Answer:

Option C - (0,1), (-5/2,6)

Step-by-step explanation:

Given : The system of equations y=2x^2+3x+1 and y=-2x+1

To find : Solve the system by graphing ?

Solution :

Let the equation 1 - y=2x^2+3x+1  is a quadratic equation.

Equation 2 - y=-2x+1 is a linear equation.

Plot these equation in the graphing tool,

Equation 1 y=2x^2+3x+1  is shown by blue line with vertex (-0.75,-0.125).

Equation 2  y=-2x+1  is shown by green line passing through (0.5,0) and (0,1).

The intersection point of the equations is the solution of the system i.e. (-2.5,6) and (0,1).

The solution is (0,1), (-5/2,6).

Refer the attached figure below.

Therefore, Option C is correct.

Alja [10]

I believe it'd be -x - 18 you'd add the 12x and 2x and get 14x-15x and get -x then you'd combine the -15 and -3 to get -18.

A library is open til' 5:00 P.M. On Wednesdays, the library closes 2 hours early. How many hours for a month is the library open
svet-max [94.6K]
So
if you assume that the month has 30 days and that the library opens at midnight, then
24 hours in a day
5 pm=12+5=17 hours
on wednessday=17-2=15 hours
wednessday=1/7 of week
so we find 1/7 of 30 which is 30/7=4 and 2/7
then subtract that from 30
30-4 and 2/7=25 and 5/7

ok so then we have
25 and 5/7 days is 17 hours and
4 and 2/7 days is 15 hours
so just multipy them and add

25 and 5/7 times 17=437.143 hours
4 and 2/7 days times 15 =64.2857
add

437.143+64.2856=501.429
so aprox 501.429

the real equation is  [(\frac{1}{7})(n)(15)]+[ (\frac{6}{7}) (n)(17)]=hours where n represents the number of days in the month

apros 501.429
