what missin
help me solve this please...
Step-by-step explanation:
(λ + 1) x² − 2x + (1 − λ) = 0
The discriminant is:
D = b² − 4ac
D = (-2)² − 4 (λ + 1) (1 − λ)
D = 4 − 4 (λ − λ² + 1 − λ)
D = 4 − 4 (1 − λ²)
D = 4 − 4 + 4λ²
D = 4λ²
Since D ≥ 0, the roots are real.
Using quadratic formula, the roots are:
x = [ -b ± √(b² − 4ac) ] / 2a
x = (2 ± 2λ) / (2(λ + 1))
x = (1 ± λ) / (λ + 1)
α, β = 1 or (1 − λ) / (λ + 1)
Therefore, the squares of the roots are:
α², β² = 1 or (1 − λ)² / (λ + 1)²
And the equation with these roots is:
(x − 1) (x − (1 − λ)² / (λ + 1)²) = 0
(x − 1) ((λ + 1)² x − (1 − λ)²) = 0
(λ + 1)² x² − (1 − λ)² x − (λ + 1)² x + (1 − λ)² = 0
(λ + 1)² x² − (1 − λ + λ + 1)² x + (1 − λ)² = 0
(λ + 1)² x² − 4x + (1 − λ)² = 0
–6x ≥ 72 solve (please help me because I'm not sure if my answer is correct or not)
My answer: x ≤ -12
Yes you are correct. You divide both sides by -6 to isolate x. Dividing both sides by a negative number will flip the inequality sign.
If you need to graph this, then you'll have a closed circle at -12 on the number line. Then you'll have shading to the left of this closed circle. The closed circle indicates "include this endpoint as part of the shaded solution set".
Answer: [tex]x\geq 12[/tex]

Answer:
£70
Step-by-step explanation:
y×0.8=56
56/0.8= 70
70×0.8=56
you're just reversing the discount :)
Answer:
70
Step-by-step explanation:
56/4=14
14=20%
56+14=70 was original price
and you can check work by multiplying 70 by .8 which gets 56

6. Given that AD= 61, CD= 61, and m< ABC= 48,
find m < CBD.
Answer:
m∠CBD=24
Step-by-step explanation:
The angle measure of m∠CBD = 24°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
AD= 61,
CD= 61,
and m∠ABC= 48°.
The diagram is given in the attached image.
Converse of Angle Bisector Theorem's
If a triangle's interior point is equally spaced from its two sides, that point will be on the angle bisector created by the two line segments.
That means,
angle measure of m∠CBD = 48/2 = 24°.
Therefore, m∠CBD = 24°.

D. Patel found the incorrect quotient and checked his work using multiplication incorrectly.
Step-by-step explanation:
The dividend is the divisor is Divide the dividend by the divisor (division by fraction means multiplication by its reciprocal):
so the quotient is 48, not
To check the answer, Patel has to multiply the quotient by the divisor to get the dividend. Check answer:
Hence, Patel found the incorrect quotient and checked his work using multiplication incorrectly.

The Division of (7/3) ÷ (2/9) gives 21/2.
What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
Divide 7/3 by 2/9
So, (7/3) ÷ (2/9)
= 7/3 x 9/2
= 7 x 3/2
= 21/2
Hence, the division results to 21/2.

find the area of the circle r=14m use pi=3.14 and round your answer to the nearest hundredth
Answer:
The answer is 615 m²Step-by-step explanation:
Area of a circle = πr²
where
r is the radius
From the question
r = 14 m
π = 3.14
The area of the circle is
A = 3.14 × ( 14 ) ²
= 3.14 × 196

In a poll, 44% of the voters say they plan to reelect the mayor. The poll has a margin of error of ±3 percentage points. Use a model to write and solve an absolute value inequality to find the least and greatest percents of voters who plan to reelect the mayor. Response - correct |x−3|≤44 |x−3|≥44 |x−44|≤3 |x−44|≥3 Question 2 The least percent of voters who will vote for the new mayor is %. The greatest percent of voters who will vote for the new mayor is %.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Percentage of voters who plan to re-elect mayor = 44%
Margin of Error in measurement = ±3 % points
The absolute value inequality to find the lowest and greatest percent of points :
X = mid value
44% = estimated percentage
≤3 = error margin
Hence,
|mid value - estimate| ≤ error margin
|x−44|≤3
Hence,
-3 ≤ x - 44 ≤ +3
-3 + 44 ≤ x ≤ 3 + 44
41 ≤ x ≤ 47
Hence,
Least percentage point = 41
Greatesr percentage point = 47
