4.3 Solving 3x2+14x+16 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 3
B = 14
C = 16
Accordingly, B2 - 4AC =
196 - 192 =
4
Applying the quadratic formula :
-14 ± √ 4
x = —————
6
Can √ 4 be simplified ?
Yes! The prime factorization of 4 is
2•2
To be able to remove something from under the radical, there have to be 2 instances of it (because we are taking a square i.e. second root).
√ 4 = √ 2•2 =
± 2 • √ 1 =
± 2
So now we are looking at:
x = ( -14 ± 2) / 6
Two real solutions:
x =(-14+√4)/6=(-7+)/3= -2.000
or:
x =(-14-√4)/6=(-7-)/3= -2.667

Answer:
9/6 or 1 1/2
Step-by-step explanation:
For this problem. We need to add the following fractions:
2/3 and 5/6.
Let's find common denominators:
(Multiply 2/3 by 2/2)
= 4/6
Add the numerators:
[tex] \frac{4}{6} + \frac{5}{6} = \frac{9}{6} [/tex]
9/6 can also equal 1 1/2 as a simplified mixed fraction.

The measure of angle 1 is (3x + 10)° In the measure of angle 4 is (4x - 15)°
What is the measure of angle 7?
∠1 = ∠4 ( vertically opposite angles )
Then :-
[tex]3x + 10 = 4x - 15[/tex]
[tex]10 = 4x - 15 - 3x[/tex]
[tex]10 = 1x - 15[/tex]
[tex]1x - 15 = 10[/tex]
[tex]1x = 10 + 15[/tex]
[tex]1x = 25[/tex]
Which means :-
∠1 =
= 3x + 10
= 3 × 25 + 10
= 75 + 10
= 85°
∠4 =
= 4x - 15
= 4 × 25 - 15
= 100 - 15
= 85°
Then :-
∠7 = ∠6
∠6 + ∠4 = 180° ( interior angles on the same side of transversal )
∠6 + 85 = 180°
∠6 = 180 - 85
∠6 = 95°
As ;
∠6 = ∠7
∠7 = 95°Therefore , angle 7 = 95° .Answer:
95

The median of a set of consecutive odd integers is 138. If the greatest integer in the set is 145, what is the least integer in the set?
Answer:
131
Step-by-step explanation:
Given that:
Median of a consecutive odd integers = 138
Greatest integer In dataset = 145
Least integer in dataset =
Since the integers are consecutive ;
Number of integers to greatest integer value : Greatest integer - median value = 145 - 138 = 7
Hence, 7 integers before the median value should give us the least integer value ;
138 - 7 = 131
CHECK:
131,132,133,134,135,136,137,138,139,140,141,142,143,144,145
Median = (n+1)/2 th term
Median = (15+1)/2 = 8th term = 138
Highest = 145
Least = 131

Finn is 4 years older than Jake. Five years ago, the sum of their ages was 48.
Answer jake is 29
Step-by-step explanation:
Answer:
Step-by-step explanation:
let the age of Jake be=x
let the age of Finn be=x+4
Five years ago:
age of Jake +age of Finn=48
x+x+4-5=48
2x-1=48
2x=48=1
2x=49
x=49/2
x=24.5
therefore, age of Jake=x=24.5
therefore, age of Finn=x+4=24.5+4=28.5

Do przygotowania jednej porcji gofrow potrzeba 1 i pul szklanki maki pszennej, 1i jedna trzecia szkalanki mleka oraz 0,5 szkalnki oleju pszennego. Szklanka maki wazy 16 dag, szklanka mleka-24 dag, a szklanka oleju-21,5 dag.Ile dekagramow waza lacznie skladniki potrzeba na jedna porcje gofrow?
Odpowiedź:
5,075 dekagramu
Wyjaśnienie krok po kroku:
Biorąc pod uwagę, że:
Na jedną porcję gofra:
mąka pszenna = 1 szklanka
mleko = 1 szklanka
olej pszeniczny = 0,5 szklanki
Waga na filiżankę:
1 szklanka mąki = 16 gramów
Szklanka mleka = 24 g
Dziewczęta oliwy = 21,5 g
Na jedną porcję gofra:
(1 * 16 gramów) + (1 * 24 gramów) + (0,5 * 21,5 gramów)
16 gramów + 24 gramów + 10,75 gramów
= 50,75 grama
Odwołanie :
1 gram = 0,1 dekagramu
50,75 gramów = (50,75 * 0,1)
= 5,075 dekagramu
What is 9x-7=-7 ?????
Answer:
when we stop 9x then
7 will go another side so,.9x=7
and when X is stoppedbit will be=7/9
Answer:
[tex] \sf \: x = 0[/tex]
Step-by-step explanation:
Now we have to,
→ Find the required value of x.
The equation is,
→ 9x - 7 = -7
Then the value of x will be,
→ 9x - 7 = -7
→ 9x = -7 + 7
→ 9x = 0
→ x = 0 ÷ 9
→ [ x = 0 ]
Hence, the value of x is 0.
