//Question number 1//
When graphing an inequality there are certain things to keep in mind that make it different from an equation of a line.
Here are some of them:
*You must look out to see whether it will be dashed or solid
*You must know which side of the graph to shade it in
*If they are not in standard form, you have to change them into standard form (THIS ONE MIGHT ACTUALLY APPLY TO A REGULAR EQUATION)
----Basically, the main difference is that in a "normal equation" you have an equal sign while in an inequality you have inequality signs (≤, ≥, <, >)----
//Question Number 2//
------ When using ≤ or ≥ (where they have half the equal sign at the bottom) the line for the inequality would be solid
------ When using < or > (where there is no equal sign- just the inequality sign) the line for the inequality would be dashed

For
the discriminant is
there are 3 basic cases of what happens for different discriminants
1. if the discriminant is less than 0, then there are no real zeroes
2. if the discriminant is 0, then it has 1 zero
3. if the discriminant is greater than 0, it has 2 zeroes
so given
a=3,b=-7,c=4
thus the discriminant is
the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0
the answer is the equation has two zeroes because the discriminant is greater than 0

Answer:
2.4
Step-by-step explanation:
You have to divide 6.4 by 2.4 to get 2.66666666667.
Then you multiply 2.66666666667 and 0.9 to get 2.4
When x = 6.4, y = 2.4
Hope this helps!
Answer: 25/3
Step-by-step explanation: 8/8•3=24/8 then add 24/8 + the 1/8 = 25/8.
