Consider solving the equation below for x. 8.2 - 1 = ax + b
Which statements are true about the solution ot the equation when substituting the given values for a and b.
A If a = 8 and b=1, then there are no solution to the equation.
B
If a = 4 and b = -2, then there is no solution to the equation.
C С
If a = 8 and b = -1, then there is exactly one solution to the equation.
D
If a = 2 and b = -1, then there is exactly one solution to the equation.
E
If a = 2 and b= 4, then there is infinitely many solutions to the equation.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
