Answer:-13/3

Step-by-step explanation:

-26/6=6x/6

x=-13/3

Step-by-step explanation:

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

4x+ y= 3

y= -4x + 3

slope = -4

the new slope = 1/4

the equation formula y= mx+b

m = new slope

y = (x/4) + b

From the point given (4,-3)

y = -3. x = 4

-3 = 1 + b

b = -4

the equation =

[tex]y = \frac{1}{4} x - 4[/tex]

Answer:

x-intercept: x = 8/3

y-intercept: y = 8

Step-by-step explanation:

x-intercept

[tex]y = 8 - 3x[/tex]

[tex]0 = 8 - 3x[/tex]

[tex]3x = 8[/tex]

[tex]x = \frac{8}{3} [/tex]

••••

y-intercept

[tex]y = 8 - 3x[/tex]

[tex]y = 8 - 3 \times 0[/tex]

[tex]y = 8[/tex]

Given, K is the midpoint of JL. So, JK = KL.

________

JL = JK + KL (given that K is the midpoint of JL)

JL = (8x + 11) + (14x - 1)

________

[tex] \large \boxed{\mathfrak{Steps} \downarrow}[/tex]

[tex] \sf( 8 x + 11 ) + ( 14 x - 1 )[/tex]

Combine 8x and 14x to get 22x.

[tex] \sf \: 22x+11-1 [/tex]

Subtract 1 from 11 to get 10.

[tex] \boxed{ \boxed{ \bf22x+10 }}[/tex]

________

Also given that, JK = KL.

So, (8x + 11) = (14x - 1)

⇨ (8x + 11) = (14x - 1)

⇨ 8x + 11 = 14x - 1

⇨ 11 + 1 = 14x - 8x

⇨ 12 = 6x

⇨ x = 12 / 6

⇨ [tex] \boxed{ \boxed{ \bf \: x= 2 }}[/tex]

________

Now, value of JL will be,

JL = 22x + 10

Substitute the value of x.

JL = 22(2) + 10

JL = 44 + 10

[tex] \boxed{ \boxed{ \bf\: JL = 50 }}[/tex]

⇨ So, the value of JL will be 50 units.

Answer:  x = 35

Step-by-step explanation:  The sum of all the angles is equal to 360.

2*(x+y+5)+y+2x=360

Opposite angles are equal:  y = 2x

Substitute y=2x into the first:  4x+6x+10 = 360:  x=35 (y = 70)

Answer:

  C.

Step-by-step explanation:

The transformation ...

  g(x) = f(ax)

represents a horizontal compression of the graph by a factor of 'a'. Here, the original function graph is compressed by a factor of 3 horizontally, so the curve will look a lot narrower.

The appropriate choice is C.

Answer:

1. 12x+7

2. x=7

Step-by-step explanation:

1. 4(5x-1)-8x+11=?

multiply 4(5x-1)

20x-4-8x+11

Subtract 8x from 20x which is 12x

then subtract 4 from 11 which is 7

12x+7

Answer:

Step-by-step explanation:

4(5x - 1) - 8x + 11

= 20x - 4 - 8x +11

= 12x + 7

-5(x + 1) + 3x = 6 - (4x - 3)

↔ -5x - 5 + 3x = 6 - 4x + 3

↔ -2x - 5 = 9 - 4x

↔ 2x = 14

↔ x = 7

Answer:

No

Step-by-step explanation:

In order to find if they are scale copies we need to check if the ratio betwenn the two lengths and between the two widths are equal.

The ratio of the lengths is 12 : 15 = 4 : 5

The ratio of the widths is  8 : 8 = 1: 1

Since th ratio are different then the are not scale copies.

Step-by-step explanation:

1/2×1/2×1/2×1/2...............

Step-by-step explanation:

They are parallel.

Parallel lines have the same slope.

for the line y = -2x + 1 the slope is -2 and when we put the line 2x + y = 5 in general equation it will be y = -2x + 5, and it's slope is also -2.

Therefore, the lines are parallel

Answers:

Final Velocity = 20 m/s

Distance Traveled = 50 meters

======================================================

Explanation:

The truck starts from rest, so its initial starting velocity is 0 m/s. I'll denote this as Vi = 0.

The final velocity is what we want to find, so we want to solve for Vf.

The acceleration is a = 4 m/s^2.

The change in time is t = 5 seconds.

So,

a = (Vf - Vi)/(t)

4 = (Vf - 0)/5

4*5 = Vf

20 = Vf

Vf = 20

The final velocity is 20 m/s.

---------------------

Now let's calculate the distance traveled using the following kinematics equation:

d = 0.5*(Vi+Vf)*t

d = 0.5*(0+20)*5

d = 0.5*(20)*5

d = 10*5

d = 50

The truck travels a total distance of 50 meters.

---------------------

This is another way to calculate the distance traveled where we don't need to find Vf

d = Vi*t + 0.5*a*t^2

d = 0*5 + 0.5*4*5^2

d = 0 + 2*25  

d = 50

However, since your teacher wanted you to compute Vf, I think you should stick to the previous set of steps.

Answer:

1

Step-by-step explanation:

6 - 5(2x-3) = 4x + 7

-5(2x-3) = 4x + 1

-10x + 15 = 4x + 1

-14x = -14

14x = 14

x = 1

A Distance between 1st tree and 2nd tree is 5m

similarly it's 10m between 1st and 3rd trees and so on.

So, the total distance between the first and last tree will be :

[tex] \hookrightarrow \: (n -1) \times d[/tex]

where,

[tex] \hookrightarrow \: (20 - 1) \times 5[/tex]

[tex] \hookrightarrow \: 19 \times 5[/tex]

[tex] \hookrightarrow \: 95[/tex]

Therefore, the distance between first and last tree is 95 m.

Answer: 6

Step-by-step explanation:

From the prime factorization of 54 you get:

54 = 2×3×3×3

So ,

You can write it as,

54 = 2×3^2×3,

Make sure all of the factors are in square form, so we add a another 2 and a three to the factors to make them all in square form

You get

=2×3^2×3×2×3 (the last 2×3 is added because one 2 and 3 were not having another pair so they were added to make them squares)

So k is basically 2×3 which is 6

And 54×6 gives us 324, which is a perfect square.
