The discriminant of a quadratic equation is 16. Which number represents the number of real solutions to the equation?
0
3
Answer:
The
number 2
Step-by-step explanation:
What we need here is just the sign of the discriminant
From the question in this case, the discriminant is positive
Thus, whenever we have a positive discriminant, then the number of real solution is 2 and these two are distinct (different from one another).
Which inequality describes all the solutions to -5x + 6 < 2(-3 − x)?
Answer: x>4
Step-by-step explanation:
The solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.
The given inequality is 5x + 6 < 2(-3 - x).
What is a inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality can solved as follows:
5x + 6 < 2(-3 - x)
Multiply 2 to the bracket
5x + 6 < -6 - 2x
Add 2x to both the sides of inequality
5x + 6 + 2x < -6 - 2x + 2x
⇒7x+6<-6
Subtract 6 to both the sides of inequality
7x+6-6<-6-6
⇒7x<-12
Divide 7 to both the sides of inequality
7x/7<-12/7
⇒x<-12/7
⇒x<-1.7
Solution set = {-2, -3, -4, -5, -6,.......}
Therefore, the solution set for the given inequality is {-2, -3, -4, -5, -6,.......}.

Solve for x.
12x - 4 = 4(2x + 1)
Answer:
X = 2
Step-by-step explanation:
12x - 4 = 4(2x + 1) (multiple 2x and 1 by 4)
=> 12x - 4 = 8x + 4
=> 12x - 8x = 4+4 (and the alike terms together)
=> 4x = 8
=> x = 8/4 ( divide 8 and 4 by 4)
=> x = 2/1
=> x = 2

Farmer Bill sold potatoes at the farm market. He sold a quarter to the first person, 4/9 of what was left to the second person, and the third buyer bought 4/5 of what was left and the last 10 lb. How many pounds of potatoes did farmer Bill sell?
Answer:
Farmer Bill sold 120 lb of potatoes
Step-by-step explanation:
Suppose farmer Bill had x lb of potatoes. He sold a quarter to the first person. A quarter is written as (1/4)x. After that, Bill had x-(1/4)x = (3/4)x.
Then he sold 4/9 of what was left to the second person, thus it was left 1-4/9=5/9 of the remaining potatoes. Multiplying both factors:
[tex]\frac{5}{9}*\frac{3}{4}x=\frac{5}{12}x[/tex]
This is the remaining portion of the potatoes.
Finally, he sold 4/5 of it and the last 10 lb. This means 1 - 4/5 = 1/5 of the remaining is equivalent to 10 lb:
[tex]\frac{1}{5}*\frac{5}{12}x=\frac{1}{12}x[/tex]
Thus:
[tex]\frac{1}{12}x=10[/tex]
x = 120 lb
Farmer Bill sold 120 lb of potatoes
The Farmer will sold 120 lb of potatoes.
Let us consider that farmer have x lb of potatoes.
He sold a quarter to the first person, that is [tex]\frac{x}{4}[/tex]
Potatoes left,[tex]=x-\frac{x}{4} =\frac{3x}{4}[/tex]
4/9 of what was left to the second person,
Potatoes sell to second person is, [tex]\frac{3x}{4} *\frac{4}{9} =\frac{x}{3}[/tex]
the third buyer bought 4/5 of what was left
that is, [tex]\frac{4}{5}*(\frac{3x}{4} -\frac{x}{3} ) =\frac{x}{3}[/tex]
Potatoes left [tex]=\frac{5x}{12} -\frac{x}{3} =\frac{x}{12}[/tex]
Since, Potatoes left = 10 lb
So, [tex]\frac{x}{12} =10\\\\x=12*10=120[/tex]
Thus, The Farmer will sold 120 lb of potatoes.
