The value of 'm' for which the equation (1+m) x²-2(1+3m) x +(1+8m) =0 has equal roots, is Х
We know –
If Δ (Discriminant) >0here are two separate real roots.If Δ (Discriminant) =0, there are two identical real roots.If Δ (Discriminant) <0, there are no real roots, but there are two complex roots.Question's given –
The equation (1+m) x²-2(1+3m) x +(1+8m) =0 has equal roots.That means, Δ Discriminant is 0.(D= b²-4ac)
According to the question –
a = (1+m)b = -2(1+3m)c = (1+8m)Now, Δ Discriminant = 0
↠{-2(1+3m)}² -4 × (1+m) ×(1+8m)=0
↠4(1+3m)² - 4 (1+m)(1+8m) = 0
↠4(1+ 9m² + 6m - 1 -8m - m -8m²) =0
↠4 (1+ 9m² + 6m - 1 -9m -8m²)=0
↠m²-3m =0
↠m(m-3) = 0
↠m =0,3
Henceforth, value of m will be 0 or 3.can someone please help me with this geometry question I will mark brainliest

Answer:
14b.) RS = 60; ST = 36; RT = 96
Step-by-step explanation:
Since you have correctly solved for y = 7, all you need to do for b is to plug in y.
RS = 8(7) + 4 = 60
ST = 4(7) + 8 = 46
(You can add RS and ST or plug in for y for RT)
RT = 15(7) - 9 = 96
Please help with this ASAP.
Answer: Choice D
Explanation:
I'll use the point-slope form to get the following
[tex]y - y_1 = m(x - x_1)\\\\y - 1 = \frac{3}{4}(x - (-4))\\\\y - 1 = \frac{3}{4}(x + 4)\\\\y - 1 = \frac{3}{4}x + \frac{3}{4}*4\\\\y - 1 = \frac{3}{4}x + 3\\\\y = \frac{3}{4}x + 3 + 1\\\\y = \frac{3}{4}x + 4 \ \ \text{... matches with choice D}\\\\[/tex]
You should find that plugging x = -4 into equation D will lead to y = 1 as a way to confirm the answer.
Answer:
D
Step-by-step explanation:
m = 3/4
point: (-4, 1)
We can use the slope-intercept form. We know one point, so we can use its coordinates for x and y. We also know the slope, so we use the slope for m. Then we solve for b.
y = mx + b
Substitute m with the slope.
y = (3/4)x + b
Use the x-coordinate of the given point for x and the y-coordinate of the given point for y.
1 = (3/4)(-4) + b
Solve for b.
1 = -3 + b
b = 4
Now that we know the value of b, we can write the equation of the line.
y = mx + b; m = 3/4; b = 4
y = 3/4 x + 4
Answer: D
Comparing the two ratios 2/4 and 1/2
2/4 is larger
Answer:
3.5 : 7 > 1.2 : 2.5.
Step-by-step explanation:
1. Compare the ratios 4 : 5 and 2 : 3.
Solution:
Express the given ratios as fraction
4 : 5 = 4/5 and 2 : 3 =2/3
Now find the L.C.M (least common multiple) of 5 and 3
The L.C.M (least common multiple) of 5 and 3 is 15.
Making the denominator of each fraction equal to 15, we have
4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15
Clearly, 12 > 10
Now, 12/15 > 10/15
Therefore, 4 : 5 > 2 : 3.
2. Compare the ratios 5 : 6 and 7 : 9.
Solution:
Express the given ratios as fraction
5 : 6 = 5/6 and 7 : 9 =7/9
Now find the L.C.M (least common multiple) of 6 and 9
The L.C.M (least common multiple) of 6 and 9 is 18.
Making the denominator of each fraction equal to 18, we have
5/6 = (5 ×3)/(6 ×3) = 15/18 and 7/9 = (7 ×2)/(9 ×2) = 14/18
Clearly, 15 > 14
Now, 15/18 > 14/18
Therefore, 5 : 6 > 7 : 9.
3. Compare the ratios 1.2 : 2.5 and 3.5 : 7.
Solution:
1.2 : 2.5 = 1.2/2.5 and 3.5 : 7 =3.5/7
1.2/2.5 = (1.2 ×10)/(2.5 ×10 ) = 12/25 and 3.5/7 = (3.5 ×10)/(7 ×10) = 35/70 = 1/2
[We removed the decimal point from the ratios now, we will compare the ratio]
Now find the L.C.M (least common multiple) of 25 and 2
The L.C.M (least common multiple) of 25 and 2 is 50.
Making the denominator of each fraction equal to 50, we have
= 12/25 = (12 ×2)/(25 ×2) = 24/50 and 1/2 = (1 ×25)/(2 ×25) = 25/50
Now, 25/50 > 24/50
Therefore, 3.5 : 7 > 1.2 : 2.5.
What is the value of x? Then determine the measure of each angle.
Answer:
x = 14° || each angle has 108°
explanation:
first we need to find the total interior angle of this shape:
formula: ( n - 2 ) * 180 ..............where n is the number of sides
( 5 -2 ) * 180
540°
if all sides in the shape are equal, they must have same angle of 9x -18
5 ( 9x -18 ) = 540°
9x -18° = 108°
9x = 108° + 18°
9x = 126°
x = 14°
So each angle has: 9x - 18
9(14) - 18
108°
The water jug for a basketball team was 7/8 full of water after the game the 8 players poured out 3/5 of the water in the jug. How much water is still there
The water left in the jug after the players poured out some water is 11/40
How to subtract fractionQuantity of water in the jug = 7/8Water poured out of the jug = 3/5Water remaining = Quantity of water in the jug - Water poured out of the jug
= 7/8 - 3/5
= (35-24) / 40
= 11/40
Therefore, the water still left in the jug us 11/40

What is 2.58333333333 as a fraction?
Answer:
2 583/1000
Step-by-step explanation:
Answer
To write 2.58333333333 as a fraction you have to write 2.58333333333 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
2.58333333333 = 2.58333333333/1 = 25.8333333333/10 = 258.333333333/100 = 2583.33333333/1000 = 25833.3333333/10000 = 258333.333333/100000 = 2583333.33333/1000000 = 25833333.3333/10000000 = 258333333.333/100000000 = 2583333333.33/1000000000 = 25833333333.3/10000000000 = 258333333333/100000000000

Answer:
angle x= 136
Step-by-step explanation:
angle on straight line =180
so we do 180 - 96 (angle y)=84
then:
angles in a triangle add up to 180
we do
84 (inside the triangle next to angle y) + 52 (angle z)= 136
180 (all angles in triangle) - 136 (angle y and z)=44
Now we know that the angle inside the triangle next to Angle x is 44
Angles on straight line =180
180-44= 136
angle x = 136Answer:
Step-by-step explanation:
triangle first:
= y=96
= z=52
= so , 180-96=84
= so, angle b = 84
= the corresponding side should be equal so, angle c = 84
= so x. = 180 - 84
= x = 96
= so , x = 96
so , this is the triangle theory yehhaaaaa

-4x+3y=-4 x-2y = 1 +
this is substitution I really need help
Answer:
x = 1
y = 0
Step-by-step explanation:
You did a great job solving one of the equations for a single variable. You solved for x. But what your paper shows is that...it jind of looks like you were going to substitute the 2y+1 into y. BUT you need to substitute it into x.
-4x + 3y = -4
x = 2y + 1
Fill in 2y + 1 into x in the first equation.
-4(2y+1) + 3y = -4
Now you have an equation in one variable. There are only y's in this equation. Next, distribute.
-8y - 4 + 3y = -4
combine like terms.
-5y - 4 = -4
add 4 to both sides.
-5y = 0
divide by -5
y = 0
It's okay that it cam out to be zero. Its fine!
y=0
Put it back in one of the original equations to find x.
x = 2y + 1
x = 2(0) + 1
x = 1
The solution is
x=1
y=0
You can write this as an ordered pair.

Suppose that paulie and vinny each can produce ice cream or t-shirts. The table shows the quantity of each good that paulie and vinny each can produce in 1 hour, respectively, if they devote all of their time and effort into making the good. Round all answers to two decimal places.
Paulie's opportunity cost of producing a cup of ice cream is 4 T-shirts while Vinny's opportunity cost (C) of producing a t-shirt is 0.53
How to calculate the opportunity costThe table entries are given as:
Ice Cream (cups) T-shirts (quantity)
Paulie 5.00 20.00
Vinny 8.00 15.00
Paulie's opportunity cost of producing a cup of ice cream is calculated by dividing the number of T-shirts by the cups of ice cream.
So, we have:
[tex]C = \frac{20.00}{5.00}[/tex]
[tex]C =4.00[/tex]
Similarly, Vinny's opportunity cost (C) of producing a t-shirt is calculated by dividing the cups of ice cream by the number of T-shirts
So, we have:
[tex]C = \frac{8.00}{15.00}[/tex]
[tex]C = 0.53[/tex]
Hence, Vinny's opportunity cost (C) of producing a t-shirt is 0.53

Sqaure has a side let say p = 3x + 12
As the formula for square area is
Area = A = p² or length × width
As square has all equal side
So ( 3x + 12 ) ( 3x + 12 )
⇒ 9x² + 36x +36x + 144
