Choose the pair(s) of integers that can be substituted into the equation ax2 - 6x + c = 0 so that it has two real solutions.
Maksim231197 [3]

The options are not provided, but method is stated below

Answer:

Quadratic equation ax2 - 6x + c = 0

options would be given for a and c

  1. substitute a and c
  2. check for Discriminant
  3.  b^2 - 4ac \geq  0
  4. 36 -4ac \geq 0

These conditions will fetch us the result required among the options.

Note : the \geq sign will give us the result for Two real unequal solutions and two real equal solutions.  If we only need Real unequal solutions we only use > sign instead of \geq

Solve for x.<br><br> 5/6 x = 10/3<br><br> x = 4/3<br><br> x = 2<br><br> x = 25/9<br><br> x = 4
SashulF [63]

Answer: LAST OPTION.

Step-by-step explanation:

In order to solve for the variable "x" from the expression \frac{5}{6}x=\frac{10}{3}, you need to follow these steps:

1) You need to multiply both sides of the equation by 3:

3(\frac{5}{6}x)=(\frac{10}{3})(3)\\\\\frac{15}{6}x=10

2)  You need to multiply both sides of the equation by 6:

(6)(\frac{15}{6}x)=(10)(6)\\\\15x=60

3) Finally, you can divide both sides of the equation by 15:

\frac{15x}{15}=\frac{60}{15}\\\\x=4
