Answer:
The result is the well-known quadratic formula: x = (-b±√(b²-4ac))/(2a)
Step-by-step explanation:
Start with the standard form quadratic equation:
ax² +bx +c = 0
1. Divide by a
x² +(b/a)x +(c/a) = 0
2. Subtract the constant
x² +(b/a)x = -(c/a)
3. Complete the square
x² +(b/a)x + (b/(2a))² = (b/(2a))²-(c/a)
(x +b/(2a))² = (b²-4ac)/(2a)²
4. Take the square root
x +b/(2a) = ±√(b²-4ac)/(2a)
5. Subtract the constant on the left to get x by itself
x = (-b±√(b²-4ac))/(2a)
Answer:
well first u have to pray. ex: "oh the holy spirit pls forgive my sins...." "I love eating cornbread" ❤❤❤❤❤❤❤❤
Ur graph.....u have a line that has a y int of -2....it has a slope of 3....it has a solid line...so there is no equal sign...it is shaded above the line, so it is greater then.....y > = 3x - 2
u have another line that has a y int of 2....it has a slope of -1/2....it has a solid line...so there is an equal sign in the problem...it is shaded below the line...so it is less then....
y < = -1/2x + 2
1/2x + y < = 2...multiply by 2
x + 2y < = 4
so ur answer is : y > = 3x - 2 and x + 2y < = 4...the 2nd one
Answer:
a. 3
Step-by-step explanation:
We solve this question gathering the information given in the question.
June serves 8 guests slices of both pies.
This is soon going to be used
June serves a total of 10 slices of apple pie
This includes the 8 guests which got served both pieces. So 10 - 8 = 2 guests were served only apple pie.
11 slices of blueberry pie.
By the same logic as above, 11 - 8 = 3 guests were served only blueberry pie.
So
8 + 2 + 3 = 13 guests were served at least one pie.
16 - 13 = 3 guests had no pie at all.
