The sign of the term in x^2 is negative  so the graph will open downwards.
when x = 0 y = 1
The coordinates of the vertex are (0,1)
the maximum value of the function is 1
and the axis of symmetry ix x = 0 (  the y axis)

Pratap Puri rowed 14 miles down a river in 2 ​hours, but the return trip took him 3 and one half hours. Find the rate Pratap can
SOVA2 [1]

speed of current is 1.5 mi/hr

Answer:

let the rate in still water be x and rate of the current be y.

speed down the river is:

speed=distance/time

speed=14/2=7 mi/h

speed up the river is:

speed=(14)/(3.5)=4 mi/hr

thus total speed downstream and upstream will be:

x+y=7...i

x-y=4.......ii

adding the above equations i and ii we get:

2x=11

x=5.5 mi/hr

thus

y=5-5.5=1.5 mi/r

thus the speed in still waters is 5.5 mi/hr

speed of current is 1.5 mi/hr

Write your own two equations that would have a solution of (3, 6).
andrey2020 [161]

Answer:

y = 2x

y = 3x - 3

Step-by-step explanation:

Hi,

<u>y = 2x</u>

<u>6 = 2(3)</u>

<u>6 = 6</u>

<u>That's a solution</u>

<u>y = 3x - 3</u>

<u>6 = 3(3) - 3</u>

<u>6 = 9 - 3</u>

<u>6 = 6</u>

<u>That's a solution</u>

Hope this helps :)
