The standard form of a quadratic equation is Ax^2 + Bx + C = 0. So for –6 = x^2 + 4x – 1 to be in its standard form, we can move -6 to the other side of the equation and have x^2 + 4x + (-1 +6) = 0 x^2 + 4x + 5 = 0 So, from the standard form, the value of of C is 5<span>.</span>

Answer:

concluzionăm că nu există o ecuație care să poată justifica valoarea x = 3 din opțiunile de mai sus după rezolvarea lor

Step-by-step explanation:

Urmează să aflăm din cele trei opțiuni date, care este una dintre opțiuni care rezultă în x = 3

Să rezolvăm opțiunea una după cealaltă pentru a deduce și determina care este răspunsul corect și corect.

a) -2*x + 3 = 9

-2x = 9 -3

-2x = 6

Împărțiți ambele părți la -2

x = 6/-2

x = -3

b) -4*x +5 = 7

-4x = 7 -5

-4x = 2

Împărțiți ambele părți la -4

x = \dfrac{2}{-4} \\ \\  \\ x= \dfrac{1}{-2}

c) \dfrac{1}{3}*x -8 =9

\dfrac{1}{3}x = 9 +8

\dfrac{1}{3}x =17

Înmulțiți ambele părți cu 3

x =17*3

x = 51

Prin urmare; concluzionăm că nu există o ecuație care să justifice valoarea x = 3 din opțiunile de mai sus după rezolvarea lor

On a coordinate plane, polygon GHIJ translates 8 units to the left to form polygon G'H'I'J'. Which of the following equations is
lana66690 [7]
A. True. This is because distances are preserved and kept the same. 

B. True. Moving any point to it's corresponding image is having you travel 8 units.

C. True. Corresponding angles are congruent. 

D. False. This is not always true so in general it's false. 

The final answer is choice D

makvit [3.9K]

Answer:

The answer is D

Step-by-step explanation:

\frac{4}{5} = 0.8

\sqrt{7} = 2.64

2.64 > 0.8 because 2 is a whole number while 0.8 is a decimal

Starting from 300 feet away, a car drives toward you. It then passes by you at a speed of 48 feet per second. The distance dd (i
deff fn [24]
The answer to this question would be: 5 second

In this question, you are given the initial distance (300ft), car velocity(48ft/s) and the final distance(60ft). You are also given the equation to calculating the distance, so this question should be easier. The question is when the time where the distance is 60 ft. So the answer would be:

distance= 300-48t
60 = 300ft- 48t
48t= 300- 60=240
t= 5

If n - 2y = 3y- n/m,find the value of n when y = 5 and m = -3
Gnom [1K]

Answer:

37 1/2

Step-by-step explanation:

n - 2y = 3y- n/m,

find the value of n when y = 5 and m = -3

--------

n-2*5=3*5-n/-3

n-10=15+n/3

n-n/3=15+10

2n/3=25

2n=3*25

n=75/2

n=37 1/2 or 37.5
