The other solution to the equation is -3.
Step-by-step explanation:
Given equation is;
5x²+bx+12=0
One solution is -4/5
We will put this solution in Eqn to get the value of b first,
Multiplying each term by 5
Dividing both sides by -4
Putting b=19 in given Eqn
5x²+19x+12=0
Here,
a=5 , b=19 , c=12
Using quadratic formula,
Either, or,
The other solution to the equation is -3.

Answer:
Part 1)
Part 2) The equation satisfy the set of coordinates (see the explanation)
Step-by-step explanation:
step 1
Find the linear equation
The rule for the linear equation states that y is three more than twice x.
so
The variable y is equal to the number 2 multiplied by x plus the number 3
step 2
Prove that the equation satisfies the set of coordinates
substitute the value of x and the value of y in the linear equation and then compare the results
a) (-1, 1)
----> is true
so
The equation satisfy the ordered pair
b) (0, 3)
----> is true
so
The equation satisfy the ordered pair
c) (-1/3,7/3)
----> is true
so
The equation satisfy the ordered pair
therefore
The equation satisfy the set of coordinates
