Using a graphing utility, find the exact solutions of the system. round to the nearest hundredth and choose a solution to the system from the choices below.
y = x² + 3x
y = 2x + 5

(0,4)
(2.79, 0.58)
(1.79, 8.58)
(-0.58, -2.79)

Part 1) The exact solutions are

  and  

Part 2) (1.79, 8.58)

Step-by-step explanation:

we have

----> equation A

----> equation B

we know that

When solving the system of equations by graphing, the solution of the system is the intersection points both graphs

Find the exact solutions of the system

equate equation A and equation B

The formula to solve a quadratic equation of the form

is equal to

in this problem we have

so

substitute in the formula

so

The solutions are

Find the values of y

First solution

For

The first solution is the point

Second solution

For

The second solution is the point

Round to the nearest hundredth

First solution

see the attached figure to better understand the problem

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
