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.

Tony bought 255 1-inch nails and 5 boxes of 2-inch nails. Each box of 2-inch nails had equal amounts of nails in them. He bought a total of 620 nails. Find the number of nails in each box of 2-inch nails.
Answer:
73 nails
Step-by-step explanation:
Number of 1 inch = 255
Boxes of 2 - inch = 5
Each box of 2 _inch has equal amount of nails
Total number of nails = 620
Number of nails in each box of 2_inch nails:
Let Number of nails in each box = b
Number of 1_inch + 5 * number of 2_inch = 620
255 + 5b = 620
5b = 620 - 255
5b = 365
5b / 5 = 365 / 5
b = 73
Hence, there are 73 nails in each box of 2_inch nails
Which property of equality could be used to solve -3x = 348? addition property A.subtraction property B.division property C.multiplication property
Answer:
Division property
Step-by-step explanation:
you would need to set up your equation. Then divide -3x by -3 to get x alone. then you do 348 divided by -3 to get your answer
-3x=348
-3= -3
x=-116

The table of values shows the height of a car of a Ferris wheel as it travels in a circular motion.
Which statements are true?
Select each correct answer.
~ The car makes a complete revolution in 8 s.
~ The radius of the Ferris wheel is 26 m.
~ If the car is loaded at 0 s, then people are loaded at the lowest height of the Ferris wheel.
~ The maximum height of the Ferris wheel above ground is 40 m.
Answer:
bruh if your question is
"What is the maximum height of the Ferris wheel? "
its 80m
Step-by-step explanation:
ive looked for the question nd couldnt find it so i sarcificed my grade for yall, welcome
The values of the Ferris wheel.
The Ferris wheel is a ride that is fired by the upright rotating wheel and is able of carrying multiple passengers. The table shows us the value of the height of a car of the Ferris wheel and as it travels in a circular motion. The time and height of the second and meters are given.
Thus the answer is if the car is loaded at 0 s, then people are at the lowest part.
The wheel data shows that in 2 seconds the height of the wheel is about 26 meters and in 16 seconds the height of the wheel is about 6 meters. Thus the car is located at 0s and people are at the lowest height of the wheel.Hence the option C is correct.Learn more about the height of a car.

Determime if the following lines are paraleel, perpendicular or neither.
the value of y varies directly with x. when y = 7.5, x = 5. what is the value of y when x = 80?.
Answer:
Step-by-step explanation:
120 = y. the ratio is 3:2
80/2 is 40
40 times 3 is 120
120:80 = 3:2
x + 2x + 12y + 4 I don't know the answer can someone help me please
Answer:
The asnwer is 3x + 12y + 4
Answer:
I think you wrote it wrong but if not here
Step-by-step explanation:
Simplifying
2x + -12y = 4
Solving
2x + -12y = 4
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12y' to each side of the equation.
2x + -12y + 12y = 4 + 12y
Combine like terms: -12y + 12y = 0
2x + 0 = 4 + 12y
2x = 4 + 12y
Divide each side by '2'.
x = 2 + 6y
Simplifying
x = 2 + 6y

1) Albert has $200 in the bank. He would like to save $50 every month to buy Christmas
gifts. Which equation can be used to find y, the amount Albert will save for x days?
y = 50x + 200
y = 50 + 200x
y = 250x
y = 200 + 250x
Answer:
y = 50x + 200
Step-by-step explanation:
He has $200 at the bank. He is then adding 50 per month (that's why its 50x).

Answer:
A) 29/40
Step-by-step explanation:
The formula for this is ...
P(A or B) = P(A) + P(B) - P(A and B)
Filling in the given values, you have ...
P(A or B) = 9/20 +1/2 - 9/40
P(A or B) = 18/40 +20/40 -9/40 = (18+20-9)/40
P(A or B) = 29/40 . . . . matches choice A
