Answer:

x=-8, x=1/4, x=5.

Step-by-step explanation:

The degree is 3, so there must be 3 roots.

factor: x^2(4x-1)+3x(4x-1)-40(4x-1)=0

=(4x-1)(x^2+8x-5x-40)=0

=(4x-1)(x+8)(x-5)=0

x=1/4, -8, 5

The equation of a line u parallel to given equation of a line is y=1/7 x + 5.

Given that, the equation of line t is y=1/7 x-2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

We know that, standard form of equation of a line is y=mx+c

Now, compare y=1/7 x-2 with y=mx+c, we get m=1/7

The slope of a line parallel to given line is m1=m2

So, slope of a parallel line is m=1/7

Put m=1/7 and (x, y)=(7, 6) in y=mx+c, we get

6=1/7 (7)+c

⇒ c=5

Substitute m=1/7 and c=5 in y=mx+c, that is

y=1/7 x + 5

Therefore, the equation of a line u parallel to given equation of a line is y=1/7 x + 5.

Answer:  Y= -1/7 x + 7 is the correct answer.

Answer:

Step-by-step explanation:

See attached image

Step-by-step explanation:

V=d/t; where;

V: speed (miles per hour)

d: distance (miles)

t: time (hour)

t=d/V=200/40=5 hours=300 min= 18 000 sec.

Answer:

the journey takes 5 hours

Step-by-step explanation:

time taken = distance / time taken

                  = 200 / 40

                  = 5 hours

Answer:

(a) Proof explained below

(b) The two lines are parallel

Step-by-step explanation:

(a) In the second equation express [tex]x[/tex] in terms of [tex]y[/tex] to get:

[tex]x=2y-8[/tex]

Then, substitute [tex]x[/tex] for [tex]2y-8[/tex] in the first equation to get:

[tex]3(2y-8)-6y=-12[/tex]

Open parentheses using the distributive property ([tex]a(b-c)=ab-ac[/tex]) which results in:

[tex]6y-24-6y=-12[/tex]

Combine like terms to reach:

[tex]-24=-12[/tex], which is not true. Therefore, for any values of [tex]x[/tex] and [tex]y[/tex], the systems of equations will have no solutions.

Since the two lines have no solutions, that means that they are parallel.

Option D

Step-by-step explanation:

9x=7x+14

9x-7x=14

2x=14

x=7

Step-by-step explanation:

first term(a)=3

common difference(d)=t2-a

                                    =12-3

                                   =9

now,

T52=a+(n-1)*d

     =3+(52-1)*9

     =462

Therefore,the 52nd term of the arithmetic sequence is 462.

The 52nd term of the arithmetic sequence -3, 12, 27, will be 762.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The arithmetic sequence is given below.

-3, 12, 27, ...

The first term of the arithmetic sequence is negative 3. And the common difference of the arithmetic sequence is given as,

d = 12 - (-3)

d = 12 + 3

d = 15

The equation is given as,

aₙ = -3 + (n - 1) × 15

aₙ = -3 + 15n - 15

aₙ = - 18 + 15n

The 52nd term of the arithmetic sequence -3, 12, 27, will be given as,

a₅₂ = - 18 + 15 × 52

a₅₂ = - 18 + 780

a₅₂ = 762

The 52nd term of the arithmetic sequence -3, 12, 27, will be 762.

Answer: J

Step-by-step explanation: hope its correct

Hi!

The answer to your question would be J

Here's the math to prove it:

Step 1) You need to add all of the number of tiles together.

9+7+3+6=25

Step 2) You need to take each of your tile numbers and divide them by 25.

9/25=0.36 So F would be true

7/25=0.28 So G would be true

6/25=0.24 So H would be true

3/25=0.12 So J would be not true.

I hope this helps!

Have an amazing day/night!
