For what values of m are there 2 different distinct real solutions? Give your answer as an inequality. X^2-2x+m.
I'm not sure, but I think the formula is b^2-4ac>0
Answer:
m<1
Step-by-step explanation:
If the expression is in the form of [tex]ax^2+bx+c[/tex], then the condition for having 2 different real roots is
[tex]b^2-4ac>0\cdots(i)[/tex].
The given expression is [tex]x^2-2x+m[/tex].
Here, a=1, b=-2 and c=m.
So, by using equation (i),
[tex](-2)^2-4(1)(m)>0[/tex]
[tex]\Rightarrow 4-4m>0[/tex]
[tex]\Rightarrow 4m<4[/tex]
[tex]\Rightarrow m<4/4[/tex]
[tex]\Rightarrow m<1[/tex].
Hence, the condition for the expression [tex]x^2-2x+m[/tex] to have two different real roots is m<1.

Answer:
Step-by-step explanation:
Like terms have the same variables and powers.
1). 6b and [tex]\frac{b}{2}[/tex] = [tex]\frac{1}{2}b[/tex]
5x² and x²
2). 12a² and 4a²
4x³ and 3.5x³
b and [tex]\frac{5}{6} b[/tex]
3). 8x
4). 5a² + 16
5). There are no like terms there.
6). 6b + 5n + 6b + 5n = 12b + 10n
-x + 5 + 6x = 1 + 5x + 3
Answer:
There are no values of
x
that make the equation true.
No solution
Step-by-step explanation:
-x + 5 + 6x = 1 + 5x + 3
Group like terms
-x+6x+5=1+5x+3
Add similar elements:-x+6x=5x
5x+5=1+5x+3
Group like terms
5x+5=5x+1+3
Add the numbers 1+3=4
5x+5=5x+4
Subtract 5 from both sides
5x+5-5=5x+4-5
Simplify
5x=5x-1
Subtract 5x from both sides
5x-5x=5x-1-5x
Simplify
0=-1
The sides are not equal
No Solution
Kaley and Tom both work at Publix as cashiers for $7.68 per hour. This week Kaley worked 5 more hours than Tom in overtime. Write an expression that represents the weeks' total wages for Kaley and Tom if h represents the number of hours Tom worked.
Answer:
7.68h
38.4 + 7.68h
Step-by-step explanation:
Earnings per hour = $7.68
This week Kaley worked 5 more hours than Tom in overtime
h = number of hours Tom worked.
Tom's total earnings for the week = earnings per hour × number of hours
= $7.68 × h
= 7.68h
Tom's total earnings for the week = 7.68h
Kayley's total earnings for the week = earnings per hour × number of hours
He works 5 hours more than Tom in overtime.
Tom = h
Kayley = 5 + h
Kayley's total earnings for the week = earnings per hour × number of hours
= (7.68) × (5 + h)
= 38.4 + 7.68h
Kayley's total earnings for the week =
38.4 + 7.68h
Two marathon runners run the full distance of the marathon, approximately 26 miles, in 4 hours.
Part A
About how many miles did they run in 1 hour?
Enter the correct answer in the box. Part B
What percent of the full distance have they run in 1 hour?
Enter the correct answer in the box.
Answer:
6.5 miles in 1 hour and they will run 75% of the full distance in 1 hour.
Step-by-step explanation:
The distance covered by two marathon runners = 26 miles
They takes 4 hours
We need to find how many miles did they run in 1 hour
In 4 hour, the distance covered is 26 miles
To find distance covered in 1 hour, divide 26 by 4 such that.
[tex]d=\dfrac{26}{4}\\\\d=6.5\ \text{miles/hour}[/tex]
So, they will cover 6.5 miles in 1 hour.
For percentage,
[tex]\%=\dfrac{26-6.5}{26}\times 100\\\\=75\%[/tex]
So, they will run 75% of the full distance in 1 hour.
Anne's potato salad recipe requires one pound of potatoes for every four people served. How many pounds of potatoes will Anne need to serve 14 people at her picnic?
Answer:
3.5 pounds for 14 people
Step-by-step explanation:
Given
1 pound = 4 people
Required
Determine the pounds for 14 people
Represent this with x; so, we have:
[tex]1\ pound = 4\ people[/tex]
[tex]x = 14\ people[/tex]
Cross Multiply
[tex]x * 4 = 1 * 14[/tex]
[tex]4x = 14[/tex]
Solve for x
[tex]x = 14/4[/tex]
[tex]x = 3.5[/tex]
Hence, 3.5 pounds for 14 people

At the candy shop, Ameenah sells chocolate covered raisins, c, for $1.50 per pound, and peanuts, p, for $1.20 per pound. Ameenah wants to make 20 pounds of a mixture of raisins and peanuts that sells for $1.35 a pound. How many pounds of each should she use?
Thanks! :)
Answer:
10 pounds of raisins and 10 pounds of peanuts.
Step-by-step explanation:
Let c represent the pounds of chocolate covered raisins.
Let p represent the pounds of peanuts.
We know that the raisins cost $1.50 per pound and the peanuts cost $1.20 per pound.
Ameenah wants to make 20 pounds of a mixture of the raisins and peanuts that sells for 1.35 a pound. So, we can write the following expression:
[tex]1.5c+1.2p[/tex]
This represents the cost given c pounds of raisins and p pounds of peanuts.
Ameenah wants to combine c and p to make them 1.35 per pound. In other words, the expression must equal:
[tex]1.5c+1.2p=1.35(c+p)[/tex]
We also know that she wants to make 20 pounds. So, c plus p must total 20. Therefore:
[tex]c+p=20[/tex]
We now have the system of equations:
[tex]\left\{ \begin{array}{ll} 1.5c+1.2p=1.35(c+p) \\ c+p=20\end{array}[/tex]
First, since we know that c+p is 20, we can substitute that into the first equation.
Second, let's subtract p from both side for the second equation to isolate a variable. So:
[tex]c=20-p[/tex]
Let's now substitute this into the first equation:
[tex]1.5(20-p)+1.2p=1.35(20)[/tex]
Distribute:
[tex]30-1.5p+1.2p=27[/tex]
Combine like terms:
[tex]-0.3p+30=27[/tex]
Subtract 30 from both sides:
[tex]-0.3p=-3[/tex]
Divide both sides by -0.3. So, the amount of peanuts needed is:
[tex]p=10[/tex]
10 pounds of peanuts is needed.
This means that 20-10 or 10 pounds of raisins is needed.
Answer:
10 pounds of both raisins and peanuts.

Triangle CDA is the image of triangle ABC after a 1800 rotation around the midpoint of segment AC. Triangle ECB is the image of triangle ABC after a 1800 rotation around the midpoint of segment BC.
Explain why ABCD and ABEC are parallelograms.
Identify at least two pairs of congruent angles in the figure and explain how you know they are congruent.
Explain how to use what you know about the sum of the angles in a triangle to figure out the sum of the angles of quadrilateral ABED.
1. they both have 2 different congruent sides
2. angles ACD and BEC, since they are the same triangles, and are at congruent ends
3. since they are all the same triangle and has just been rotated some, you can figure out that it is the same triangle. once you figure out the angles for one of the triangles, you can figure outit for the other 2 since they are all congruent.

Answer:
V/3k = t
Step-by-step explanation:
Isolate the variable (t)
V = 3k/t
We have to get rid of 3 and k to isolate t
Since 3 and k are part of a fraction we can multiply it by their reciprocal
V = 3k/t × 1/3k
What we do to one side, we must do to the other
V × 1/3k = 3k/t × 1/3k
The reciprocals equals 1
V × 1/3k = t × 1
Any number or variable multiplied by 1 equals itself (applies to both sides of the equation)
V/3k = t

Show your work: Solve for b, where A is the area of a rectangle, b is the length of the base of the rectangle, and h is the height of the rectangle. Ab h
Answer:
[tex]b = \dfrac{A}{h}[/tex]
Step-by-step explanation:
Given the formula for calculating the area of the rectangle as;
A = bh where;
b is the length of the base of the rectangle, and;
h is the height of the rectangle
Required
Make b the subject of the formula
Given
[tex]A = bh\\\\divide \ both \ sides \ by \ h\\\dfrac{A}{h} = \dfrac{bh}{h}\\ \dfrac{A}{h} = b\\Re-arrange;\\b = \dfrac{A}{h}[/tex]
Hence the value of b in terms of A and h is expressed as [tex]b = \dfrac{A}{h}[/tex]

Answer: Image #1: C. Distributuve Property Image #2: A. n + 2(7)
Step-by-step explanation: For Image #1, they used the Distributive Property because the number 3 was (distributed) and multiplied to both x and 7. The equation is saying that 3x + 21 = 42, and that we’re trying to solve for x. For Image #2, the answer is A. n + 2(7) because after you solve the expression, the answer would be 14n. When you look at the four options, (A. B. C. D.), letter A. would be the answer because it equals to 14n.
