5x^2 + 9x = -4 What is the “c” value for the following quadratic equation.

6 0

Answer:

c=4

Step-by-step explanation:

5x^2 + 9x = -4

We need to write this in the form

ax^2 +bx+c = 0

So add 4 to each side

5x^2 + 9x+4 = -4+4

5x^2 + 9x+4 = 0

a =5   b=9 and c =4

A) solve x + x + x = 54 <br>b) solve y/5 = 7<br>c) solve 4t+6=24​
egoroff_w [7]

Answer:

a) x = 18

b) y = 35

c) t = 4.5

Step-by-step explanation:

a) x + x + x = 54

3x = 54

x = 54 ÷ 3

x = 18

b) y/5 = 7

(y/5) × 5 = 7 × 5

y = 35

c) 4t + 6 = 24

4t +6 - 6 = 24 -6

4t = 18

4t ÷ 4 = 18 ÷ 4

t = 4.5

abruzzese [7]

Answer:

r=7

Step-by-step explanation:

74000=28000(1+r/12)^12(14)

divide 74000 by 28000, and cancel out 28000.

1.00580=1+r/12

(100) .06962=r

r = 6.96198

the 6 after the 9 rounds 9 to 0, which rounds the 6 to 7

r=7

A regulation baseball field measures 90 feet between each base. What is the distance around the bases in yards?
Naddika [18.5K]
Home to 1st base = 90 ft
1st base to 2nd base = 90 ft
2nd base to 3rd base = 90 ft
3rd base to home = 90 ft
so we have a total of : (90 * 4) = 360 ft

there are 3 ft in 1 yd....
so in 360 ft, there are : 360/3 = 120 yds <==

or u could just figure it between each base....90 ft = (90/3) = 30 yds per base...and u have 4 bases....so that (4 * 30) = 120 yds
