
which has no real solutions.
